[JBoss-user] problem/mistake with CMP/CMR settings

[costin <gic...@ed...>]

  Hello!

  I am having difficulties with a CMR relation on one of my web-apps.

  I am using JBoss 3.2.0 and MySql 4.0.12 on Linux 2.4.18.

  I have the following diagram:

  +--------+
  | A bean |
  +--------+
      A 1
      |
      V *
  +------+
  |B bean|
  +------+

  The problem appears when creating the B bean. Using middlegen and
  xdoclet I have the following create method:

  ----

public java.lang.Integer ejbCreate(ALocal a ) throws javax.ejb.CreateException {
      // Set CMP fields
      // EJB 2.0 spec says return null for CMP ejbCreate methods.
      return null;
   }

   public void ejbPostCreate( java.lang.Integer id, , ALocal a ) throws javax.ejb.CreateException {
      // Set CMR fields
      setA(a);
   }
   ----

    So, basically I need a A reference before I can make some B beans.

    Typically, the A beans gets created first and then I have to add
    some B beans to the mix

    Even though , I am finding a reference to the
    ALocal (I am logging it and test it to be != null), after I make the call to the create() method
    the database field (I am using ForeingKeys) gets only NULL.

----
               try
                {
                        referenceA = getABean();
                        
                        if (referenceA== null)
                                logger.debug("*** reference A == null");
                        else
                                logger.debug("*** reference A NOT null");
                                
                        facade.create(
                                        referenceA
                        );

                        logger.debug("Done writing into the database");

                }
                catch (Exception e)
                {
                        logger.error("I have an exception");
                }

    Can anyone give me a clue here about what is going wrong...
