Tangosol introduces a series of new capabilities in Tangosol Coherence designed to enhance applications running on BEA WebLogic Portal. Tangosol is the leading provider of data-grid and clustered caching solutions for large-scale Java and J2EE applications, and is leveraging its expertise in large-scale mission-critical applications to add Wide Area Network (WAN) clustering, clustered workflow and clustered caching to WebLogic Portal applications, including those federated using the new Web Services for Remote Portlets (WSRP) standard.

The Tangosol blueprint for clustered and federated portal data leverages WebLogic Portal's Custom Data Transfer extensions and Coherence's sophisticated partitioned clustered caching. Using the Tangosol blueprint, portal applications can efficiently share large amounts of workflow and live data in real time across any number of federated portlets, enabling complex applications to be assembled from an organization's own reusable portlets.

Common use cases for clustered and federated WSRP include online loan applications, which have to collect information over a series of pages, using a collection of domain-specific portlets, and online banking systems, in which portlets are all working with different views of the same user and account information.

"Many of our customers see a major opportunity in sharing workflow and live data across federated portals." said Alex Toussaint, BEA Product Manager for WebLogic Portal. "Our customers are building complex portal applications, and quite often they see opportunities for reusing individual portlets. These portlets may be developed independently, and may even be deployed into separate application clusters and datacenters. The same portlets are often applicable both to internal applications, such as those used within a call center, and to public-facing web sites, such as Internet banking.

In all of these cases, our customers can federate these portlets together using BEA WebLogic Portal with WSRP, and they can use Tangosol Coherence to efficiently share live data and documents-in-progress within these federated portals."

Starting with release 3.1, Coherence*Web includes WAN-capable HTTP session clustering support for WebLogic Portal applications. Coherence*Web is a module that provides HTTP session management for extreme-scale clusters requiring the highest levels of availability and scalable performance.
