Hi,
I'm currently experimenting with cayenne; it's looking good.
I have however run into problems while running the ant cgen task. I'm
not sure what's going wrong with ant cgen. I would be grateful for any
help on this. Please see my ant task below:
<path id="full.classpath">
<fileset dir="lib" />
</path>
<!-- Custom apache cayenne ant tasks...-->
<typedef resource="org/apache/cayenne/tools/antlib.xml">
<classpath refid="full.classpath"/>
</typedef>
<target name="classgen">
<cgen map="src/PersistenceMap.map.xml" destDir="test"
usepkgpath="true" superpkg="com.plugin.persistence" />
</target>
and inside my lib directory I have the cayenne.jar file
When I now run ant classgen, I get the following error:
sysad...@astrodon$ ant classgen
Buildfile: build.xml
classgen:

What could be going wrong?
Thanks,
