Here is the example (based on the samples : calculator-rmi-service and calculator-rmi-references) and the exception seen from the client :
3 + 2=5.0
3 - 2=1.0
3 * 2=6.0
3 / 2=1.5

> Exception and RMI binding : propagating an exception.
> ------------------------------------------------------
>
> Key: TUSCANY-2545
> URL: https://issues.apache.org/jira/browse/TUSCANY-2545
> Project: Tuscany
> Issue Type: Bug
> Affects Versions: Java-SCA-1.3
> Environment: Windows 2000; JDK 1.6_05 or JDK 1.5_015, Maven 2.0.9
> Reporter: tomas darbois
> Attachments: calculator-exception.rar
>
>
> Let's say we have a Calculator.
> The client connects through SCA and binding RMI to the calculator. The calculator connects to the "divider" through SCA and binding RMI.
> The divider raise a ZeroException (an exception that is declared as being thrown by divide method, exception known only by Calculator and Divider ) he found that he has the divisor = 0 and didn't try to do the computation and instead throws this exception.
> Calculator catches the exception and raise a new exception ServiceFatalException known by Client and Calculator (code = << throw new ServiceFatalException( "A string message", e); >> where e is the ZeroException that has been caught).
> Client is trying to catch the exception ServiceFatalException.
> This architecture is failing because the RMI binding in client part tries to find the class "ZeroException" that is not defined in that environment.
> In case we add in the classpath the class ZeroException, he successfully recovers a ServiceFatalException.
> I'm joining an example containing the 3 elements (the 2 standalone server and the client).
