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.
