A collection of samples and reusable templates which demonstrates patterns, approaches and architectural ideas for the Java EE 6 platform. All projects are created with Netbeans 7 and tested on Glassfish v3 and partially on openEJB and JBoss 7. Check out also: http://java.net/projects/x-ray - an end-to-end Java EE 6 application.
What Is an AntiPattern? AntiPatterns, like their design pattern counterparts, define an industry vocabulary for the common defective processes and implementations within organizations. A higher-level vocabulary simplifies communication between software practitioners and enables concise description of higher-level concepts. An AntiPattern is a literary form that describes a commonly occurring solution to a problem that generates decidedly negative consequences. The AntiPattern may be the result of a manager or developer not knowing any better, not having sufficient knowledge or experience in solving a particular type of problem, or having applied a perfectly good pattern in the wrong context. AntiPatterns provide real-world experience in recognizing recurring problems in the software industry and provide a detailed remedy for the most common predicaments.
In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Uses of Design Patterns Design patterns can speed up the development process by providing tested, proven development paradigms.
