The Java Community Process (JCP) uses Java Specification Requests (JSRs) to define proposed specifications and technologies designed for the Java platform.

The Portlet Specifications aim at defining portlets that can be used by any JSR-168 (Portlet 1.0) or JSR-286 (Portlet 2.0) portlet container.

Most Java EE (Enterprise Edition) portals include at least one compliant portlet container, and GateIn 3.2 is no exception. In fact, GateIn 3.2 includes a container that supports both versions.

This chapter gives a brief overview of the Portlet Specifications, but portlet developers are strongly encouraged to read the JSR-286 Portlet Specification .

GateIn 3.2 is fully JSR-286 compliant. Any JSR-168 or JSR-286 portlet operates as it is mandated by the respective specifications inside the portal.
