JCA DB Adaptor to call a Stored Proc that updates a table

Question

Dear guru,
I've a created JCA Db adaptor that will be used by OSB 10.3.1 that ultimately will call a stored procedure to update a table. However, I encountered exception :
ORA-02089 COMMIT is not allowed in a subordinate session
CREATE or REPLACE PROCEDURE EXAMPLEA
StringA IN VARCHAR2,
AS
BEGIN
UPDATE TABLE_A
SET COLUMN_1 = 'testing'
WHERE STRINGA_COLUMN = StringA ;
COMMIT;
END;
If I removed the commit above, then I got another error :-
JCA-11811
Error while trying to prepare and execute an API.
An error occurred while preparing and executing the EXAMPLE_A. Cause: java.sql.SQLException: Unexpected exception while enlisting XAConnection java.sql.SQLException: Transaction rolled back: Transaction timed out after 31 seconds
Desperate help is needed. Thanks!

The stored procedure adapter service will execute within a JTA transaction that will be committed so you must not explicitly execute a commit as part of your procedure code. When setting up a connection-instance in weblogic-ra.xml, you must provide one of either xADataSourceName or dataSourceName, but not both. If you use xADataSourceName then make sure that the JTA XA Connection check box is checked when you create your database connection and specify a JNDI name. Uncheck the box if you use dataSourceName.
