Getting issue "Service method name is not valid"

Hi All,

I couldn't be able to figure out the problem in the below case. I have a webmethod and calling the same using jquery ajax call. Below is the code.

[WebMethod(EnableSession = true)]
    [ScriptMethod()]
    public void SaveSearch(cnt strProp)
    {
    }

where cnt is the class.

When i calling this using ajax call like.

var strArray = {
                 cntName : "1",
                 cntEmail : "2",
                 cntMsg : "3"
            }

$.ajax({
               url: '/getproductsservice.asmx/SaveSearch',
               method: 'POST',
               data:  { strProp : strArray},
               contentType: 'application/json; charset=utf-8',
               success: function (data) {
                   var showMsg = ''
                   alert(showMsg);
               },
               error: function (data) {
                   alert('Save Search Failed');
               }
           });

When running this, i got the exception stating that "SaveSearch Service method name is not valid".

But if I replace the parameter with primitive data type like string or int it is working well. Problem is with the object types (list or object etc).

And if I use the primitive type, it is working only if the ajax content type is "content/xml" not working with "content/json". If I use the json type getting another exception of "An attempt was made to call the method \u0027SaveSearch\u0027 using a GET request, which
is not allowed."

Kindly help to resolve this.
