thank you,but I use the bpmn file ,in JBPM4.4 it is simple to achieve this function:

<%@page import="org.jbpm.api.*,java.io.*"%>
<%
 ProcessEngine processEngine = Configuration.getProcessEngine();
 RepositoryService repositoryService = processEngine
   .getRepositoryService();
 ExecutionService executionService = processEngine
   .getExecutionService();
 String id = request.getParameter("id");
 ProcessInstance processInstance = executionService
   .findProcessInstanceById(id);
 String processDefinitionId = processInstance
   .getProcessDefinitionId();
 ProcessDefinition processDefinition = repositoryService
   .createProcessDefinitionQuery().processDefinitionId(
     processDefinitionId).uniqueResult();
 InputStream inputStream = repositoryService.getResourceAsStream(processDefinition.getDeploymentId(),"loan.png");
 byte[] b = new byte[1024];
 int len = -1;
 while ((len = inputStream.read(b, 0, 1024)) != -1) {
  response.getOutputStream().write(b, 0, len);
 }
%>

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@page import="org.jbpm.api.*,java.util.*,org.jbpm.api.model.*" %>
<%
 String id = request.getParameter("id");
 ProcessEngine processEngine = Configuration.getProcessEngine();
 RepositoryService repositoryService = processEngine.getRepositoryService();
 ExecutionService executionService = processEngine.getExecutionService();
 ProcessInstance processInstance = executionService.findProcessInstanceById(id);
 Set<String> activityNames = processInstance.findActiveActivityNames();
 
 ActivityCoordinates ac = repositoryService.getActivityCoordinates(processInstance.getProcessDefinitionId(),activityNames.iterator().next());
%>
