I'm trying to create a simple Flash chat application for educational purposes, but I'm stuck trying to send a policy file from my Java server to the Flash app (after several hours of googling with little luck). The policy file request reaches the server that sends a harcoded policy xml back to the app, but the Flash app doesn't seem to react to it at all until it gives me a security sandbox error.

how to make a policy file for a socket server made on java with a client made on as2.
View 21 RepliesI read through the method to connect to a socket server : [URL]. I wrote an AIR application to connect to the java server code, but the client cannot connect. What is missing in the code?

We have a typical Flash+J2EE application that makes multiple requests from client to server (over Flex remoting), which is taking quite a long time on some client systems (and hence results in poor application performance on such systems).
Now, suspecting issues with network connectivity (latency) on such client system(s), we need to identify how far does it contribute to the slow response of the application (rather than performance issues in the application itself).
So, what are the best way(s) to diagnose this on a client system (Windows)?
Note that we have tried profiling our application, which does not indicate bottlenecks there, so we just need to clearly identify the possible network issues.
I'm trying to evaluate whether Flex can access binary sockets. Seems that there's a class calles Socket (flex.net package). The requirement is that Flex will connect to a server serving binary data. It will then subscribe to data and receive the feed which it will interpret and display as a chart. I've never worked with Flex, my experience lies with Java, so everything is new to me. So I'm trying to quickly set something simple up. The Java server expects the following:
DataInputStream in = .....
byte cmd = in.readByte();
int size = in.readByte();
byte[] buf = new byte[size];
in.readFully(buf);
[Code] .....
After that - EOFException happens on the server and that's it. So the question is, am I approaching whole streaming data issue wrong when it comes to Flex? Am I sending the policy file wrong? Unfortunately, I can't seem to find a good solid example of how to do it. It seems to me that Flex can do binary Client-Server application, but I personally lack some basic knowledge when doing it. I'm using Flex 3.5 in IntelliJ IDEA IDE.

Until now the procedure was simple, I've created a HttpStreamWriter and submitted my details to the login.php page, then get the cookies and later, when I want to get data from the site, I resubmit the cookie from the login.php page, but now there is a problem: an anti bot system: I'm not sure, but I think this is the system: [URL] The anti bot system creates a cookie, called anti-bot and I can't access the page without that cookie, the problem is that the cookie is generated by a flash application only after the page loads so I can't get the cookie from the page?

View 12 Repliese an application which is talking with Flash clients through sockets. The messages are in XML and not too long, up to 1000 chars. After the update the messages aren't received correctly at the client side - one byte is missing at the end. The first message is correct, the byte is missing from the end of the second message and the Flash stops because of the parse error.

