Java EE，Eclipse，Tomcat简单Servlet启动错误

-2

尝试启动简单Servlet程序（Hello Servelt）在声明tomcat服务器时抛出异常。Java EE，Eclipse，Tomcat简单Servlet启动错误

我检查并确认我进入了Window-> Preferences-> Server-> Runtime Environment-> Apache Tomcatv7.0-> Edit->，并查看了Tomcat安装目录字段，以确保我处于正确的根目录。

有帮助表示赞赏。

这是一个问题？ –

检查你在你工作的盒子上有管理员权限。 –

它看起来像有在web.xml一个错误，因为建议的这条线的异常：

Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> xmlservletpath in servlet mapping

你的问题提出了非常糟糕。没有关于你想要做什么的文本提示，没有关于你想要显示的应用程序的数据等。

无论如何，请检查您尝试部署的应用程序的web.xml。显然，你必须与URL模式的值无效宣告有一个servlet，如宣布你的错误消息：

servlet映射“在servlet映射无效xmlservletpath”似乎从错误堆栈错误。你不应该发布到SO。
