struts2出错
struts2
--------------------编程问答--------------------
刚学struts2，按着视频做的程序，出现这些问题，在网上查了很多，都不好使。
--------------------编程问答--------------------
Caused by: java.lang.ClassNotFoundException: javassist.ClassPool，javassist.jar这个jar包没有导入，你可以试一试导入一下，jar包也就是在struts的哪些jar包一起，
--------------------编程问答--------------------
看最下面的那个异常信息Caused by: java.lang.ClassNotFoundException: javassist.ClassPool
搜索这个jar包 --------------------编程问答-------------------- <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>这句是不是写错了啊，我记得好像有个ng什么的，帮你查查……
<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> --------------------编程问答-------------------- Caused by: java.lang.ClassNotFoundException: javassist.ClassPool --------------------编程问答-------------------- commons-logging-1.1.3.jar
这个包少了吧
asm是实现啥功能？建议删掉多余不用的jar包。 --------------------编程问答-------------------- Caused by: java.lang.ClassNotFoundException: javassist.ClassPool ，看看有没有javassist.jar,实在不行，把struts包全部导进去 --------------------编程问答--------------------
工程里已经导入javassist-3.11.0.GA.jar。 --------------------编程问答--------------------
全倒入也还是这样。 --------------------编程问答--------------------
导入commons-logging-1.1.3.jar也不行 --------------------编程问答-------------------- 你的filter配错了，改成这个
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter --------------------编程问答-------------------- 少jar ，struts 的配置文件也错了 --------------------编程问答-------------------- 三楼 六楼正解。。。 --------------------编程问答-------------------- 按照上面说的方法试过了也不行，后来换了个tomcat7就没问题了，我原来tomcat里有这些包，是包有冲突或缺少包么？
原来tomcat的包
新的tomcat7的包
补充：Java , Java EE
