you dont call _any_ methods on the bean. You call methods on its home interface, and
its component interfaces. So you call
myBeanHome.findByPrimaryKey(...)
the container then calls ejbFindByPRimaryKey(...)

it doesn't matter if its in the jvm or not... the container deals with that.
you should get a good ejb book, or read one online (see http://www.theserverside.com)
because this is basic ejb stuff, that you'd
learn a lot quicker from a book... also you might miss things learning this way.
