I was trying to get JM-234 working on the latest nightly build, but I can’'t seem to get it to work. I have tried using just the hostname, hostname:9090, etc…
The jira spec was used as a base for the implementation but the final functionality is described better in the readme.html. However, we are now making some enhancements so the latest code in CVS and the readme.html are not 100% in synch. Anyway, if you are using the beta2 then you can follow the readme.html to learn how to use the servlet.
Once we consider the work done with the plugin we are going to update the plugins page so it would be easier to download and use the new presence servlet.
