Spring: Integrating iBATIS  iBATIS is one of the object-relational (OR) frameworks embraced by the Spring framework, and it's an ideal choice for those seeking a middle ground between full-blown OR and hand-written JDBC. In this excerpt from Spring: A Developer's Notebook, Bruce Tate and Justin Gehtland show how to integrate iBATIS with Spring.   [O'Reilly Network]

There Is No Open Source Community  Conventional wisdom argues that open source success is the result of individual iconoclasts who work against the economic grain to institute a methodology of sharing. That's nice--but it ignores strong economic trends that push open source development and adoption. John Mark Walker explains why the myth of the open source community is wrong and even harmful to business.   [ONLamp]

Hibernate Class Generation Using hbm2java  Hibernate uses mapping files to express the mapping of Java classes to database tables. In a complex project, keeping mappings in sync with your Java code can be burdensome and error-prone. Fortunately, the hbm2java tool can automate this by generating POJO classes from the mapping files. John Ferguson Smart shows how to use hbm2java with Ant and Maven, and how to customize the behavior of the generated classes.   [Java]

Through Project Looking Glass with Hideya Kawahara  3D has taken over video gaming. When will it take over mundane computing areas such as file managers, word processors, and desktop environments? Maybe soon, if Hideya Kawahara and the Project Looking Glass team have their way. John Littler explores the ideas, implementations, and possibilities of 3D interfaces in this interview.   [Linux]

Lightweight R/O Mapping  O/R frameworks map Java classes to database tables and SQL code. While popular, this approach is unpopular among DBAs, with the database at the mercy of an external tool. Another approach is to go the other direction: write tables and stored procedures and generate Java classes from that. Norbert Ehreke introduces Amber, a framework that embodies this approach.   [Java]
