Harri has written up instructions on deploying blojsom on Orion J2EE Server. It seems a bit complex. Is there an easier way Orion folks?
If you look at the installation guides for Tomcat | JBoss | Resin | Jetty, the jist is this: download blojsom, deploy blojsom, and then blojsom is running. The Quickstart bundle makes deployment as straightforward as it could possibly be without the need for any configuration changes whatsoever.
In any event, chock another server up on our list.
Update: Joe Ottinger wrote up a much simpler set of instructions for installing blojsom under Orion here. Thanks!
