This is a technology forum where we share our experiences with the Java Enterprise Edition Technologies. We have been working with Middleware Application Servers like JBoss, WildFly, WebLogic. While working on those application servers, design, planning, troubleshooting and coding we found that some of the information’s/posts/articles can be shared to a larger audience as part of this forum which can help other Middleware admins/engineers/developers and architects to make their life easier.
This is just an attempt to make a community where all of us can come together and share your findings, discuss your issues and can help others by responding to their queries.

Hey Jay,
Excellent work, appreciate it!!! My 2 cents to you 🙂
Some suggestions, please add the samples for the following:
a) How to use Shared Libraries in weblogic server
b) Retrieving Server details such as server name, listen address using JMX
c) EJBs using composite primary key class
d) Simple example of Hibernate/JPA
e) Internationalization
f) JTA using distributed transactions
Thanks

NullPointerException happening in application code when run on 64 bit JRockit 1.5.0_17.
Seeing NPE’s at places where we just check if the object itself is null (without accessing any of the object’s members). We suspect this maybe due to some HotSpot optimization techniques and need your help to resolve the issue.
Here are the server details:
================
Windows 2003 x64 SP2
8GB RAM
### Steps to Reproduce ###
Sample code that throws the NPE:
====================
public static List getValue() {
List ctrList = retrieveDateFromDB();
String oldStr = null;
boolean multiStr = false;
Iterator it = ctrList.iterator();
while (it.hasNext()) {
Container item = (Container)it.next();
if (multiStr == false) {
String newStr = item.getInvoiceNum();
if (newStr == null) {
newStr = “”;
}
if (oldStr == null) { // NPE happens on this line. Doesn’t make any sense //
oldStr = newStr;
} else if (oldStr.equals(newStr) == false) {
multiStr = true;
}
}
// Some more code….
return ctrList;
}
Upgraded from 32 bit JRockit to 64 bit JRockit
Product Versions
Weblogic 9.1
java version “1.5.0_17”
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_17-b04)
BEA JRockit(R) (build R27.6.3-40_o-112056-1.5.0_17-20090318-2104-windows-x86_64, compiled mode)
Any pointers……
December 13th, 2009 on 1:39 pm
It Seems to be a BUG with JRockit 64-Bit version…As you have mentioned that the Same Code is working fine with JRockit 32-Bit version.
I tried to reproduce it at my end but i am not getting this kind of NullPointerException…May be My TestCase is not good…
Please get the Exact TestCase and File a JRockit BuG.
December 13th, 2009 on 2:06 pm
Thanks Joy,
Will request for exact test case and will try to to reproduce at my End.
Will even share the test case in the forum.
If able to reproduce i will file a bug.

Hi Jay,
I have a query, we are using Oracle 10.3 WLS with CLuster+Apacahe load balancer.
We are facing below error
1. Broken Pipe
2. Web logic thread stuck issues because of JDBC queries, but one thing I have observed is whenever we start facing thread stuck, it start impacting the WLS Connection pool, and also start causing problem to other threads/queries which are properly optimized, and after some time WLC connection pool goes out of connections or getting exhausted,
Please guide here.
January 4th, 2010 on 7:05 am
Hi Rakesh,
it is very difficult to findout the root cause without looking at the Thread Dump…And the ConnectionPool Setting(DataSourceName.xml) file. But Still As u have mentioned that U are observind STUCK THREAD on JDBC calls…Please recheck the Stack Trace If somewhere u can see “oracle.jdbc.driver.T4CPreparedStatement.doOall8“.
Are u using Oracle Thin JDBC Driver Version 10.2.x Or Later….Please try using WebLogic provided Driver Just for testing…I have seen Some Issues with “oracle.jdbc.driver.T4CPreparedStatement” Class of Oracle JDBC driver 10.2.x..Causes HANG And Stuck Thread….Anyway that is only one possibility.
Are you Getting “ResourceLimitException” as well …by chance?
———–
About the BrokenPipe Error : This error we usually see when there is a Network Fluctuation…Or network Issue…can u Please Specify Exactly when in Which Server Log u are able to See this Error? Going through the Log will really help a lot to Understand that Which Network we need to check…
Thanks

Hi Jay, I have been on your website twice in the last 3-4 days. Your work is indeed very helpful and with time I hope it grows into a repository of resolutions. Anyway, I have an issue with Weblogic 10 right now, I have posted about it here. It would be super nice of you if you can help me with it by giving your inputs. Thanks and keep up the great work.

