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:
