How would this caller sometimes pass 'my-func.notRequired' and other times
not? As soon as you create <param>, the property is defined for the callee.

Example:
<target name="ejbdoclet" depends="">
<!-- check parameters -->
<fail unless="metainf" message="no 'metainf' parameter"/>
<fail unless="gen.src" message="no 'gen.src' parameter"/>
<fail unless="merge.dir" message="no 'merge.dir' parameter"/>
<fail unless="ejb.spec" message="no 'ejb.spec' parameter"/>
<fail unless="src" message="no 'src' parameter"/>
<fail unless="includes" message="no 'includes' parameter"/>
<fail unless="excludes" message="no 'excludes' parameter"/>
<!-- create output directories -->
<mkdir dir="${gen.src}"/>
<mkdir dir="${metainf}"/>
<ejbdoclet destdir="${gen.src}" mergedir="${merge.dir}"
ejbspec="${ejb.spec}" verbose="true">
<fileset dir="${src}" includes="${includes}"/>
<packageSubstitution packages="ejb" substituteWith="interfaces"/>
<remoteinterface/>
<localinterface/>
<homeinterface />
<localhomeinterface/>
<dataobject/>
<valueobject/>
<entitypk/>
<entitycmp/>
<entitybmp/>
<session/>
<dao>
<packageSubstitution packages="ejb" substituteWith="dao"/>
</dao>
<utilobject includeGUID="true"/>
<deploymentdescriptor destdir="${metainf}" validatexml="true"/>
<jboss version="${jboss.version}" xmlencoding="UTF-8"
destdir="${metainf}" validatexml="true"
datasource="${datasource}"
datasourcemapping="${datasourcemapping}"/>
</ejbdoclet>
</target>
I really would rather not rape-and-paste this task for each of my 4
different EJB jar files. I also do not want to expend the time running each
subtask if none of the *Bean files have changed...
Thanks,
Michael
