无法“在服务器上运行”来自Eclipse的webapp [英] Unable to "Run on Server" a webapp from Eclipse

问题描述

当从Eclipse运行WebApp项目时，大多数情况下它正常运行。但是如果错误地停止服务器，我在控制台视图中将其删除而不是服务器视图中的停止服务器。
运行清洁项目时，我得到这个

When running my WebApp project from Eclipse most of times it run correctly. But if by mistake to stop server, I kill it in "Console" view on instead of "Stop" Server from "Servers" View. While running clean project I get this

在启动时，我得到这个

请帮忙从中恢复。

推荐答案

我已经停止使用这种运行webapp的方法。
我使用 mvn tomcat：运行。更容易虽然我不知道如何调试。

I have stopped using this method of running my webapp. I use mvn tomcat:run instead. Much easier. Though I don't know how to debug.
