Dear JavaRanchers,

I am trying to implement a simple RMI application; It compiles successfully but I get an exception during execution. From the exception excerpt (see highlighted part in COMPLETE EXCEPTION below) it seems that the stub class(Iward.Hri.Remote.RemoteNotifyImplementation_Stub) is not found, but I did include its path in the classpath (so I guess the JVM should be able to find it).

I am not able to figure out the cause of this exception.

Could anyone please provide some input on this?

***IMPORTANT NOTE***
Please find below the exception during runtime as well as the actual code for your reference.

Also I have created the stub/skeleton as follows,
C:\>rmic -vcompat Iward.Hri.Remote.RemoteNotifyImplementation

and Stubs and skeletons are generated properly and included in the classpath

Kind regards,
Hardik Raja

    First of all, you don't need to generate stubs etc.. yourself. Which JDK are you using ?
