I have a small web app and I had put all the compiled classes of it (Not jar/war but simple .class files of all the classes) in /WEB-INF/classes/ folder of Tomcat. It was working fine without any issues.
Since I had to put/copy all the classes separately, I created a jar file of them using Ant and put that app.jar in /WEB-INF/lib/ folder. I also moved all the individual .class files from /WEB-INF/classes/ (to make sure they are not used by Tomcat). Then I restarted the Tomcat server and now I get HTTP STATUS 404.
Note that I left all the JSPs, web.xml etc as it was before. I just wanted to group all the .class files to a .jar to make my life easier.
Is there something else I need to do ?
