Question

我已经为现有标签添加了一些新功能，并修改了相应的tld并将其放在WEB-INF /上。但有些tomcat没有选择这个修改过的.tld

我在这里做错了什么我需要把.tld文件覆盖在jar中的现有文件？以下是例外

Answer 1

您应该使用实现它的.class文件将.tld放在JAR中。

查看Apache JSTL standard.jar，了解如何正确执行此操作。

Answer 2

可以通过指定标签的uri来覆盖.tld

  <%@ taglib uri="/WEB-INF/test.tld" prefix="testing" %>

覆盖jar中的.tld文件
