None of the answers mentioned above worked for me  I am using Tomcat 9 in my Eclipse IDE  Hence I tried the following steps on my Eclipse Neon    Step  1  Click on Servers tab to see your server  In my case  it looks like the following     Step  2  Right click on the server  select Properties  you will see the following window  Click on Switch Location  it will change the location to the one shown in the image below from the default one Click on Apply and then OK to close the window     Step  3 Double click on the Tomcat Server which will open the Overview option as shown in the image below  The Server Locations part was active for me when I did  it s shown inactive in the image because I already did that at my end and I have my server running  that and I selected the second radio button option which is Use Tomcat installation  takes control of Tomcat installation   I then closed this option   saved the changes when prompted and started my server  It started working fine

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

open your web xml file   if you don t know where is it  then just google it   it is like this    lt  xml version  1 0  encoding  UTF-8   gt   lt web-app xmlns xsi  http   www w3 org 2001 XMLSchema-instance  xmlns  http   xmlns jcp org xml ns javaee  xsi schemaLocation  http   xmlns jcp org xml ns javaee http   xmlns jcp org xml ns javaee web-app 3 1 xsd  id  WebApp ID  version  3 1  gt           lt  web-app gt    just below the  lt  xml version  1 0  encoding  UTF-8   gt  line  add a tag  lt element gt  and close it in the very bottom with  lt  element gt  tag  Done

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
