[jboss-user] [JBoss jBPM] - Re: How to start a deployed process from a jsp file?

Wed May 14 13:04:24 EDT 2008

Ok, thank you so far.
Now I created a new JSP file that looks like this:
<%@ page import="org.jbpm.*" %>
  | <%@ page import="org.jbpm.graph.def.*" %>
  | <%@ page import="org.jbpm.graph.exe.*" %>
  | <%@ page import="org.jbpm.db.GraphSession" %>
  | 
  | <%!
  | private void startProcessDefinition() {
  | 	String processDefinitionName = new String("websale");
  | 	JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
  | 	JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
  | 	try {
  | 		GraphSession graphSession = jbpmContext.getGraphSession();
  | 		ProcessDefinition definition = graphSession.findLatestProcessDefinition(processDefinitionName);
  | 		ProcessInstance instance = definition.createProcessInstance();
  | 		instance.signal();
  | 		jbpmContext.save(instance);
  | 	} finally {
  | 		jbpmContext.close();
  | 	}
  | }
  | %>
  | 
  | <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
  |     pageEncoding="ISO-8859-1"%>
  | <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
  | <html>
  | <head>
  | <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
  | <title>Insert title here</title>
  | </head>
  | <body>
  | <% startProcessDefinition();%>
  | </body>
  | </html>
But when I execute it I get this error:

Any idea why this error arise?
