Writing WebLogic 12c based EJB 3.0 project and Standalone client using Maven Build

Hi,

As part of this demo we will see how to write a fully maven based WebLogic12c deployable application which will contain an EJB Project which we will deploy on WebLogic using the 12c specific maven plugin “wls-maven-plugin”. In the same sample we will use the “exec-maven-plugin” plugin as well to run our Remote Weblogic EJB Client code.

As part of this code was we will learn the following things:

1). Writing a simple EJB EAR project using Maven.
2). Deploying the EAR project on WebLogic 12c using “wls-maven-plugin”
3). Running a Simple EJB Client code with the help of “exec-maven-plugin”

So lets begin with writing the EJB Project.

Developing EJB Project

Step-1). First of all lets make a directory “WebLogic_EJB_Demo_Using_Maven” where we will keep both our “EJB_Project” and “EJB_Client_Project”.

    $ mkdir /WebLogic_EJB_Demo_Using_Maven
    $ mkdir -p /WebLogic_EJB_Demo_Using_Maven/EJB_Project/TestApp/src/main/application/META-INF
    $ mkdir -p /WebLogic_EJB_Demo_Using_Maven/EJB_Project/TestEJB/src/main/java/ejb3

Step-2). Now we will write the “HelloRemote.java”, the remote interface of our Stateless EJB, Inside the “EJB_Project/TestEJB/src/main/java/ejb3”.

package ejb3;
import javax.ejb.*;
@Remote
public interface HelloRemote {
        public String sayHello(String name);
}

Step-3). Similarly we will write the Stateless Bean “HelloBean.java” inside the “EJB_Project/TestEJB/src/main/java/ejb3” as following

package ejb3;
import javax.ejb.*;
@Stateless
public class HelloBean implements HelloRemote {
        public String sayHello(String name) {
           System.out.println("\n\t hello("+name+") invoked, Hello HelloBean Date:  "+new java.util.Date());
           return "Hello, "+name+", Date: "+new java.util.Date();
        }
 }

Step-4). Now we will write the most important part. So lets create a maven build the file “pom.xml” inside the “/WebLogic_EJB_Demo_Using_Maven/EJB_Project/TestEJB” directory.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Step-5). Similarly we will write another “pom.xml” inside the “/WebLogic_EJB_Demo_Using_Maven/EJB_Project/TestApp” as following:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

Step-6). So far we have written the child project pom.xml, Now lets write the main “pom.xml” file inside the “/WebLogic_EJB_Demo_Using_Maven/EJB_Project” as following:

               <configuration>
                  <source>1.7</source>
                  <target>1.7</target>
               </configuration>
            </plugin>

            <plugin>

            </plugin>  
         </plugins>
     </build>
     
</project>

Step-7). Now lets start the WebLogic server and then deploy the EJB project. In order to deploy the EJB Project, Open a terminal and then run the following commands. The Maven plugin will build the EAR containing the EJB as well as it will deploy it to WebLogic server.

For Unix Based OS

$ export M2_HOME=/PATH/TO/apache_maven_3.2.3
$ export JAVA_HOME=/PATH/TO/jdk1.8.0_60
$ export PATH=$JAVA_HOME/bin:/PATH/TO/apache_maven_3.2.3/bin:$PATH

$ cd /WebLogic_EJB_Demo_Using_Maven/EJB_Project
$ mvn clean install wls:deploy 

For Windows Based OS

$ set M2_HOME=C:\PATH\TO\apache_maven_3.2.3
$ set JAVA_HOME=C:\PATH\TO\jdk1.8.0_60
$ set PATH=%JAVA_HOME%/bin;C:\PATH\TO\apache_maven_3.2.3\bin;%PATH%

$ cd C:\WebLogic_EJB_Demo_Using_Maven\EJB_Project
$ mvn clean install wls:deploy 

In case if you face any error / exception while running the WebLogic 12c Maven plugin “wls-maven-plugin” then please refer to the article:

Writing WebLogic EJB Client Code

Step-8). Now lets start writing the client project. So first of all lets make the following directories:

