Program guide > (deprecated) Partitioning facility

Deprecated feature: The partitioning facility (WPF) feature is deprecated. You can configure partitioning with WebSphere eXtreme Scale.

A partitioned HTTP application

As with a partitioned Java™ 2 Platform Enterprise Edition (J2EE) application with the partitioning facility (WPF), each HTTP WPF application must also contain a partitioned stateless session bean (PSSB). This bean interacts with a HttpPartitionManager interface, which make requests of HTTP partitioning. An application may optionally contain one or more Web modules that may also use the HttpPartitionManager. A servlet (within a Web module) can register for WPF events such as the loading and unloading of partitions by the partitioning facility subsystem. For HTTP partitioning a single partition should only be active on a single application server within the cluster. Finally, in addition to the application.xml file that is contained in the META-INF directory of an enterprise application archive (EAR) file, an application can also specify partition information in a partitions.xml file.

This application is particularly useful if the Enterprise JavaBeans™ (EJB) container and servlet are collocated on the same application. Note that the enterprise bean client and Web client will be directed to the same target endpoint partition on the application server. This implies that partitions used jointly by IIOP and HTTP may only be active on a single application server within the cluster.
