the servlet code on jboss is

package cs;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class CustomerService extends HttpServlet
{

 public void doGet(HttpServletRequest rq,HttpServletResponse res)
 {


 ProcessDefinition pd =ProcessDefinition.parseXmlResource("processdefinition.xml" );

 ProcessInstance pi=new ProcessInstance(pd);
 PrintWriter pw;
 res.setContentType("text/html");
 try
 {
 pw = res.getWriter();
 pw.println("hello hw r u");
 pw.println("the 1 value is :-"+pd);
 pw.println("<br>the value is :-"+pi);
 pw.println("<br>---- :-"+pi.getRootToken().getNode().getName());

 Token t=pi.getRootToken();
 pw.println("<br>++++"+t.getNode().getName());
 t.signal();
 pw.println("<br>-----"+t.getNode().getName());
 t.signal();
 pw.println("<br>-----"+t.getNode().getName());
 }
 catch (IOException e)
 {
 e.printStackTrace();
 }


 }

}

the processdefinition.xml is

<?xml version="1.0" encoding="UTF-8"?>

<process-definition name="customerservice">
 <start-state name="customer calls">

 </start-state>


<state name="tt">

Soory the fine missing line of this issue is

Hi

for your knoweledge i have executed the same program on eclipse and its running perfect.
is is problem due to version of JBOSS JBPM server, because in console i get the warning that transtion to decision tag is resolved

what do you mean by

if i remove the tag and use tag the program runs fine

btw, the to="transfer" and to="what" point to non-eisting states. Isn't that your problem?
