Weblogic 10.3 - web service - manual jdbc commit

Question

Hi All,
I need a little help.
I have been made a web service with a web method. My business logic is very strange, and I have to make some jdbc commit manually in the web method. I try to call transaction.begin() and transaction.commit() but the weblogic throws an exception:
javax.transaction.NotSupportedException: Another transaction is associated with this thread. Existing transaction Name=[EJB ...
Could you tell me, how can I get the current transaction context and handle manually the jdbc commit?
_Here is part of my code:_
@WebService()
@Stateless()
public class MyWebService
     * Web service operation
    @WebMethod(operationName = "businessDataUpload")
    public String businessDataUpload(@WebParam(name = "businessData") String businessData)
        try
            javax.naming.Context ctx = new javax.naming.InitialContext();
            javax.transaction.UserTransaction transaction =  (UserTransaction) ctx.lookup("javax.transaction.UserTransaction";);
            javax.sql.DataSource ds = (DataSource) ctx.lookup(JNDI_NAME);
            java.sql.Connection = ds.getConnection();
            *transaction.begin();*
            // jdbc code here
            transaction.commit();
catch (Exception ex)
// transaction rollback
transaction.rollback();
throw new RuntimeException(ex);
Please help me.
thx, SoMa

Hi SoMa,
Please try this:
@WebService()
@Stateless()
public class MyWebService
           * Web service operation
           @WebMethod(operationName = "businessDataUpload")
           public String businessDataUpload(@WebParam(name = "businessData") String businessData)
                                 try
                                            javax.naming.Context ctx = new javax.naming.InitialContext();
                                            javax.sql.DataSource ds = (DataSource) ctx.lookup(JNDI_NAME);
                                            java.sql.Connection con= ds.getConnection();
                                            con.setAutoCommit(false);                // By default on JDBC Connections the AutoCommit is TRUE  //
                                            // jdbc code here
                                            con.commit();
                                 catch (Exception ex)
                                            // transaction rollback
                                            con.rollback();
                                            throw new RuntimeException(ex);
                      }Thanks