$ mkdir -p /WebLogic_EJB_Demo_Using_Maven/EJB_Client_Project/src/main/java/ejb3
$ mkdir -p /WebLogic_EJB_Demo_Using_Maven/EJB_Client_Project/src/main/java/client
$ mkdir -p /WebLogic_EJB_Demo_Using_Maven/EJB_Client_Project/src/main/resources

Step-9). Now lets first place the above created “HelloRemote.java” inside the “/WebLogic_EJB_Demo_Using_Maven/EJB_Client_Project/src/main/java/ejb3” directory so that the client can use it.

package ejb3;
import javax.ejb.*;
@Remote
public interface HelloRemote {
        public String sayHello(String name);
}

Step-10). Now the main step of writing the EJB Client. So lets create a file “WebLogicEJBClient.java” inside the “/WebLogic_EJB_Demo_Using_Maven/EJB_Client_Project/src/main/java/client” as following:

package client;
import javax.naming.*;
import java.util.*;
import ejb3.HelloRemote;

public class WebLogicEJBClient {
  public static void main(String ar[]) throws Exception {
    Context context = null;
	try {
          Properties props = new Properties();
          props.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
          props.put(Context.PROVIDER_URL, "t3://localhost:7001"); 
          //props.put(Context.SECURITY_PRINCIPAL, "ejbUserOne");
          //props.put(Context.SECURITY_CREDENTIALS, "ejbPasswordOne@123");
          context = new InitialContext(props);	
          
          System.out.println("\n\n****************************************");
	      System.out.println("\n\t[WebLogicEJBClient] Got initial Context: "+context);	

          String EJB_JNDI_NAME="java:global/TestApp/TestEJB/HelloBean!ejb3.HelloRemote";
          
          HelloRemote remote = (HelloRemote) context.lookup(EJB_JNDI_NAME);
          String result = remote.sayHello("MiddlewareMagic!!!");
          System.out.println("\n\t[WebLogicEJBClient] Got response from EJB : " + result);
          System.out.println("\n****************************************\n\n");
          
     } catch(Exception e) {
			e.printStackTrace();
     }     
   }
}

Step-11). Now lets run the EJB Client code as following:

For Unix Based OS

$ export M2_HOME=/PATH/TO/apache_maven_3.2.3
$ export JAVA_HOME=/PATH/TO/jdk1.8.0_60
$ export PATH=$JAVA_HOME/bin:/PATH/TO/apache_maven_3.2.3/bin:$PATH

$ cd /WebLogic_EJB_Demo_Using_Maven/EJB_Client_Project

$ mvn clean install exec:exec

For Windows Based OS

$ set M2_HOME=C:\PATH\TO\apache_maven_3.2.3
$ set JAVA_HOME=C:\PATH\TO\jdk1.8.0_60
$ set PATH=%JAVA_HOME%/bin;C:\PATH\TO\apache_maven_3.2.3\bin;%PATH%

$ cd C:\WebLogic_EJB_Demo_Using_Maven\EJB_Client_Project

$ mvn clean install exec:exec

RAW Output of Client Code Execution:


$ mvn clean install exec:exec

WebLogic 12c JMS Bridge to connect to WildFly 8.2 HornetQ Broker.

Hi,

As part of this article we will see how to configure a JMS Message bridge on WebLogic 12c side so that any message sent to the JMS Queue present on WebLogic will be automatically transfered to WildFly 8.2 Instance. The WebLogic Messaging Bridge is a forwarding mechanism that provides interoperability between WebLogic JMS implementations, and between JMS and other messaging products. We are going to use the Messaging Bridge to integrate WildFly 8.2 offered HornetQ messaging broker communication. A messaging bridge instance forwards messages between a pair of bridge source and target destinations. These destinations are mapped to a pair of bridge source and target destinations. The messaging bridge reads messages from the source bridge destination and forwards those messages to the target bridge destination.

