java - JSF h :commandlink not working after updating version

Question

我正在致力于将应用程序从 websphere 迁移到 tomcat，这在很大程度上是完全成功的。之前的应用程序在 Java EE 5 上运行，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，以及其他一些内容。这是我当前的 jar 库:

Library of Jars

除了 h:commandlink 之外，应用程序的所有内容都有效。我相信这与更新 jar 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:

当单击链接时，应该调用此类中的相应方法。然而，它实际上从未进入这个类别。它应该在索引中进行调用，然后根据导航规则返回正确的 View ，但它永远不会进入正确的方法。

}

onclick 与之前的不同，这让我相信它与版本有关，但我没有找到任何与 onclick 发生变化的原因相关的信息。

之前的 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，我想我要问的是如何使新链接看起来像更新版本的旧链接？

WebSphere 是什么版本？ 通常，您不得将 JSF 实现 jar 捆绑到您的应用程序中，除非您明确想要覆盖 WAS 中捆绑的 JSF 实现 jar。如果是这样，请检查文档 here