Hi Aditya,
In 95% cases i have seen that this issue occurs when we upgrade our application from WLS8.1 … If our Application Uses some Controls or WebLogic Specific Annotations …
I remember while upgrading my Application ….”annotations-manifest.xml” file was generated in “WAR/WEB-INF/” directory rather than …”EAR/META-INF” firectory in Workshop…When i pasted it in correct location (EAR/META-INF)…the issue got resolved..
When i was working for Oracle Support … Once i got the similar issue… Which was resolved by adding (Project—>Properties—>Java Annotation Processing Support 5.0) In workshop….At the same time i deployed the required WebLogic Shared Libraries to all the Servers/Clusters where we intended to Deploy our Applications.
Once i resolved this kind of issue by adding a Dummy “EAR/META-INF/weblogic-application.xml” file…By My Own…
I think this is an Issue with Oracle WebLogic Product when we use Workshop…They should fix it.
Keep Posting…
Thanks

Hi Jay,
Your site is really amazing and very helpful for me , now involved in Weblogic upgrade from 9.x to 10.3.
I just tried to use the upgrade utility to upgrade my domain to 10.3, but it did not work. I dont want to manually adjust my config.xml etc.
Is there any way we can achieve this task?

Hi Joy,
It is a very good site that I have ever come across… I hereby request you to help me out in guiding / giving pointers in solving the two issues which is exactly similar to the ones posted in Oracle forums.
In short the errors are about – after creating a weblogic domain with two managed servers on two different machines, ( admin and one managed server are on one machine and the other managed server is on the other machine). I try starting the managed server from the admin console and overcome exceptions and the server never comes to running state. Similar posts in forums are here,

January 30th, 2010 on 1:17 pm
Hi SoumyaSree,
*OPTION-A)*
If you are able to start the Managed Server using …the Start Scripts then it means that the Missing class gets included in the Server Classpath ….when we use StartScripts to Start the Server.
If above one works fine…then Just try the following..
Step1). Open the “nodemanager.properties” file and then “startScriptEnabled=true” and “startScriptName=startWebLogic.cmd” ….provide these two entries there….remember if you are using any custom scripts to start your managed server …then give that scriptname in “startScriptName” parameter..
Step2). restart the Node Manager and then try to start the Managed Server from Admin Console.
—————————
*OPTION-B)*
Start the ManagedServer using the StartScripts and then open the server OUT file….
Find the value of CLASSPATH in that OUT File …copy the CLASSPATH Value and then Login to Admin Console….
Servers—>Click on ServerName (Example MS1)—> configuration Page —> ServerStart (TAB)
In this page Paste the CLASSPATH Value which u have copied….in the CLASSPATH Test Field…
Now restart your Server using AdminConsole.
Thanks

Thank you very much. I could see the managed server running.
While I was creating a domain configuring the default sources cgpool
etc in Oracle …after the set up process is over , I started the admin server and noticed few exceptions ….
<> <Dynamic invocation while executing action updateDeployments on va_intdomain:Location=intAdminServer,Name=AdminServer,Type=ServerConfig MBean instance failed. The method updateDeployments with signature [] was invoked with parameters as [].

Due to this exception the admin server doesnt start up . Can you help me out why this occured and how to fix this ?
Thanks,
Soumya
February 4th, 2010 on 4:37 pm
Hi Soumya,
The error which your are getting complaining about missing “WLI_USER” table. This is most important table in case of WLI domains. The WLI domains Startup class checks the presence of this table in the Database where cgPool datasource is configured.
So to debug this issue please follow the below mentioned steps:
Debug-1). In the Pointbase Database…Please check that the Table “WLI_USER” is existing or not?
If the Table doesn’t exist in the Database then Create all the required Tables in the database by running the script provided by WebLogic in the following location:
//integration/dbscripts/pointbase/wli_runtime.sql
//integration/dbscripts/pointbase/wli_archive.sql
Debug-2). If your server is running in Development mode and if the DataSource (cgPool) points to Pointbase database….then Please start Pointbase database before starting the AdminServer.
Keep Posting 🙂

Hi Jay,
Thanks for a wonderful blog. I need some thing on JMX in WLS 10.3.
How to access the custom MBeanServer out side of the server which was created using
MBeanServerFactory.createMBeanServer(“mydomain”);
I mean what is jmx url or what is the way to connect to that custom MBeanServer from outside.
Thanks

