Check out org.apache.jetspeed.portal.portlets.FileServerPortlet
This is exactly what it does however it also:
- allows you to define from XML what URL to spit out.
- Buffers the URL that you specified within a persistent disk cache so
if the URL is remote it doesn't refetch it everytime.
- Caches the Portlet after it was generated so that it can use the
in-memory version instead of doing a lot of work to rebuild itself.
Also, don't use StringElement for spitting out a file as it will escape
some of your characters. Use ClearElement that is in the JetSpeed dist
and is also in the ECS that is in CVS.

Especially the portlet API and some of the Portlet developer docs.
