jbpm---example

这些都被传智播客封装了的例子。。我只是抄下来而已

使用：
deployProcessDefinition.jsp

JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();
DiskFileUpload fileUpload = new DiskFileUpload();
List list  = fileUpload.parseRequest(request);
Iterator iterator = list.iterator();
FileItem  fileItem = (FileItem)iterator.next();

if(fileItem.getContentType().indexOf("application/x-zip-compressed") == -1){
  throw new Exception("Only zip format is accepted!");
}

try{
  WorkflowEngine workflowEngine = ServiceLocator.getWorkflowEngine()
  String pdname = workflowEngine.deployProcessDefinition(fileItem.getInputStream(),null);
  out.println("流程定义部署成功:"+pdname);

}catch(Exception e){
   
}

jbpmContext.close();

saveQingjiaForm.jsp //注意，先填写请假表单，然后就到这个页面
//这个页面有两个功能，一个是提交给下一个人，一个只是单独保存，而不提交


QingjiaForm qingjiaForm = new QingjiaForm();
qingjiaForm.setApplier((String)session.getAttribute("actorId"));
qingjiaForm.setNday(Integer.parseInt(ndays));
qingjiaForm.setReason(reason);

if("commit".equals(actionType)){  
   qingjiaForm.setState(QingjiaForm.SENT); 
}else{
   qingjiaForm.setState(QingjiaForm.INITIAL);
}

JbpmContext jbpmContext = JbpmConfiguration.getInstance().getCurrentJbpmContext();
jbpmContext.getSession().save(qingjiaForm) ; //先把这个表单放到自己的数据库中

if("commit".equals(actionType)){ //如果是提交，那么需要启动工作流引擎

 	WorkflowEngine workflowEngine = ServiceLocator.getWorkflowEngine();
 	
 	Map varMap = new HashMap();
 	varMap.put("infoid",qingjiaForm.getId());
 	
 	//因为是请假，那么流程定义的名字肯定是知道的，这里就叫做qingjia
 	//第二个是提交给谁，这个因为在表单填写的时候由用户指定，当然也是传过来的
 	//String pdname,String starter,String version,Map varMap
 	workflowEngine.startProcess("qingjia",(String)session.getAttribute("actorId"),varMap);

}
