Call Concurrent Program from OAF Page

I have seen many developers use fnd_request.submit_request to call the concurrent program from the OAF page, which is not only bad practice also makes controller code cumbersome.  Calling Concurrent request is very much simple , you just need to import the relevant classes and pass the program name and Parameters.

//Classes to be imported 
import oracle.apps.fnd.cp.request.ConcurrentRequest;
import oracle.apps.fnd.cp.request.RequestSubmissionException;




OADBTransaction tx=  am.getOADBTransaction();
       // Initialize the ConcurrentRequest Class
java.sql.Connection con = tx.getJdbcConnection();

 ConcurrentRequest requestObject = new ConcurrentRequest(con);

     //Application Short name under which the calling concurrent program is registered
  String applShortName = "XX";

     // Calling Concurrent program Short name
    String cpName = "XXCONCSHORTNAME";
      // Calling Concurrent program Description   

       String cpDesc = "Program call through OAF";
       Vector vector = new Vector();
       vector.addElement(String.valueOf(OrderId));
       vector.addElement(String.valueOf(OrderType));                 
       vector.addElement(String.valueOf("N"));
       
         // Concurrent Program submission
         int requestId=0;
                try {
                    requestId =
    requestObject.submitRequest(applShortName, cpName, cpDesc, null, false, vector);
                } 
catch (RequestSubmissionException e)
          {
                    // TODO
                     throw new OAException("Concurrent error--"+e,  OAException.ERROR);
                }
                tx.commit();
   
       System.out.println("e requestId--"+ requestId);
     throw new OAException("Concurrent Program submitted succesfully " and Concurrent       Request id is--"+requestId,  OAException.INFORMATION);

   }
