Java Tomcat 启动 (web.xml) 问题

Tomcat startup (web.xml) issue

提问by Evan Klein

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:

我将 Tomcat 6 与 Eclipse Web 工具一起使用来发布应用程序。当我部署 j2ee 应用程序时，我通过 tomcat 日志收到此错误：

SEVERE: A web application appears to have started a thread named [JotmClock] but has failed to stop it. This is very likely to create a memory leak.

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.

这将我带到 web.xml 文件 - 显然正在解析问题。但是，在检查 web.xml 时，我没有发现任何错误。

Here is the web.xml:

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.

1. 将初始行“<web-app”更改为以下内容

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

2. 在整个文件中，删除任何“javaee:”前缀。

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.

我有同样的问题，我想我们都从同一个来源复制了 web.xml 文件。我不记得来源是什么，直到现在它对我有用，我不知道发生了什么变化。

This is your problem:

这是你的问题：

SEVERE: Parse error in application web.xml file at jndi:/localhost/aramark-optima/WEB-INF/web.xml

严重：在 jndi:/localhost/aramark-optima/WEB-INF/web.xml 处解析应用程序 web.xml 文件中的错误

This isn't a valid JNDI lookup. Where is this spelled out?

这不是有效的 JNDI 查找。这是在哪里写的？

回答by Gangadhar

As everyone mentioned its a problem with web.xml the web.xml do gets updated, when you are updating the "User Library" in Eclipse IDE, i.e. after downloading respective library jar it updates the web.xml by default.

正如每个人都提到的 web.xml 的问题，web.xml 确实会更新，当您在 Eclipse IDE 中更新“用户库”时，即下载相应的库 jar 后，默认情况下它会更新 web.xml。

Immediately you need to restore your web.xml else you would get this error.

您需要立即恢复您的 web.xml，否则您会收到此错误。

回答by BIdesi

I also faced this error when renaming the project (eclipse changed the web.xml file completely) . Fixed it by restoring.

我在重命名项目时也遇到了这个错误（eclipse 完全改变了 web.xml 文件）。通过恢复修复它。
