Invoking methods on a native process in Air 2.0

Hi all,
I wanted to know if it was possible to call methods (declared as public) on a native process with Air 2.0.
Any help would be appreciated,
Thanks in advance,
Julien

Hi Julien,
It isn't possible to call methods directly with the new native process api's.  Instead you'll communicate via stdin and stdout.  Please check out this document for further details: Interacting with a Native Process
Thanks,
Chris

  • Native Process Issue in AIR 2.0

    I have written an AIR application in "Windows" that invokes a third party application through "Native Process APIs" offered in Adobe AIR 2.0 Beta. The issue is when my application invokes the third party application, a command prompt window appears until it get finished executing. Its really irritating in terms of GUI and I would like to get rid of it. Please let me know if there is any solution?
    Waiting for all of your precious words...
    Thanks

    Yes, my application is taking command line aurguments. Here is the code:
                var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
                nativeProcessStartupInfo.arguments = aurguments; // Array of aurguments
                nativeProcessStartupInfo.executable = file;
                this.process = new NativeProcess();
                process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
                process.addEventListener(ProgressEvent.STANDARD_ERROR_DATA, onErrorData);
                process.addEventListener(NativeProcessExitEvent.EXIT, onProcessExit);
                process.start(nativeProcessStartupInfo);

  • Problem with AIR 2 Native Process?

    I had installed Adobe AIR 1 before and Flex Builder 3.0 (licensed) on a Windows Vista machine. Now i have installed AIR 2 framework (without uninstalling AIR 1, assuming that it will update that). I m trying to write a small code to use AIR 2 Native Process functionality but AIR is not recognizing Native Process classes/objects. Even i have tried a sample code from Adobe Developers Center article http://www.adobe.com/devnet/air/flex/quickstart/interacting_with_native_process.html but no way.
    Please let me know wat is wrong? How i can use AIR 2 new features? How to upgrade to AIR 2?
    Looking forward for an earliest response.
    Thanks
    Asad Ijaz

    Thanks romil!
    I have installed AIR 2 but without uninstalling AIR 1. Should i uninstall AIR 1 before i install AIR 2?
    Regard,

  • Very strange bug with AIR and native process (Windows 7, EXE)

    Hello to everyone!
    The situation is:
    I've made an AIR Application, inside of that is running a native process - EXE file.
    I'm using Flash CC as IDE and tried to use compile that as EXE with AIR 2.6 and 3.6 - results are same.
    So I've insert inside a checking if Native Process is supported or not and the Native process is supported all the time.
    When I've just installed the application and run it - the very first attempt is good - everything is working as a must: internal EXE is called by my Application with necessary parameters as many time as I'm need.
    However if I'll close the App and then will run it again - internal EXE is not starting at all, doesn't depends on number of attempts to re-start of the App.
    So only way is to uninstall, install it back and then you'll be one more session of successful internal EXE-requests, till the next re-start of the App.
    That's it.
    I've tried to "google it" but unsuccessful. Probably the bug is very rare.
    Help me please?
    Update: at compilation with Flash CC IDE it's working all the time with no any issues.
    Update-2: when I'm running installator-EXE, there is going a notification "Same version is installed, etc." and then selected "Run Now" - there is also working with no problems.

    Well, I've found the solution and answer by myself and here is it please:
    In case with same situation as above you need to add just one line in your AS3-code
    nativeProcessStartupInfo.workingDirectory = File.applicationDirectory;
    And you will be happy so much

    This is a very convinient feature of Weblogic startup service - if your class
    does not implement T3StartupDef it will look for (using introspection)
    public static void main(String[] args) in your startup class, and, if it is
    there it will execute it.
    Ricky Wong <[email protected]> wrote:
    It works, many thanks !
    However I still have one more question out of my head - I found that my
    startup class doesn't need to implement the T3StartupDef and it still
    works, however my shutdown class must implement the T3ShutdownDef
    (otherwise I'll get ClassCastException).
    In article <[email protected]>, [email protected] says...
    Most likely the HubDevicePool does not have a public default constructor.

    Message was edited by: aswathykrishnan

    Hello Aswathy, these days I'm also coding an application which uses AIR NativeProcess and I required to open the MacOS terminal with some parameter/commands. I also eventually turn to the AppleScript, but I considerably new to the AppleScript, yet trying to findout a way to passing parameters (the command argument) to the AppleScript; the appleScript I managed to open but not passing the argument. Can you please help? here's my some probable codes for the application:
    My appleScript is:
    #!/bin/bash
    on run argv
              tell application "Terminal"
                        set currentTab to (do script) & item 1 of argv
              end tell
    end run
    I've packaged the appleScript as an Application (Contract.app) and here's my Flex code:
    var npInfo : NativeProcessStartupInfo = new NativeProcessStartupInfo();
    npInfo.executable = new File( "/Applications/Contract.app/Contents/MacOS/applet" );
                                  var arg:Vector.<String> = new Vector.<String>;
                                      arg[0]="ssh [email protected]";
                                  npInfo.arguments = arg;
                                  process = new NativeProcess();
      process.start( npInfo );
    Can you please help?
    Thank you.

