Edit a deployed application using tomcat server

Question

Last year I deployed an appliction on a Tomcat 8 Server. The application misses some functions and has to be updated. Unfortunately the Maven project made in Eclipse is lost. So the question is, is it possible to add functions in a deployed appliction?

I hope someone can help me!

Project specs: -Built in Eclipse IDE for JAVA EE Developers -JDK 7 -Deployed on Tomcat 8 server

Decompile the class file, add your function and replace it in war and redeploy. Here is a good java decompiler: http://www.showmycode.com/
