SharePoint 2010 Webservice is alwayes returing XML

Question

I have a custom Sharepoint webservice returning array of obejcts. But when I call this webservice from JQuery it alwayes return XML.  When I set contentType as "application/json" the web service throws error saying "Unsupported media type".

I want array of objects back.  I have set [ScriptMethod(ResponseFormat = ResponseFormat.Json)] above my webmethod.

One more thing,  even if the webservice is getting executed successfully, always AjaxFailed() function is getting executed. The success function is never getting executed.

so two problems

1. How to return JSON ?

2. Why alwayes Ajax failed function is getting executed even if status says OK. ?

Code snippet is below.

Thanks much in advance.

Answer 1

Hi!

Did you try to specify content-type in request?

Content-Type: application/json

Hi

In the var wsUrl = "_vti_bin/DisclosureWebService.asmx ";  line

shouldn't you append the name of your webmethod ?

var wsUrl = "_vti_bin/DisclosureWebService.asmx/<name_of_method> ";

Answer 4

Yes I Did. If I specify application/json , the function throws error saying "Unsupported media type."

Answer 5

Yes I did add a webmethod name. Also the SOAP request has details. So even if I dont mention the webmethod name, the SOAP request takes care of that.

I removed the SoapREquest parameter and it started returning the Json object.
