OGCE 2: Standard-Compliant Portlets

The OGCE is developing standard compliant portlet components that can be reused by multiple container providers. The JSR 168 Portlet Specification defines interoperability standards for portal containers. JSR 168 compliant portlets may be deployed in multiple vendor containers. The OGCE is developing the following tools for standard portlet containers:

OGCE 2 Release Features

Core Grid Portlets	A core suite of Grid portlets for proxy management, remote command execution, remote file management, and GPIR based information services.
Grid Programming Interfaces	High level grid programming interfaces using the Java CoG kit that shield portal developers from changes in underlying grid toolkit version.
JSR 168 Velocity Portlets	Support for Velocity and JSP-based portlets. OGCE Velocity portlet tools allow you to port Jetspeed-based portlets into JSR 168 containers.
Choose Your Portal	Integrated build and deploy tools compatible with open source containers such as uPortal and GridSphere. Apache Maven is our build tool of choice.
Portal-Independent Services	Inter-portlet communication tools that allow portlets to share data. OGCE portlets and portlet tools can run in any JSR 168 compliant portal, without relying on container-specific services.
Supplemental Portlet Downloads	The JSR 168 portlet framework supports modular extensions of OGCE capabilities through WAR file downloads. See JSR 168 Portlets on the left navigator for more downloads.
