I have a code snippet to call fireAllRules in order to trigger rule task to work. ================================================================== System.out.println("Before rule\n"); org.drools.runtime.StatefulKnowledgeSession ksession = (org.drools.runtime.StatefulKnowledgeSession) kcontext.getKnowledgeRuntime(); ksession.fireAllRules(); System.out.println("After rule\n"); =================================================================== and then I deployed all these artifacts to Guvnor repository by using Gnvnor plugin in eclipse. the I open a browser to http://localhost:8080/jbpm-console to start a process. i have been trying many ways to try to fire a rule task to work. however, It always stops at rule task and can not mve to next script task. I don't know why it goes this way. http://community.jboss.org/servlet/JiveServlet/downloadImage/2-631470-17156/450-88/Screenshot.png (http://community.jboss.org/servlet/JiveServlet/showImage/2-631470-17156/Screenshot.png) log file is attached. any suggest and help will be appreciated.
