[jboss-user] [JBoss jBPM] - ClassLoader problem

[peter77]

Hello,
 
I'm doing my first steps with jbpm and I have one problem.
With any example from jbpm-jpdl-3.2.3  package, which contain java class in project I have same exception.
This is exception from "websale" example:
 

java.lang.ClassNotFoundException
: class 'org.jbpm.websale.ShipItem' could not be found by the process classloader
