Hi guys,
I´ve the following problem with the variables types in JBPM 4.4: When we store a large String as process variables, we get a hibernate exception during the saving. As far as I can see, the String is simply too large for the target column. It´s defined as VARCHAR2(255).
We currently use a serializable container object to store only one String value in it. That way it´s put in the JBPM_LOB table, everything is fine. Am I missing something? Is there a better way to deal with it?
If not, we will be forced to always use container objects as the content of variables is dynamic and can be of arbitrary size.
Btw, we use the same trick to deal with Hibernate objects. We have unsaved Hibernate objects we want to pass along as process variables. Seems trivial, but doesn´t work, because jbpm tries to save only the it´s id as a reference to this object (leading to an exception in our case). That´s annoying and we´re also using a container object here. Again, it works but doesn´t feel good.
Fiddling around with the types.xml would feel even worse ;-) Any options?
Cheers,
Charles

It's not impossible that my MDB config is wrong, it's bothering that same configuration works consistently in weblogic and websphere but not in jboss. As I said, I did try to make the subscription durable, see the MDB's ejb-jar.xml underneath.
I also tried to make the messages persistent, but at that point the text in the system.out became "+10:10:38,736 INFO [STDOUT] Warning: Message to JBossTopic[com.bluemartini.DBUt++ilTopic] not processed: delegator->JBossMessage[5244570167312385]:++*PERSISTENT*++, de++liveryId=1+", and the JMS message was still delivered 2 times out of 3.
Frankly there is a certain hint of flakiness coming out of this issue, in regards to JBoss capability of working with JMS. Hope I'm wrong and indeed something in our app is interfering with the JMS (although don't really see how...)
thanks/Ranjix
P.S. Again, a hint towards where in the sources is the text "Message to JBossTopic" constructed would really help. At that point I could try and debug.

the problem comes from join3 / fork3.
Any idea why this doesn't work ?
Thanks in advance,
