SPContext.Current is null in a web service under a sharepoint site

Question

I'm exposing a web service in a SharePoint site e.g. http://server/_vti_bin/subdir/mywebservice.asmx.

In the web service method, SPContext.Current appears to be null.

(Interestingly, I'm looking at an example in Chapter 5 of Inside Windows SharePoint Services 3.0 and they use SPContext.Current inside a web service!)

Any idea what am I missing? Thanks in advance.

Answer 1

Could you supply some more info and perhaps code samples?

Which specific object in SPContext.Current is null?

How do you obtain credentials for the web service?

what authentication are you using?

Answer 2

Also, where is it being called from?

Answer 3

Is it possible that your subdirectory is set up as a web application and is therefore operating in a different context?

Answer 4

How are you calling the webservice? Is this an ajax call from javascript/jquery? If yes, have you added the ScriptService attribute on the webservice class?

[System.Web.Scripts.Services.ScriptService]
public class SimpleWebService : System.Web.Services.WebService
{
    ...
    ...
}
