Custom WCF Service (svc) gives address scheme error

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :WCF
 

Hi,

I'm reading a book by Sahil Malik on building solutions for SharePoint 2010 (from Apress).
One of the items explained is how to create a custom WCF service that can then be consumed in different scenarios (.NET app, silverlight, javascript).

I followed the steps as given in the book, but when I try to open the URL to the service, I get this error:

This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection.
Parameter name: item

I have to mention that when I added the mapped ISAPI folder to my VS project, it didn't create the project subfolder automatically and I accidently created my files (svc and web.config) on the root level of the ISAPI folder. I created the subfolder manually and moved these two files in the subfolder, but it doesn't seem to work. Maybe I overwrote something on the root of ISAPI ?

My web.config contains this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <system.serviceModel>
  <serviceHostingEnvir

A little background because I feel I have an out of the ordinary architecture in place and don't know if this is contributing to the problem. 

We have an existing ASP.net application that is undergoing expansion.  The new functionality is all written in Silverlight 4.  As part of that expansion I gutted all the old Linq to SQL and put Entity Framework 4 into place.  To do this I created a standard .net Class Library and added my edmx files there.  Naturally, the business entities created by this cannot be used in Silverlight.  So I created a Silverlight Class Library and added all the business entities to that Silverlight Class Library as linked files.  I changed the name space to be the same.

So I have the following assembly / namespaces

Company.Project.Dal.csproj / Company.Project.Entities (.net 4 class library)

Company.Project.Entities.csproj / Company.Project.Entities (SL4 class library)

With this architecture I was able to share my business entities with my SL enabled web services, my asp.net projects, my silverlight projects.  Really it's a beautiful thing.

Once this was done I added "message" classes to Company.Project.Dal and again shared them with the other entites using linked files.  These messages are things like MyObjectRequest; they are class

Invoking custom WCF service throws an Impersonation error from SQL

  
I've written a custom WCF service and hosted it in SharePoint. Accessing the MEX endpoint works fine. However, when I try to invoke the WCF service from my client code, I get the following error: 'A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - Either a required impersonation level was not provided, or the provided impersonation level is invalid.)'. This exception gets thrown even before my WCF service gets invoked. Attaching a debugger, I see the following stack trace associated with the exception: 00000000`0c2dd7d0 000007fe`e7589b95 System_Data_ni!System.Data.SqlClient.SqlConnection.OnError(System.Data.SqlClient.SqlException, Boolean)+0xd4 00000000`0c2dd810 000007fe`e7b7cd3b System_Data_ni!System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(System.Data.SqlClient.TdsParserStateObject)+0xf5 00000000`0c2dd870 000007fe`e758c4ee System_Data_ni!System.Data.SqlClient.TdsParserStateObject.WriteSni()+0x5f77ab 00000000`0c2dd8f0 000007fe`e758bf29 System_Data_ni!System.Data.SqlClient.TdsParserStateObject.ExecuteFlush()+0xae 00000000`0c2dd950 000007fe`e757a1c7 System_Data_ni!System.Data.SqlClient.TdsParser.TdsExecuteRPC(System.Data.SqlClient._SqlRPC[], Int32, Boolean, System.Data.Sql.SqlNotificationRequest, System.Data.SqlClient.TdsParserStateObject, Boolean)+0x1189 00000000`0c2ddbf

Web Service Return Custom Error Code

  

I'm trying to write a Web Service that will return several different error codes so the client can handle each error code individually (e.g. err=600 call funcA, err=700 call funcB, etc..).

My code below always returns "500" for the _statusCode (or get_statusCode). Am I doing this wrong? How do I get a Web Service to return custom error codes to the client (javascript)? Any info appreciated. Thanks.

Try

If IsNothing(Membership.GetUser(UserName.ToString.Trim)) Then

objReturnValue = New UserInfo(UserName.ToString.Trim, False)

Else

objReturnValue = Nothing

Err.Raise(vbObjectError + 601, "UserExists", UserName)

End If

error using a custom collection object in a WCF service

  

I'm relatively new to WCF but have gotten most of my service to work very well. I'm having one "strange" problem: My service makes use of several custom data types, and all of them work fine except for the custom collections. Note...I am NOT trying to pass a collection object to the client...I am simply trying to initalize and use it from the main service object. Here is an example:

<ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerSession)> _
Public Class User
    Implements IUser

    Public Memberships As new Memberships   ' this is the collection I am calling!

