Everything was working fine one second and then my server started giving me this error. I went through all the answers mentioned here and what worked for me was this simple solution:

Deleting the server and then configuring a new one

If you're sure that you didn't change anything and the error just popped up, DO NOT start deleting .snap files or other temp files. Doing that will only cause more problems. And if the error occurred because of some changes made by you, this error is definitely going to be because of some errors in web.xml file.

P.S. Changing the workspace will do you absolutely no good, because if the problem is in your project, then it'll still occur in the new work space when you'll import the project!

I was facing similar problem this weekend  Tried all the above mentioned tricks  but none of them worked of me   Working in Eclipse LUNA   Then i analysed that just before creating a particular servlet  i was running Apache Tomcat v7 0 successfully  Which was  RefreshServlet  as shown below      So that practicing servlets to understand the  AutoRefresh  functioning  When i remove this servlet from my application  it works fine  but when i try to add and run this servlet  it gives the same error  Apache Tomcat v7 0 failed to start   Don t know why  but only removing this servlet works fine for me to run the rest of my application   So  the bottom line suggestion from me would be that if not any other trick is working  then try removing any latest servlet or any class you just created before getting this error and it may work fine for you too for the rest of the application   Any further explanation would be appreciated  Thanks

The problem could be annotations in your servlet s   see if you are using annotations for URL patterns for your servlets   Try to change the project facet  Dynamic web project    version to 2 5 and define all your servlet entries in web xml this should solve the issue   you can change project facet version in eclipse by changing it in project properties-- search for  facet  in the search box change the Dynamic web  project facet version to 2 5
