Sorry that should be TomCat but I could not resist - took me back to the Saturday morning cartoons of my youth and Swap Shop ... heady daze of Marmite on toast for breakfast, a bit of Swap Shop with Noel Edmunds and then down the park for a game of footie with my mates for the afternoon. Then back home to watch the vidiprinter give the days football scores - I lived on the south coast but for some reason supported Leeds United . I think they were the team of the moment in the mid 70's with Jimmy Armfield and Tony Currie - I was a fickle fan! Apologies, probably lost most of the US based readership over the last paragraph.
The standalone server will deploy on TomCat and we do document the how but we quite rightly assume you have got TomCat running and the application manager installed. I have had some trouble getting TomCat setup in the first place to be able to deploy a war/ear file through their deployment interface. I have missing libraries and ant installs - its all too messy. Just give me an install that does everything out of the box without the need to go searching for libraries and supporting installs - maybe Im being lazy and too tough on Apache but, please make my life easier. Some of us really do not care about having choices - just give us Vanilla!
There is another method for getting the WAR deployed which worked great for me on 5.5.x - have not tested on 6.x yet. Take the xmlpserver war file and drop it into the 'webapps' directory and start the server or drop it in while the server is up and it will be deployed for you ... nice. OC4J is an Oracle product and just for once I think we have something over the competition (flame away guys) - you get a nice interface or command line to deploy your applications that works out of the box!