  • Native Process works OK in FlashBuilder 4.6 'run' but won't export build

    Hi,
    I have a small application that uses the 'native process' feature to invoke Image Magick to process an image file. My environment is Widows 7/64 bit.
    The application runs perfectly within FlashBuilder 4.6 using the 'run' facility and with 'supported profiles' set to 'extendedDesktop' in the -app.xml file.
    But when I try to export-build it, I get an error message (306) listing the supported profiles but extendedDesktop is not one of them.
    I have also tried to package this using the native Flex 4.6 SDK but the same error occurs.
    If I add 'desktop' to the supported profiles, the application will export build, and then allows the creation of the exe from the air file.
    But the exe will not run and just 'hangs' once you get to the point where the native proessing is invoked.
    The native process documentation says that extendedDesktop is required so the application using 'desktop' perhaps understandably 'hangs'.
    Any assistance with this will be most appreciated.

    OK, found the problem - I need to export-build the app as 'signed native installer' not 'signed AIR package'.
    Thanks to the answer to a similar problem in this forum from 2010.

    Hi there, have you integrated the AIR 2.0 SDK with your Flex 4 SDK? It is needed to run the AIR 2 samples. It's not yet included in the Flex 4 SDK.
    You can download the SDK here: http://labs.adobe.com/downloads/air2.html
    and the instructions for how to integrate it with your Flex 4 SDK are listed in the release notes (or here: http://labs.adobe.com/wiki/index.php/AIR_2:Release_Notes)
    Hope that helps!!

    I have seen this in 10.1.3.1.0, which was fixed in 10.1.3.3 pactset and above.
    Please apply 10.1.3.3 patchset and try again.

  • Creating native processes

    Hi,
    Runing SuSE Linux 8.0, java 1.4.0
    I'm trying to create a native shell (I/O dumped into a JTextArea) woith java, the problem is that once I have invoked bash, it somehow manages to work out that its not running in a real console and behaves as if my input was a script. I managed to get bash working properly with command line args, but now when I want to start other interpreters on top of it they too seem to detect they are not in a proper tty.
    Is there a way to make native processes behave as if they were run from, say, an xterm?

  • Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi

    Hey there,
    we have sensors on an Engine which are connected to a NI cRIO 9014 board (with a NI9411 6-channel digital input modul) and go from there via network to a host computer.
    cRIO board: the cRIO board collects the data from the engine and stores it in a buffer, this is because the network is to slow for the magnitude of data
    host computer: the host computer reads over the network the buffer on the cRIO board, on the host computer it takes out specific portions of the data to create pressure graphs of the engine
    Error: 
    Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi
    Possible reason(s):
    The transfer did not complete within the timeout period or within the specified number of retries.
    This error occurs in the following scenario:
    - engine is running
    - cRIO is running
    When I press the start button (boolean 3) in the host.VI to start the reading of the data from the board AFTER I pressed the run button of the host VI. 
    The Error would not occur if I pressed the start button (boolean 3) BEFORE I pressed the run button of the host VI.
    We tried to increase the time out, but it still did not work, the error occurs!
    We would be really happy if you could look over it and help us in this case! If you need further informations or if we need to clarify some specific portion, please let us know!
    We included the VI's in the attachement!
    Thanks in advance!
    Solved!

    Chrisse,
    There are a few things wrong in your application, if I may offer some suggestions.
    First, your while loops are not running in parallel.  In fact, they are in while loops with a true constant wired to them. I am not sure if this is by design for debugging, or on accident.  I would put the Polling(read pulling zero elements) outside your main while loop.
    Your second nested while loop (the one polling the # of elements and then pulling them out) is going to run just once, and may pull only a few samples.  I don't think that is what you are looking for here, and there are a couple ways we can go here.  You could continuously poll until you have 0 elements available for x amount of time, then you know you have no more samples available and you can process all the data OR you can put all of your data processing as part of that loop and just always write to file immediately as x samples are pulled.
    Also, your main loop's stop condition is (i <= 3) Therefore, it will run once and then stop.  Maybe you mean >=3?
    Also, you have 'append to file' disabled on your write to spreadsheet, so everytime you write you are overwriting old data.  If you want to continuously write, you will be losing data.  This can be cured by either setting this to true(requiring a new file name or programatically deleting the old spreadsheet every time you run the vi) OR you can collect all of your data in a shift register, and only write to file once you have all your data available.
    The error you are seeing is because you try to close your FPGA reference twice.  You only need to close it once.
    After seeing your overall picture, I think this can all be cured by simply hardwiring your Read to get your 1440X4 elements, but as we have seen, this does not work.  Something is happening in your system....this is what I want you to do...run just the following code...and let me know how many elements remaining it gives you...Once the number has settled(I hope it does and your engine doesn't keep running), hit stop, and all the values will be put on a graph for you.  My broken wires are because I do not have the FPGA VI.