In order to know how to create a WebLogic Message bridge between WebLogic and JBoss 5 please refer to : http://middlewaremagic.com/weblogic/?p=6066

As part of this article we will learn:

1). How to create a WebLogic Message Bridge using WLST.
2). How to create a JMS Queue on WildFly 8.2 side.
NOTE: These steps will remain almost same for JBoss AS7 or JBoss EAP6, the only change will be in the Connection URL of WildFly or JBossAS. In WildFly we use “http-remoting://localhost:8080” where as in JBossAS7/EAP6 we use “remote://localhost:4447”).
3). Then we will send some messages to WebLogic JMS Queues and will receive them from WildFly 8.2 JMS Queues.

Creating A Simple JMS Queue on WildFLy 8.2 side

Step-1). Start the WildFly 8.2 (or JBoss EAP6/JBossAS7) full profile (which has messaging) as following:

   $ cd /PATH/TO/wildfly-8.2.1.Final/bin
   $ ./standalone.sh -c standalone-full.xml

I am running Weblogic 12c and WildFLy on the same host hence i am running both on “localhost” users can change it based on their need.

Step-2). Create a simple JMS user on WildFly 8.2 side and this user must belong to “guest” role. Please see the “messaging subsystem” configuration of “standalone-full.xml” to know more about “guest” role.
username: jmsuser
password: jmsuser@123
user role: guest
Realm: ApplicationRealm

   $ cd /PATH/TO/wildfly-8.2.1.Final/bin
   $ ./add-user.sh 

What type of user do you wish to add? 
 a) Management User (mgmt-users.properties) 
 b) Application User (application-users.properties)
(a): b

Enter the details of the new user to add.
Using realm 'ApplicationRealm' as discovered from the existing property files.
Username : jmsuser
Password recommendations are listed below. To modify these restrictions edit the add-user.properties configuration file.
 - The password should not be one of the following restricted values {root, admin, administrator}
 - The password should contain at least 8 characters, 1 alphabetic character(s), 1 digit(s), 1 non-alphanumeric symbol(s)
 - The password should be different from the username
Password :  jmsuser@123
Re-enter Password :  jmsuser@123
What groups do you want this user to belong to? (Please enter a comma separated list, or leave blank for none)[  ]: guest
About to add user 'jmsuser' for realm 'ApplicationRealm'
Is this correct yes/no? yes
Added user 'jmsuser' to file '/PATH/TO/wildfly-8.2.1.Final/standalone/configuration/application-users.properties'
Added user 'jmsuser' to file '/PATH/TO/wildfly-8.2.1.Final/domain/configuration/application-users.properties'
Added user 'jmsuser' with groups guest to file '/PATH/TO/wildfly-8.2.1.Final/standalone/configuration/application-roles.properties'
Added user 'jmsuser' with groups guest to file '/PATH/TO/wildfly-8.2.1.Final/domain/configuration/application-roles.properties'
Is this new user going to be used for one AS process to connect to another AS process? 
e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server EJB calls.
yes/no? yes
To represent the user add the following to the server-identities definition <secret value="am1zdXNlckAxMjM=" />

Step-3). Creating a simple JMS Queue using the WildFly CLI command line utility. NOTE the JNDI name should contain “java:/jboss/exported” prefix or else the JMS queue will can not be looked up remotely.

   $ cd /PATH/TO/wildfly-8.2.1.Final/bin
   $ ./jboss-cli.sh -c
   
   [standalone@localhost:9990 /] /subsystem=messaging/hornetq-server=default/jms-queue=TestQ/:add(entries=["java:/jboss/exported/jms/queue/TestQ"],durable=false)
     {"outcome" => "success"}
     
   [standalone@localhost:9990 /] :reload
     {
       "outcome" => "success",
       "result" => undefined
     }

Starting WebLogic 12c and configuring it

First of all Copy the WildFly client jar “/PATH/TO/wildfly-8.2.1.Final/bin/client/jboss-client.jar” and place it inside the “$DOMAIN_HOME/lib” directory of WebLogic 12c.

Step-4). Start WebLogic 12c normally.

   $ cp -f /PATH/TO/wildfly-8.2.1.Final/bin/client/jboss-client.jar     /PATH/TO/wls12130/user_projects/domains/mydomain/lib

   $ cd /PATH/TO/wls12130/user_projects/domains/mydomain/bin
   $ ./startWebLogic.sh

Writing WLST script to configure JMS Bridge

Step-5). Now create a directory like “WebLogic_JMS_Bridge” where we will place our project artifacts.

