Thanks goes out to all that were able to attend last night's JavaOne BOF, "Dynamic Portals and Ajax in Portlets".  There was lots of good open discussion about the challenges and successes of implementing new dynamic portals with AJAX.  The slides are available here.  Below is a list of resources URLs for some of the topics we discussed.  Check back here and at GregZ's blog for new developments regarding AJAX in portals and portlets.
    desc Continuing our contributions to developers.sun.com, a new article titled, "Building Mashup Portlets" is now available on the SDN Portal Server web site.  This article describes the procedure for building a sample Mashup Portlet by merging geospatial data with an AJAX-based mapping service, and for deploying the portlet to Sun Java System Portal Server 7.

 Also note other recent articles like:
1. Publishing JSR 168 Portlets as Remote Portlets With WSRP
2. Building IPC Portlets for Sun Java System Portal Server 7 With Sun Java Studio Creator 2
3. Creating Dynamically Generated Charts in Portlets
4. Asynchronous Rendering of Portlet Content With AJAX
