And because the portal controls page layout, you can reposition and resize one or more portlets on a page without altering any portlet code. Even so, the advantages of modularity are so great that porrlet still recommend you develop your portlets as OSGi modules.

The third method mixes form submission and action request. For more information, see The XML configuration interface.

Packaging portlet classes, resources, and descriptive information in a single file makes distribution and deployment of portlets easier. Minimized A portlet may show very little information, or none at all.

2866 to the documentation for Rational Application Developer for complete setup instructions. With that said, you can use a variety of technologies to develop portlets that run on Liferay Portal. Therefore, the portal server copies was.

Edit Allows a user to customize the behavior of the portlet. In order to write a portlet using JSF a ‘bridge’ is needed. Once the portlet processes all events, the portal calls the Render phase on all portlets on the page.
