javax.jnlp usage: setServiceManagerStub

[David Alex Lamb]

I've been looking into using javax.jnlp to get limited access to the client's
machine (without having to request full access). The few interfaces I've
looked at make sense, but I can't find anything that tells me how to get it
all going by passing an implementation of the appropriate interface to
ServiceManager.setServiceManagerStub.

Is there some introductory or tutorial document I'm missing?

May be it is a misunderstanding. Not you have to call
ServiceManager.setServiceManagerStub(...);
but JavaWebStart (or what ever JNLP implementation you have) itself
calls it once during startup.
To get it going, you in your application call something like
FileOpenService service = (FileOpenService)
ServiceManager.lookup("javax.jnlp.FileOpenService");
FileContents contents = service.openFileDialog(...);
and similarly for the other services.

Is there some introductory or tutorial document I'm missing?
