JSF h:commandlink 更新版本后不工作

Question

我正在努力将一个应用程序从 websphere 迁移到 tomcat，这在很大程度上是完全成功的。之前的应用程序是 Java EE 5 上的运行，我将其更新为 Java 7。在此过程中，我将 JSTL 更新为 1.2，将 myfaces 更新为 2.0，以及一些其他内容。这是我当前的 jar 库：

Library of Jars

除了 h:commandlink 之外，关于应用程序的一切都正常。我相信这与更新 jars 和 java 版本有关。我可以访问所有其他页面，只是导航按钮不起作用。这是他们的jsp：

单击 link 时，假设调用此 class 中找到的相应方法。然而，它从未真正进入这个 class。假设在索引中进行调用，然后根据导航规则它 returns 正确的视图，但它永远不会进入正确的方法。

}

onclick 与之前运行的不同，这让我相信它与版本有关，但我没有找到任何与 onclick 为何会发生变化相关的信息。

上一个 onclick 是：

<a id="viewFragmentMain:formMenu:link2" href="#" onclick="document.forms['viewFragmentMain:formMenu']['__LINK_TARGET__'].disabled=false;document.forms['viewFragmentMain:formMenu']['__LINK_TARGET__'].value='viewFragmentMain:formMenu:link2'; document.forms['viewFragmentMain:formMenu'].submit();document.forms['viewFragmentMain:formMenu']['__LINK_TARGET__'].disabled=true; return false;"><span id="viewFragmentMain:formMenu:textMenu2" class="outputText">My Requests</span></a>

新的 onclick 是：

<a href="#" onclick="return myfaces.oam.submitForm('viewFragmentMain:formMenu','viewFragmentMain:formMenu:link2');" id="viewFragmentMain:formMenu:link2"><span id="viewFragmentMain:formMenu:textMenu2" class="outputText">My Requests</span></a>

简单地说，我想我想问的是如何使新的 link 看起来像更新版本的旧版本？

Answer 1

什么版本的 WebSphere？通常你不能在你的应用程序中捆绑 JSF 实现 jar，除非你明确地想要覆盖 WAS 中捆绑的那个。如果是这样，请查看文档 here

Answer 2

我发现问题与使用仍然 "in use" 的旧 Websphere jar 有关。我有上面的标签库，IBM 面孔使用前缀 hx。这仅适用于 Websphere 服务器。因此，在删除它们的过程中，我不得不重做已实现的标签，其中大多数都有简单的等价物。另一个出现的问题，在它的后端，我们为 IBM Faces 实施，所以我目前正在重写以合并实际使用的标签。我还必须更改仍设置为包含 IMB 上下文参数的 web.xml，因此我删除了它们。

正如您在这里看到的，我删除了允许链接工作的 hx 标签库，并且没有任何问题。我还必须从 web.xml 文件中删除所有提及的 IBM 实例和来源。
