Your trace shows you are using Catalina (aka Apache Tomcat). Sometimes Tomcat caches information in the "work" directory and it isn't always flushed. I recommend you stop the webapp, delete the appropriate "work" directory then restart your webapp to ensure any cached classes related to your webapp are gone. Again, this is under the "work" subdirectory not the "webapps" subdirectory where your application gets installed - different places.
