Tips for solving common difficulties in Struts Summary Building and maintaining enterprise applications is very difficult. Designing elegant and easily maintainable user interfaces for these applications can be the most daunting task of all.

J2EE Design Patterns

The term J2EE is tossed around a lot because it is a generic term that covers many areas of enterprise and distributed development.

For exactly this reason, it is important to take advantage of the most efficient and effective strategies for new development or the refactoring of existing projects. To keep up with the new developments, it is imperative that you aren't wasting time maintaining designs that have poor architecture or code that was poorly written.

Best practices to improve performance using Patterns in J2EE

Pattern is a solution to a recurring problem in a context. Once Pattern (solution) is developed from a recurring problem it can be reused without reinventing the solution again. Patterns are popularized by the classic book Design Patterns: Elements of Reusable Object-Oriented Software, by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, also called as GOF (Gang of Four) representing four authors who wrote that book. Specifically for J2EE problems and solutions, we have now Core J2EE Patterns, Best Practices and Design Strategies by Sun Java Center and EJB Design Patterns by TheServerSide.com.
