Using EJB 1.1, CMP, and JAWS on jboss 3.2.1. I have a complex finder SQL as indicated in the trace below. Under some conditions a finder parameter could be null. When this happens, jBoss calls setNull(param, java.sql.NULL) instead of a more specific sql type like java.sql.VARCHAR. Unfortunately, DB2 can't handle it. Is there any way force the type to be passed in.

Thanks
