Someone has had some experience with the integration of Alfresco and jboss portal, more specifically, using webscripts of Alfresco as jboss portal portlets.
Someone who can share their experiences and some data for those like me (novice) we can make this integration.
The MySpaces webscript was written in a way that is to some extent tailored to working with Alfresco's out of the box webscript portlet class. This means that Alfresco would need to be deployed in the same app server running JBoss Portal.
We have made changes to this webscript to make it work with AWPr and called it AWPrMySpaces. You can download the AMP containing this webscript and another sample WhatsNew webscript here:
Also please be advised that we are planning on releasing version 1.1.0 of AWPr which will have a lot of new nice features that will make it usable with more webscripts.
