1、错误里面有这句话：

omscq.control.security.TreeMenu.doGet(Unknown Source)

找了很久原因没找出问题!

Firefox报错：

在left下这个句话window.location.href ="treemenu"; 是通过servlet找到web.xml中的omscq.control.security.TreeMenu这个class读取的吧！

不知道servlet是否成功！不成功吧，从错误的迹象上看，说treemenu没找到；说成功的吧，通过查看资料和测试都成功了的！

Web.xml：

<?xml version="1.0" encoding="UTF-8"?>

2、错误里面还有这样一句话：org.apache.jasper.JasperException: Missing resource 'temp/008906_8.xml'

这个应该是系统内部的吧！我把url+ temp/008906_8.xml 是找得到源的！

我觉得你这样手动查找资源是可以找到，但是可能是你的XML文件配置出错了，导致tomcat无法查找到资源项，你还是仔细查找下TreeMenu.doGet（）方法中的代码是否有错误或者不规范的地方，详细的测试下吧！

.xml 文件出错几率很小，因为这个项目之前在用，之前在linux平台，先在window平台而已

这个问题是错在查找文件(008906_8.xml)的时候，路径出错,建议打印出相关的路径，就可以找出bug了..

看了一下代码：

1 String s2 = getServletContext().getRealPath("/");
2                      String s3 = (new StringBuilder()).append("temp/").append(user.getUserId()).append("_").append(s1).append(".xml").toString();
3                      String s4 = (new StringBuilder()).append(s2).append(s3).toString();
4                      File file = new File(s4);

这几个是bug的关键...

大家可以一起交流：hongtenzone@foxmail.com

这个路径问题，我也查多，没什么问题！这样这个项目这块我分离出来了，我给你omscq，帮调试下，我的确找不到原因了。

@seen8com:

1.还有个方法，就是把路径修改一下，再做测试...

2.如果不行的话，看一下你的路线下面有没有这个008906_8.xml文件，如果有的话，使用他的绝对路径
