Question

I was using WebSphere Allication Server version 7.0.0.13 in deploying my application. The war was build using Ant version 1.8.2 to build the war and ear file. When I am installing my application through WebSphere, I hit the following error:

The EAR file could be corrupt and/or incomplete. Make sure that the
application is at a compatible Java(TM) Platform, Enterprise Edition
(Java EE) level for the current version of WebSphere(R) Application
Server.

com.ibm.websphere.management.application.client.AppDeploymentException
[Root exception is org.eclipse.jst.j2ee.commonarchivecore.internal.exception.DeploymentDescriptorLoadException:
dd_in_ear_load_EXC_]

May I know what cause the problem? Or did I miss configure something in Ant script? Below are the ANT script for compiling the WAR and EAR.

<target name="compilewar" description="generating war">
        <war destfile="${dist.path}/WebApp.war" webxml="${source.path}/mywebapp/src/main/webapp/WEB-INF/web.xml">
            <webinf dir="${source.path}/mywebapp/src/main/webapp/WEB-INF/" includes="**/*"/>
            <lib dir="${dist.path}/" includes="*.jar"/>
            <classes dir="${source.path}/mywebapp/src/main/resources/" includes="**/*"/>
            <fileset dir="${source.path}/mywebapp/src/main/webapp/">
                <include name="**/*.jsp"/>
            </fileset>
            <fileset dir="${source.path}/mywebapp/src/main/webapp/">
                <include name="main/**/*"/> 
            </fileset>
        </war>
    </target>

<target name="compileear" description="Compile Ear file">
        <ear destfile="${source.path}/myear/src/main/application/WebApp.ear" appxml="${svn.working.project.path}application.xml">
            <metainf dir="${source.path}/mywebapp/src/main/webapp/META-INF"/>
            <fileset dir="${dist.path}/" includes="*.war"/>
        </ear>
    </target>

THanks @!

I have the problem solved. This is due to the missing source properties in javac ant task. As mention in the ANT documentation for source properties:

Note that the default value depends on the JVM that is running Ant. We
highly recommend to always specify this attribute.

It is recommended to specify the java version that going to be used for the compilation. Below is the sample usage on the source properties:

<javac source="1.6"/>

THanks @!
