Catching erros in web services

[Geoff O]

I have a try catch block in a web service that executes ADO.NET code that
interfaces with an Oracle database. In addition, I have a try catch block in
the client around the call to the web service. I am having an issue catching
the Oracle error and passing the error info to the client. When stepping
through the debugger, I have noticed that as soon as I step into the catch
block on the web service, the debugger jumps to the catch block on the client
and the client catch block is what is run. The issue is that code in the
catch block in the webservice does not execute. This causes the records
involved with the transacation to remain locked. Also, the Exception object
on the client contains SOAP error details, where as the Exception object on
the web service contains the Oracle error. I would like to access the
Exception object on the web service to be able to report the Oracle error
which is much more beneficial in reporting what the problem is. Does anyone
know what I need to do to access the Exception object info on the web
service?

I am using a C# Windows application as the test client. The web service was
written in C#. I am developing the web service on my localhost.

Below is sample code related to what I am currently doing:

Client Code:

try
{
errorMessage = webService1.DoS omething( param1 );
}

catch ( Exception ex ) // This exception obj contains SOAP error details
{
MessageBox.Show (errorMessage + " " + ex.ToString());
return;
}

Web Service Code:

try
{
dataAdaptor1.Up date(ds);
}

catch (Exception ex ) // This exception object contains the ADO/Oracle
error details
{
errorMessage = ex.ToString()); // As soon as I step here, the
debugger
// jumps to the
catch block in the client and
// none of this code
is executed causing the
// record in the
database to remain locked.
trans.Rollback( );
dataAdaptor1.Up dateCommand.Con nection.Close() ;
return errorMessage;
}
}

Please disregard this question.

I had a syntactical issue with a string.Format() statement that was the
first statement in the web service catch block. This made it appear to me
that the .net framework was automatically jumping to the client catch block
when in fact it was a second exception within the web service catch block
that was being thrown.

Problem solved!