   $ mkdir  WebLogic_JMS_Bridge
   $ cd WebLogic_JMS_Bridge

Step-6). Inside the “WebLogic_JMS_Bridge” directory write the following kind of file “domain.properties” which will contain all the configuration details.


############ WebLogic 12c JMS Queue and Connection Factory related Configuration #########

# 1 - Connecting details
server.url = t3://localhost:7001
username = weblogic
password = weblogic1
 
# 2 - JMSServer details
jms.server.name = My_JMSServer
store.name = MyJDBCStore
tragated.jms.server.name = myserver
 
# 3 - SystemModule Details
system.module.name = My_SystemModule
tragated.system.module.name = myserver
 
# 4 - ConnectionFactory Details
connection.factory.name = My_ConnectionFactory
connection.factory.jndi.name = My_CF
 
# 5 - Unit Of Order Details
unit.of.order.value = 1
 
# 6 - SubDeployment & Queue Details
queue.sub.deployment.name = Sub_My_Queue
queue.name = My_Queue
queue.jndi.name = My_Q


############ JMS Bridge related Configuration #########
weblogic.destination.bridge = WLS_Source_Bridge
weblogic.adapter.jndi.name = eis.jms.WLSConnectionFactoryJNDINoTX


wildfly.destination.bridge = WildFly_Destination_Bridge
wildfly.server.url = http-remoting://localhost:8080

# When using JBoss EAP6 or JBossAS7 then change the URL to following:
# wildfly.server.url =remote://localhost:4447

wildfly.initial.context.factory = org.jboss.naming.remote.client.InitialContextFactory
wildfly.remote.connection.factory.jndi.name = jms/RemoteConnectionFactory
wildfly.jms.destination.jndi.name = jms/queue/TestQ

wildfly.jms.username = jmsuser
wildfly.jms.password = jmsuser@123

Step-7). Now we will write simple WLST Script to configure the JMS Bridge , Create JMS Queue, JMS ConnectionFactory on WebLogic side. So write a file like “weblogicJMS_Setup.py” inside the same directory “WebLogic_JMS_Bridge” as following:

cmd = "rm -f wlst.log"
os.system(cmd)

Step-8). Now we will run the WLST script. As following:

   $ cd /PATH/TO/wls12130/user_projects/domains/mydomain/bin
   $ . ./setDomainEnv.sh
   $ cd /PATH/TO/WebLogic_JMS_Bridge
   $  java  weblogic.WLST  webLogicJMS_Setup.py
   
   
   
   OUTPUT:

Writing Java Code to send messages to WebLogic JMS Queue

Step-9). Now In the “WebLogic_JMS_Bridge” create a sub directory with name “src” where we will create file “QueueSend.java”:

import java.io.IOException;
import java.util.Hashtable;
import javax.jms.JMSException;
import javax.jms.Queue;
import javax.jms.QueueConnection;
import javax.jms.QueueConnectionFactory;
import javax.jms.QueueSender;
import javax.jms.QueueSession;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class QueueSend {
  public final static String JNDI_FACTORY="weblogic.jndi.WLInitialContextFactory";
  public final static String JMS_FACTORY="My_CF";
  public final static String QUEUE="My_Q";

  private QueueConnectionFactory qconFactory;
  private QueueConnection qcon;
  private QueueSession qsession;
  private QueueSender qsender;
  private Queue queue;
  private TextMessage msg;

  public void init(Context ctx, String queueName) throws NamingException, JMSException {
    qconFactory = (QueueConnectionFactory) ctx.lookup(JMS_FACTORY);
    qcon = qconFactory.createQueueConnection();
    qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
    queue = (Queue) ctx.lookup(queueName);
    qsender = qsession.createSender(queue);
    msg = qsession.createTextMessage();
    qcon.start();
  }

  public void send(String message,int counter) throws JMSException {
    msg.setText(message);
    msg.setIntProperty("counter", counter);
    qsender.send(msg);
  }

  public void close() throws JMSException {
    qsender.close();
    qsession.close();
    qcon.close();
  }

