I am bidding because I am already working with Jetspeed 2, portlets, JSR-168, WSRP, Pluto, OpenSourceCRM, Compiere and OFBiz (with Eclipse, Maven).
I am reluctant to bid because I can't demo and doubt anybody else can show you JS2 running on a production site. JS2 is only alpha state now.
I have Jetspeed 1.5 (and WebLogic) intranet sites with WS/EJB portlets.
You are probably smart to pull this offer and change to the eXo project that you have now posted.
eXo will get your job done today, though JS2 will be better later this year. It has the wizards, tools, doc and userbase. JS2 with cornerstone has a better framework.
I will not be bidding on the eXo portlet project, since I have no direct advert service experience. I do have years of eLearning, author-editor-prod workflow, XML/XSL/DTD, J2EE/J2ME, JSP, SQL experience.
I'd love to work on this project for you later, please keep me in mind.
