    order by problem

    ongtw Newbie

      hi all,

      i tried playing around with this order by thingy that you've been talking about here but to no avail. what i did is similar to the following:

      in my ejb:
      * @ejb.interface-method
      * @
      public abstract java.util.Collection ejbSelectGeneric(String jbossQL, Object[] args)
      throws javax.ejb.FinderException;

      * @ejb:home-method
      * tview-type="local"
      public java.util.Collection ejbHomeOrdersByCusid(java.lang.Integer cusid, java.lang.Integer filter, java.lang.String sortby)
      throws javax.ejb.FinderException{
      // generate JBossQL query
      StringBuffer DynamicQl = new StringBuffer();
      DynamicQl.append("SELECT OBJECT(g) ");
      DynamicQl.append("FROM Job g ");
      DynamicQl.append("WHERE g.cus_no = ?1 AND g.status = ?2");
      DynamicQl.append(" ORDER BY g.");


      // pack arguments into an Object[]
      Object[] args = new Object[2];
      args[0]= cusid;
      args[1]= filter;
      //args[2]= sortby;

      Debug.print("args[1]:"+args[1]); return ejbSelectGeneric(DynamicQl.toString(), args);

      in my session bean i have this:

      * @ejb.interface-method
      * tview-type="remote"
      public java.util.Collection getAllOrders(java.lang.Integer cusid, java.lang.Integer filter, java.lang.String sortby){
      Debug.print("Entering getAllOrders");
      JobHome = JobUtil.getLocalHome();
      Job = JobHome.ordersByCusid(cusid,filter,sortby);
      Debug.print("Leaving getAllOrders");
      }catch(NamingException name){
      Debug.print("ProcessOrder: userExists: NamingException occured in JobUtil.getLocalHome()");
      return null;
      }catch(javax.ejb.FinderException name2){
      Debug.print("ProcessOrder: cannot locate method");
      return null;
      return Job;

      I did add the following to the xml file as stated:


      now the problem is whenever it is calling this ejbSelect method, it returns a finderexception. it cannot locate the method. can anyone help me?

          i found the errors and am able to use it now.

          however when i tried to get the data out from the collection that it returns, it gave me the following errors:

          at org.jboss.ejb.plugins.local.EntityProxy.invoke(EntityProxy.java:38)
          at $Proxy2.setCloseby(Unknown Source)
          at sg.com.studiotech.test.ProcessOrderTest.testBean(ProcessOrderTest.java:63)
          at sg.com.studiotech.test.ProcessOrderTest.main(ProcessOrderTest.java:83)
          Exception in thread "main"

          this error occurs when i tried to use the get method to get the data from this object. Does anyone know why this is happening?

          Any help will be appreciated.

            Where is your client, is it in the same JVM or is it remote?
