我在这里看到了一个类似的主题，但在我的情况下问题并不相同。

在处理 primefaces 数据表 ajax 事件时，我不断得到这个：

 java.lang.NoClassDefFoundError: Could not initialize class org.omnifaces.config.WebXml

而这些行动显然是行不通的。

我的环境如下：

我尝试更改为 Omnifaces 1.1，然后这个问题就消失了，但是使用 1.4 和 1.5 会出现这个异常。我需要使用 Omnifaces 1.4/1.5 的原因是获取 h:inputSecret 占位符属性。我没有在引发异常的页面上使用omnifaces..有人知道我哪里出错了，或者有解决方案吗？

This is what I ended up doing.

I was using Omnifaces to add placeholders to JSF inputFields. I returned to Omnifaces 1.1, who allowed me to add placeholder to < h:inputText>, but not . I don't get the error above with Omnifaces 1.1. I simply used javascript to solve this:

<script type="text/javascript">

            function addPlaceholder() {
                var element = document.getElementById("j_password");
                element.setAttribute("placeholder", "Password");
            }

            window.onload = function() {
                addPlaceholder();
            }
 </script>

It does not fix the error above using Omnifaces 1.4/1.5, but it does solve my problem, which was to add a placeholder to < h:inputSecret>.
