User exceptions for AMI?

[jharriot]

Hi,

Configuration: Ice=3.3.1, VS2009, WinXP, Language C#

I have created a user exception in the Ice file.

exception TickError;
["ami"] void Tick() throws TickError;

The server side code throws a TickError exception and the argument for TickError is a custom .net exception


void Tick(Ice.Current current__)
{
try
{
... blah

throw new CustomException("My message");

... blah
}
catch (CustomException ex)
{
throw new TickError(ex);
}
}

The client side implements the ice_exception(Ice.Exception ex) method. However I cannot obtain the message that was used to create CustomException. The Message field of the exception received by ice_exception() contains the type of message, eg ex.Message = SDS.Slice.TickError.

I modified the Ice async example code and the following approach appears to work.

Slice file:

exception RequestCanceledException
{
   string reason;
}

Server side:

entry.cb.ice_exception(new RequestCanceledException("hi there"));

Client side:

public override void ice_exception(Ice.Exception ex)
{
      try
      {
          throw ex;
      }
      catch (RequestCanceledException ex1)
      {
           Console.Error.WriteLine("Error: {0}", ex1.reason);
      }
}
