[jboss-user] [JBoss jBPM] - Problem using jbpm server with fuzzy logic library

[jfrancoisl]

Hi, 
I am having problem with the jbpm server, more precisely, I am trying to implement certain calculations following a task activation in a jbpm workflow, and everything works fine until I initialise a class from the external library FuzzyJToolkit

I have no problem until I initialise an object from this class. If i create a local application with the same code and run it, everything executes fine... but when calling that function from the jbpm server i get the same problem every time.

Here is the error, in case it might help:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception
