Calling concurrent program from OA Framework

I am sharing my coding experience while calling a concurrent program from OA Framework:

   OracleConnection pConncection = null;
   OraclePreparedStatement ptmst = null;
   OracleResultSet rs = null;
   OracleCallableStatement cstmt = null;

 /*
 ** Commented the below code as getting an error :: method getOADBTransaction() not found
 ** And tried with usual Oracle connection.
 */
 //OADBTransaction tx = (OADBTransaction)getOADBTransaction();
//java.sql.Connection pConncection = tx.getJdbcConnection();

 pConncection = (OracleConnection) TransactionScope.getConnection();
 ConcurrentRequest cr = new ConcurrentRequest(pConncection);
 String applnName = "APPLNAME"; //Application that contains the concurrent program
 String cpName = "CPNAME"; //Concurrent program name
 String cpDesc = "CPDESC"; // concurrent Program description

 Vector cpArgs = new Vector();

 cpArgs.addElement("TRANSACTIONNUM");
 cpArgs.addElement("");
 cpArgs.addElement(null);
 // etc... as per your requirement

// Calling the method here
cr.submitRequest(applnName, cpName, cpDesc, null, false, cpArgs);

------

               submitCPRequest(String arg1, String arg2, String arg3) throws Exception{

                OracleConnection con = null;
OracleCallableStatement cstmt = null;
StringBuffer qry = new StringBuffer();
int requestid = 0 ;

try
{
con = (OracleConnection)TransactionScope.getConnection();
qry.append("BEGIN");
qry.append(" YOUR_PKG.yourMethod(?,?,?,?);");
qry.append(" END;");
cstmt = (OracleCallableStatement)con.prepareCall(qry.toString());
// cstmt.setString(....... Process at your own ..

                }
                 catch(Exception e)
{
                //take care
                }
                finally {
                // take care
                }
               }
