hello guys
what does it mean?


Tomcat throws this guy when I call my user.jsp page
I added OpenJPA and Persistence libraries
the error point to this code (Managed bean class)


please it worked on Glassfish before, but now throws this guy with Tomcat and also Glassfish too
please help me

I'm sure about libraries, persistence.xml and entity beans
It drives me crazy
