Using WebService from Microsoft Reporting Service(MSRS)

Question

Hi,
I want to invoke the web service from MSRS Report. Below is the details of my environment.
Web service is deployed on the local machine.
MS Report Server : SQL Server 2012 Reporting Service
Designer Tool Used : Visual Studio 2010
I have created a sample report in MSRS side, which should call getXXX, a web service method in XXXService(webService).
I created the datasource of Type "XML" in Visual Studio, and given connectionString
as "http://localhost:8080/axis2/services/XXXService".
I created the dataset in Visual Studio, using datasource in previous step and used the below Query
to pass the request to the WebService.
<Query>
   <Method Name="getXXX"
Namespace="http://localhost:8080/axis2/services/XXXService">
   </Method>
</Query>
or
<Query>
<SoapAction>http://localhost:8080/axis2/services/XXXService/getXXX</SoapAction>
</Query>
I am getting following exception in the Query Designer window.
===================================
An error occurred while executing the query.
Failed to execute web request for the specified URL.
Soap Fault:
The endpoint reference (EPR) for the Operation not found is http://localhost:8080/axis2/services/XXXService and the WSA Action = http://localhost:8080/axis2/services/XXXService/getXXX (Microsoft SQL Server Report Designer)

Please help me in figuring out the problem in the configuration done or query passed in the Dataset of Visual Studio/Report Server.

Hi Sridhar Singh,
According to your description, you created one web services and one web method, when you use it as data source, you got the error message.
To retrieve data from XML data source, the connection string must be a URL that points to the Web service, Web-based application, or XML document available through HTTP. XML documents must have the XML extension. The connection string syntax for a Web service
is http://servername /service.aspx.
In this case, please make sure that the web service is published successfully through url. Then we use the query like below:
<Query>
<Method Namespace=" http://localhost:8080/axis2/services/" Name="XXXService"></Method>
</Query>
In addition, the XML data processing extension does not detect the schema for us. Therefore, we must have some way of discovering which SOAP methods will retrieve the data that we want. The default SoapAction for the case is like below:
<Query>
<SoapAction>http://localhost:8080/axis2/services/XXXService</SoapAction>
</Query>
For more information about XML Connection Type, please refer to the following document:
