Hi Rahul,
The problem here is that the enhancer can't find persistence.xml in the
classpath. If you have persistence.xml defined in
E:\continuum-key-based-refactor\continuum-model\target\classes\META-INF,
it should be picked up.
Alternatively you can pass in the location of persistence.xml in with the -p
[path to persistence.xml] arguments. I think that just having
persistence.xml on the classpath would be easier and cleaner though, but
I've never looked into writing maven plugins..

Thanks Michael,
That helped a bit! What required config properties do I need to set? I
had the following set up in plugin config in the pom.xml.
[snip]
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>openjpa-maven-plugin</artifactId>
<version>0.0.1-SNAPSHOT</version>
<configuration>
<toolProperties>
<property>
<name>addDefaultConstructor</name>
<value>false</value>
</property>
<property>
<name>enforcePropertyRestrictions</name>
<value>true</value>
</property>
</toolProperties>
</configuration>
</plugin>

And this is what I see in the logs. Appreciate the help.