February 16th, 2010 on 6:07 am
Thanks. But the sample whatever you pointed out is to register the custom Mbeans to the existing MBeanserver (Runtime MBeanServer in this case). But my usecase to create my own MBeanServer by using MBeanServerFactory.createMBeanServer(“mydomain”). If we create a MBeanServer like this, then how to get the connection for this MBeanServer from outside.
Thanks

hi .. thats a great blog for weblogic .. keep it up ..
i have a problem with ejbs on weblogic ..
we are migrating from 9.2 to 10.3 weblogic version .
i have compiled all the classes and stubs with 10.3 version .
we call this ejb from a jsp and it throws a cast exception .
java.lang.ClassCastException: com.sync.ejb.ClusterSync_7ujwwg_HomeImpl_1032_WLStub cannot be cast to com.sync.ejb.ClusterSyncHome
interestingly it works from my standalone program in the workshop . can you help me out in this ?
March 4th, 2010 on 1:17 pm
Hi Pavzie,
I have few questions..
1). Which kind of EJBs are these? Like EJBs 2.x or EJB3.x
2). Stateless/Stateful….etc
3). Are u deploying these EJBs over Cluster?
4). The Jsp from which u are trying to access these EJBs is that part of the Same EAR or a Separete Client Application?
5). Can u Please provide the Deployment Descriptors of the EJBs…like “ejb-jar.xml” and “weblogic-ejb-jar.xml”?
6). The Code snippet of your JSP which access the EJB?
7). And Can u please paste the complete StackTrace of the ClassCastException sothat it will be easy to check that which APIs are getting involved here?
These informations will be really helpful to understand the actual issue.
Thanks

Hi Jay,
Hope your are doing well
I have an issue wherein I am trying to use the SUN STAX implementation by putting following parameters in the java options.
-Djavax.xml.stream.XMLInputFactory=com.sun.xml.internal.stream.XMLInputFactoryImpl
-Djavax.xml.stream.XMLOutputFactory=com.sun.xml.internal.stream.XMLOutputFactoryImpl
-Djavax.xml.stream.XMLEventFactory=com.sun.xml.internal.stream.events.XMLEventFactoryImpl
When I have these parameters the server takes forever to startup.
I believe the culprit to this situation is the following thread that is runs to validate the DTD for XML parsers.

When we are using the sun parser, it’s trying to connect to the sun’s server to get the DTD for validation of the xml.
It could well be that the Sun Servers are down at that time or some problems at the Sun Servers end.
It’s actually an expected behavior, or rather, a shortcoming of the sun’s parser which should have allowed some config settings to save/use local copies of DTD for validation.
Is there any way in which we can turn-off the DTD validation?? Do we have any flag for that?

Hi Jay,
I’m a trying run the example of JMS over JAX-WS but I can’t. I’ve working in this issue several days and not found the solution.
Maybe, is a small problem or some detail in a configuration file or XML (or someting about JMS), but I can’t find the solution to run this example sucessfully.
I’m reading some entries of your blog and I see that you are an expert in these issues. I write an entry in this forum but now nobody have a solution.
http://forums.oracle.com/forums/thread.jspa?threadID=1020087&tstart=0
Could you help me?
(if you have an example or something similar (a zip file with an example), or anything – I’m desperate and need some help )

Hi Vijay,
This kind of problems happens only in Unix Based OS…
Please make sure that BEA_HOME is not specified in “.profile” file (you may find it in your $HOME) or in environment setup.
If the “Super User” has installed the BEA_HOME on your Box then you need that right to startWebLogic Server. Please check With which user account the BEA_HOME was installed.

Hi,
I am using wsimport to generate a service using a standard WSDL. The service itself is an EJB 3.0 based JAX-WS web service.
After generating the service we try to deploy it to WLS server and the deployed service is exposed using a URI which is not the expected one.
Expected service URI is http:///ARService. But the service URI after deployment comes out to be http:///ARService_ServiceImpl/ARService.
The main reason we want the URI to be same is because we need to deploy it to multiple servers i.e. Sun, JBoss and WLS.
Even when we try to deploy the same application on these three servers we get different service URIs.
Weblogic 10.3 => http://localhost:7001/DemoImpl/demo?wsdl
Glassfish 2.1 => http://localhost:7001/demo/DemoImpl?wsdl
(The order of the URI components demo and DemoImpl is flipped between glassfish and weblogic)
JBoss 5.1 => http://localhost:8080/webservice-webservice/DemoService?wsdl
I have already verified these behaviors.
Now as per these findings it seems as if there are no standard in terms of the end service URIs across these containers.
I have also confirmed that using JWSC is not an option since we want the same service to be deployed on multiple servers (the three mentioned above). I have also tried using the javax.jws.WebService.serviceName and javax.jws.WebService.name but it didn’t create any difference in the end behavior.
Do we have any option of specifying the service URI out-of-box in weblogic by which we can specify the required URL, without using WLS specific ant tasks?
Also please let me know why the same application has different URI’s? Are there no standard ways in which the different containers should behave to generate the service URI?
Any pointers will be of great help.

