		<description><![CDATA[在试图将工作流发布到WebLogic11g即WebLogic10.3中时遇到了比较棘手的异常信息：ClassNotFoundException: org.hibernate.hql.ast.HqlToken，在经过查询资料并进行代码追踪和研究后发现产生该异常的原因是：在jBPM4.0中，使用的Hibernate是3.0之后的版本，而从3.0开始就采用了新的基于ANTLR的查询翻译器，在WebLogic中使用的是antlr2.6.1.jar，无法满足该要求，需要从新版本的Hibernate中提取该jar并添加到WebLogic的Classpath中。

		<description><![CDATA[审批工作流是对jBPM综合使用的一个展现，由于实现整个审批工作流涉及较多内容，因此将分为多次来描述
工作流主要实现了如下的功能： 
1，根据职位层次进行逐层往上提交审批 
2，实施人员可以设置审批层次(目前通过后台表) 
3，职位的审批权限根据金额范围来判断 
4，实施人员可以设置职位的审批金额(目前通过后台表) 
5，审批的提醒通过代办事项来实现

整个工作流涉及的关键知识点有：
1，TaskNode节点类型 
2，Node节点类型 
3,ActionHandler的扩展 
4，上下文 
5，动态创建任务实例 
6，任务实例工厂扩展 
7，Hibernate持久对象的扩展
