关于JBPM整合SSH框架的问题
内容比较多，请看官耐心！

JBPM有自己的实体hibernate配置文件，我看到他们都在jbpm-jpdl.jar里面，
在网上查资料得到，这些配置与系统本身实体配置放在一起的话，得增加以下代码

XML code

<property name="mappingJarLocations">            <list>                <value>WEB-INF/lib/jbpm-jpdl.jar</value>            </list>        </property>        <property name="mappingLocations">            <value>classpath*:/org/jbpm/**/*.hbm.xml</value>        </property>

这样子，我的配置文件代码就变成这样子

XML code

<property name="mappingJarLocations">            <list>                <value>WEB-INF/lib/jbpm-jpdl.jar</value>            </list>        </property>        <property name="mappingLocations">            <value>classpath*:/org/jbpm/**/*.hbm.xml</value>        </property>            <property name="mappingResources">            <list>                <value>                    com/model/SsSysRole.hbm.xml                </value>                <value>                    com/model/SsSysUserRole.hbm.xml                </value>                <value>                    com/model/SsSysUser.hbm.xml                </value>             </list>        </property>

这样子配置以后，系统启动后报错了，异常如下：

如果去掉那些配置系统启动正常，但是在调用JBPM的方法去查询流程实例时，报错了，大意是找不到实体配置

有搞过JBPM整合SSH的朋友吗，帮帮忙，谢谢！
