getClassInstance Line: 209 - com/opensymphony/xwork2/spring/SpringObject 请大家帮我看看

[悠悠隐于市]

框架采用Struts2+Spring2.5+Ibatis2.16 整合好之后， 部署在tomcat6.0上面一切正常， 如果部署在Websphere Application Server上面就报下面这个错误，
找了很久都没有找到是什么原因造成的， 如果遇到该问题的 请说下您的解决方案：

请大家帮忙看看是什么原因。。。

[悠悠隐于市]

我在解决该问题的时候，试图使用过如下解决方式:

1、Struts的Filter配置
在web.xml配置文件
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

2、Spring的监听器配置 。

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

3、struts2-spring-plugin-2.1.8.1.jar 是否加入.
确定已经加入。

4、Struts的对象工厂是否配置正确
在struts.xml中设置struts action托管给spring管理。
<constant name="struts.objectFactory" value="spring" />

都没有成功该解决。

没有人吗? 自己顶一下。

[莫欺少年穷]

同lz、求解

[softroad]

不会spring的说，

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

nullpointexception 可能少什么配置了，找本书看看啊

楼主说的四步我都一一验证了 还是有错求解答？
---------------------------------web.xml-----------------------------------
<context-param>
<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext*.xml,classpath*:applicationContext*.xml</param-value>

</context-param>
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

去你的web-info的lib下面检查包，有的包冲突的！这个问题很难找的 我以前遇到过，不过被我们项目经理找到了 找了两个小时
