Hi, I got a javax.ejb.ObjectNotFoundException: exception trying to get a CMP Bean Data written by a MessageDrivenBean:
I am doing the following steps: MDB1 read some information from a topic MDB1 call the create method from a CMP Bean for saving the information in the DB MDB1 send a message to a queue with the primary key of the CMP Bean written before to the DB MDB2 read the primary key from the queue and starts a Thread parameterized with the primary key The Thread tries to get the CMP Bean data using the findByPrimaryKey method. I traced my Beans and I can recognize that the CMP Bean Data is on the DB ant the create method is finished. I suppose the problem is that the CMP.create transaction isn?t committed before I try to read the DB record using the CMP.findByPrimaryKey because it works if I insert a wait for 1000 ms and retry to execute the findByPrimaryKey method Now the question: How can I be sure that the create transaction is committed before I read it again? I am running Jboss 4.05, Oracle XE 10 and Java 1.4.2 all on the same server (ubuntu 2.6.15-26-server) here the completed exception: 19:40:38,778 ERROR [STDERR] javax.ejb.ObjectNotFoundException: No
