WCF framework. But, for those like me, that are working on some large-scale projects where we are still using some old technology this could be an interesting post. http://stackoverflow.com/questions/13256420/display-custom-error-message-in-web-service-for-infopath-client I was kind of surprised the first time I saw an exception being thrown from the ASP.NET Web Service and how it looked ugly when the error Message Box appeared on the Client application (GUI). The Exception.Message contained the internal Web Service stack. The server-side code looked like this: [WebMethod] public SomeResultObject SomeWebMethod() { try { http://www.agile-code.com/blog/asp-net-web-service-returning-properly-formatted-error-message/ /* code here */ } catch (Exception ex) { /* Some logging logic here...*/ throw; //this would simply throw an SoapException } } The first thing I tried was to throw my Exception, and not just re-throwing, but this was not helping at all as I soon realized that all the exceptions thrown by the SomeWebMethod() would be wrapped internally by the .NET framework, and the SoapException would be thrown instead. The first approach - Client side My first approach of solving this problem was then to change the Client (GUI) application and display a generic error message, no matter what has been thrown by the Web Service. Obviously this was a bad choice, as there were so many conditions and error messages that the end-user needed to know about. So, this approach would probably work for someone, but unfortunately didn't work for me: public void WebServiceCallMethod() { try { /* Calling the web service here */ } catch(SoapException exc) { MessageBox.Show("An error happened w
Web service error code reference The HTTP server generates standard web service errors when requests fail. These errors are assigned numbers consistent with protocol standards. The following are some typical errors that you may encounter: Number Name http://dcx.sybase.com/1200/en/dbprogramming/errors-http.html SOAP fault Description 301 Moved permanently Server The requested page has been permanently moved. https://msdn.microsoft.com/en-us/library/cc825588(v=bts.10).aspx The server automatically redirects the request to the new location. 304 Not Modified Server The server has decided, based on information in the request, that the requested data has not been modified since the last request and so it does not need to be sent again. 307 Temporary Redirect Server The requested page has been moved, but this web service change may not be permanent. The server automatically redirects the request to the new location. 400 Bad Request Client.BadRequest The HTTP request is incomplete or malformed. 401 Authorization Required Client.Authorization Authorization is required to use the service, but a valid user name and password were not supplied. 403 Forbidden Client.Forbidden You do not have permission to access the database. 404 Not Found Client.NotFound The named database is not running on the server, or in web service the named web service does not exist. 408 Request Timeout Server.RequestTimeout The maximum connection idle time was exceeded while receiving the request. 411 HTTP Length Required Client.LengthRequired The server requires that the client include a Content-Length specification in the request. This typically occurs when uploading data to the server. 413 Entity Too Large Server The request exceeds the maximum permitted size. 414 URI Too Large Server The length of the URI exceeds the maximum allowed length. 500 Internal Server Error Server An internal error occurred. The request could not be processed. 501 Not Implemented Server The HTTP request method is not GET, HEAD, or POST. 502 Bad Gateway Server The document requested resides on a third-party server and the server received an error from the third-party server. 503 Service Unavailable Server The number of connections exceeds the allowed maximum. Faults are returned to the client as SOAP faults as defined by the following the SOAP version 1.1 standards when a SOAP service fails: When an error in the application handling the request generates a SQLCODE, a SOAP Fault is returned with a faultcode of Client, possibly with a sub-category, such as Procedure. The faultstring element within the SOAP Fault is set to a detailed explanation of the error and a detail element contains the numeric SQLCODE
