You can get the VersionedPortletApplicationManager in the post release  
branch of 2.1.3 (2.1.4 trunk):

http://svn.apache.org/repos/asf/portals/jetspeed-2/portal/branches/JETSPEED-2.1.3-POSTRELEASE

Since this is not a final release, you will need to build it

Regarding class loader, make sure to put the class loader as  
documented on the Websphere deploy guide:

On General Properties, set Class loader order to Classes loaded with  
parent class loader last:

There is some end-user documentation here on the Desktop:

http://portals.apache.org/jetspeed-2/usersguide/desktop.html

A new PSML page is not always created per user. You can configure your  
system with either shared pages or unique home pages per user. The  
base Jetspeed demo has a combination actually. It would be a resource  
saving feature to only create new pages on customization.
