Hi All,
I want to retrieve images from server and send them back to Servlet without using FileUpload. It's an urgent requirement please help me out.

Thanks in Advance.

This is not better solution. I encode image with base64 and send to servlet. In
servlet i decode image to byte array and save to server.

I would now better solution too.
We have to waiting for someone who know more ... :)

Flex:

private function uploadImage():void {
var params:Object = { fileName: _fileRef.name ,
fileData: getBase64String(imgComponent)};
myHttpService.send();
}


private function getBase64String(component:UIComponent):String {
var bitmapData:BitmapData = new BitmapData(component.width, component.height,
true, 0xffffff);
bitmapData.draw(component);

var encoder:IImageEncoder;
// jpg, *.jpeg, *.gif, *.png
if (_fileRef.type.toLowerCase() == 'jpg' || _fileRef.type.toLowerCase() ==
'jpeg') {
encoder = new JPEGEncoder(80);
} else {
encoder = new PNGEncoder();
}

var bytes:ByteArray = encoder.encode(bitmapData);

var b64encoder:Base64Encoder = new Base64Encoder();
b64encoder.encodeBytes(bytes);

var b64String:String = b64encoder.flush();

return b64String;
}


Java:

import sun.misc.BASE64Decoder;
import java.io.*;

...

String UPLOAD_DOMAIN = "/MyUploadPath/";
String fileName = request.getParameter("fileName");

try {
if (fileName != null) {
BASE64Decoder base64 = new BASE64Decoder();

// Decode base64 to byte array
byte[] decodedData =
base64.decodeBuffer(request.getParameter("fileData ").toString());

// Save on server
FileOutputStream fos = new FileOutputStream(UPLOAD_DOMAIN+fileName);
fos.write(decodedData);
fos.close();

} else {
System.out.println("ImageCutUpload (failed): file name is empty.");
}
} catch( IOException e ){
System.out.println("ImageCutUpload (failed): write error: "+e);
}
