Tomcat: LifecycleException when deploying

I had this problem, where it just would not deploy on Tomcat , then i removed all @webServlet Annotations from all my servlet code and it deployed successfully.

This means something is wrong with your application configuration or startup.

There is always information about that in the logs - check logs/catalina.out and figure out what is wrong.

Remove the servlet-api.jar from build path and just add it on web-inf lib folder and then export the WAR file..it'll work...cheers..!!!
