Problem in Routing WCF Service call from another WCF Service

Posted By:      Posted Date: September 30, 2010    Points: 0   Category :WCF
 
Dear All,
           I have few WCF Services hosted on a remote machine which access my remote DB.
I call the services from my windows application and everything works like a charm.

           Now I want to make the above service calls from machines which will not have internet.
But they will be on LAN where atleast one PC will have a active internet connection.
So I created another WCF service which is hosted on a Windows service on the internet enabled machine. I've added all the service referance in the new service and any service withoute any parameters work fine.

           But when I try to send any data as parameter I get error

"There was an error while trying to serialize parameter http://tempuri.org/:obj. The InnerException message was 'Type 'Consume_Win_WPF_Service.LOginService.ClsMessage' with data contract name 'ClsMessage:http://schemas.datacontract.org/2004/07/LoginService' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.'.  Please see InnerException for more details."

Can anyone tell me what steps I should impliment to en

Problem to obtain client IP on web service

  

Friends,

I'm having problems to obtain the client IP on web service. Here's my scenario:

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP 10.0.2.50 and host name ServerTransaction.
Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on  ServerTransaction, with IP 10.0.2.51 and host name ServerApplication.
Many other computers on the local network (IPs: 10.0.2.80, 10.0.2.81, 10.0.2.82, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (10.0.2.51).

Any idea or tip?


Thanks and sorry for my bad english.


problem compiling web service

  

Using Visual Studio 2010.

I created a webservice GetDemographicData asmx, GetDemographicData asmx.cs and then used wsdl to create a proxy, then used csc.exe to create dll.

first time when I generate proxy, it looks and works fine, but when I make some changes to my webservice and regenerate proxy the following problems occur:

1.I lost the function: public DataSet Get_GetDemographicData(string CaseNum, int Version)
2. The namespace changed to my-labs

Why?? Please see my code below:

Problem with passing an Image as binary through web service

  

All

I have a web service that is accessed by a windows forms application and receives updates like facility name, address, image etc. Everything works fine except the image data is not being passed to the windows app. I am saving the images in database on both sides, so when I pull it from the server I use the following code

if (!reader.IsDBNull(floorPlanOrdinal))

facility.FloorPlan = (byte[])reader["FloorPlan"];

I can see the facility.FloorPlan Dimentions as 103840 when I debug this method which means that the data is pulled from the database fine.

On the forms side though the dimentions become 0, all other values pass fine except this. Here is the facility property in the web service on server side.

Problem Integration SQL Reporting Service 2005 and SharePoint 2007

  
Hello, I'm trying to make our SQL Reports available on our SharePoint report center. I have SQL 2005 (sp3) report server that resides on a different server than our SharePoint 2007 server. So in our SRS Configuration Tool, we changed the database mode for SharePoint integration (before, we only had it in native mode), so we created a new database for this SharePoint Integration type. Next, I installed the Report Server Add-in for SharePoint 2007 server and it was successful. However when configuring the Report Server, we got stuck at the step "Grant Database Access". For some reason we keep getting error message "Named instance not found" We already installed Service Pack 3 on the Report Server... I heard that the problem is because the mismatched version between the Report Server Add-in in SharePoint and the SQL RS version... but I don't think this is the case for us. Do we need to install WSS on our Report Server too?     Another question: We already integrate our Report Server with Microsoft Dynamics CRM 4.0. However I see that when the Report Server is in the SharePoint Integration mode, all the reports in CRM don't work (because Report Manager is no longer available in this mode). Do you think it would be the best practice to install a copy of Report Server instance in our SharePoint 2007 server? Thank you, greatly appreciate all your hel

