Using 2 versions of JAVA_HOME through one build script

[Sr...@timeinc.com]

 

I have the following build.xml file for doing the build. I need to
switch my java_home every time to do two versions of weblogic builds.
Instead of setting through system control panel JAVA_HOME , I want to
set it through ant script.

 

 

<project name="ejblink" default="all" basedir=".">

  <!-- set global properties for this build -->

  

    <property name="source" value="."/>

  <property name="build" value="${source}/build"/>

  <property name="dist" value="${source}/dist"/>

  <property name="ejbc_jar_file" value="OMSQueueEngine.jar" />

  <property name="war_file" value="OMSQueueEngine.war" />

  <property name="ear_file" value="OMSQueueEngine.ear" />

    <property name="ANT_HOME" value="C:\apache-ant-1.6.2" />

 

<path id="base.path">    

    <fileset dir="${ANT_HOME}/lib">

        <include name="**/*.jar"/>

    </fileset>

  </path>

 

<echo message="${ANT_HOME}" />

 

<path id="classpath.server">

     <path refid="base.path"/>

               <pathelement location="lib/weblogic.jar"/>

        <pathelement location="lib/webservices.jar"/>

        <pathelement location="lib/xerces.jar"/>

        <pathelement location="lib/ejbgen.jar"/>

    </path>

 

 

<taskdef name="wlappc" classname="weblogic.ant.taskdefs.j2ee.Appc"
classpathref="classpath.server" />

 

<taskdef name="servicegen"
classname="weblogic.ant.taskdefs.webservices.servicegen.ServiceGenTask"
classpathref="classpath.server" />

 

 

  <target name="all" depends="clean, ear"/>

 

  <target name="clean">

    <delete dir="ejbcgen" />

    <delete dir="${build}" />

    <delete dir="${dist}" />

    <delete file="${war_file}"/>

    <delete file="dist/${ear_file}"/>

   

  </target>

 

  <target name="ear" depends="build-ejb">

       <delete dir="${build}" />

    <mkdir dir="${build}" />

    <copy todir="${build}" file="${dist}/${ejbc_jar_file}"/> 

    

    

    <servicegen

      destEar="dist/${ear_file}"

      warName="${war_file}" 

      contextURI="OMS">

                  <service

            ejbJar="${build}/${ejbc_jar_file}"

            targetNamespace="http://localhost:7011/OMS/OMSQueueEngine"

            serviceName="OMSQueueEngine"

            serviceURI="/OMSQueueEngine"

            generateTypes="True"

            expandMethods="True" >

        </service>

             <classpath refid="classpath.server"/>

           </servicegen>

  </target>

 

  <target name="build-ejb">

<delete dir="${build}" />

    <delete dir="${dist}" />

    <mkdir dir="${build}" />

    <mkdir dir="${dist}"/>

    <javac source="1.5" srcdir="src" excludes="Client.java"
destdir="${build}">   

     <classpath refid="classpath.server"/>

   

   </javac>

    <copy todir="${build}/META-INF" >

      <fileset dir="." >

        <include name="*.xml"/>

      </fileset>

    </copy>

    <jar jarfile="${dist}/${ejbc_jar_file}"

         basedir="${build}"

         update="yes"/>

    <wlappc debug="${debug}"

      source="${dist}/${ejbc_jar_file}"

      />

 

 

 </target>

</project>

I'm afraid you can't, unless the tasks you use support setting it in
some way.  The only way I'd see is using <exec> (which allows
re-setting environment variables) instead of the custom tasks.
