Search Web Service not working in SharePoint 2007

Hi,

I am trying to access the web service provided by sharepoint 2007 and use it in the ASP.NET application. I want to use the following Web Service.

http://localhost/_vti_bin/search.asmx

http://localhost/_vti_bin/spsearch.asmx

And while executing the code, following error is being thrown.

Server was unable to process request. > Attempted to perform an unauthorized operation.

Following is the code I am using to access the Web Service.

Imports

SPSSearch
Imports System.Data

Partial

Class _Default
Inherits System.Web.UI.Page

ProtectedSub Page_Load(ByVal senderAsObject,ByVal eAs System.EventArgs)HandlesMe.Load
Try

Dim keywordStringAsString ="Microsoft"
 Dim qXMLStringAsString ="<QueryPacket xmlns='urn:Microsoft.Search.Query'><Query><SupportedFormats><Format revision='1'>urn:Microsoft.Search.Response.Document:Document</Format></SupportedFormats><Context><QueryText language='en-US' type='STRING'>" + keywordString +"</QueryText></Context></Query></QueryPacket>"

Dim queryServiceAs QueryService =New QueryService()
queryService.Credentials = System.Net.CredentialCache.DefaultCredentials
Dim queryResultsAs DataSet =New DataSet

queryResults = queryService.QueryEx(qXMLString)

Catch exAs Exception

Response.Write(ex.Message.ToString())

EndTry

EndSub

End

Class

Please let me know, if you encounter similar errors.

Thanks

John

You should set the URL for the Queryservice object and set QueryService.PreAuthenticate=true

Please find the below code and change the queryService.Url if you'r conecting remote server.
Code:

//The string containing the keyword to use in the search
string keywordString = TextBox1.Text;
//The XML string containing the query request information
//for the Web service

string qXMLString = "<QueryPacket xmlns='urn:Microsoft.Search.Query'>" +
"<Query><SupportedFormats><Format revision='1'>" +
"urn:Microsoft.Search.Response.Document:Document</Format>" +
"</SupportedFormats><Context><QueryText language='en-US' type='STRING'>" +
keywordString + "</QueryText></Context></Query></QueryPacket>";

SPSearch.QueryService queryService = new SPSearch.QueryService();
queryService.Credentials = System.Net.CredentialCache.DefaultCredentials;
queryService.PreAuthenticate = true;
queryService.Url = "http://localhost/_vti_bin/spsearch.asmx";

System.Data.DataSet queryResults = queryService.QueryEx(qXMLString);
GridView1.DataSource = queryResults.Tables[0];
GridView1.DataBind();

Thanks&Regards,

Try to give custom credentials from a user who has sufficant rights on the WSS site.
use this code:
Dim queryService As QueryService = New QueryService()
queryService.Credentials = new System.Net.NetworkCredential()
queryService.Credentials.UserName = ConfigurationManager.AppSettings("WSSUser") 'Or username as string
queryService.Credentials.Password = ConfigurationManager.AppSettings("WSSPwd") 'Or pwd as string
queryService.Credentials.Domain = ConfigurationManager.AppSettings("WSSDom")
'Or domain as string

Then your authentication will succeed

Did you ever get this working. I have the same issue. I am running with an account that has sufficient permissions (administrator) so that is not the issue.

I had kind of similar issue. You can try two things:

1. Try to test this in a Kerberos environment.

2. In the environment where I had to deploy my web application that called search web service, when I used the same account for my web application's app pool as it was for Sharepoint application's app pool, the error disappeared.
