[jboss-user] [jBPM Users] - Re: Problem to run jBPM under jBoss and searching for PVM do

[-Silver-]

Hi kukeltje, first of all thanks for the reply :)

1) I tried a clean jboss 5.1.0 AS and it starts without problems, then I installed jbpm and there are a lot of exception.
This is the first one:

I think that there's some problem with the mysql connection.
Mysql is correctly running on port 3306, what could cause this excepiton? Does JBoss search for connection libraries in a wrong path?
Doesn't JBoss have the correct privileges to access the database?
Anything else?
What could I do to solve?

2) I saw the documentation that you suggested, but I need documentation about the internal pvm's operation. For example, does it work like a state machine or like an Artificial Neural Network? etc.
