朋友。。。
你这类型转换异常是插件问题引出的，把插件去掉就ok了

java.lang.ClassCastException: com.intellij.psi.impl.source.jsp.impl.WebDirectoryElementImpl cannot be cast to com.intellij.psi.PsiFile
恩 我也觉得是插件问题
idea已经够强大了不用再装插件了
难道你是想自己开发插件啊

[wycarole]

问题是不是出现在包的配置和引用上啊

[ojwftded]

你的idea配置tomcat的时候出错了吧，怎么会有这样的异常？把你邮箱给我吧，我写了一个idea7的tomcat的配置方法，虽然你的是idea8，但是大同小异，我给你发过去
