Question

我有一个耳朵的jboss应用程序。内部有战争，战争的WEB-INF文件夹中有文件monitor.tld。

monitor.tld中有一些标签定义。我在此文件中添加了自定义标记定义，然后重新启动了jsboss。之后，当我在jsp中使用我的标签时，我得到错误：

因此，我的自定义标记wizardNavEx不起作用，但在monitor.tld中定义的wizardNav上面几行可以正常工作。

我认为问题是tomcat / jboss在某个地方缓存了以前版本的monitor.tld。我该如何清除缓存？有什么想法吗？

版本：

X-Powered-By ='Servlet 2.4; JBoss-4.2.2.GA（build：SVNTag = JBoss_4_2_2_GA date = 200710221139）/Tomcat-5.5'

Answer 1

问题是其中一个jar文件中存在另一个monitor.tld。

jboss / tomcat tld cache invalidation
