I just started learning Java RMI and am having a problem getting my first
server up and running.

I am using JBuilder X Foundation on Win 98.  I have a project called Test
located at C:\ATest.  There are 3 source files in a package called test
located at C:\ATest\src\test.  The class files go to C:\ATest\classes\test.
The 3 source files are WeatherIntf.java  (the remote interface),
WeatherServer.java (the server program), and RMIdemo.java (the client
program).  (Yes, this is the example program from Peter van der Linden's
book Just Java.)

I build the project in JBuilder.  Then from a DOS window I run the rmic on
WeatherServer.class to generate the stub and skeletons (I don't see a way to
do this in JBuilder X Foundation).  These two files go to
C:\ATest\classes\test  (i.e same directory as all other classes in project).
I then start the RMIRegistry from Tools | RMIRegistry  in JBuilder.  I then
run WeatherServer from JBuilder using a runtime configuration set up with a
policy file that grants the required socket permissions (connect and
accept).

At this point I get the following error:

RemoteException occurred in server thread; nested exception is:
 java.rmi.UnmarshalException: error unmarshalling arguments; nested
exception is:
 java.lang.ClassNotFoundException: test.WeatherServer_Stub

In the output window in JBuilder I also see the following fragment along
with a list of other paths:
C:\JBUILDERX\JDK1.4\bin\javaw -classpath "C:\ATest\classes;".......

Since C:\ATest\classes is in the class path, I don't understand why
test.WeatherServer_Stub cannot be found.  It is in the very same directory.

Any help would be greatly appreciated.
Thanks
