[flexcoders] JPG delivery via Java-App
Hi there, I searched a lot of time for a solution of my problem in other forums, documentations an so on. But I didn't find any hint so far, thus you are my last hope. The problem is as follows: I have a Java-Servlet or a Java-Class, which retrieves an image (JPG) from a database. As customary this Blob is stored in a byte array (byte []). The Flex-Application connects to the Java application to request the image. My problem is now to find a suitable datatype, which can store binary data in ActionScript. This means, I need a corresponding data type in ActionScript, which fits to byte[] in Java. Or does possibly anyone know a completely different solution for my problem?

RE: [flexcoders] JPG delivery via Java-App
Hi, Macromedia Flash Player doesn't have byte[] or its equivalent data type to store the binary data within AS. But you can load JPEG/SWF files using Loader/Image Flex classes or loadMovie(..) Flash Player API. If I am right, you want to load a JPG image in Flex app right? You can do that using Loader or Image tag mx:Image source=http://server.com/myservlet?imagename=logo; / Image/Loader can load non-progressive JPG and SWF files. -abdul -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of mummertm Sent: Tuesday, June 21, 2005 2:12 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] JPG delivery via Java-App Hi there, I searched a lot of time for a solution of my problem in other forums, documentations an so on.

RE: [flexcoders] JPG delivery via Java-App
To avoid having to save the image from the database to a physical file as an intermediate step you could try streaming the data from the database directly into the http request of the mx:image tag as Abdul suggests So, 1. Create a java/actionscript VO mapping that includes the image name as a sting. 2. After Flex has received the VO, trigger an event that request the image from the database either via an intermediate physical file save or directly streamed into the http request. Two requests for data instead of one, but it would get you the image. Hope this helps.
