Created attachment 200475 [details]
My JPA project files

I tried to run a sample java 1.6 SE application from the Apress book Beginning Java EE 6 Platform with GlassFish 3 and got the following error. The  project has a Main class and an entity Book class. I used Eclipse Indigo to develop it. The database was Derby 10.8.2.1. (And EclipseLink JPA 2.3). The Java classes and the persistence.xml are in the attachment.

Thanks,
Chia
