Hello guys,
I'm developing an application that GWT call Flex using
ExternalInterface.
To Upload image file to GWT server side(hosted mode) from Flex
application, I call Flex function FileReference.upload().
But it doesn't work.
Despite the fact that GWT server send "Http status 200" in GWT hosted
mode log, but ioerror or no event occur in Flex side.
(The image file is uploaded fine.)
I created a Simple Example that same trouble occur. Below is related
files:
Flex mxml code:
http://www.adobe.com/2006/mxml";
layout="absolute" xmlns:local="*">
Flex AS code:
package
{
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.net.FileReference;
import flash.net.URLRequest;
import flash.net.URLRequestMethod;
import mx.controls.Alert;
import mx.core.IMXMLObject;
public class FileUploadController
{
private static var _fileReference:FileReference = new
FileReference
();
public function startUpload():void
{
_fileReference.addEventListener(Event.SELECT,
selectHandler);
_fileReference.addEventListener(Event.COMPLETE,
completeHandler);
_fileReference.addEventListener(IOErrorEvent.IO_ERROR,
ioErrorHandler);
_fileReference.browse();
}
public function selectHandler(event:Event):void
{
var urlRequest:URLRequest = new URLRequest();
urlRequest.url =
"http://localhost:8080/SimpleGwt/myservlet";;
urlRequest.method = URLRequestMethod.POST;
_fileReference.upload(urlRequest);
}
public function completeHandler(event:Event):void
{
Alert.show("progressHandler: " + event);
}
public function ioErrorHandler(event:Event):void
{
Alert.show("ioErrorHandler: " + event);
}
}
}
GWT servlet code:
package simplegwt.server;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class MyServlet extends HttpServlet {
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse
resp)
throws ServletException, IOException {
// image save code here
PrintWriter writer = resp.getWriter();
writer.write("success");
writer.close();
}
}
web.xml code:
http://java.sun.com/dtd/web-app_2_3.dtd";>
MyServlet
simplegwt.server.MyServlet
MyServlet
/SimpleGwt/myservlet
SimpleGwt.html
Any help will be appreciated
Thank you
