How can I do a RPC (Remote Procedure Call) in Visual Java?
If RMI is the only way, then how can I add the RMI-classes to Visual Java?

You can code your own low-level RPC interface using Java's socket mechanism if you have strong reasons for not using RMI or CORBA (for example you want to do very fine performance tuning on a socket level).

If you want to use RMI, just use it, it is part of JDK 1.1 (there is a tutorial on Javasoft's web site on how to use it). I am not sure what you mean by "Visual Java", but again you do not need to add anythong special to your Java environment to use RMI. (You need to use java.rmi package when creating remote classes and a tool which generates stubs and skeletons which is provided with JDK).

Let me know if I did not answer your question.

Hmm, I am not sure whether Microsoft supports RMI (they might not, check the documentation for Java SDK 2.0 in their homepage, I know that Internet Explorer 4.0 does not support it). You might be better off using JDK or Symantec Cafe which is based on JDK and certainly supports RMI.

Another comment, I don't think that you can simply add RMI classes to environment whuch does not support it. The RMI support might be build into the Java VM.

Symantec Cafe is not visual, but Visual Symantec Cafe is. They had just released version 2.0 of Visual Cafe which is a nice tool, supports JDK 1.1, JavaBeans and comes with huge set of visual controls.  Check them out at http://cafe.symantec.com.
You can also get reviews of VC in various Java magazines.

Is the Code that I've written in Microsoft Visual J++ compatible
with Visual Cafe?

Code is compatible unless you used Java features which are unique to Microsoft such as RNI (native interface) or J/Direct (if you don't know what they are, you are not using them). Moreover, the class files should also be compatible, between dofferent environmnets. If you are using AFC, you would have to take AFC classes along to use them with Visual Cafe.

JavaBeans is standard which allows to create component-based software using Java. Check the JavaBeans spec on http://java.sun.com
