I post my simple project and jar file here.

I have the following problem with the project: while running the client I got the following error:

java.lang.reflect.UndeclaredThrowableException

After several weeks of finding out errors, I do not know if the error is in my implemention of the bean or it is in mapping file.

Please help me to find out the error!!!

Every comments are welcolme.

Regards.

I got it, it is my fault. The implementation was not correct, it returned a colletion of local interfaces. The mapping is right.

Thanks for your help.
