Tomcat项目的部署问题之Error starting static Resources

老话说的好：实践出真知。什么事情都要去做，做了之后才能知道是怎么回事，会发现更多的问题。

刚进公司不久，项目经理叫我熟悉公司的开发框架，给了我一个公司完善的项目，叫我去熟悉。前2天这个项目还好好，后来我把JDK1.6给卸载了(公司要求的开发环境是JDK1.5+struts1.2+hibernate+spring).卸载了之后，发现Tomcat启动不了了，在myeclipse中部署该项目，发现报异常：java.lang.reflect.InvocationTargetException

一直不到解决的方法，后来我又把JDK1.6安装好，配置好1.6的路径，运行OK了，真是折磨人啊·····

可是当把myeclipse关了之后，直接启动tomcat，发现出现了这个异常：严重: Error starting static Resources

开始我以为是Tomcat虚拟路径的问题，改来改去，发现没什么可改的了，去Google了一天，也没有解决问题，后来我想起Tomcat里的JDK还是原来1.5的(我原来1.5的JDK没有卸载，我的环境变量里这两个不同的版本都设置了的)。于是我把Tomcat里的JDK改成1.6版本的，终于解决了。。。。。汗死。。。。。

软件开发真是意见有趣的事情，当你遇到问题的时候，不要慌张，我们都毕业了，意见没有免费的老师来教我们了，那我们就改请教Goolgle这个老师了，遇事要冷静，细心(*^__^*) 嘻嘻……
