The JMatter framework (see http://jmatter.org/ ) is a modern, model-driven framework for constructing business applications. It leverages Swing, Hibernate, and Java WebStart. JMatter frees developers to work on their applications' business logic without getting mired in persitence or GUI work. Today software projects spend a disproportionate fraction of their development resources building generic scaffolding for business applications: login screens, authentication, CRUD, persistence, system navigation, mechanisms for performing queries, wizards, calendaring, etc.. JMatter is an open-source project, available under either GPL license and alternatively under a commercial license. This project was open-sourced in June of 2006.
