我开发了一个Spring MVC应用程序，它在Glassfish和Jetty上运行良好。现在我需要在Websphere Liberty版本8.5.5.7上部署该应用程序。它在很大程度上运行良好，但有些页面无法加载，但有以下异常（见下文）。
这些页面的共同点是它们使用生成模板页面的自定义标记。这样的页面的一个示例是：
<%@page contentType="text/html" pageEncoding="UTF-8" %>
<%@taglib prefix="t" tagdir="/WEB-INF/tags" %>
<t:genericadminpage>
<jsp:body>
</jsp:body>
</t:genericadminpage>
为了解决这个问题，我将pom.xml中包含的JSTL库的范围切换为provided，这解决了某些页面的问题，但将其引入其他页面。 / p>
希望有人对这里发生的事情有所了解，并且可以对此有所了解。如果您需要更多信息，请询问。
提前谢谢。

如果您尝试使用WebSphere Application Server中提供的jstl库，那么我建议您从应用程序中删除jstl.jar和standard.jar文件。基于异常，运行时似乎与生成的标记类文件混淆。这可能是由类路径上的两个不同的jstl jar引起的。我还会清除之前编译的任何标记类文件，这些文件是为了确保在删除jar文件的情况下创建新文件。
如果这不能解决您的问题，那么请您提供有关自定义标记内容的更多详细信息。 问候， 杰
