如何让错误页面（HTTP 500）的工作ICEfaces的？

本文介绍了如何让错误页面（HTTP 500）的工作ICEfaces的？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 使用ICEfaces的2，如果执行一个操作方法在标准（=不ICEfaces的）H过程中出现错误：的commandButton，它只是似乎按钮没有作用。未显示错误页面，虽然它被配置为这样做在web.xml中。Using Icefaces 2, if an error occurs during execution of an action method on a standard (=not icefaces) h:commandButton, it just seems the button has no action. No error page is displayed, although it is configured to do so in web.xml.我可以使它工作由周围的标签I can make it work by surrounding the tag with <f:ajax disabled="true">...</f:ajax>不过，我想无论是从ICEfaces的禁用该自动阿贾克斯（见问题如何禁用标准组件unsollicited阿贾克斯（H：的commandButton）在使用ICEfaces的？），或者使错误页面的工作呢。But I'd want to either disable this automatic ajax from Icefaces (see question How to disable unsollicited ajax on standard components (h:commandButton) while using Icefaces? ), or make the error page work anyway. JSF实现Mojarra 2.1里面自带的Glassfish 3.1。JSF implementation is Mojarra 2.1 which comes with Glassfish 3.1.推荐答案最根本的问题是，ICEfaces的抓住了提交按钮，使阿贾克斯在里面。我觉得这简直是恶劣的行为：据我所知，这样的事情会发生在一个冰：的commandButton甚至在冰：形式，但它发生在H：命令按钮来H：形成为好。这可以被禁用，按 http://wiki.icefaces.org/display/ICE/Configuration ，由autorender上下文参数设置为false，在web.xml中。但是，你需要明确地让每个ICEfaces的形式这种行为（否则你会得到一个错误）。The basic problem is that Icefaces captures the submit button and puts ajax in it. I think this is simply bad behavior: I understand that something like that could happen in a ice:commandButton or even under ice:form, but it happens to h:commandButton to h:form as well. This can be disabled, as per http://wiki.icefaces.org/display/ICE/Configuration , by setting autorender context parameter to false in web.xml . But then, you need to explicitely enable this behavior on every icefaces form (you get an error otherwise).总之，正如这里： http://wiki.icefaces.org/display/ ICE /处理+例外，将在页面这个脚本基本上解决了这个问题：Anyway, as stated here: http://wiki.icefaces.org/display/ICE/Handling+Exceptions, putting this script in the page basically solves the problem: //Assign your error handling function to a variable var iceErrorCallback = function iceHandleError(statusCode, responseTxt, responseDOM) { //Handle all errors by simply redirecting to an error page window.location.href = "./generalError.xhtml"; } //Safely check if ICEfaces is available if (ice) { //Turn off the popups as we plan to handle this ourselves ice.configuration.disableDefaultIndicators = true; //Register your error handler as a callback ice.onServerError(iceErrorCallback); }更新：我不得不修补一些ICEfaces的的JavaScript为它工作，见的http：// JIRA .icefaces.org /浏览/ ICE-6546 。我知道实现正常ICEfaces的行为显示与错误，这并没有发生弹出。Update: I had to patch some Icefaces javascript for it to work, see http://jira.icefaces.org/browse/ICE-6546 . I know realize normal Icefaces behavior is displaying a popup with the error, which didn't happen. 这篇关于如何让错误页面（HTTP 500）的工作ICEfaces的？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
