Hi,

WSAD does not support RMI directly. There are no wizards and no direct connection into RMIC or way of starting the RMI registry.

Thanks Kyle:
But How to run rmi program with WSAD indirectly? Or I have to export the program?
Peter

[Kyle Brown]

You can run the program within WSAD just by using the "Run" icon on your main class. But you'll have to start the rmiregistry externally (at the command line), and you'll have to run RMIC externally as well.

Hi, Kyle:
Thank you very much. Do you know the reason that WSAD does not support rmi directly?
Peter

[Kyle Brown]

Mainly because it's not a J2EE technology (RMI over IIOP is). We support creation of EJB's, which do *everything* that RMI could do, so wjy support the older, less flexible, more insecure version of the technology?

Thank you very much Kyle.
Many people are taking SCJD exam. To do the assignments, we need to use rmi, gui, stream (for reading/writing files). These seem to be old and not j2ee. Do you think these technologies useful?
Another question: I feel that visual editor doesn't help a lot to create GUI, I prefer to write code to create GUI. Maybe it is because I am not familiar with visual editor. What do you think?

Well, the thing is that all of those technologies are VERY useful, even within J2EE, with the exception of RMI. RMI has, to a great extent, been superceded by RMI and RMI-IIOP. It is because of the J2EE focus of WSAD that we do not provide direct support of RMI.
As for the visual editor -- no mere human should ever be responsible for having to master the intricacies of a GridBagLayout. That kind of thing is what the visual editor is good for.
