Functionality of WAS

Functionality of WAS

WebSphere Application Server supports asynchronous messaging through the use of a JMS provider and its related messaging system.(JMS 1.1 Messaging Provider)

WebSphere Application Server provides authentication and authorization capabilities to secure administrative functions and applications, using LDAP

WebSphere Application Server works with a Web server (such as the IBM HTTP Server) to route requests from browsers to the applications that run in WebSphere Application Server. Web server plug-ins are provided for installation with supported Web browsers. The plug-ins direct requests to the appropriate application server and perform workload balancing among servers in a cluster.

Web services enable businesses to connect applications to other business applications, deliver business functions to a broader set of clients and partners, interact with marketplaces more efficiently, and create new business models dynamically.

Delivers a high performance and extremely scalable transaction engine for dynamic e-business applications