Hi Jay
I came across your website/bolg while I was looking for some information on issues tied to weblogic 8.1 and active directory authentication.
I hope you dont mind me asking you. We have 8 weblogic servers that all authenticate users using the active directory. Recently 4 out of the 8 weblogic servers were not allowing users to log to the application. I dont see any errors except for 403s in the access log.
Looks like something went wrong between those weblogic servers ( running on IBM AIX ) and the external active directory. Is there any setting in weblogic that I can turn on to see what might have been going on at that time? when the user types the id and password, the screen goes balnk for a few minutes and returns with the same login page.
I havent seen anything unusual in the logs and hence am looking at experts on weblogic to help me put here with any suggestion.
Please let me know
thanks

May 19th, 2010 on 4:44 am
Hi Karthi,
WebLogic Is a Java Based Application Server and most of it’s APIs/JMX implementations are also written and implemented in Java Language only. So far there is no API or extension available which will allow a VB.Net client to Create/Configure/Manage/Monitor the Servers/Domain/Deploy Apps/ or to create dataSources.
We need to use WebLogic’s Java based APIs to acheive this. Using Native code it can be achieved …to interact with WebLogic’s Java Code But it will require a very Big Framework to do so. So far there is no organization/team working on this kind of interoperability.

Hi Sarath,
First of all i m very sorry for my late response…i was bit involved in some critical production issues…
Please try the below….
To Target AdminServer your can do the Following:
edit()
startEdit()
cd(‘/SystemResources/TestDS’)
set(‘Targets’,jarray.array([ObjectName(‘com.bea:Name=AdminServer,Type=Server’)], ObjectName))
save()
activate()
To Untarget you need to do the following pass the Null jarray like following:
edit()
startEdit()
cd(‘/SystemResources/TestDS’)
set(‘Targets’,jarray.array([], ObjectName))
save()
activate()

I am new to this site and do not know where to post my query.
we are considering to add a new component to our existing Swing application which enables to monitor JMS traffic. I heard it is easy to implement via JMX;I am new to JMX can you please provide some information on JMX. We are using Weblogic Server 10.0 MP1
1. Is JMX is part of JEE specification?
2. Is JMX code [instrumented to monitor JMS Destinations & EJBs] portable across various Application servers?
3. How much effort required adding new code or modifying existing code while porting to new App servers?

Hi
Can you please tell me why connection pool has added inside data souce from weblogic version 9.x onwards (as we know weblogic 8.x it was separte) ,recently I have faced this question from interviewer .
how can I answer this question please tell me .
Thanks
Balaji kumar
October 14th, 2010 on 10:54 am
Hi Balaji,
DataSource and Connection Pool always work together. Functionality wise there is no change happened in DataSource/Connection Pool from WLS8.x to WLS9.x onwards. But then only Difference you will see that from WLS9.x onwards In the AdminConsole You need not to separately create the Connection Pool. In WLS8.1 We used to create the Connection Pool with all the Database details/Url/DBUsername/DBpassword…and then once the Connection Pool is created Successfully we used to create a DataSource to assign it a Unique JNDI name and then we used to assign the ConnectionPool to the DataSource.
But From WLS9.x Onwards to make it more simple and in One Sequence of Enevts…we made this changes. Now While creating the DataSource itself you need to provide all the Database details/Url/DBUsername/DBpassword as well as the JNDI name. So This change is only for Users Simplicity.
Apart from this there has been a Major Change in the JDBC Module of the WebLogic Container from WLS9.x onwards … That is called as “MultiDataSources”.This feature has been introduced In WebLogic 8.1 Similar feature was available with name “MultiPool” … So to made some enhancement in MultiPool feature they have introduced “MultiDataSource” concept from WLS9.x onwards. Which allows as to even control the Failover of MultiDataSource on our own by writing the our Own Handler….Please refer to : http://middlewaremagic.com/weblogic/2010/05/15/controlling-multidatasource-failover/ for more details.