problem rename sharepoint 2010 search service application admin database

  
Hi all, i have a problem that hopefully someone has an answer to.  i am not too familiar with sharepoint so please excuse my ignorance. we have sharepoint 2010 on a windows 2008r2 server.  everything seems to work fine.  but as you know, the default database names are horrendous.  i have managed to rename all of them, except for the "search service application" admin database. the default is: Search_Service_Application_DB_<guid> the other 2 databases (crawl and property) were renamed without a problem. we are following the article from technet on how to rename the search service admin db (http://technet.microsoft.com/en-nz/library/ff851878%28en-us%29.aspx).  it says to enter the following command: $searchapp | Set-SPEnterpriseSearchServiceApplication -DatabaseName "new database name" -DatabaseServer "dbserver" however, i get an error about identity being null.  no big deal, i add the -Identity switch and the name of my search service application.  but the real problem comes the error it throws:   Set-SPEnterpriseSearchServiceApplication : The requested database move was aborted as the associated search application is not paused. At line:1 char:54 + $searchapp | Set-SPEnterpriseSearchServiceApplication <<<<  -Identity "Search Service Application" -DatabaseName "ShareP

Problem With SharePoint Designer 2010 and the Search.asmx Web Service

  
I've created a web service datasource on a 2010 site using SharePoint Designer. When I try to make use of the datasource on a page I get the "The server returned a non-specific error when trying to get data from the data source..." message. The datasource connects to _vti_bin/search.asmx. I am using the QueryServiceSoap port and operation QueryX. I've tried various queryXml strings, including site & people searches using both SQL and keyword syntax. eg <?xml version="1.0" encoding="utf-8" ?><QueryPacket xmlns="urn:Microsoft.Search.Query" Revision="1000"><Query domain="QDomain"> <SupportedFormats><Format>urn:Microsoft.Search.Response.Document.Document</Format></SupportedFormats> <Context>   <QueryText language="en-US" type="MSSQLFT"><![CDATA[ SELECT Size, Rank, Path, Title, Description, Write, Filename, Description, Author FROM scope() WHERE CONTAINS ('"Lorum"') AND  ( ("SCOPE" = 'All Sites') )   ORDER BY "Rank" DESC ]]></QueryText> </Context> <Range><StartAt>1</StartAt><Count>20</Count></Range> <EnableStemming>false</EnableStemming> <TrimDuplicates>true</TrimDuplicates> <IgnoreAllNoiseQuery>true&l

Issues in GetItemDataSources web service call in 2008 Report Server R2

  
Hi, I'm using Reporting Services web services endpoint ReportService2005.asmx with 2008 report server R2 and I'm facing some issues in getting the data source names for a report definition using the GetItemDataSources web service. The problem is that the data source names returned are different from the names of the actual data sources on the report server. The report has the following data sources: 0 1 _0 _A Data Source And the names returned by the GetItemDataSources for 2008 report server R2 is: AutoGen_0 AutoGen_1 AutoGen__0 AutoGen__A Data_Source When I make the same calls using a 2005 report server, the names returned are the same as that in the report definition. To summarize, only numeric data source names are changed to "Autogen_<number>"(eg. Autogen_0), data source names beginning with "_" are changed to "Autogen_<data source name>"(eg. AutoGen__A)  and spaces are replaced by an "_".   What is the problem for the data source names returned for 2008 report server R2? Or has there been any change in the way in which report server stores the data source names? Thanks, Kulbhushan Singhal.  

Delgation via web service problem

  
Hi, I have an ASP.NET 2.0 web app which calls a one way web method on a web service. This web method contacts remote servers and pulls back config information to confirm the state of new server builds (config, settings etc) and inserts the collected data into a SQL database. The web app is supposed to pass through the callers kerberos ticket to the web service and then again to the newly built server which is being checked, all via impersonation and kerberos delegation using the calling users administrator privileges. The trouble is, I just can't get the web service to run under the callers context. I have the SPN's set up, delegation turned on in the active directory objects for the computer running the web app and service and the worker process domain user service account. I have windows authentication on and impersonation set to true in both the web app and service's web.config, integrated authentication in IIS, and IE settings are all ok. All has been checked out and passes the tests in DelegConfig, but it still won't work. Where am I going wrong? Thanks for any help!
