Red Hat announced the global availability of JBoss Enterprise Portal Platform 4.3, an integrated and standards-based open source platform for hosting and portal based applications and rich web presences. JBoss Enterprise Portal Platform 4.3 maintains its focus on enterprise needs with improved server performance, high availability, clustering, installation and configuration.

New features in JBoss Enterprise Portal Platform 4.3 include:

• Compliance with JSR-286 specification - JBoss Enterprise Portal Platform 4.3 fully supports the Portlet 2.0 (JSR-286) specification. This new standard facilitates a more dynamic user experience through improvements in portlet to portlet communication, caching support and handling of Ajax frameworks.
• JBoss Portlet Bridge - JBoss Enterprise Portal Platform 4.3 also introduces JBoss Portlet Bridge, an implementation of the JSR-301 specification, which supports JavaServer Faces (JSF) within a portlet and with added enhancements to support other web frameworks (such as Seam and RichFaces).
• Portlet tools - Red Hat will be including a new set of portlet plug-ins and wizards in the upcoming release of JBoss Developer Studio 2.0. These new plug-ins will make it easier to create and deploy portlets for both standard JSR-286 and Portlet Bridge-based portlets.

Designed to support a broad range of composite applications, from small departmental-focused mashups to enterprise-class site presences, JBoss Enterprise Portal Platform behaves like a no-license-fee-platform combined with a flexible and scalable underlying platform. Additionally, the JBoss Enterprise Portal Platform delivers high-value features without a large number of dependencies, allowing portal applications to be deployed quickly.
