Qtracker is a server browser you can use outside of JA. You can get it here.
There's screenshots, forums, and all that other jazz you can use to get familiar with the software. Once you have Qtracker you're able to created something called a filter - which lets you narrow down the search you're performing for specific pings, max players, passwords, or even JA mods.
Download this filter ojp filter
and extract it into your root Qtracker folder. It should end up in Qtracker>Filters>Game>Jedi Knight Jedi Academy>Mods. Run Qtracker and on the right under the filters column there's a few tabs - one looks like a speaker. That's the game filters and under there is the JA>MODS/OJP filter you just installed. Get all the servers loaded by doing a find internet games on JA then click the checkmark and Qtracker will show you only the ojp servers. It'll even open and run ja w/ ojp if you connect to a server this way.