  public static void main(String[] args) throws Exception {
    if (args.length != 1) {
      System.out.println("Usage: java QueueSend WebLogicURL");
      return;
    }
    InitialContext ic = getInitialContext(args[0]);
    QueueSend qs = new QueueSend();
    qs.init(ic, QUEUE);
    readAndSend(qs);
    qs.close();
  }

  private static void readAndSend(QueueSend qs) throws IOException, JMSException {
    String line="Test Message Body with counter = ";
    for(int i=0;i<10;i++) {
          qs.send(line+i,i);
          System.out.println("JMS Message Sent: "+line+i+"\n");
       }
  }

  private static InitialContext getInitialContext(String url) throws NamingException {
    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
    env.put(Context.PROVIDER_URL, url);
    return new InitialContext(env);
  }
}

Step-10). Now we will write a simple ANT “build.xml” file inside the “WebLogic_JMS_Bridge” as following:

<project name="ApplicationLevelJMSDemo" default="run">
<property name="wls.home" value="/Users/jsensharma/NotBackedUp/Installed/wls12130" /> <!-- CHANGE ME!! -->
<property name="basedir" value="." />
<property name="tmp.dir" value="tmp" />
<property name="output.dir" value="build" />
<property name="src.dir" value="src" />
<property name="client.jar.name" value="jms_WLS_Client.jar" />

        <path id="wls.classpath">
             <fileset dir="${wls.home}">
                 <include name="**/*.jar"/>
             </fileset>
        </path>
        <target name="init">
           <delete dir="${output.dir}" />
           <mkdir dir="${output.dir}" />
           <delete dir="${tmp.dir}" />
           <mkdir dir="${tmp.dir}" />
        </target>

        <target name="run">
           <delete dir="${tmp.dir}" />
           <mkdir dir="${tmp.dir}" />
           <javac srcdir="${src.dir}" destdir="${tmp.dir}"  includes="QueueSend.java" classpathref="wls.classpath"/>
           <jar jarfile="${output.dir}/${client.jar.name}" basedir="${tmp.dir}" compress="true" />
           <java classname="QueueSend" fork="true">
               <classpath>
                  <pathelement location="${tmp.dir}"/>
                  <path refid="wls.classpath"/>
               </classpath>
               <arg value="t3://localhost:7001"/>
           </java>
           <delete dir="${tmp.dir}" />
        </target>  
</project>

Make sure to change the “wls.home” to point to your own WebLogic installation in this file.

Step-11). Now lets run the ANT project to send some messages to WLS “My_Q”

     $ cd /PATH/TO/WebLogic_JMS_Bridge
     $ export ANT_HOME=/PATH/TO/apache_ant_1.9.2
     $ export JAVA_HOME=/PATH/TO/jdk1.8.0_60
     $ export PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$PATH
     
     $ ant
     
     
     OUTPUT:
     Buildfile: /Users/jsensharma/NotBackedUp/MM_Tests/WLS/JMS_Bridge/build.xml

Using weblogic 12c specific new wls-maven-plugin

Hi,

As part of this example we will talk about the new “wls-maven-plugin” which is added as part of WebLogic 12c installation. This plugin provides a lots of additional facilities compared to the older “weblogic-maven-plugin” plugin. With the help of “wls-maven-plugin” plugin we can install, start and stop servers, create domains, execute WLST scripts, and compile and deploy applications.

The wls-maven-plugin requires a local WebLogic Server installation. For more information on this please refer to the following link: https://docs.oracle.com/cd/E24329_01/web.1211/e24368/maven.htm#WLPRG692

Update:10-Nov-2015 Unfortunately this plugin is removed in WebLogic 12.2.1, See the review: https://community.oracle.com/message/13400268

Installing “wls-maven-plugin”

Step-1). Open a terminal and run the following command:

$ export M2_HOME=/PATH/TO/apache_maven_3.2.3
$ export JAVA_HOME=/PATH/TO/jdk1.8.0_60
$ export PATH=$JAVA_HOME/bin:/PATH/TO/apache_maven_3.2.3/bin:$PATH


$ export MW_HOME=/PATH/TO/wls12130
$ cd $MW_HOME/wlserver/server/lib
$ mvn install -Dfile=wls-maven-plugin.jar -DpomFile=pom.xml

Step-2). Now install the wls-maven-plugin inside the local maven repository which is by default “~/.m2/repository”. In this case it will be placed inside the following dir “~/.m2/repository/com/oracle/weblogic/wls-maven-plugin”

$ mvn install:install-file  -Dfile=wls-maven-plugin.jar -DpomFile=pom.xml

Defining “pluginGroup” via global “settings.xml” file.

