Domain management
JBoss AS 7 can be launched in two different modes. Domain mode allows you to run and manage a multi-server topology. Standalone mode runs a single server instance, a convenience choice for development. Many settings, such as port offsets and network interfaces, can be controlled with a single attribute. Rolling deployments are available.
Modular core
JBoss Modules offers true application isolation, hiding server implementation classes and only loads the classes your application needs. Class loading is concurrent for extreme performance. OSGi support is available the moment you install the application server.
First class components
JBoss AS builds on many best of breed standalone OSS projects: Hibernate, JBoss Transactions, Infinispan, Iron Jacamar, RESTEasy, Weld, HornetQ, JGroups, JBoss Logging, Mojarra, Apache CXF, and more.
Hot, incremental deployment
Quick turnaround during development as a result of fast, concurrent deployment and the ability to edit static resources without redeployment in a flexible deployment structure.
