[jboss-user] [JBoss jBPM] - Couldn't find process definition

Hi, while trying this code, im getting an exception. Does anyone know about this ? Thanks. Here is the code : GraphSession graphSession = jbpmContext.getGraphSession(); ProcessDefinition processDefinition = graphSession.findLatestProcessDefinition("Acces"); ProcessInstance processInstance = new ProcessInstance(processDefinition); Token t = processInstance.getRootToken(); t.signal(); Here is the trace : exception javax.servlet.ServletException: org.jbpm.JbpmException: couldn't find
