Calling OS390 DB2 stored proc expecting resultset

Has anybody been able to call a DB2 stored procedure on OS/390 with the JDBC adapter and received a resultset back? We have successfully called stored procs but so far those have just had input and output parameters (Call tab). I defined my desired fields in the Results tab but received an error when I tested it.

Never mind!! The tech who wrote the stored procedure did supply me with the correct list of parameters!!
