[jboss-user] [JBoss jBPM] - While starting process from a servlet error arise

[coolex]

Hi!

I created a servlet to start the standard jbpm process "websale". I simply deployed it to the server. This is the code:

  | import java.io.IOException;
  | 
  | import javax.servlet.ServletException;
  | import javax.servlet.http.HttpServletRequest;
  | import javax.servlet.http.HttpServletResponse;
  | 
  | import org.jbpm.graph.def.ProcessDefinition;
  | import org.jbpm.JbpmConfiguration;
  | import org.jbpm.JbpmContext;
  | import org.jbpm.db.GraphSession;
  | import org.jbpm.graph.exe.ProcessInstance;
  | 
  | public class HelloWorld extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
  |    static final long serialVersionUID = 1L;
  |    
  |  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();
  | 	}
  |  }
  |    
  | 	public HelloWorld() {
  | 		super();
  | 	}   	 	
  | 	
  | 	protected void doGet(	HttpServletRequest request, 
  | 							HttpServletResponse response) 
  | 	throws ServletException, IOException {
  | 		startProcessDefinition();
  | 	}   	  	    
  | }
But when I execute it the following error comes up:
anonymous wrote : org.jbpm.JbpmException: couldn't find process definition 'websale'
  | 	org.jbpm.db.GraphSession.findLatestProcessDefinition(GraphSession.java:170)
  | 	HelloWorld.startProcessDefinition(HelloWorld.java:24)
  | 	HelloWorld.doGet(HelloWorld.java:43)
  | 	javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
  | 	javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
  | 	org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
The process is deployed and works fine.
I tried to configure the hibernate.cfg.xml (located in the WebContent directory) file and also tried to find some help in the docu. 
Hope you can help me.

Bye
