【求助】java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor

JunitLive 2012-02-12 06:57:51
在做SSH2整合测试，其中Struts2因为想用Annotation配置，所以在web.xml中加入下列语句：
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<!-- 这里配置struts的action扫描路径 -->
<init-param>
<param-name>actionPackages</param-name>
<param-value>kun.action</param-value>
</init-param>
</filter>

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

然后启动Tomcat时遇到下面异常：
二月 12, 2012 6:49:34 下午 org.apache.catalina.core.StandardContext filterStart
严重: Exception starting filter struts2

严重: Context [/Spring_S2SH_1000_Registration] startup failed due to previous errors

这个异常网上找了很多解决办法，但都没用，无非就是说jar包冲突，但时试了很多次，发现还是这个问题：
请各位大侠看下，帮小弟解决一下。。。

解决java.lang.NoClassDefFoundError: org/objectweb/asm/Type
CGLib缺少jar出现 java.lang.ClassNotFoundException: org.objectweb.asm.Type CGLib实现动态代理区别于JDK动态代理，不需要目标类实现任何接口，是通过生成代理类子类的方式，而且据说速度要快于JDK动态代理。所以我想要试验一下CGlib的动态代理，网上找了些例子，自己动手写了一个Demo，运行时抛出以下异常 Exception in thread "main" java.lang.NoClassDefFoundError: org/o.

J2EE只是Java企业应用。我们需要一个跨J2SE/WEB/EJB的微容器，保护我们的业务核心组件（中间件），以延续它的生命力，而不是依赖J2SE/J2EE版本。