please reply to my id (k8.suresh@gmail.com)
March 1st, 2011 on 7:06 pm
HI sburavel,
The main cause of you issue/ crash is because of the SIGBUS signal.
SIGBUS:
SIGBUS is the signal sent to the process when a bus error occurs, now bus error can occurs when the hardware get a notification by the OS like (Unix-like Operating system) when it sense a memory access violation. The main issue for memory access violation can happen due to the following reasons
1) Invalid address alignment
2) Non-existent physical address
3) Object-specific hardware error
More information can be found in the below link:
http://en.wikipedia.org/wiki/SIGBUS
However JVM take cares of the memory allocation which is on top of any OS and on JVM any JAVA based application can run (like WLS) hence the main culprit here is the JDK which you are using. I can see that that you are using SUN JDK 1.5.0_10, hence would suggest you to upgrade your JDK with the latest JDK for 1.5 UPDATE.

WLSSPI-0011.1: % of execute queue threads used (100.00%) too high (>= 90.00%) [Policy: WLSSPI_0011]
can u plz suggest this issue, is it critical or not ,
can we tune any parameter in weblogic plz suggest.
July 25th, 2012 on 12:14 pm
Since WebLogic 9.2 the threadpool is self managing, i.e., when the need arises it will create more executethreads.
By using work managers you can trottle the threadpool on an application basis.
An example is given here: http://middlewaremagic.com/weblogic/?p=5665 in the ‘EJB processing’ section.
It also gives an explanation on what is going on internally.
July 27th, 2012 on 12:58 am
Hi René,
in my environment we are using only one application in production environment,i am getting execute queue threads used (100.00%)in ticketing tool, because we are created one policy with threshold value.
WLSSPI-0011.1: % of execute queue threads used (100.00%) too high (>= 90.00%) [Policy: WLSSPI_0011]
for this it is generating ticket as incident, to acknowledge this, is there any parameter should i have to change.
by default in production env 25 execute queue thread,how to increase this value.
July 27th, 2012 on 12:50 pm
Note that since WebLogic9.2 the threadpool is self managing, so the when the time is ripe it will create the extra threads.
More information can be found here: http://docs.oracle.com/cd/E11035_01/wls100/perform/topten.html#wp1132662
If you are working with the WebLogic8 thread model, you can find the information you need here: http://docs.oracle.com/cd/E13222_01/wls/docs92/perform/appb_queues.html

Hi Jay/Ravish,
how to reduce socket connections, currently open 7.
&&
open sessions for web application myidm (110.00) too high (>= 100.00)
how to reduce this open sessions, is there any parameter have i tune in weblogic, plz suggest for the same.
July 27th, 2012 on 12:55 pm
Not sure if you mean this (by socket connections) – you can allocate in the WebLogic8 thread model,
some execute thread to act as socket readers: http://docs.oracle.com/cd/E13222_01/wls/docs92/perform/appb_queues.html#wp1046586.
The link outline the steps to changes the Number of Socket Reader Threads For a Server Instance.
You can set the session-timeout to a lower value. Sessions are created by the application you are running. When a user does
not interact with the application for the session timeout value, the session will be deleted.

Hi René van Wijk,
Thanks for replying to my posts
is it require to change below parameters in weblogic 10.3.5,
-Dweblogic.Use81StyleExecuteQueues=true
So in that Case …config.xml entry will be like this:
AdminServer
weblogic.kernel.Default
256
true
7001
../../logs/admin_access.log
aaa.bbb.com
because we are using service manager ticketing tool , my managent has configure some policy like,
when execute thread queue reaches to 100% it is generating as one incident,daily we r getting this incident, some times ticket was closed automatically because of self tuning by weblogic server which you mentioned above.
is that incident was critical ,(or) is it require to change any parameters in weblogic 10.3.5,
some times when struck thread happen in server that time also we are getting same.
plz suggest above issue.
July 30th, 2012 on 1:52 pm
If I understand you correctly, you are using WebLogic 10.3.5. In this case do not set the weblogic.Use81StyleExecuteQueues parameter.
In WebLogic 10.3.5, the thread management in self managing, meaning it will start with, for example, three threads and when the need
is present it will created new ones.
Note that in this case the monitoring you are doing is somewhat unnecessary. In this case it makes more sense to monitor if threads are getting stuck.
When too many threads are getting stuck (each consuming memory) the environment (WebLogic Server) can run into an out-of-memory error.
Note that WebLogic provides functionality to protect the server from overloading:

to avoid issue what we have to do
WLSSPI-0011.1: % of execute queue threads used (100.00%) too high (>= 90.00%) [Policy: WLSSPI_0011]
still we are getting same issue,& is it require configure work managers for application also?.
plz suggest me

