Hi,
i want to use easyXDM for my GWT project and got the following
problem:
EasyXDM defines a global var called easyXDM. A regular request would
look like this:
var xhr = new easyXDM.Rpc(...)
xhr.request(...);
My GWT JSNI code is the following:
protected static native void testRequest()
/*-{
try {
alert('easyXDM: ' + JSON.stringify($wnd.easyXDM));
var xhr = new $wnd.easyXDM.Rpc({
'remote': 'http://127.0.0.1:12345/cors/
index.html'
}, {
'remote': {
'request': {}
}
});
xhr.request({
'url': 'http://127.0.0.1:12345/
MyCORSDocument.txt',
'method': 'GET'
}, function(response) {
$wnd.alert('success');
}, function(response) {
$wnd.alert('failure');
});
} catch(e) {
$wnd.alert('exception');
}
}-*/;
The problem is, that GWT knows easyXDM
(alert(JSON.stringify($wnd.easyXDM)); prints some code), but treats
easyXDM.Rpc as undefined (alert(JSON.stringify($wnd.easyXDM)); prints
'undefined').
The request results in an exception:
[INFO] [ERROR] Alert: easyXDM: {"version":"2.4.15.118","query":
