Problem to run jBPM under jBoss and searching for PVM docume

-silver- Dec 3, 2009 3:10 PM

Hi all and nice to meet you!
I'm new here but I think that I'll write many many posts!
I started work of my master thesis based on jBPM so I hope to find support here :) !

To start I've two questions:

1) I installed manually jBPM version 4.2 on jBoss 5.1.0GA then I went to folder "C:\jboss-5.1.0GA\bin\" and typed "run -c jbpm". I received the follow error message:

I know that I probably have a problem with my java path (I'm running java 32 under windows 7 64bit and something is wrong with path) could be this the problem?

2)Where could I find detailed PVM developer's documentation?

Thanks a lot!

Please try a clean JBoss AS server instance first before adding jBPM to it. Such an error has nothing to do with jBPM

2: What is detailed? Have you checked here: http://www.jboss.org/jbossjbpm/pvm/ And jBPM-JPDL itself is a great example of how to use the pvm

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.

Try adding the mysql driver jar manually to the classpath. This is missing in 4.2 (and there is a jira issue for it)

Oh, and about 2:

It's not an Artificial Neural Network, it's based on superposition and entanglement and touches on EPR

But on a more serious note, it is an advanced statemachine for process graphs.
