Application Server Support in Portal Server

The Portal Server provides support for the following application servers to be used as the web application container, in addition to the Java^TM Web Server software:

• Sun Java^TM SystemApplication Server Enterprise Edition

• BEA WebLogic Server^TM Server 8.1 SP 2

• IBM WebSphere® Application Server 5.1

Portal Server runs in the context of a web application container, which can be either a web server or one of the application servers mentioned above, depending on your deployment.

Running Portal Server on an application server enables you to:

• Decouple the portal platform from the application server platform, allowing you to choose the best combination of Portal Server and application server for your organization

• Call Enterprise JavaBeans^TM architecture and other J2EE^TM technologies that run in the application server container

• Use application server clustering, which provides scalability and high availability

• Use session failover in clustering (currently available on BEA WebLogic Server andApplication Server Enterprise Edition)
