javascript soap error calling asp.net web service

Question

I have a working ASP.Net test web service, but I keep getting 500 errors as:

"System.InvalidOperationException: Request format is invalid: text/xml.
   at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters()
   at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()
"

when I call it with javascript.

It is a simple web service that takes a single parameter as a string and returns it to the client. Please help!

Try putting in the full path to the Web Service rather than relative, other than that make sure the JS is on the same server. Note the Same-origin policy en.wikipedia.org/wiki/Same_origin_policy that will limit your JS calling to only directories at the same level or above. Are you able to call directly in the browser? — bcmoney

For those of you who this might help, the issue was setting the SOAPAction in teh header correctly:

$.ajax({ type: "post", url: target, contentType: "text/xml", data: soapBody, dataType: "xml", processData: false, beforeSend: function( xhr ){ xhr.setRequestHeader( "SOAPAction", "http://blahblah.com/Services/MethodName" ); }, ....

Make sure that your mess variable doesn't contain GET-style query string like '?a=1&b=2'. You need to send it in POST format, for example in JSON. Try to change contentType to contentType: "application/json; charset=utf-8"

$.ajax({
                url: service,
                type: "POST",
                dataType: "xml",
                data: '{key: value}',
                complete: endTest,
                error: processError,
                contentType: "application/json; charset=utf-8",
        });
