Today’s businesses implement numerous applications spanning the organization and multiple lines of business, and portals play an important role in integrating applications and providing a single, consolidated view for end-users. Industry standards such as JSR 168 and WSRP make it possible for an increasing number of applications to be accessible via a portal, increase developer productivity and significantly reduce development costs.
The preview release of Oracle’s tools supporting JSR 168 and WSRP standards include:
—Portlet Container for Java: A container that implements the JSR 168 APIs, allowing developers to build interoperable portlets using Java code; and
—Portlet Wizard for Java: An Oracle JDeveloper extension, which provides a wizard-based user interface that quickly defines various characteristics of a portlet such as display modes, customization, translation, security, initialization and caching.
Additional portal development resources are available in the Portal Developer Kit, which includes documentation and more than 15 code samples of JSR 168-compliant portlets running in WSRP containers.
Develop Portlets Just Once
Prior to the introduction of JSR 168 and WSRP, developers created portlets using proprietary APIs for a single portal platform—requiring a lot of time and greatly limiting the number of portlets available to other portal platforms. For example, developers and portlet resellers who built portlets for one platform had to rebuild the same portlet for each portal platform they supported. JSR 168 and WSRP ensure interoperability among different portal platforms, enabling developers and portlet resellers to build their portlets once with confidence that they will run in all portals that support the standards. The JSR 168 specification defines a standard application programming interface (API) for aggregating several content sources and front-end applications into a single portal. The WSRP standard enables portals to consume portlets from remote locations. Compatible and complementary to each other, the standards enable portal components to be deployed across any platform.
“As a member of the Expert Community of the Java Community Process for JSR 168 and the standards committee for WSRP, Oracle continues to demonstrate its commitment to open standards,” said Robert Lerner, senior analyst, Current Analysis. “These tools enable developers to run and test the interoperability of their Web-based content and applications with the latest interoperability standards, including WSRP and JSR 168.”
“JSR 168 and WSRP define a standard way to integrate portlets into a Web- based application,” said Marco Tilli, vice president of portal and hosted tools at Oracle Corp. “Our new portlet development and testing tools will help developers deliver applications and content to a wider audience, making it easier for our customers to build and maintain their enterprise portals.”