    Public Function countMemberships() as integer Implements IUser.countMemberships
         return Me.Memberships.count       'this returns an error! Object reference not set to an instance of the object...

    End Function 

End Class


' and here is my custom colection 

Public Class Memberships
    Inherits System.Collections.CollectionBase

    Public Sub Add(ByRef Membership As Membership)
        List.Add(Membership)
    End Sub

Custom Control Design-Time SiteMap Provider Error

  

Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

<siteMap>
      <providers>
        <clear/>
        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 
             siteMapFile="web.sitemap" 
             securityTrimmingEnabled="true"/>
      </providers>
    </s

Custom Control Design view error

  

Hi

I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'


This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.


Property Code Example:

public string Text
        {
            get
            {
                string ret = "";
                object obj = ViewState["Text"];
                if (obj != null)
                {
                    ret = obj.ToString();
                }
                return ret;
            }
            set
            {
                ViewState["Text"] = value;
            }
        }


I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it

Error Handling: Throwing Custom Exception Types from a Managed COM+ Server Application

  

Exception handling semantics in .NET are based on type, so you can create custom exceptions that have their own properties and methods. In .NET, exceptions are first-class citizens, and since they're the built-in error handling mechanism, all .NET-compliant languages must support exceptions. In addition, COM+ services are available to .NET code as Enterprise Services, so you can leverage exceptions in your Enterprise Services design.In this article the author describes custom exceptions, throwing exceptions across COM interop boundaries, and working with Enterprise Services.

"Your search cannot be completed because of a service error. Try ..."

  

i have a problem with search function where everytime i search any file/doc the error message "Your search cannot be completed because of a service error. Try your search again or contact your administrator for more information." occurred. I realized that there are items in central admin but it is "not available" in my site. I already follow several guides that had been provided in this forum but still the same. Even, i already create new SSP and configure the search scope, content source and also crawling. 

FYI, i used Microsoft Sharepoint 2007. 

Hope anyone could help me to solve this problem. Thanks.


RDL Rendering (500 Internal Server) Error at Sharepoint Integrated Reporting Service

  

I have a serious problem that cannot be solved by googling around the keywords below:
sharepoint, moss 2007, reporting service, ssrs 2008, rendering, internal server error, ....

The error is;

"An error occurred during client rendering. The remote server returned an error: (500) Internal Server Error. "

Everything is O.K.;

* When I render the report from the REPORTSERVER (http://localhost/ReportServer)
* When the reports are scheduled to be sent by the reporting service (planned via MOSS 2007) 

But if I open (render) the RDL file from the sharepoint REPORTS LIBRARY interface, all of the reports fail with that internal error message above. 

It is weird also that parametrized reports are displayed without errors although the parameters are queried from a sql dataset. But I got the error when rendering the report after I've chosen a parameter  and order "apply/report"...

Possible causes how I met that error may be;

After I have installed (then uninstalled) AJAX extensions
After I have re-configured IIS Web Service Extensions list items

Possible solution alternatives I've found;

I've found a solution on MSDN replying a similar issue with an ideal cause of the error but an evreka answer but no sol

Rejected by custom validation error & ItemAdding

  

Hi,

I believe this topic was discussed before in this forum, but I couldn't find it using the exact error I receive: "operation for file.doc was rejected by custom validation on the server"

When I try to add a new word document to my doc library, Word displays this error instead of my custom error message. I set properties.Cancel=true in ItemAdding of my EventHandler, because my validation fails. 

Is there any way to display user properties.ErrorMessage instead of this generic error message?

Regards.

strange web service error

  

 

I wrote a small little vb.net app that should connect to a MS search server 2010 web service.

 

I added the web reference, which worked fine, but whenever I run the code, I get this strange error:

 

Microsoft.Office.Server.Search.WebControls.SrhdcNoInternalUrlException

 

I Googled it, but found very little info on it.

Can anyone make sense of it?

Thanks!
