What you say? There's no management console with OC4J 9.0.4 standalone. Well yes, officially you are 100% correct. There is no supported management console for the 9.0.4 release.
But ....
With a little bit of configuration, you can get the prototype admin console we've been using to test out a few things on the server side, up and running for OC4J 9.0.4 standalone. It's basically the same thing as the OC4J Admin Console that's configured out of the box in the OC4J 10.0.3 Developer Preview we have available now on OTN.
