EJBQL with boolean field on Oracle

Question

Hi
I am using the following query to find the default group of a customer where defaultGroup
is a boolean field.
SELECT DISTINCT OBJECT(g) FROM ServiceGroup g WHERE g.defaultGroup AND g.customer
= ?1
When I call this query I get the following error
javax.ejb.EJBException: nested exception is: javax.ejb.TransactionRolledbackLocalException:
EJB Exception: ; nested exception is: javax.ejb.EJBException: Problem in findCustomerDefault
while preparing or executing statement: 'weblogic.jdbc.rmi.SerialPreparedStatement@e0bfd':
java.sql.SQLException: ORA-00920: invalid relational operator
I believe this has something to do with the fact that booleans are represented
as numbers in Oracle as it works fine with another DB that supports boolean types.
And when I run the following query in sql+ "select * from servicegroup where
customer=1 and default_group" I get the same error. The getters and setters work
fine it is just when it is used in a query. Anybody know of a way to fix this
without having to change the CMP field to an int and put a boolean wrapper around
it?

Unfortunately, not using cursors is not an option for me. The DBA I talked to indicated to me that the only way to get a result set from a stored procedure in Oracle is to use a cursor. It doesn't really matter if that is correct or not, as all our stored procedures for Oracle are written assuming that is true. Here is the code for the stored procedure that uses a cursor:
create or replace procedure DI0002
(P_USER IN types.char32,
P_CURSOR IN OUT types.GenCursor)
IS
BEGIN
   OPEN P_CURSOR FOR
SELECT * FROM DITEST
WHERE MBR_NAME = P_USER;
END;types.GenCursor is a ref cursor, types.char32 is a 32 byte character value.
Also, your suggestion doesn't address the problem I'm having with getUpdateCount always returning a -1.
