RequestDispatcher.forward（）到“/ WEB-INF”下的资源在WebSphere中不起作用 [英] RequestDispatcher.forward() to resource under "/WEB-INF" doesn't work in WebSphere

问题描述

在我的一个servlet中，我调用 RequestDispatcher.forward（）调用WEB-INF文件夹下的某个静态资源：

In one of my servlets, I invoke RequestDispatcher.forward() call to a static resource somewhere under WEB-INF folder:

request
    .getRequestDispatcher( "/WEB-INF/some/path/image.gif" )
        .forward( request, response );

导航到这个servlet在Tomcat，Jetty等下工作正常，但在WebSphere 7中不起作用。
我得到的错误（在浏览器和服务器日志中都是）

Navigating to this servlet works fine under Tomcat, Jetty et al., but does not work in WebSphere 7. The error I get (both in the browser and in the server logs) is

Error 403: SRVE0190E: File not found: /WEB-INF/some/path/image.gif

最初我认为WebSphere可能需要一些特定的配置来允许内部转发到WEB-INF下的资源，但我没有谷歌任何有用的东西。

Initially I assumed that WebSphere may need some specific configuration to allow internal forwarding to resources under WEB-INF, but I failed to google anything useful.

任何想法为什么会发生这种情况？

Any ideas why can this happen?

提前致谢！

推荐答案

看来应该设置 exposeWebInfOnDispatch 属性为 true ，以便为WebSphere中的servlet提供WEB-INF。我从 WebSphere论坛。

It appears that one should set exposeWebInfOnDispatch property to true in order to make WEB-INF accessible for servlets in WebSphere. I got this answer from WebSphere forum.

在WebSphere 7管理控制台中，

In WebSphere 7 administration console,

1. 转到服务器=>服务器类型=>WebSphere应用程序服务器左侧
   


2. 选择


3. 单击容器设置=>Web容器设置=>Web
   容器


4. 转到右侧的自定义属性



5. 添加新属性：

1. Go to "Servers" => "Server Types" => "WebSphere application servers" on the left
2. Choose proper server on the list on the main part of the page
3. Click on "Container Settings" => "Web Container Settings" => "Web container"
4. Go to "Custom properties" on the right

5. Add new property:

• 名称： exposeWebInfOnDispatch


• 值： true

• Name: exposeWebInfOnDispatch
• Value: true
