[Persistence, JBoss/CMP, Hibernate, Database] - Generate XML from an entity
by poyge394
Hi,
In my application i generate an xml file from entity beans,
before i run
manger.persist(entity);
my generated xml looks like:
| <rollingstock>
| <rollingstockId>0</rollingstockId>

| <storedSnapshot class="list">

| </storedSnapshot>
| </vehicles>
| </rollingstock>
|
|
as you see hibernate add hibernate specific information to the POJO as:
| <initialized>true</initialized>
| <cachedSize>-1</cachedSize>
| <dirty>false</dirty>
| <storedSnapshot class="list">
| <vehicle reference="../../bag/vehicle"/>
| </storedSnapshot>
|
is it possible to get an xml as it look like before the manager.persist call.

[Installation, Configuration & Deployment] - Re: Transaction changes foiled me
by camunda
Any ideas to that issue? I encountered the same problem, I have a JTA environment with jbpm 3.2 (works with Hibernate) calling in a action a EJB 3 SessionBean with creates a EJB 3 Entity Bean.
I am not sure whats the problem, the second transaction should just join the first one. The log says:

[JBoss jBPM] - Re: multiple jobexecutor threads?
by estaub
Alex,
If you search for "StaleObjectStateException", you'll see other instances on this forum where it occurs after a fork. I don't know if it has the same cause as yours, because you didn't report any details about what you're doing. Unfortunately, no one bothered to follow up with a resolution or workaround, if one was found.
Also, see http://jira.jboss.com/jira/browse/JBPM-626. I'm not sure if it's relevant. It's reported in enough detail that you can probably tell. But again, unfortunately, no resolution or workaround was reported, if found.
I suggest that you prove to yourself that when your async events kick off, you're picking up the different node instances - not accidentally grabbing the same node instance, somehow.
Beyond that, sorry, I got nuthin'.
Please report what you find - this will be my problem soon, too!
-Ed Staub
