Java - AIR Nativeprocess Performance?
Oct 30, 2010Is AIR nativeprocess able to receive message from Java program and process every line of message as fast as possible in milliseconds? Does it has a miss read or delay?

View 2 Repliesi am working on a flex+java combined project.My IDE and computer configuration is as follows:
[Code]...
When i make a small change in Flex code (eg, reposition of a button...anything), and run the project on server, it does make any change on output. Actually it depends on my luck... because it makes change in output randomly.what is is happening? tried rebuild, republish, clean , restart server, restarting the IDE, restarting the computer all available feature i could think. Also, i created a simple flex project on IDE and compiled it..... everything is compiled and displayed on output.
We have Flex/Java app with a typical scenario:
Clicking the button
Preparing request
Sending request to the backend
Receiving a response from the backend
Rendering the response
How can I measure time from the start of step 1 to end of step 5?
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.
this is what i'm trying to accomplish; With a click on a movieclip (cannon_mc)a shot is being fired (ball_mc)
The longer mouse is down, the speed of wich the ball is fired with should increase.My question to you is;
What is the most efficient way to accomplish this? With a timer or something like this;

I'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.
I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.
I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?
Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
eg.
<viewstack>
<tabnavigator />
<tabnavigator />
<tabnavigator />
</viewstack>
We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?

Then the problem come when I export the aplicaction AIR in .air and install the applicaction in the developer pc or other pc.

I have a program in AIR 2.6 for Windows and Mac Os platform. Use NativeProcess class to execute native apps that i have included in the project.

I would like to launch an external program on the server from a server-side ActionScript. My server-side scripting is in ActionScript 1.0 so I can't use the NativeProcess class, right? Can I use ActionScript 3.0 on the server? Is there another way?
View 3 RepliesI want to interact with a .jar-file in my AIR-project.I am using the NativeProcess feature in AIR2 for this, but it seems like I can't just define 'myJavaFile.jar' as the executable.On Windows, you can give 'java.exe' as the executable, the problem is Mac can't handle .exe-files.So my question is: how can I use .jar-files with the NativeProcess feature in AIR2. Or maybe there is an other solution to communicate with a .jar-files in AIR / AS3?
View 1 RepliesI want to pass two parameter to nativeProcess. While i am running exe file using windows command with parameter, it is working. Command for window is "abc.exe a.txt b.txt"How can I pass two parameters to the exe in that format using flex nativeProcess?This is what I have so far:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"

I gave up on Python and wrote the stdout interface with a C++ Win32 Console .exe file. It works fine. Bleegghh.
Old post: I'm trying to communicate with a Python script. It is not going well. So, first off, I can't get the damned thing to launch for the life of me -- so I'm focusing on that issue. I can get CERTAIN .exe files to launch, but not all of them. If I bundle putty.exe (lol) in a folder called NativeProcess it works fine, but I can't launch python.exe from my computer.

The NativeProcess is having a big issue which would hang/sudden stop response after 1-2 mins of running. I wonder if anyone else encounter the same issue?I have tested on Windows 7 (64bit).If there any way to launch an exe and release the Nativeprocess handler from monitoring the process or other method will be appreciate.
View 1 RepliesHow can I find the return value of a executable which has been invoked by a AIR app using the NativeProcess API? I am using Flash Builder 4. The following c++ generated executable
festival --tts "HelloSpeak.txt"
works fine on the Windows cmd line , but on invoking by the NativeProcess API like in the example article doesn't produce the desired result. I invoke the command with the arguments on a button click handler, but there is no TTS generated output.
I'm trying to use Imagemagick convert.exe with Flex4 NativeProcess. I know I have it configured properly because I can get a successful result with a simple call with no options to convert.

I am a .NET Developer, but the question I am having is not related to .NETPlease keep this in mind even if my question sounds very trivial.This is my question:We have an swf in the browser, which communicates with a java extensionIts done using Smartfox Server(Used for MMO apllications)From the swf we are grabbing a portion of the screen as "Byte Array" in action script(3).And in Java, we are calling a function that converts the ByteArray to Image and then saves it.ur Java developer is encountering the errorSo basically, what I would like to know is this:How to accept the object type Byte Array from ActionScript in Java?Whats Java object type that is mapped to Byte Array in ActionScript?The conversion part is easy, I dare say. code in the ActionScript Section
public function savePhoto(uName:String, ba:ByteArray, descr:String):void{
var obj:Object = {};
obj.arr = ba;

I tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.

View 1 RepliesI have a client-server multigame suite for PC ("kind of" cross-platform using cygwin), which is developed in Java(game menus and database management), C++ (server side), and adobe Flash (game graphics & interaction).
I have never tried to develop for android, so i have no experience.I am thinking of migrating this suite to google TV. So i would like someone with android experience to give a clue on the following :
1) Is it going to be easy to migrate the Java application to an Android application?
2) What kind of Flash support does Android have? Can it load directly swf applications? Does it have to load swf's through browser?
3) Can i find any kind of performance indexes for google TV hardware?
I need to load somehow the html code of a webpage A into a javascript string of another webpage B, on a different host. I know this is impossible to do with javascript alone because of the same origin policy, and I know I could do it loading the page via php on my server and then send results back to the user's client but I wouldn't be able to handle so many requests, so I need it to be done directly by the user's browser. I can use nearly whatever browser scripting language/applet framework common enough to be installed on the majority of my users' computers, like flash and java.On example, what if I use flash or java to load the external html code and then call a javascript callback function providing the source? Could this work?
View 2 RepliesI am using Flex 3 and make a call through a RemoteObject to a Java 1.6 method and exposed with BlazeDS and Spring 2.5.5 Integration over a SecureAMFChannel. The ActionScript is as follows (this code is an example of the real thing which is on a separate dev network);

If one doesn't have the source code, the only to test is to send keystroke and mouse move so I found this product but it's not free and opensource price is not even known :([URL] Squish supports automating interactions and testing non-HTML/DOM elements, that is, native objects, which are embedded in a web page. This is done at a fairly abstract level, which means that mouse and text input can be recorded and replayed.
In addition it is possible to inspect embedded native objects with the Spy tool and to insert verifications for these native objects. All of a native object's public properties can be accessed in test scripts.
I'm building a Facebook multiplayer game where the client side is in FLEX and the server side is in Java and I wanted to know if there is a guide on how to build the server clients managing system. When I say server clients managing system, I mean a server which many clients will connect to and will be able to choose between tables to join and play or to create their own table, same way as in texas holdem poker.
View 1 RepliesRight away i just try to explain my problem: Using BlazeDS i got the following Javaclasses:
[Code]...
Then i got a Flex service class calling BlazeDS and executing the getCategories java method. Since Flash dosn't seem to understand typed arrays, the result from that method which i get back in flex is a simple array of untyped objects (the mapping dosn't seem to work here, even tought the class category exists in flex and has the same properties).
thats the first thing. but however, i'm converting the untyped objects manually into objects of the category.as class. the second thing is that categories have child-categories within the java object, which are also ArrayLists of the type category.java. the problem about that: my result event object only contains the first level of categories, looking into them the children are allways null. i dunno why they are empty, since they ARE part of the java object category.
and the third thing (the strangest by fast), you maybe noticed i named the properties of the category.java class strange, like idCat and nameTest instead of simply id and name. why that? because the property names of my flex result objects dont seem to change when i change the java objects properties names (result object properties are named "id" and "name" but the java class object properties are named "idCAT" and "nameTEST"). that it REALLY strange, since if i set the properties, like you see at nameTEST = "TESTNAME" it IS recogniced by flex, only the proertyNAMES dont seem to be recognized at all.
