The following error occurred during schema generation: n(spring+hibernate+axis2)

我用spring2.5+hibernate3.2+axis2，测试spring配置成功，配置axis2时总会报The following error occurred during schema generation: null,困扰我好几天了，请高手指点一二
我的services.xml配置如下：
<service name= "TestWebService" >
    <description>first axis2 example</description>
<parameter name="ServiceObjectSupplier"
locked="false">org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier</parameter>
    <parameter name="SpringBeanName" locked="false">myservice</parameter>
    <messageReceivers>
     <messageReceiver mep= "http://www.w3.org/2004/08/wsdl/in-out"
             class = "org.apache.axis2.rpc.receivers.RPCMessageReceiver"  />
        <messageReceiver mep= "http://www.w3.org/2004/08/wsdl/in-only"
             class = "org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"  />
    </messageReceivers>
</service>
web.xml配置如下：
<listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
   <param-name>contextConfigLocation</param-name>
       <param-value>classpath*:applicationContext-*.xml</param-value>
</context-param >

<servlet>
        <servlet-name>AxisServlet</servlet-name>
        <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>AxisServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>
applicationContext.xml配置如下：
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation"
value="classpath:hibernate.cfg.xml">
</property>
</bean>
<bean id="applicationContext" class="org.apache.axis2.extensions.spring.receivers.ApplicationContextHolder"></bean>

<bean id="organizationDao" class="com.zero.webservice.OrganizationDao">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>


<bean id="SpringWebService" class="com.zero.service.impl.SpringwebserviceImpl" >
<property name="organizationDao" ref="organizationDao"></property>
</bean>
<bean id="myservice" class="com.zero.service.impl.MyWebService" >
<property name="SpringWebService" ref="SpringWebService"></property>
</bean> axis2 spring+axis2 --------------------编程问答-------------------- 网上例子很多，但大多千篇一律，求解？ --------------------编程问答-------------------- 已经调试出来了，在http://blog.csdn.net/wokao_wg/article/details/6615007#comments的基础上作了下修改，按照博客上所写的，总是会报：The following error occurred during schema generation:null，无论我用什么版本的axis2 。
所做修改：1、加了这个参数<parameter name="ServiceClass">接口</parameter> 2、<parameter name="ServiceObjectSupplier">org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier</parameter> 3、webService类我用的是类注入 --------------------编程问答-------------------- 具体是什么原理，目前我也不太清楚..
