The first runtime enhancement method is to provide a javaagent when launching the JVM that OpenJPA is going run in.

-javaagent:<openjpa_jar_location>

For Eclipse, specify the above javaagent value on the Run Configuration page.

For ANT, provide the javaagent value as a jvmarg when launching an application. Below is a snippet that shows how to pass in the javaagent when launching a Java SE application that uses OpenJPA.

    <path id="jpa.enhancement.classpath">
        <pathelement location="bin"/>
        <!-- lib contains all of the jars that came with the OpenJPA binary download -->
        <fileset dir="lib">
            <include name="**/*.jar"/>
        </fileset>
    </path>
    ...
    <target name="drive" depends="clean, build">
        <echo message="Running test with run time enhancement."/>
        <java classname="main.Driver" failonerror="true" fork="yes">
            <jvmarg value="-javaagent:${openJPA-jar}"/>
            <classpath refid="jpa.enhancement.classpath"/>
        </java>
    </target>
