New to Refactoring?

In case you are not familiar with refactoring, we highly recommend Martin Fowler's book: Refactoring: Improving the Design of Existing Code. In that book, Fowler provides many techniques (and catalog) for refactoring existing Java code to improve it. We adopted the same concept of refactoring, but apply it at a higher level of abstraction in J2EE.
