The extended version
In parallel, Cyberlab has also developed an extension to the standard version. This new solution
opens up for easy integration of CORBA and RMI/IIP solutions. This will give greater flexibility for
alternative solutions of the Lab Server SW. In addition, a very nice feature with this design is that
all the existing Providers using the old (but definitely not outdated) Java RMI solution will continue
working without any modifications whatsoever.
The new addition to the middleware solution is currently under testing.

The extended middleware solution
The double lines marked JRMP (Java Remote Method Protocol) and IIOP (Internet Inter-ORB
Protocol) is the separation between server and provider software. Everything below these lines is
part of the provider software and hence situated on the provider computers.
Below are some notes regarding the various components in the extended middleware solution

Cyberlab Server
The server can handle communication over different protocols such as JRMP and IIOP.
Dispatcher I – RMI
This represents a dispatcher object registered with the Cyberlab Server. The object enables
RMI (Remote Method Invocation) communication between software written in the Java
programming language. This dispatcher is part of the standard solution, and is still is part of the
