--------------------------------------------------------------
During the development meeting in Brno in November, I was told that the bean instance pools were specific to each bean. For example, if you had two stateless session beans, let's just call them Bean A, and Bean B, you could define a strict max instance pool for each one. For the life of me I don't see how you can actually do this with the current schema.
There is nothing in the schema to associate a bean, by name or any other attribute, to a pool.
Is there a way to do this?
How does this really work? It appears that there is really just one pool, and everything shares it, even if there are multiple deployments.

Hello,
I have some questions based on my understanding, please correct me if I am wrong, If I am right please guide me through my questions...thanks in advance...
h3. My Understanding:
task (taskid, session id) is belongs to process (process id , session id), task no longer valid without process reference (I am talking about persistence in JBPM)
h3. My questions?
1. Do we really need separate persistence.xml file for each humantask persistence and process persistence?
2. Why there is a two types of transaction used in this persistence (like JTA-process, resource local for - task)?
3. Is it possible to create one persistence.xml file to handle JBPM persistence (both process and humantask)?
4. Do I need two schema (one for process table and one for task tables)?
kindly invite you all to participate in this discussion...
thanks,

[jBPM] - jBPM Designer won't save when validation fails

"jBPM Designer won't save when validation fails"

--------------------------------------------------------------
I was using the 2.4-Final release of the jBPM Designer, doing high level design and saving my work periodically, and all of a suddent a message appears saying "Unable to perform user action due to errors. Validate your process before saving...". Then it locked up and I lost my work. Does a process need to pass validation to save? This seems unreasonable if I'm just trying to lay out high level design. Here is the stack trace I got when it locked up:
16:23:38,417 ERROR [org.jbpm.designer.web.profile.impl.JbpmProfileImpl] (http-localhost-127.0.0.1-8080-26) null: java.lang.NullPointerException

[JBoss Cache] - Unable to connect to JGroups channel

"Unable to connect to JGroups channel"

--------------------------------------------------------------
Hi all!
I manage a cluster with two servers and four nodes. Each server has two instances of JBoss EAP 5.
Everything were goin on, but suddenly two nodes on the same server lost connection to JGroups and now they do not connect more.
I've already checked the MultiCast UDP with McastSenderTest and McastReceiverTest programs and MultiCast UDP works.
If I change the UDP address and port and start the problematic instances, JGroups works but with the UDP addres of the other server instances the problem back.
Thanks in advance!
Sorry for the english mistakes.
This is the stack trace of the exception.
