请教：spring+hibernate+jbpm整合失败

这两天打算将jbpm和spring整合到一起，折腾了半天还是失败了。

下面将我的整合步骤简单描述一下：

首先我用 eclipse3.2+spring2+hibernate3.2 结合做了一个小例子，运行成功，使用的是声明式的事务。

接着我在上面的例子上加载了 spring-modules-0.6，因为这个模块里加载的是jbpm-3.1.1.jar而且还缺少了jbpm-identity-3.x.jar，于是我用jbpm3.1.2替换到了3.1.1，将我能够单独运行成功的websale例子按照spring-modules提供的手册上面的步骤进行了配置，一运行，jbpm的表正确生成了，但是生成jbpmConfiguration失败了，跳出了异常：

下面是我的spring关于jbpm的配置

<!-- reading jBPM process definitions -->
    <bean id="websaleWorkflow1" class="org.springmodules.workflow.jbpm31.definition.ProcessDefinitionFactoryBean">
        <property name="definitionLocation"    value="processdefinition.xml"/>
    </bean>
    <!-- jBPM configuration-->
    <bean id="jbpmConfiguration" class="org.springmodules.workflow.jbpm31.LocalJbpmConfigurationFactoryBean">
        <property name="sessionFactory" ref="sessionFactory"/>
        <property name="configuration" value="jbpm.cfg.xml"/>
        <property name="processDefinitions">
            <list>
                <ref local="websaleWorkflow1"/>
            </list>
        </property>
        <property name="createSchema" value="true"/>
    </bean>
    <!-- jBPM template -->
    <bean id="jbpmTemplate" class="org.springmodules.workflow.jbpm31.JbpmTemplate">
        <constructor-arg index="0" ref="jbpmConfiguration"/>
        <constructor-arg index="1" ref="websaleWorkflow1"/>
    </bean>

检查 sessionFacory 配置 jbpm 相关 *.hbm.xml .

应该是这里的问题.

我的spring配置文件
<!-- Hibernate SessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource"/>
</property>
</bean>
没有定义mapping xml，所有jbpm mapping是在hibernate.cfg.xml中.可以生成jbpm的那些表。
