RE: [Lportal-development] RE: Portlets Framework

[Brian Chan <b...@brianchan.com>]

In addition, for Liferay, all of the portlets do access one struts action beforehand, so you can add custom classes that go through the pre service and post service, but this is specific to Liferay and goes beyond the spec.

Remember, a JSR-168 compliant portal supports portlet applications as
indivdual web apps deployed to the respective servlet container, this a
requirement of the spec. Hence, you can use servlet filters within
individual portlet apps to attain the filter functionallity required by each
indivdual portlet application and the portlets contained within.  It was
crucial to the spec that it leverage as much functionallity from the servlet
standard a possible so as to make portlet and servlet develop easy/similar
as possible.
