JSR-168 Portlets

Portlets function similarly to providers, however they are based on the API defined by the JSR-168 portlet specification.

The Sun Java System Portal Server includes the following sample portlets:

• Notepad Portlet

• JSPPortlet

• Bookmark Portlet

• Weather Portlet

Use the Portal Server management console of command-line utilities to deploy these portlets at the Enterprise Sample organization level.

The advantages to using portlets are as follows:

• Portability. A portlet implemented using only the standard Portlet API and other standard J2EE interfaces, is portable to any JSR168 portlet specification-compliant portlet container.

• Access to developers. As support for the portlet API grows with multiple vendor implementations, more developers are becoming familiar with the API.

• Developer tools. Wider support may be available for developer tools to create portlets.

• Web application integration. The portlet API is based on the Servlet API, making it is easier to integrate portlets with servlets and other standard web application components.
