Webservice Exceptions Best Practices

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :.NET Framework

Hi guys,

I've a webservice that's being called from flex app. Currently I've a couple of exceptions being thrown from my web services. I'm designing exception scheme... what are common best practices on web service exceptions to throw from .asmx webservice? What exceptions should be considered from the web service?

I've  InternalSystemErrorException, InvalidInputException currently, but I believe there has to be more general webservice exceptions (as a best practice).

Any ideas?? best practices on web service exceptions?

In case there is an exception anywhere in the SharePoint 2010 project (most common place an exception would happen is during deployment of your SharePoint project, custom deployment configuration or custom deployment steps), there's a registry key EnableDiagnostics available for you to use.

saving XML output from webservice


 I created a webservice that takes casenum as input and gives results as a dataset in an XML.

I could make a web client to display the resulting dataset in a grid view. Pls see my code copied below.

Now I want to create a console client that takes the casenum as input, to call the webservice and saves the resulting xml for further processing, but can't figure out how to just capture the xml to save. Here's the code for my web client. I would appreciate if you could help modify this tocapture the resulting xml to save file locally.

Thank You.

namespace ResultsWebServicesClient
    public partial class _Default : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)

        private void BindDataToGrid(string CaseNum)
            FG_Results results = new FG_Results();
            DataSet ds1 = new DataSet();
            ds1 = results.Get_FG_Results(CaseNum);
            GridView1.AutoGenerateColumns = true;
            GridView1.DataSource = ds1.Tables[0];

        protected void GetResults(object sender, EventArgs e)


HTTP Post and WebService


I am working on a application which will accept the data in the post request. My application also wants to expose a web service and want to call another web service. Considering all these 3 action that I want to do, can I create a single application which will have a web form which will accept the POST request and expose a web service at the same time.

Although it may be possible to achieve this, Is this a correct way of doing it?

Calling webservice from the server


I have a sample web service and aspx file. I deployed them to an existing website that contains classic asp files.

web-service: --- using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; [WebService(Namespace = "http://localhost/MyWebServices/")] public class MembershipRegisWebService : System.Web.Services.WebService { public MembershipRegisWebService () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public string HelloWorld() { return "Hello World."; } }

aspx.cs file: --- using System; using System.Collections.Generic; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.Services; public partial class CallWebService : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { MembershipRegisWebService mrWs = new MembershipRegisWebService(); Response.Write("Calling web service:" + mrWs.HelloWorld()); } }

It runs locally, but it shows an error when running it from the server:

Server Error in '/' Application. Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the follow

C# / Java webservice


I am writting a client applicatin that acesses a webservice written by another company.  I need to test against this webservice but since it is live I need another place to test with.  I don't have access to the code from the webservice but have added a reference to my project.  I would like to create a test platform using C# which will run on IIS and not Java.

I have created a basic webserive using both the NetBeans platform and the VS/C# platform.  The problem I am having is if I dynamically change the web address from one to the other my client application complains that the webservice is invalid.  I have verified all the calls are the same.

Are there any setting with VS/C# that allow me to configure it to behave more like the Java webservice?  I don't have the server support to host the Java application for full testing along with other problems using the Java version.

I have run both services in the "WCF Test Client" and can see where the WCF service uses the varibles for request and the Java uses body/request but can't get the WCF to follow that format.  I read somewhere about changing the OperationContract with SoapRpcMethod but then the mentod is not longer exposed. I also tried a Web Service in .NET 3.5 instead of a WCF server but that seems to be more trouble and does not

Printing crystal report from webservice



I am trying to print crystal repot directly from a C# application, which is calling webservice. I am able to display report in crystalreportviewer by passing the webservice call to datasource. However, is there anyway, I can print directly without showing the report?

Alternatively, I was trying return ReportDocument object from webservice, which would solve my problem, but I was unable to return the ReportDocument because of serialization issue. Is it even possible? Thank you

Handling external C++ exceptions


Hi. I'm working in a application that uses an external .Dll developed in C++ language. According the business rule, the .Dll can throws one exception if it found a error. My question is if it's possible handle or catch a exception throwed by the C++ dll? The try/catch doesn't works. Bellow there's the code I'm using to call the C++ dll.

        public extern static IntPtr LoadLibrary(string lpLibFileName);

        [DllImport("kernel32", CharSet = CharSet.Ansi)]
        public extern static IntPtr GetProcAddress(IntPtr hLibModule, string procName);

        public extern static bool FreeLibrary(IntPtr hLibModule);

        private delegate void DllMethodCallBack(string param1, string param2);

        public void CallDllMethod(string param1, string param2)
