Subject Re: Enhancer problem, using ant

Michael -

When you define your openjpac task, you're missing some of the required
classes. You could change your 
openjpac taskdef to something like:

<taskdef
classpath="${jpa.lib}/openjpa-1.2.1.jar;${jpa.lib}/commons-lang-2.1.jar;commons-collections-3.2.jar"
name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask"> 
<classpath refid="cp"/>
</taskdef>
