On Tuesday 25 May 2010, Donald W. Long elucidated thus:

I found that if the service returns a string value and the service
throws an exception i can look at the result and it will contain
'soap:Server', but if the service returns void then you can not tell
if you have an error or not.


But what I am really trying to figure out, is how do you see what
exception the service has thrown.

You may noticed that I am using the WindowsHttpAuthenticated, this is
required for access to the server that is running the web services.

If you are not seeing a suds.WebFault raised then the service is not
raising a SOAPFault, and thus is returning error information to you
other ways. If the service does not raise a SOAPFault on errors, then
you will have to wrap the call and raise an exception if an error
condition is returned.

 

I understand the above but we did a test with C#, below is some of the code and we get a soap error.

 

 

public partial class _Default : System.Web.UI.page

{

    protected void Page_load(object sender, EventArgs e)

    {

        SAWebServices ws = new SAWebService();

        try

        {

            ws.GetBuildLocation(string.Empty);

        }

        catch (SoapException se)

        {

            Response.Write(se.Detail);

        }

    }

}

 

the above code will get a SoapException if an empty string is sent to GetBuildLocation.  The service is written in .NET ASP.  From what I have been told, Microsoft always converts the exception into a Soap Exception.  When we also use perl we get an exception for the client code but not using python and suds.  Should the SoapException be something else?

 

We are at a loss on this one and not sure how to continue using suds with Python.  Given all other languages that we use, C# and perl we get an exception from it.  With Python and suds we only get a string that says Soap:Server. 

 

What type of exception should we throw for the web service, and what I do not understand is given all these other languages and packages work, what is the difference between suds and what they are doing.  Most of the developers in my area feel that suds is not handling exceptions correctly, me, I am not sure, I am new at soap.

 

If you have any recommendations on what we should do then please let us know.  We would really like to move to Python and suds.

 

Have a nice day
