[光义]

 XML validation disabled 

是不是缺少了配置文件???

[kokobox]

宝家族的帅哥：java.lang.ClassFormatError: Extra bytes at the end of class file listeners/ContextListener

没有找到类

仔细检查一下xml配置

[光义]

帮顶个....嘎嘎...

[老紫竹]

java.lang.ClassFormatError: Extra bytes at the end of class file listeners/ContextListener

奇怪，难道你的jar坏了？

[光义]

这种提示是jar坏了???

没遇到过这东东...

在顶个..

[catslee]

是不是xml位置方错了～～！

[dendai1]

呵呵。编译和运行代码的jdk版本不一样。

[dendai1]

在eclipse上设置一下jdk的版本啦

[Shine_Panda]

把 jar考到lib目录看看。

[hepeng19861212]

刚才在IE输入localhost:8080,发现tomcat已经启动了，但是：第一，我看了“服务”，里面显示tomcat并未启动。2。我打开tomcat monitor，但是没有启动tomcat，所以桌面右下角那个tomcat图标显示的是关闭。3。我看了任务管理器，里面没有tomcat，apache之类的进程。

[hepeng19861212]

但是如果我把index.jsp放到webapp目录下面，然后手工启动tomcat,ie是可以显示index.jsp的.
