[EJB:010142] error for cascade-delete

Hi,

I'm getting [EJB:010142] error (Instance of EJB <relatedEJB> with primary key <pk> does not exist) while trying to implement a straight-forward cascade-delete option in ejb-jar.xml for a one-to-many relationship using EJB 2.1.

While the cascade-delete works well for a one-to-one relationship, it is throwing this error for one-to-many relationship.

DB used is Oracle 10g XE. Server is Weblogic 9.2 MP4.

Given below the exact error:

javax.ejb.EJBException: EJB Exception:: java.lang.IllegalArgumentException: [EJB:010142]Instance of EJB 'LineItem' with primary key 'li8' does not exist.

I have verified that the lineitem record that it is trying to delete is existing in the db table.

Please let me know what could be the possible issue.

Thanks,

any help on this would be appreciated
