I do know that Oracle uses a command line tool called DCMCTL for
java related deployments. From JDeveloper (during remote deployment) this tool is executed on the server (known as "Remote DCM").
I've had occassions where I've had access to Oracle AS and have deployed an .ear from there with dcmctl (ex: soap.ear). But not a .war.
If you investigate dcmctl you'll probably get some answers.
