Hi,
I am enhancing my persistent classes at build time via ant. If I compile
the classes and then run the enhancer, it works fine. If I run the enhancer
again over classes that have already been enhanced, I get a
ClassNotFoundException on the first persistent class it tries. According to
the documentation, this should work. Does anyone have any ideas of what I am
doing wrong?
I am using OpenJPA 2.0.0.
The exception I get is:
[openjpac] java.lang.IllegalArgumentException:
java.lang.ClassNotFoundException: bean.system.User
