Nothing strikes me as being incorrect about your persistence.xml or  
orm.xml. Are these files available in the META-INF/ directory at the  
root of one of your classpaths? How are you running the enhancer?

If you can run it with verbose logging (e.g., by setting the property  
"openjpa.Log: DefaultLevel=TRACE"), can you send us the output, as  
well as the exact setting of your CLASSPATH environment variable and  
the location of your persistence.xml and orm.xml files?

We don't have any support for declaring that an object be read-only.  
Can you describe more in-depth the scenario in which you need to have  
instances be marked read-only (as opposed to being just de-facto read- 
only by way of just never making changes to the instances)?
