The social enabling of simple app doc, http://wikis.glassfish.org/socialsite/Wiki.jsp?page=SimpleApp,
works perfect if SocialSite was installed with AS_SERVER_NAME = localhost. But in typical user scenarios,
the AS_SERVER_NAME will be configured with some actual server name (say mymachine.sfbay.sun.com).
In this case, the user will have to user the actual server name configured for SocialSite rather than
localhost - specifically in the files that are given for download in section "Add SocialSite Features to the
Application" of the doc. If these files refer to localhost but the SocialSite instance was configured with
some actual host name, then the sample app wont show gadgets at all.