  • Problem with blocked native processes

    My application relies heavily on native processes so that I am trying to implement fallback strategies if a native process doesn't work as expected.
    While creating test scenarios I had a problem with handling errors caused directly by the start() method of the NativeProcess class. It throws errors if the target process can’t be accessed or is corrupted. For example if you take an exe file in Windows that works correctly and modify it in a hex editor to corrupt it the following error is thrown:
    Error: Error #3219: The NativeProcess could not be started. '%1 is not a valid Win32 application.'
          at flash.desktop::NativeProcess/internalStart()
          at flash.desktop::NativeProcess/start()
    If I try to put a try-catch block around the process.start() call something unexpected happens:
    The error is cought correctly, but another error is thrown instantly:
    Error: Error #1503: A script failed to exit after 30 seconds and was terminated.
          at mx.managers.layoutClasses::PriorityQueue/removeSmallest()[E:\dev\4.x\frameworks\projects\ framework\src\mx\managers\layoutClasses\PriorityQueue.as:238]
          at mx.managers::LayoutManager/validateProperties()[E:\dev\4.x\frameworks\projects\framework\ src\mx\managers\LayoutManager.as:567]
          at mx.managers::LayoutManager/doPhasedInstantiation()[E:\dev\4.x\frameworks\projects\framewo rk\src\mx\managers\LayoutManager.as:730]
          at mx.managers::LayoutManager/doPhasedInstantiationCallback()[E:\dev\4.x\frameworks\projects \framework\src\mx\managers\LayoutManager.as:1072]
    The problem with this error is that I got no idea how to catch or prevent it. Depending on what I do in the catch block there is another error. For example if I try to log the error I get (but sometimes not as instantly as above):
    Error: Error #1503: A script failed to exit after 30 seconds and was terminated.
          at mx.logging::Log$/getLogger()[E:\dev\4.x\frameworks\projects\framework\src\mx\logging\Log. as:360]
    Strange is that the error is fired instantly sometimes not after 30 seconds.
    How can I fix this?

    In the first case I used a loader to load an error image. In the second case I tried something like:
    var logger:ILogger = Log.getLogger("Test");
    logger.error("NativeProcessError");
    I don't have the exact code at the moment, because I'm not on that computer.

    <Utils> <buildFacesMessage> ADF: Adding the following JSF error message: Cannot invoke method multiply() on null object
    any help please ?

    Thanks Frank ,
    really i've already downloaded the ZIP of the final application , but the same error message ,
    when removing the Annual salary ( Which is a new Attribute ( not DB column) Salary * 12 ) every think is fine and no more error message ,there is no null salary all the employees have a salary , my JDeveloper Version is 11.1.2.1.0
    also , because of the EmpDetails is based on the query
    FROM EMPLOYEES Employees, DEPARTMENTS Departments
    WHERE Employees.DEPARTMENT_ID = Departments.DEPARTMENT_ID
    and the Department id is non editable value , that means even if you add a new user u cant never check this user in this interface , u can check this user only on DB (SQL) level .

  • Conversion Error: I/O error while communicating with native process

    Hi,
    I am trying to use Oracle Outside In Technology Image Export for conversion of images. I am trying to run the example ExportTest that comes with the downloaded SDK.
    I get the below error while running the ExportTest example.
    Conversion Error: I/O error while communicating with native process .
    Am I missing any settings?
    Please guide to the right forum if this is not the one for posting queries on Oracle Outside In Technology Image Export.
    Thank you.

    Hi Revanth,
    I am using Image Export 8.3.7 and I am trying to run the java class "ExportTest" that is in the location sdk\samplecode\ExJava\Examples\ExportTest\src of the download.
    My input folder has one jpg - puzzle.jpg (this is just a simple jpg), I am trying to convert it to TIFF. ExportTest.java uses the classes in Export.jar . Export.jar is located in the sdk\samplecode\ExJava\Examples\ExportTest . You can see source files of the Export.jar at location sdk\samplecode\ExJava\Java API\src of the download. I am running the 'ExportTest' by providing the arguments (input folder, output folder and ix.cfg - this file comes with the download). So now when I run this class I was getting the error I mentioned in this post. Inorder to find more details about the error I modified the 'Export.java' (at sdk\samplecode\ExJava\Java API\src\com\outsideinsdk) just to printStackTrace when the exception occurs and rebuilt the 'Export.jar' and ran the 'ExportTest.java'.
    And below is the stack trace that I got :
