Hi,

Can anybody help me resolving the following error?



I removed some line of error message stack as it is too big to put here.

My hibernate mapping file :-


where project manager is a foreign key in ART_ProjectTab table and primary key in ART_EmployeeTab table.

When I try to add the project details to DB i am getting the following error. I tried in web also but didn't get enough information to resolve the issue.

Thanks,
Vighnesh

Can you paste the source code for the two java classes as well ( ART_ProjectVO and ART_EmployeeVO).

What I don't understand is how they changed the earth's orbit to fit the metric calendar. Tiny ad:
