The stack shows that ClassGenerator class is present, while
ClassGeneratorResourceLoader is not. Both are coming from the same
JAR. Very strange... Could you possibly try the same thing with
Cayenne 3.0M5?
Also you can debug it with "ant -v" to see what the "full.classpath"
is set to (maybe there's a conflicting Velocity installation or
something).

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