Step-3). Make sure to add the following “com.oracle.weblogic” in your “~/.m2/settings.xml” file:

<?xml version="1.0" encoding="UTF-8"?> 
<settings xmlns="http://maven.apache.org/settings/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> 

  <pluginGroups> 
    <pluginGroup>com.oracle.weblogic</pluginGroup>
  </pluginGroups>  
</settings>

Running the “mvn wls:help” command

Step-4). Once the “pluginGroup” is configured then from now on in this machine any time and from any directory we will be able to run the following wls maven task (For Example “mvn wls:help“):

$ cd /ANY/Directory/Of/Your/Choice
$ export M2_HOME=/PATH/TO/apache_maven_3.2.3
$ export JAVA_HOME=/PATH/TO/jdk1.8.0_60
$ export PATH=$JAVA_HOME/bin:/PATH/TO/apache_maven_3.2.3/bin:$PATH

$ mvn wls:help

Output of the above command should be something like following:

[INFO] Scanning for projects...
[INFO]

Creating a Simple WebApp and Deploy using plugin

Now we will go one step ahead and deploy a simple web application to WebLogic 12c using this plugin.

Step-5). Create a directory structure like following in anywhere your file system :

mkdir TestWLS_PluginProject
cd  TestWLS_PluginProject
mkdir -p src/main/webapp

Step-6). Now create a simple JSP “index.jsp” inside the “TestWLS_PluginProject/src/main/webapp” as following:

<HTML>
	<HEAD>
		<TITLE> Sample Web Application </TITLE>
	</HEAD>
	<BODY>
		<%
			out.println("
<h2>Hello World!!! , Date/Time: "+ new java.util.Date()+"
<h2>");
		%>
	</BODY>
</HTML>

Step-7). The most important part, Create the following kind of “TestWLS_PluginProject/pom.xml” file, Which will use the “wls-maven-plugin”. In the following pom.xml make sure to change the “CHANGE ME !!!” section with your own environment specific data.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  </properties>  
  
  
  <dependencies>
    <dependency>
      <groupId>javax</groupId>
      <artifactId>javaee-web-api</artifactId>
      <version>6.0</version>
      <scope>provided</scope>
    </dependency>
  </dependencies>
  
  <build>
   <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.3.2</version>
        <configuration>
          <source>1.7</source>
          <target>1.7</target>
        </configuration>
      </plugin>

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.1.1</version>
        <configuration>
          <failOnMissingWebXml>false</failOnMissingWebXml>
        </configuration>
      </plugin>
      
      <plugin>
        <groupId>com.oracle.weblogic</groupId> 
        <artifactId>wls-maven-plugin</artifactId> 
        <version>12.1.3.0</version> 
        <configuration> 
          <middlewareHome>${middleware.home}</middlewareHome>
          <adminurl>${admin.server.url}</adminurl>
          <user>${admin.username}</user>
          <password>${admin.password}</password>
          <name>${project.build.finalName}</name>
          <source>${project.build.directory}/${project.build.finalName}.${project.packaging}</source>          
        </configuration> 
      </plugin>
      
   </plugins>
  </build>
</project>

Step-8). Now build and deploy the application using the following command:

$ export M2_HOME=/PATH/TO/apache_maven_3.2.3
$ export JAVA_HOME=/PATH/TO/jdk1.8.0_60
$ export PATH=$JAVA_HOME/bin:/PATH/TO/apache_maven_3.2.3/bin:$PATH
cd  TestWLS_PluginProject

### To deploy application
mvn clean install wls:deploy

### To undeploy application
mvn wls:undeploy
