For future searchers, the built in page that appears when you just call the asmx page shows that the webservice requires a specially formatted xml text, with (in this case) json as one of the elements. –lowerkey Jan 28 '12 at 20:29 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote The problem is that ASMX web-service need to find all input parameters in the request. If at least one input parameter will be not found in the request to the server the web service failed with the status code 500 (Internal Server Error). The reason is that you send the data in the wrong way. The name of the input parameter of the web method is json (see void receiveOrder(string json)). So the data option of the $.ajax should be in the form data: JSON.stringify({json: webOrder}) if you use type: "POST" instead of data: JSON.stringify(webOrder) which yo

As the 500 internal server webservices is coded using .NET 3.5, I can't have that webservices on v1. Anyway, I assume I am supposed to make use of JSONP in this case, but each time I run the page, the ajax part does not work and in google chrome, I just get a 500 error message, as in cancelled. I can't figure out why this is happening. Here is the jQuery which is on the v1 .NET 1.1 server: function selectedDateTime(strDate, strHours, strMinutes) { $.ajax({ type: 'POST', url: 'http://intranetv2/webservices/meetingrooms.asmx/GetDayCount', data: '{ strMeetingDate:"' + strDate + " " + strHours + ":" + strMinutes + ":00" + '" }', contentType: 'application/json; charset=utf-8', dataType: 'jsonp', success: function(department) { alert("success"); }, error: function(xhr, status, error) { alert("error"); } }); return strDate + "---" + $("#txtDate").val(); } As you can see, I am trying to access an .asmx file on the v2 .NET 3.5 server. When I run this, google chrome gives me an 500 server error and says that the asmx file has been cancelled, and I then get an alert showing me the date alert at the

I used a default HelloWorld service created in VS studio. I am calling the service via jQuery like this: in Default.aspx: in TestService.asmx using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; namespace WebServiceTestWitJQuery { ///
