在 Eclipse 中将 <listener> 添加到 web.xml 时出现问题

Question

我将 Eclipse 与 Websphere 服务器一起使用。

我需要添加一个会话监听器。我在包 net.test 中添加了类 SessionListener.java 。当我将 标签添加到 web.xml 文件时，我收到以下错误：

Distribution of configuration failed.  See log for details.

    </listener>

当我删除标签时，一切正常...请帮助...我真的需要那个监听器进行清理工作以跟踪当前的在线用户...

这是 WASCE 中的一个（讨厌的）错误。应该是"file:///C:/Program Files/IBM/...."。 file:// 是由于Program Files 中的空格而丢失的协议。 IBM 的人应该引用路径名，但他们显然忽略了它。

要解决此问题，请将 WASCE 安装在没有空格的路径中，或者升级到可用的最新版本。
