RE: Jetspeed performance [was RE: master detail records displaye
d in a portlet]
Hi Meghan,
File based as in how?
The goal is to have JMX/MBean UIs be as simple and straight forward as possible. There will still a jetspeed.properties file for configuring all the basic service stuff and what not.
One of the major goals is to make deploying and using Jetspeed 2 as painless as possible
