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

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 javax.servlet.ServletException: Error calling action method of component with id taskform:transitionButton javax.faces.webapp.FacesServlet.service(FacesServlet.java:109) org.jbpm.webapp.filter.AuthenticationFilter.doFilter(AuthenticationFilter.java:56) org.jbpm.web.JbpmContextFilter.doFilter(JbpmContextFilter.java:83) org.jbpm.webapp.filter.LogFilter.doFilter(LogFilter.java:59) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) root cause javax.faces.FacesException: Error calling action method of component with id taskform:transitionButton org.apache.myfaces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:74) javax.faces.component.UICommand.broadcast(UICommand.java:106) javax.faces.component.UIViewRoot._broadcastForPhase(UIViewRoot.java:90) javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:164) org.apache.myfaces.lifecycle.LifecycleImpl.invokeApplication(LifecycleImpl.java:271) org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:86) javax.faces.webapp.FacesServlet.service(FacesServlet.java:94) org.jbpm.webapp.filter.AuthenticationFilter.doFilter(AuthenticationFilter.java:56) org.jbpm.web.JbpmContextFilter.doFilter(JbpmContextFilter.java:83) org.jbpm.webapp.filter.LogFilter.doFilter(LogFilter.java:59) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040127#...
