Hi Mrf,
Your request is out of order, try this:
/***************************************/
function getUpdates()
{
var xmlHttp = new XMLHttpRequest();
xmlHttp.open("GET","http://localhost:8080/getUpdates.do",true);
xmlHttp.onreadystatechange = function()
{
if(xmlHttp.readyState == 4)
{
if(xmlHttp.readyStatus == 200)
{
view.alert(xmlHttp.responseText);
}
}
}
xmlHttp.send(null);
}
/***************************************/
Best Regards,
Wagner Nitsch Bressan
