Seam is a powerful open source development platform for building rich Internet applications in Java. Seam integrates technologies such as Asynchronous JavaScript and XML (AJAX), JavaServer Faces (JSF), Java Persistence (JPA), Enterprise Java Beans (EJB 3.0) and Business Process Management (BPM) into a unified full-stack solution, complete with sophisticated tooling.

Seam has been designed from the ground up to eliminate complexity at both architecture and API levels. It enables developers to assemble complex web applications using simple annotated Java classes, a rich set of UI components, and very little XML. Seam's unique support for conversations and declarative state management can introduce a more sophisticated user experience while at the same time eliminating common bugs found in traditional web applications.

Seam is licensed under the terms of the LGPL. Full commercial support is available. Eclipse-based tooling for Seam applications is provided by JBoss Tools.

Reinvesting in Java EE

Seam is based on the Java EE platform. That's why reinvestment in Java EE standards is crucial to Seam's future. Many ideas which originated in the Seam ecosystem are being contributed back to the Java EE specification by Red Hat, being refined in the process. The most notable initiative is JSR-299: Java Context and Dependency Injection. This website is home of the reference implementation, Weld. Check out the development page to get involved. The Seam community also has lots of ideas for JSF 2.0 and JSF 2.1, so check out those pages to keep up with the proposals.
