Hi all,

I am new to this hibernate entity manager thing.I am trying to use hibernate entity manager in J2SE environment.I am trying to create entity manager factory from my client program.While i am running the client it is showing the class def not found error i.e it is failing to find the
entity classes.The folder that contains the classes is also in the classpath.
I am unable to figure out why this error is occuring .Please help me in solving the issue.

Thank You.

your path seems to be wrong

see in line:
[java] Exception in thread "main" java.lang.NoClassDefFoundError: build/cla
sses/org/jboss/tutorial/entity/bean/Order (wrong name: org/jboss/tutorial/entity
/bean/Order)

verify your classpath for find the class org.jboss.tutorial.entity.bean.Order.

verifiy if you dir build/classes in the classe path.
