JPA - Weaving not enabled while running test cases

Question

I have an application that uses Eclipselink 2.5, and when running the Junit test cases, I always receive this warning:

[EL Warning]: metadata: 2013-08-19 01:14:05.142--ServerSession(14351551)--
Reverting the lazy setting on the OneToOne or ManyToOne attribute [currentTransit]
for the entity class [class ......persistent.entity.BPExecutionEntity] since
weaving was not enabled or did not occur.

So, I wrote a 'weaving' task on my Ant build file like this:

<target name="define.task" description="New task definition for EclipseLink static weaving">
    <taskdef name="weave" classname="org.eclipse.persistence.tools.weaving.jpa.StaticWeaveAntTask"/>
</target>
<target name="weaving" description="perform weaving" depends="define.task">
    <weave  source="D:\...\dist\${ant.project.name}.jar"
            target="D:\...\dist\woven-${ant.project.name}.jar"
            persistenceinfo="D:\...\lib\persistence.jar">
        <classpath>
        </classpath>
    </weave>
</target>

OK, everything works, and when I compile the code it generates a woven file half the size of the compiled jar. But, when I run the tests of the project then I still receive the same warning blah blah blah... since weaving was not enabled or did not occur.

Anybody knows how to remove this warning from my tests?

Answer 1

I finally solved the situation using dynamic weaving. As I'm using Netbeans 7.3.1, I went to the Project Options | Run | VM options and added this text: -javaagent:C:\eclipselink\jlib\eclipselink.jar, you can change the address to whatever address you have located the eclipselink.jar.

Then I added this line to the persistence.xml:

<property name="eclipselink.weaving" value="true"/>

That's all. This configuration enables dynamic weaving to execute test cases and removes the [EL Warning] Reverting the lazy setting on the OneToOne or ManyToOne attribute...etc.

You need to specify that static weaving is used in your persistence.xml properties. See http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Advanced_JPA_Development/Performance/Weaving/Static_Weaving
