S2SH报错求助

[KinsFong]

S2SH框架整合完以后运行后爆了个奇怪的错误，搞了我大半天也百思不得其解，故请大牛们鉴定，呵呵

Tomcat错误信息如下：

杯具了。我估计是struts.xml里面还缺了什么配置，但是网上找了很久，都找不到，又说要删包导包，又说修改它的继承节点，都试过了，也没用，下面是web.xml代码

[dingxinzhang]

第一次错误原因
Caused by: Action class [ShowNewsListAction] not found - action - file:/F:/tomcat/webapps/TestNews/WEB-INF/classes/struts.xml:13:31
struts的action没有交给spring代理
后来你加了<constant name="struts.objectFactory" value="spring" />这句话就对了

第二此错误建议把applicationContext.xml中bean都去掉，只保留action配置，在启动看下，逐步排查，肯定是配置错误了

[KinsFong]

测试完了.肯定是struts.xml里面配置的问题，但就是看不出有什么问题

把applicationContext.xml里面的beans全删掉以后，还是爆相同的错误

把struts.xml里面的配置和action都干掉了就不报错了..费解中

有时tomcat还会在原来的错误下面爆多一个如下的错误

试过修改web.xml的引用顺序了.还是爆相同的错误

应该不关web.xml的事,以前这样写都是正常运行的

[KinsFong]

下面是applicationContext.xml的代码

配置文件的路径都绝对没错的，就是不知道为什么

明天解决不了问题的话，就贴上打包rar的下载地址吧,呵呵,谢谢!

[KinsFong]

试过把struts.xml里的代码改成

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

			class="ShowNewsListAction">
			<result name="success">/ShowNewsList.jsp</result>
		</action>
		
	</package>

</struts>

也是一样不行，但报错信息有点变了，如下........

[KinsFong]

问题解决了..
因为我得代码是struts2.0的代码.但我却导了struts2.6的包..
那当然会报错了.这个一定要很小心,因为struts自2.0以后每个版本的配置文件编写方式都有点不同..

[KinsFong]

上面写错了.是我却导了struts2.3的包
