Posted By:      Posted Date: October 08, 2010    Points: 0   Category :SharePoint

We are developing ASP.NET web application that interacts with SharePoint via web services. At some our customers' systems we encountered the following problem.
Web method GetListItems throws an exception :

PUT method gives error 400 "Bad Request" in WCF REST Service Application

I am trying to learn WCF REST Services through http://blogs.msdn.com/endpoint/archive/2010/01/14/updating-state-in-wcf-webhttp-services.aspx , It's a link of Part 3 of 12 part blog series. Now I am trying the same stuff given in the part 3 with my own Entities and Entity Model instead of what is given in the blog.

Error during execution a web method for a web service task - SSIS 2005



I'm created a SSIS 2005 pkg that refers a wsdl file by a web service task. When I execute the task I can see an error as

"Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: cannot possible to find the method 'ProxyNamespace.CreateAndCompleteSubscriptionImplService.action'..    in Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection)    in Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser)    in Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()"

I haven't written the wsdl file, but I must use it to use the web service in SSIS environment.

Any suggests to me, please? Many thanks


I can add that the web service is implemented with Java technology and the same wsdl it is used with success inside a .NET application. Thanks

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>

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

"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

Error Consuming Web Service - Unable to import binding xxx from namespace ...


In VS2008 / C# / ASP.NET 3.5, I wrote a test web service app. Here is an extract from the code:

I then created a test web application in VS2008 (named WebSvcTe

Cash Drawer - Method Open threw an exception - Windows Service

Hi All, I'm getting the following exception while calling Open method of Cash Drawer object. Method Open threw an exception.  Could not read the device name key's default value, or could not convert the Programmatic ID it holds into a valid Class ID. Code:   class Class1 { CashDrawer _uniCashDrawer1 = null; DeviceInfo cashDrawerDevice1 = null; PosExplorer posExplorer = new Microsoft.PointOfService.PosExplorer();   public void ClaimCashDrawer() { cashDrawerDevice1 = posExplorer.GetDevice("CashDrawer", "testDrawer"); if (cashDrawerDevice1 != null) { _uniCashDrawer1 = posExplorer.CreateInstance(cashDrawerDevice1) as CashDrawer; if (_uniCashDrawer1 != null) { _uniCashDrawer1.StatusUpdateEvent += new StatusUpdateEventHandler(UniCashDrawer1_StatusUpdateEvent); _uniCashDrawer1.Open(); _uniCashDrawer1.Claim(0); _uniCashDrawer1.DeviceEnabled = true; } } } }   Tha above code works fine if you put the code in WindowsApplication in all POS systems. The same is working if you put the code in Windows Service in all other POS systems. The same is not working if you put the code in Windows Service in Aures Galeo POS systems.  Thanks in advance.
