How to Use SOAP with osworkflow---client test2

[Shantanu Puranik]

Dear all:
I download osworkflow2.8 and deploy osworkflow-2.8.0-example
(my environment: JDK1.5+Tomcat5.5+MSSQL2005)

I can use soap to create a new workflow entry like this:newworkflow.jsp
========================================================
<%@ page import="com.opensymphony.workflow.Workflow"%>
<%@ page import="com.opensymphony.workflow.basic.BasicWorkflow"%>
<%@ page import="org.codehaus.xfire.client.XFireProxyFactory"%>
<%@ page import="org.codehaus.xfire.service.Service"%>
<%@ page import="org.codehaus.xfire.service.binding.ObjectServiceFactory"%>

<%
        String serviceURL = "http://localhost:8080/osworkflow/soap/Workflow";
        Service serviceModel = new ObjectServiceFactory().create(Workflow.class);
        XFireProxyFactory serviceFactory = new XFireProxyFactory();
       
        Workflow wf = (Workflow) serviceFactory.create(serviceModel, serviceURL);
    //Workflow wf = new BasicWorkflow((String) session.getAttribute("username"));
        long id = wf.initialize("example", 100, null);
%>

New workflow entry <a href="test.jsp?id=<%=id%>">#<%=id%></a> created and initialized!

<%@ include file="nav.jsp" %>
==========================================================
but when i try to do other things like:test.jsp
===========================================================
<%
.......
    Long id = Long.parseLong(request.getParameter("id"));

    String doString = request.getParameter("do");
    if (doString != null && !doString.equals("")) {
        int action = Integer.parseInt(doString);
        wf .doAction(id, action, Collections.EMPTY_MAP);
    }

    int[] actions = wf.getAvailableActions(id, null);
    WorkflowDescriptor wd =  wf.getWorkflowDescriptor(wf.getWorkflowName(id));
       
        for (int i = 0; i < actions.length; i++) {
        String name = wd.getAction(actions[i]).getName();
        %>
        <li> <a href="test.jsp?id=<%=id%>&do=<%= actions[i] %>"><%= name %></a>
        <%
    }
   
%>
......
=========================================================
i got error message:

exception

org.apache.jasper.JasperException: Exception in JSP: /test.jsp:33

30:     }
31:
32:     int[] actions = wf.getAvailableActions(id, null);
33:     WorkflowDescriptor wd =  wf.getWorkflowDescriptor(wf.getWorkflowName(id));
34:
35: for (int i = 0; i < actions.length; i++) {
36:         String name = wd.getAction(actions[i]).getName();

why i can't get WorkflowDescriptor???
(WorkflowDescriptor wd =  wf.getWorkflowDescriptor(wf.getWorkflowName(id));)

i also can't use workflow.query() like underway.jsp
======================================================
....
List workflows = (List) wf.query(query);
.....
======================================================

the example can run without error if i use basicworkflow:
Workflow wf = new BasicWorkflow((String) session.getAttribute("username"));


Please kindly help me and excuse my poor English >""""<
Thank a lot!!
