Design and Development of Java Code Generator Framework: Easily Extensible Java Code Generator

After many years of practice as software developer and system designer, I've always been missing a Java code generator, which at the same time: ? Generates a reasonable Java source code. ? Splits generated classes into three or more tiers. ? It gives you the freedom to override or extend the generated classes, when needed. ? It uses open source frameworks such as Spring, Hibernate, Seamframework etc. ? After entering one or more database tables the Web or Swing GUI is generated by a mouse click. ? It's easily extensible. ? It's implemented as an Eclipse plugin. With JSGF you can per mouse click within a few minutes generate a Web or Swing Java application. This allows avoiding from 60 to 80% resources.
