Thear Jboss gurus. I have configured Jbuilder6 Enterprise - Jbos3.00beta using and open tool downloaded from www.protegra.com/javagroup.html. It is working ok. I made a EJB1.0 Entity Bean mapping a Oracle 8 Table and deploying it without problem nor error message. But when I test de Entity Bean creating instances, those are not inserting records in Oracle. The records are created in other unknown RDBMS (I suppose the default) because the RDBS response "..duplicate key.." when made intentional mistakes. Please help me.
