Java Portal engine for integration

Question

I want to add a dashboard functionality to an existing java web application, this should be a portlet container, so it can host other mini applications or open social gadgets.

What is the best solution for this? Integrating an existing full blown portlet container?

Answer 1

Apache Pluto is an embeddable portlet server if you're looking for a simple engine to use existing portlets - it even has a JSP taglib you can use to embed in views.

You mentioned OpenSocial though (which I'd recommend over JSR-168, unless you have a particular portlet in mind) for which you could look at Apache Shindig, though that's still somewhat of a moving target.

Answer 2

Look at Liferay as a portal container:

The open source version is free, and there's an enterprise edition (if you feel the need).

Answer 3

Infopark has a JSR-168 Portlet Container delivering portlets anywhere in normal content. They do content management, so the portlets are a way to create personal dynamic parts in static content. It works as a webapp in any servlet container like tomcat 5.5. Sorry, but it is commercial software.
