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：
