These applications "MEjbApp, __JWSappclients, __ejb_container_timer_app" are system applications. They are deployed when the domain/server starts up the first time after a fresh installation, and loaded on subsequent server start ups.
Look at the server.log after you start up server the first time, and see if there are any exceptions in the log.
I am not sure what you meant they are on your other system, what's your set up? Did you try to install the server on serveral systems?
