caching - jboss/tomcat tld 缓存失效

Question

我有一个带有耳朵的 jboss 应用程序。 ear里面有war，war的WEB-INF文件夹里面有文件monitor.tld。

monitor.tld 中有一些标签定义。我在这个文件中添加了我的自定义标签定义，并重新启动了 jsboss。之后，当我在 jsp 中使用我的标签时，出现错误:

因此，我的自定义标记 wizardNavEx 不起作用，但是在上面几行的 monitor.tld 中定义的 wizardNav 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。我怎样才能清除缓存？有什么想法吗？

版本:

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

Answer 1

问题是另一个 monitor.tld 存在于其中一个 jar 文件中。
