XMLHttpRequest could not select proper transport descriptor

hello guys,

 

am creation an application for blackberry using phonegap.

In my code i use this code to get data from server:

 

 var url = "http://......." // here goes my url

var xhr = new XMLHttpRequest(url);
xhr.open("POST", url, true);
xhr.setRequestHeader("Authorization","********************************");
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.onreadystatechange = function() {

if (xhr.readyState == xhr.DONE) {
alert(xhr.status);

alert(xhr.response);
if (xhr.status == 200) {

alert("conn sucess");

}

else {

alert("conn err");
}
}

}
xhr.send("UID=" + nid);

 

my problem is that the code works fine on bb phones with OS version 6 or above, while with the lower versions the xhr.status = 500 and xhr.responseText returns  "could not select proper transport descriptor error"

does anyone know how to solve this problem?? 

 

regards,

ykuoles
