Calling WCF service from Javascript

Hi,

 

I have a very simple WCF based WebService - "HelloWorld()" which return "Hello World". Using javascript and xmlHttpRequest I can invoke this service from Browser. But the same page dosn't work when run from Blackberry.

 

Issue: xmlHttp.readyState alerts "1" twice, but don't proceed further.

 

Javascript:

 

 

function HelloWorld()
{
// Create HTTP request
var xmlHttp;
xmlHttp = new XMLHttpRequest();

// Create result handler
xmlHttp.onreadystatechange=function(){
alert(xmlHttp.readyState)
if(xmlHttp.readyState == 4){
alert(xmlHttp.responseText);
}
}

var url = "http://localhost:2398/HelloWorldService/Service.svc"
var body = '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body>' +
'<HelloWorld xmlns="urn:HelloWorld" />' +
'</s:Body></s:Envelope>';
alert(body)
// Send the HTTP request
xmlHttp.open("POST", url, true);
xmlHttp.setRequestHeader("Content-type", "text/xml; charset=utf-8");
xmlHttp.setRequestHeader("SOAPAction", "urn:HelloWorld/IHelloWorld/HelloWorld");
xmlHttp.send(body);
}

 I see an alert message "1" (in bold line above), then again "1" and then no message comes. Blackberry's small loading icon rotates few times and it too vanishes.

 

The same script works well from IE.

 

 

Any Suggestions?

Re: Calling WCF service from Javascript

Hi,

 

Thanks for the link but that didn't help me as I was doing the same. While trying options, I added all blackberry features to the web service domain I added earlier. After this, service started working fine. I am not sure, which specific blackberry api feature of long list made it work, but adding all resolved this problem.
