在jsf中配置错误页面时出错？ [英] Error in configure to error page in jsf?

问题描述

在我的项目中，当我的代码中出现特定错误时，我必须显示错误页面。

我在header.xhtml页面中添加了以下脚本。此页面被添加到每个页面。因此，每当出现错误时，我想显示错误页面。

In my project I have to display a error page when specific errors occurs in my code.
I have added the following script in my header.xhtml page.This page is added to each and every page.So whenever error occurs I want to display error page.

<script type="text/javascript">
            A4J.AJAX.onExpired = function(loc, expiredMsg) {
                window.location = "../facelets/error/invalidSessionLogin.jsf";
            };

            A4J.AJAX.onError = function(req, status, message) {
                window.location = "../facelets/error/ajaxError.jsf";
            };
        </script>

但这不起作用。

我还配置500,404错误在web.xml中。代码如下。

but this is not working..
And I also configure for 500,404 error in web.xml.The code is as follows.

 <context-param>
        <description>Use this to suppress Facelets error page</description>
        <param-name>org.apache.myfaces.ERROR_HANDLING</param-name>
        <param-value>false</param-value>
    </context-param>
     <error-page>
        <error-code>500</error-code>
        <location>/facelets/error/internalErrorHome.jsf</location>
    </error-page>
    <!-- if required page not available -->
    <error-page>
        <error-code>404</error-code>
        <location>/facelets/error/pageNotFoundErrorHome.jsf</location>
    </error-page>

但这会给我以下错误。

11:41:30,618 ERROR [[localhost]] Exception Processing ErrorPage[errorCode=404, location=/facelets/error/pageNotFoundErrorHome.jsf]
com.sun.faces.context.FacesFileNotFoundException: /facelets/error/pageNotFoundErrorHome.xhtml Not Found in ExternalContext as a Resource

我不喜欢我不知道我哪里错了..
我不知道在ExternalContext中找不到的错误作为资源

I don't know where I am going to wrong.. I don't get it the error Not Found in ExternalContext as a Resource

推荐答案

1. 您应该测试您提到的路径是否可访问，如果路径不起作用，请先修复路径。

1. You should test whether the path you have mentioned is reachable or not, and firstly fix the paths if they are not working.

为什么不为这些错误代码创建导航案例，然后设置相应的URL，而不是使用相对路径。

Why don't you create a navigation case for these error codes and then instead of using relative paths, set the appropriate urls.

window.location =$ {request.contextpath} / error / 404;

window.location = "${request.contextpath}/error/404";

例如：

   mywebapp
   |
   |---WEB-INF 
   |
   |---error
   |    |
   |    |---404.xhtml

  (and so on)

In web.xml：

In web.xml:

 <error-page>
     <error-code>404</error-code>
     <location>/error/404.xhtml</location>
 </error-page>

并且类似于500个错误代码。

and similarily for 500 error-code.
