J2EE Design Pattern Samples

Design patterns are proven solutions to the recurring design problems. J2EE-specific design patterns identify the minimal set of known problems that an application architecture should solve. These patterns are based on experiences of the J2EE community and use J2EE technologies to solve problems. The advantages of applying a design pattern are: proven solutions to the problems, reusability, improved performance, increased maintainability, and so on.

This sample application code section will present a series of J2EE design patterns and their implementations in the real world. Bookmark this space and check back for new design pattern sample application code.