Despite my luddite tendencies, I now have a phone with Java support - but no Flash support. I also have a copy of Macromedia Flash MX2004, though I'm unlikely to upgrade any time soon. What I'd like to be able to do is develop some content (including vector animations) in Flash, then use those resources in a Java Micro Edition application. I don't need all features of Flash - in particular, I don't care about ActionScript support. But I do want to be able to load a SWF file (or, perhaps better, an alternative file format that can be generated using a converter tool), and to be able to display animations and use other resources (particularly play sounds) from in that file.
Is there a good library and toolkit to support this kind of thing? Obviously (from the MX2004) it doesn't need to be completely up to date. On knowledge level - I've been a programmer for decades, and my everyday language these days is C++. However, I have a very limited knowledge of Java, and virtually no knowledge (yet) of Micro Edition and its libraries. I've already heard of Flash to J2ME converters, but so far as I can see they generate complete applications in one step, rather than treating the SWF file as a source of resources to be controlled from separately written Java code.
EDIT I get the feeling that this is (with slight modifications) probably quite easy. Java Mobile Edition supports SVG vector graphics. SVG supports animations. There are (I'm pretty certain) ways to convert flash animations to SVG - probably a simple export-to-SVG in the application, though I've not checked. This in itself doesn't give me a convenient bundle-of-media resources file format, but that's a relatively simple problem to solve, so long as there's a way to "load" SVG and other media files from some kind of non-file stream class that gets its data in turn from the bundle-of-media file.
I am attempting to setup a binary socket connection between flash running on my desktop and a Rabbit RCM3800 Microcontroller providing the server on my home network, which has no file system and has a very basic http server on it. Due to limitations of the microC I cannot run Java/Perl/Python or any other server on it other than setting up a server using its own native Dynamic C language (essentially manually opening and controlling sockets in C). I am able to successfully connect to a socket on port 3333 of the server and transfer information between the server and the .swf file when it is the sandbox type "local-trusted" (while I'm debugging in Flash).
Because of this I'm fairly certain the code to setup the socket between the server and flash works fine. My problem occurs when I try to run the .swf file as "local-with-network" (such as running it after publishing on my desktop) or "remote" (accessing the .swf file when it is located on the server) and it then requires a socket policy server to host a socket policy file on the server. On my server I have code setup such that whenever a socket opens on port 843 or port 3333 (my data port) and sends a stream of raw data containing the request <policy-file-request/>, the server writes back in ASCII the below code and closes the socket.
Code:
Select all<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "[URL]">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" />
</cross-domain-policy>
[Code] .....
So for some reason flash times out while waiting for the socket policy file. I have tested sending the <policy-request-file/> over telnet, and have received the above policy file. I have also sniffed using wireshark and saw that my desktop sent the policy request and received the policy file. I am guessing that Flash times out because it is waiting for some kind of terminating character that states the end of the policy file, and to that end I have tried sending. Interestingly, instead of sending the policy file I have tried sending random data from the server to flash, and flash displayed the Warning: Ignoring policy file at (URL) due to incorrect syntax. Because I don't receive this warning when I send my policy file I don't think it is formatted incorrectly.
I have also tried using the below flash code to hold the socket request open indefinitely, but it also errors after 20seconds.
Code: Select allSecurity.loadPolicyFile("xmlsocket://192.168.1.59:843");
The .swf file will eventually reside on the server itself at 192.168.1.59/myProg.html. I have only tested the flash file remotely on the server a couple times, and in addition to the previous warnings/errors, I received the warning: SWF from (URL) may not connect to a socket in its own domain without a policy file.

How can I create a flash video using Java.. (Java and JavaScript have nothing to do with each other, in my world Java Script is a useless technology).

Does the Adobe Media Encoder have a Java API that I can use.. if so, JavaDocs and an example?
Picture having two million directories, each directory has 30 photos and a sound clip. From this I want to produce two million flash movies each movie has 30 photos and the sound clip. Each movie has panning of the photos (Ken Burns, Civil War on PBS). What does Adobe have that I can call from within my Java code or Perl perhaps. I need to do this every two weeks, at least. Using a standard user interface is not going to work, even if I hired half of the planet.. I have been on the phone with Adobe for two days and have gotten nowhere.. surly Adobe has something which allows me to automate the creation of Flash movies. right?
I'm testing a full-screen Flash application. My preference is to drive the process with Java and I've had a lot of luck with the java.awt.Robot class. I'm looking for ways of modifying the test's behavior while the app still occupies the full screen. So far, I've found one "outside control", the caps lock key. If I see the process go horribly wrong, I turn on caps lock. Toolkit.getLockingKeyState notices that caps lock is on, and the test is terminated.
I need additional ways to change test operation, like "pause test" and "next test case." It looks like I could use num lock and scroll lock, but my tests need to run on Mac OS X, Windows, and Linux, so I can't count on having those keys. This is a small operation, so it's ok if the method isn't refined. But not as kludgy as overloading the caps lock key with 5 different operations. I have no internal control of the application; I'm supposed to "test" just like a user.

View 9 RepliesI'm building a Flash-based Facebook game with a Java backend, and I'm planning to use a RESTful approach to connect the two of them (not a persistent socket connection). I'm using the AS3 library to connect the client to Facebook, so that's where I have my session information stored. However, how do I authorize client connections back to the server? I can't leave the callback URLs open since that'd let people manipulate game state without playing the game. I need to make sure that the calls are coming from a valid client and through a valid session.
At the moment, users have no direct login to the backend server -- it's all handled through the client frontend. Can I pass the Facebook OAuth2 access token to the backend in a way that the backend can verify its validity? Should that be enough to trust a valid frontend connection?
I could do a two legged OAuth signed request or just use a simple shared secret, but the keys would have to be packed in with the flash client, which makes that almost useless for this use case.
