老是出现type Status report
message /Struts2_0100_Introduciton/Hello.jsp
description The requested resource is not available.
到底是哪里出错了，struts用的2.341，Myeclipse8.5
[解决办法]
404，很明显，路径不存在
你看看
message /Struts2_0100_Introduciton/Hello.jsp
这个页面在么？
注意大小写。
hello.jsp才对。
注意struts跳转的时候原有的文件路径。
[解决办法]
+1
[解决办法]
你截个图我看下，就是jsp放在webROOT下的那个图片。我感觉除非你设置了过滤器或者拦截器给过滤了，要不一般不会出现这样的情况。
[解决办法]
<filter>过滤器改为这个。struts.xml里面配置的跳转试图是Hello.jsp，你就要建Hello.jsp文件。
