I don t know about that specific SharePoint web service  but you can decorate a page method or a web service with  lt WebMethod   gt   in VB NET  to ensure that it serializes to JSON  You can probably just wrap the method that webservice asmx uses internally  in your own web service   Dave Ward has a nice walkthrough on this

I use this method as a wrapper so that I can send parameters  Also using the variables in the top of the method allows it to be minimized at a higher ratio and allows for some code reuse if making multiple similar calls   function InfoByDate sDate  eDate       var divToBeWorkedOn     AjaxPlaceHolder       var webMethod    http   MyWebService Web asmx GetInfoByDates       var parameters      sDate       sDate       eDate       eDate                ajax           type   POST           url  webMethod          data  parameters          contentType   application json  charset utf-8           dataType   json           success  function msg                  divToBeWorkedOn  html msg d                      error  function e                 divToBeWorkedOn  html  Unavailable                          I hope that helps   Please note that this requires the 3 5 framework to expose JSON webmethods that can be consumed in this manner
