问题描述

我正在使用Tomcat 6和eclipse web工具来发布应用程序。当我部署j2ee应用程序时，我通过tomcat日志得到这个错误：

 SEVERE：一个web应用程序似乎已经启动了一个名为[JotmClock]的线程，但未能阻止它。这很可能造成内存泄漏。

这会将我导向到web.xml文件 - 这显然会解析问题。但是，在检查web.xml时，我没有看到任何错误。

解决方案


  1. 更改

     < web-app xmlns =http：// java .sun.com / XML / NS / JavaEE的>


  2. 在整个文件中，删除所有javaee：前缀。 >


我有同样的问题，我想我们都是从同一个源复制web.xml文件。我不记得来源是什么，直到现在，我都不知道是什么改变了。


I'm using Tomcat 6 with eclipse web tools to publish an application. When I deploy the j2ee application I'm getting this error via tomcat logs:

This leads me to the web.xml file - which apparently is having issues being parsed. However, when examining the web.xml I don't see anything wrong.

Here is the web.xml:

解决方案

  1. Change the initial line "<web-app" to the following

    <web-app xmlns="http://java.sun.com/xml/ns/javaee">

  2. Throughout the entire file, remove any of those "javaee:" prefixes.

I had the same problem, I think we both copied the web.xml file from the same source. I can't remember what the source was and it worked for me until now, I don't know what changed.
