Hello, I'm trying to introduce a jBPM project successfully. We want to enable jBPM's persistence. The examples are intended to make a new connection to the database for jBPM. My application is using Hibernate already, and it creates the connection to the database. I can not accept two simultaneous connections, one of them just to jBPM. Ideally, jBPM reuses the existing connection.
Specifically is it enough with the object org.hibernate.Session order to jBPM realice its operations persistence?
I suppose that have a application with a database's connection and want to jBPM reuses the same connection, should be common. However, as the documentation and examples I see, they create new connection to jBPM. It makes me wonder if I'm wrong concepts and considering incorrectly the need to share the connection.
Can anyone give me any advice or warn me if I am engaged in a wrong way?
Thank you for your wisdom :)

[Beginner's Corner] - Jboss server startup issue (JNDI thread)

Hi All,
I have installed *Oracle 11gR2* as my database server on a *RHEL 6 machine*, and my *JBoss SOA suite 5.2* on another *RHEL 6* machine. I have checked that my *database is up and running and also its listener is up* and ready to listen. So the problem here is, whenever I try to startup my Jboss server it gets *stuck at +[NamingHelper] JNDI InitialContext properties:{}+* it waits on this thread for long time arund 30mins and then errors out with
Ora-12159 :TNS no appropriate service found.
I have checked everything from the *oracle side and all looks good* even the service name used to connect to the database is correct. So this is surely a JBoss side error I think. And hence need to know what exactly is the problem. Please help, for reference i have *attached the screen shot of my Jboss server startup error*. Thanks in advance.

It seems JBoss7.1 uses CXF by default.
Can anyone tell me how can I override CXF support by JBossWS-Native?
Thanks

Mauricio, as the book is developer's guide so I think it should be more from technical perspective. Mainly to illustrate:
- BAM - how to access history information (what was already executed even if the process instance is not finished yet).
- Tooling - dynamicity and versioning when using Guvnor/Designer and jBPM console
- Tooling - new features of designer - generate forms (maybe even form builder), service repository import
Does that sound suitable for the book?
Cheers

[jBPM] - jBPM as a webservice

I have seen some old discussions on this topic and looks like the best way to do this is to wrap it into a service and expose it ourselves. If anyone has written webservice that allows your users to
1.a) Start a stateful process
1.b) Add facts to a running stateful process
then I would like to know how you solved the following problem
2.a) Forwarding requests of type (1.b) to the server that is running that process (and not to some other server in the cluster)
One solution could be: To just add the request of type 1.b to database and have background jobs on each server in the cluster to poll database and see if there are any outstanding requests of type 1.b for only those processes that are running on that particular server.
I want to know of any solutions that are working for others.
