Unable to “Run on Server” a webapp from Eclipse

Question

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 \"

Answer 1

Tried everything with no luck. I just had one project in my eclipse. Shut eclipse down, rename the eclipse directory, unzip it again, started fresh in new eclipse. It worked.

No it is not efficient.

Answer 2

Check this version:

<web-app version="**2.5**" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_**2_5**.xsd" metadata-complete="true">

and 

org.eclipse.wst.common.project.facet.core.xml

<installed facet="jst.web" version="**2.5**"/>

It can be incompatible with the chosen server. In my case when I tried to upgrade 3.0 tomcat 6.0 stopped working so I had to revert back to 2.5


so upgrade your server to a highter version or downgrade the web.xml version and run maven --> update project and try again

Answer 3

I have the exact same problem and exact exception, but I solved the problem just by specify package type of POM to war like "war" and right click the project and select 'Maven > Update Project Configuration', then re-deploy that web module to tomcat server, that's it!
