Hello,
Thanks for your help, the error disappeared since we installed the WAS
5.0.2 fix pack. The WAS version we were previously using was 5.0.
Thanks & Regards,
Vikram Naik.

Subject: RE: Exception on invoking remove() on CMP EJB in WAS 5.
Hi,
Try to set cascadedelete flag for that bean in the deployment descriptor,
or, in the remove method for that bean iterate over related beans and call
remove method on their interfaces.
Hope this work, if not, sorry for the bad advise.
