I believe what you are referring to as persistence is how the PSML pages are
retrieved....
see javadocs for the PSML Manager:

http://www.bluesunrise.com/jetspeed-docs/javadocs/org/apache/jetspeed/servic
es/psmlmanager/PsmlManagerService.html

The PSMLManager has 2 implementations, the default is file-based, the second
stores PSML in the database.
You can configure the PSMLManager in the JetspeedResources.properties

The Profiler services figures out which PSML page to request from the
PSMLManager based on requests params:
- media-type
-  user
- language
- countrycode

The profiler will also look for request parameters to specific pages, see
the /proposals/0005.txt in the cvs for details.
The Profiler sends a ProfilerLocator the PSMLManager, which is a
implementation-nuetral description of the requested profile.
The PSMLManager takes this and the tries to find the best resource to return
based on an internal fallback algorithm, searching thru its collection of
profiles(PSML) stored in the database or on the file system.
Profiler interface:
