Coding for Stored Procedures is a lot of work!

Question

Will simple Stored Procedure calls be made any easier in TopLink? Below is the JDBC code for calling a stored procedure. Following it is the lengthy TopLink code for calling the same proc.
JDBC:
CallableStatement stmt = conn.prepareCall("{CALL JEROME_TEST.EMP_SELECT(?,?,?)}");
stmt.setInt(1, 7369);
stmt.registerOutParameter(2, Types.VARCHAR);
stmt.setString(2, "Get");
stmt.registerOutParameter(3, Types.VARCHAR);
stmt.execute();
System.out.println("job = " + stmt.getString(2));
System.out.println("name = " + stmt.getString(3));TopLink
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("JEROME_TEST.EMP_SELECT");
call.addUnamedArgument("empno");
call.addUnamedInOutputArgument("job", "job", String.class);
call.addUnamedOutputArgument("name");
DataModifyQuery query = new DataModifyQuery();
query.setCall(call);
query.addArgument("empno");
query.addArgument("job");
query.addArgument("name");
m_session.addQuery("JEROME_TEST.EMP_SELECT", query);
m_session.getEventManager().addListener(
        new SessionEventAdapter() {
            public void outputParametersDetected(SessionEvent event) {
                if (((StoredProcedureCall)event.getProperty("call")).
                    getProcedureName().equals("JEROME_TEST.EMP_SELECT")){
                    DatabaseRow row = (DatabaseRow)event.getResult();
                    Object returnJob = row.get("job");
                    Object returnName = row.get("name");
                    System.out.println("job = " + returnJob);
                    System.out.println("name = " + returnName);
Vector parameters = new Vector();
parameters.addElement(new java.lang.Integer(7369));
parameters.addElement("Get");
parameters.addElement("");
Object data = m_session.executeQuery(query, parameters);

Answer 1

Much of the code you have defined is for being able to reuse the call. If you just want to execute it you can use:
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("JEROME_TEST.EMP_SELECT");
call.addUnamedArgumentValue(new Integer(7369));
call.addUnamedInOutputArgumentValue("job", "Get", String.class);
call.addUnamedOutputArgument("name");
Map row = (Map) session.executeSelectingCall(call).first();
System.out.println("job = " + row.get("job"));
System.out.println("name = " + row.get("name"));
