Answer 4

貌似不是代码的问题。
好像是少了library 
重装一下tomcat吧。再重新载入一遍jar包试试。

Answer 5

tomcat 下载安装以后，要运行一下试试是不是能运行起来，如果运行不起不来，那就是大环境没配置好；如果能运行起来，但是把自己的war挂上去运行不起来，那就是自己的程序没配置好，要在自己的程序包内找原因。

Answer 6

少jar包，struts2-core-2.2.3.jar有吗

Answer 7

Caused by: java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUpl
oadException你把apache的fileupload包加上

Answer 8

Caused by: java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUpl
oadException
把fileuploadexception类所在的jar包放到lib下。
jar包网上狗狗下就行了。
