OK, I am trying this, but neither the @weblogic.dbms-column-type or the @weblogic.transaction-isolation have a parameter identified. What am I suppose to use as ???="TRANSACTION_READ_COMMITTED_FOR_UPDATE"?

Note to get blob/clobs to work properly I had to set the transaction isolation to TRANSACTION_READ_COMMITTED_FOR_UPDATE for the specific bean. Look at the docs surround the @weblogic.transaction-isolation tag. -- Mike On Jul 20, 2004, at 5:00 PM, [EMAIL PROTECTED] wrote: > Does anyone know how I am going to set this up in XDoclet? > >> -----Original Message----- >> From: Horvath, Tibor >> Sent: Tuesday, July 20, 2004 4:45 PM >> To: Horvath, Tibor; Knutson, Mick >> Subject: RE: http://e-docs.bea.com/wls/docs61/ejb/cmp.html#1061636 >> >> >> >> -----Original Message----- >> From: Horvath, Tibor >> Sent: Tuesday, July 20, 2004 3:02 PM >> To: Knutson, Mick >> Subject: http://e-docs.bea.com/wls/docs61/ejb/cmp.html#1061636 >> >> BLOB and CLOB DBMS Column Support for the Oracle DBMS >> >> WebLogic Server supports Oracle Binary Large Object (BLOB) and >> Character >> Large Object (CLOB) DBMS columns with EJB CMP.
