关于ssh整合jbpm4.4 无法获取processEngine的问题

先说环境 我的环境是 struts2.1.8+spring2.5.6+hibernate3.5.0+tomcat7.0

错误提示如下

在网上找了很多资料 有说是jbpm4.4与tomcat6.0以上版本jar冲突的

但是试了一下解决办法 也没用

于是开始自己看源码 发现是processhelper的createProcessEngine()方法抛出异常 推测是applicationContext没有注入

于是各种尝试 

最后又回到看错误信息上

发现是 org.jbpm.pvm.internal.id.PropertyImpl的映射问题

于是上网百度了下 org.jbpm.pvm.internal.id.PropertyImpl的映射文件位置

jbpm包下的jbpm.repository.hbm.xml文件 内容如下

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

    </id>
    <version name="version" column="VERSION_" />
    <property name="value" column="VALUE_" />
  </class> 


</hibernate-mapping>

 org.jbpm.pvm.internal.id.PropertyImpl的配置为红色区域 

所以只要在jbpm.hibernate.cfg.xml中添加<mapping resource="jbpm.repository.hbm.xml"/>配置

问题就解决了
