Answer 1

Just adding to existing answers. I was facing this issue with tomcat in eclipse. I had changed one class and did following steps,

1. Cleaned and built the project in eclpise

2. mvn clean install

3. Restarted tomcat

Still I was facing same error. Then I cleaned tomcat, cleaned tomcat working directory and restarted server and my issue is gone. Hope this helps someone
