what can ?

some incompatible changes have been made in recent jdk versions cause old rmi tutorials not work. in particular, jdk 7u21 requires set codebase property on client , registry on server. screencast shows setting on server.

the screencast (or perhaps eclipse plugin) out of date in shows generation of stubs. it's not necessary use tool such rmic or eclipse plugin generate stubs, since stubs have been generated automatically rmi since java se 5 (which released in 2002).
