Re: GWT RPC with Adobe AIR 2
I found it easier to modify the cache.html file and replace
self.onreadystatechange = new Function with self.onreadystatechange =
function(){}
I tried to modify the RPC Url with the setServiceEntryPont() method
which changes the URL but the request method is no longer POST but
OPTIONS. I tried creating a custom RpcRequestBuilder and still uses
the OPTIONS method.

Re: GWT RPC with Adobe AIR 2
Well i think i ve figured it out
the first Problem is in the RequestBuilder class. (Well actually is the
XMLHttpRequest Class)
take a look at the XMLHttpRequest Class in the method *clearOnReadyStateChange
(*line 113)
public final native void clearOnReadyStateChange() /*-{
var self = this;
$wnd.setTimeout(function() {
// Using a function literal here leaks memory on ie6
// Using the same function object kills HtmlUnit
* self.onreadystatechange = new Function();*
}, 0);
}-*/;
this throws an error inside adobe AIR.
So to overcome this i did someting like this inside the RequestBuilder Class
in the doSend Method (around * line 381*)
// Must set the onreadystatechange handler before calling send().
xmlHttpRequest.setOnReadyStateChange(new ReadyStateChangeHandler() {
public void onReadyStateChange(XMLHttpRequest xhr) {
if (xhr.getReadyState() == XMLHttpRequest.DONE) {
/**
* Avoide new Function security error in Adobe AIR
*/
* if(! Runtime.isAIRRuntime()){*
*** *
*** **xhr.clearOnReadyStateChange();*
*}*
* *
* request.fireOnResponseReceived(callback);*
*}*
}
});
The Runtime class is a class i created my self.
After you have done this you are half way :)
You need to make a change in RemoteServiceServlet class too. Because the
modeBaseURL of the adobe air application istarts with
*app:/ . This will throw an Exeption so you need to change that *
*
*
*i did something like (RemoteServiceServlet around line 41*) * :*
*
*
*
*
*
if (moduleBaseURL != null) {
try {
if(moduleBaseURL.indexOf(app:) = 0){
moduleBaseURL = moduleBaseURL.replaceFirst(app:/,
http://127.0.0.1:/;);
}
modulePath = new URL(moduleBaseURL).getPath();
} catch (MalformedURLException ex) {
// log the information, we will default
servlet.log(Malformed moduleBaseURL: + moduleBaseURL, ex);
}
}
And after that GWT RPC is running with Adobe AIR.
Hope this could help

Yeah you are right.
It looks the gwt is generating some new Function(){...} constructs,
what adobe air doesnt like.
Anybody has a solution to this ?
I m also really interested

Because you have to write some of the conversion process manually
which is automated with GWT.
Unless you know of a project that is a drop-in replacement for RPC
with no extra code required?

Re: GWT RPC with Adobe AIR 2
We have a very large app that uses air extensively (both online and
offline modes). We had to jump through many hoops to get RPC working.
For AIR compiles, we replace the following class with this method:
public final class ClientSerializationStreamReader extends
AbstractSerializationStreamReader {
private static native JavaScriptObject eval(String encoded) /*-{
return $wnd.parseGwtRpc(encoded);
}-*/;
... etc
}
Air is unable to eval gwt returned responses over a certain length, as
they are turned into arrays on the server. So we decode them if they
are this type...
// in your js file which is included...
String.prototype.endsWith = function (s) { return this.length =
s.length this.substr(this.length - s.length) == s; }
function decodeGWT(s) {
if( ! s.endsWith(])) ) return s;
var end = s.indexOf(].concat();
var first = s.substring(0, end+1);
var second = s.substring(end+].concat(.length);
var arr = eval(first);
var middle = second.indexOf(],[);
var current = 0;
while( middle != -1 ) {
var x = second.substring(current, middle+1);
var arr2 = eval(x);
arr = arr.concat(arr2);
current = middle + 2;
middle = second.indexOf(],[, middle+1);
}
var y = second.substring(current, second.length-1);
var arr3 = eval(y);
return arr.concat(arr3);
}
function parseGwtRpc(encoded){
return eval(decodeGWT(encoded));
}
If you need any help feel free to email me.

GWT RPC with Adobe AIR 2
How do you call GWT RPC from Adobe AIR? Is it possible? I get a security violation from AIR. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT RPC with Adobe AIR 2
Hi, GWT RPC is just an HTTP POST. From this point of view it should be possible. However, GWT RPC is passing an id in the headers which is changing every compile. So you must simulate this, too.
