You can use jQuery and enable JSONP on your Ajax requests -- this assumes that the web service is JSONP-enabled. If not, you'll need a server-side proxy.

var url = 'http://localhost:8080/WebApplication3/resources/generic/hello?name=Kien';

    function callService(){
       var message= name='Kien';
        $.ajax({
            type: 'POST',
            url: url,
            data: {'name':'kien', 'age':58},
			//contentType:"application/jsonp;charset=utf-8",
			dataType:'jsonp',
			jsonp : "callback",
			jsonpCallback: 'jsonpcallback',
            cache: false,
            success: function(){
                alert('success');
            },
            error: function(data){
                alert('error');
            }
        });
		
    }
