JSR 168 Portlet Catalog

From Wikipedia, the free encyclopedia

JSR 168 i.e. Java^TM Portlet Specification request is basically a standard to determine the development of portal components. This specification defines standard application programming interface for portlet development. The primary purpose of JSR 168 is to provide a standard programming model for creating portlets.

Portlets based on JSR 168 standards are known as JSR 168 portlets.

Initially portal vendors had their own portlet development framework thus those portlets were confined to specific portal servers and couldn't be deployed to the rest of the portals. After JSR 168 inception, portlets may be deployed on any portal servers adhering to JSR 168 specifications.

A Portlets Catalog is a set of portlets that are ready-to-use components for enterprise portals. For those who want to adopt portals certainly need many and variety of portlets to deploy and run. Here Portlets catalog are of use.

A JSR 168 portlets catalog makes sure that portlets under this catalog may run on any standards–compliant portal server. Types of portlet solution (vertical domains and technology) like collaboration, social networking, community, content management, utility, calendaring, HRM all are available in these catalogs.

There are many open source and commercial Portlets Catalog available but JSR 168 based solutions are rare.

JSR 168 specifications offer suitability to the developers to reuse the code to maintain a set of JSR 168 complaint portlets. For deployers, it’s easy to keep a single set of solution and deploy it on many.

SyncEx^TM, a known name in Portal Community, exhibits a range of JSR 168 compliant portlets.
