tomcat一启动就报错，困扰一天了。望帮助
小弟初学Struts2,利用struts2做了个练习。用的是struts2.3.1.2 IDE：MyEclipse8.6.1
启动其他项目没任何问题，就是这struts2才出现问题。tomcat和MyEclipse都重装了，但还是没解决。参照了一些网上的办法，还是没法解决

在线求助，先道谢啦
[解决办法]
应该是Struts2 的相关包有问题...
[解决办法]
严重: Exception starting filter struts2
java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils
少东西了。应该是你自己定义的类！
[解决办法]
你试试看只把框架导进去,,,不写任何代码,,,看看运行是不是有问题...
[解决办法]
struts2-core-2.3.1.2.jar重新倒下
这个版本struts还真不知道你的web.xml配置的对不对
[解决办法]
你这是少了文件上传的包
[解决办法]
你jdk重装一下试试，还有环境变量
[解决办法]
几个可能 环境变量 相应的包缺失 类没有编译完全，clean你的工程然后重新编译看看
[解决办法]
加一个commons_lang.jar包
[解决办法]
你先查查org/apache/commons/lang/StringUtils这个类包含在哪个jar包中，然后去网上下载相应的jar包