A good post on logging is provided here: http://lzy.sh/b/weblogic-11g-logging-configuration-settings/ but not on .out file rotation
The information the WebLogic documentation provides can be found here: http://docs.oracle.com/cd/E21764_01/web.1111/e13740/overview.htm#i1079068
One thing to note is the following: You cannot limit the size of the log files Node Manager creates. Thus we need something to write ourselves, when your on Linux
you are in luck. In this post: http://myexperienceswithsoa.blogspot.com/2011/12/rotating-out-files-in-soa-11g-weblogic.html a nice script is provided:
”
By default Weblogic doesn’t have options to rotate the *.out file, so if we are running on Linux boxes, we can add the following snippet under /etc/logrotate.conf file and append a function to handle *.out files
(location of logs directory)/*.out {
copytruncate
rotate 5
size=10M
}
Basically the above function rotates the .out file for 5 times,once each file reaches the 10MB size and then it truncates the file.
”

There is something mentioned here (https://forums.oracle.com/forums/thread.jspa?messageID=2693825 and http://dbaforums.org/oracle/index.php?showtopic=990 which includes more details about RAC) about the connect string not being right (do not know if that is
also the case with you, as you did not post the connect string you are using)
“This was caused by my JDBC-string. I used a string like “jdbc:oracle:thin:@DESCRIPTION = (ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = ……
and I should have used “jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = ……
Note that there is a ‘(‘ before DESCRIPTION.”
“ADMIN_JDBC_URL=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=mcharpen-fr-vip.fr.oracle.Com)(PORT=1555))(ADDRESS=(PROTOCOL=TCP)(HOST=suppolite1-vip.fr.oracle.com)(PORT=1555))(LOAD_BALANCE=yes)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl.fr.oracle.com)(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC)(RETRIES=180)(DELAY=5))))”

I have two machines connected via wireless router. Both can ping each other. My node manager is up and running in one machine. I logged into the admin console from the other machine and found that the node manager is reachable. But when I am trying to start the admin server using nmConnect(), I am getting the following error
WLSTException: Error occured while performing nmConnect : Cannot connect to Node
Manager. : [Security:090476]Invalid/unknown SSL header was received from peer D
ESKTOP-HUCQUK5 – 192.168.0.5 during SSL handshake.
Use dumpStack() to view the full stacktrace.
Here 192.168.0.5 is the ip of the machine in which the node manager is running.
I have set the node manager type as plain, and host name to none from my admin console. In the nodemamager.properties file I have set the securedListener as false. But still no result.

Hi,
I have two domains configured on different physical servers. Domain 1 hosted with weblogic server and is clustered. Doamin 2 has Weblogic and OHS server. Domain has a java application deployed on weblogic. Domain 2 has some other java applications and some image stored on a directory. Through url i can login and a jsp will display all the required information. An Ecard is displayed and all the images are shown as expected. While to try to download this Ecard into PDF, a PDF gets generated but it has to comeup with the image on it, which is missing. If i restart and try to download PDF, i get image on PDF. But at peak time this not happening. Below i have posted the error message.

I have done wget to get the image from domain1 and is successful to download the image. Through jsp on browser i am able to see the image. Its only when downloading PDF this error occurs. But after restart it is fine for some time. Could you please provide your valuable inputs on this. I suspect the response is timing out due to domain 2 slow response. If that is the case, what parameter needs to tuned in this case. Really appreciate your response on this. Looking forward for your valuable inputs.

Hello Noor,
If the PDF size is too large then i am suspecting that your N/W firewall setting Or Network rules might be causing the “HTTP response code: 504”.
As per the RFC specification on HTTP: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
10.5.5 504 Gateway Timeout
The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server specified by the URI (e.g. HTTP, FTP, LDAP) or some other auxiliary server (e.g. DNS) it needed to access in attempting to complete the request.
So please try with a smaller size of PDF and then find out if the size of PDF is causing any issue or not.
If you are facing this issue with all size of PDF files downloading then you should also check if your application has the mime type defined properly inside the “WEB-INF/web.xml” file or not?
<mime-mapping>
<extension>pdf</extension>
<mime-type>application/pdf</mime-type>
</mime-mapping>
Regards
