初次配置Struts2环境碰到的一系列问题汇总
开发环境
Eclipse:
Eclipse Java EE IDE for Web Developers.
Version: Helios Service Release 1
Build id: 20100917-0705
Tomcat：
apache-tomcat-6.0.16
Struts：
struts-2.2.1.1
正确的引入
4.如果以上问如果以上问题都解决完了，还是提示缺少某些jar包的话可以考虑查看Tomcat的classpath，那些缺少的jar包放到里面去：在Eclipes的servers view 中双击Tomcat->Open launch configuration 进入Edit configuration 界面，然后增加tomcat启动加载的jar包。这样tomcat每次启动都会自动加载这些jar，当然此方法利弊参半，请慎重考虑。
