How to integrate OMR into Apex app?

Hi guys,
My app would be ideal for OMR data entry.  OMR is Optical Mark Recognition.  Remember marking answers on tests by coloring in bubbles?  That's what I'm talking about.  ScanTron is the market leader in the field.  Anyway, can anyone share advice about how to integrate OMR into an Apex app?
Thanks,
Kim

Hi,
You can find lot of discussion from this forum how integrate devices like scanner or bar code reader with APEX.
And you might find that HTML and JavaScripts are not best chose to communicate with local devices.

    see the link that Jari provided.
    Also note that I'm "soon" going to release an updated version of the jQGrid Integration Kit, which contains a number of bug fixes and enhancements, so stay tuned to my blog or to the project page on Google Code ( http://code.google.com/p/jqgrid-for-plsql/ ).

    Back to your question: just put it in your jsp/xhtml page. Read its documentation what parameters it sends along the request and then catch them all in the JSF backing bean. You can either use ExternalContext#getRequestParameterMap() in the backing bean or use managed-property entries in the faces-config.xml to preset the properties of the (request scoped) managed bean after its creation using #{param}.

  • How to integrate JMS into WebLogic ?

    I want to use JMS for Messaging but I don't know how to integrate it into my WebLogic Server.
    Can anyone please tell me how I should integrate JMS into WebLogic?

    Java Message Service (JMS) is a standard API for accessing enterprise messaging systems.
    And WebLogic JMS is an enterprise-class messaging system that is tightly integrated into the WebLogic Server platform. It fully supports the JMS Specification.
    Please refer to the following links to get more information on this and how to configure the jms resources:

  • How to Integrate Oracle XE [ APEX ] & Adobe Flex

    How to Integrate Oracle XE [ APEX ] & Adobe Flex
    Just recently, I upload a quick screencast where shows how to integrate Ruby on Rails applications and Adobe Flex using http services <br>
    <param name=”movie” value=”http://www.youtube.com/v/IdM_rgDaVM0&rel=1”></param><param name=”wmode” value=”transparent”></param>
    This should be possible with Oracle APEX. I wonder if somebody have some ideas of a quick and easy export to generate the XML accessors for the Oracle XE instead of a htp.p PL/SQL Procedure ???
    The frontend with Flex will be the same, I just like to be able to automatically generate the XML version of the results, perhaps will be necesary some PL/SQL... applied to the end result of the query.
    Best Regards Dino.

    If it's raw XML output from APEX, how about a RSS feed as an example?

  • How do I get into the App Store for my mac mini ?

    How do I get into the App Store for my mac mini ?
    To get Apps FOR my mac mini NOT iPhone or iPad.

    BT ...
    Your profile shows you are running LIon v10.7 so you should be able to launch the App Store from your Apple menu > App Store, or from your Dock, or your Applications folder.
    If you can't locate the App Store, installing the OS X Lion Update 10.7.3 (Client Combo) will reinstall the App Store for you.
    Restart your Mac after the combo is installed.

    Hi,
    FileNet supports WebDav, so you can integrate FileNet as WebDav repository.

  • How to integrate these into footage?

    Hi
    Anyone know how to do this 3D stuff integrating it with live action footage? Can we do this in MOTION 4? Not the 3D graphics, but rather the integration of 3D graphics with HD footage? And what software is used for these? 3D studio MAX or Cinema 4D or what?
    How to integrate 3D GFX into footage? See this for examples...
    http://web.me.com/kbcv/VideoWork/test.html
    Thanks
    K

    You can do the second one (mario bros) with motion tracking in motion. The first one will require c4d or some 3D modeling software. Motion can composite the 3D sequence with the 2D video, but you'll need additional 3D tracking software... something like boujou, to get the tracking points on things like the book surface to integrate with 3D models.

  • How to integrate with a commerce app

    Is there a sample workflow for a shopper paying for access on a commerce website to view encrypted content?
    It seems that the player app will need to prompt for user authorisation, but what should the values be considering they bought the content on the commerce website?
    In the case of a subscription, what API should be called to update the CustomerAuthorization table?
    Many thanks in advance.

    Hi Kevin,
    If you would like to use complex business workflows, like the subscription workflow you've mentioned below, it's recommended you install the Reference Implementation license server, and not the license server for Protected Streaming.  Instructions on how to do this (which I assume you've already done) can be found on page 64 of the "Protecting Content" document: http://help.adobe.com/en_US/flashaccess/2.0/protecting_content.pdf
    After setting up your license server, packaging content, and confirming that you can playback encrypted content, you should take a look at page 70 of the document, where it goes into detail on "Implementing the usage models".  This is where you turn on the Reference Implementation's business model workflows.
    Regarding your question on what API you should use to update the CustomerAuthorization table - there is no API; this table is contained in your MySQL database.  You'll have to use SQL to update that table, or at least modify the "PopulateSampleDB.sql" file with whatever changes you want to that table, and re-run it.  In the real world, your web site portal will have to implement account management logic, which will handle things such as accept payment, and then update the appropriate tables needed to grant the proper access privileges to the user (like updating that CustomerAuthorization table).
    cheers,
    /Eric.

  • How to implement AJAX into APEX

    Hi Oleg,
    Thank you so much.
    KEY_LOC is the name(bind var) of the field not P1_KEY_LOC in page . I changed following:
    HTML Element attribute
    Onchange=onchange="f_getDet('KEY_LOC');"
    In javascript:
    ajaxRequest.addParam('x01',$v(KEY_LOC));
    And replace :P1_KEY_LOC to apex_application.g_x01 into application process.
    I have page0 but not sure it is public or not. How I could know?.
    Other users can access my application so I assume it is public but this my guess and do not know to check.
    I am still not able to get alert msg. I checked pop up blocker and it is disables.
    <script language="JavaScript" type="text/javascript">
    function f_getDet(KEY_LOC)
    --var keylocObj = document.getElementById(key_loc_select)

    --ajaxRequest.add('KEY_LOC',$v(KEY_LOC))
    ajaxRequest.addParam('x01',$v(KEY_LOC));
    ajaxResult = ajaxRequest.get('XML');
    alert('got it here!');
