print process classloader
I'm building a program that runs a workflow. In my workflow, i've defined an action inside an event. But, when the action is triggered, i get the exception:
17:39:44,676 ERROR [Delegation] couldn't load delegation class 'com.sample.jbpm.action.SendMailHandler' java.lang.ClassNotFoundException: class 'com.sample.jbpm.action.SendMailHandler' could not be found by the process classloader at org.jbpm.instantiation.ProcessClassLoader.findClass(ProcessClassLoader.java:39) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.jbpm.instantiation.Delegation.instantiate(Delegation.java:105) at org.jbpm.instantiation.Delegation.getInstance(Delegation.java:90) at org.jbpm.graph.def.Action.execute(Action.java:78) at org.jbpm.graph.def.GraphElement.executeActions(GraphElement.java:186) at org.jbpm.graph.def.GraphElement.fireAndPropagateEvent(GraphElement.java:149) at org.jbpm.graph.def.GraphElement.fireEvent(GraphElement.java:133) at org.jbpm.graph.def.Node.leave(Node.java:337) at org.jbpm.graph.node.TaskNode.leave(TaskNode.java:167) at org.jbpm.graph.exe.Token.signal(Token.java:127) at org.jbpm.graph.exe.Token.signal(Token.java:92) at com.sample.jbpm.WorkFlow.nextTaskNode(WorkFlow.java:159) at com.sample.jbpm.WorkFlow.start(WorkFlow.java:112) at com.sample.jbpm.WorkFlow.doGet(WorkFlow.java:85) at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.CustomPrincipalValve.invoke(CustomPrincipalValve.java:39) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:159) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:59) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:856) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:744) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Thread.java:595)
