The bean code is not activate when-custom-point-event trigger

I wrote a java bean to read card reader Omnikey.  It works - almost.  When-custom-point-event is not fired.  Get the key of the reader in the java console, but then follows an exception.  The exeption complains, I believe, m_handler null variable in dispatchMessage() call which is what should be pulled when-custom-point-event in the form. I'm missing something minor and that everything works.  See Oracle Forms java console ATR key followed then path exception at the bottom of this post.  I have to FBean.Enable_Event.  What would be the name of the event listener?   I got the kifani of this example code: https://community.oracle.com/thread/68004------ this example isn't mention or implement a listener.  I just need to return the key and place it in a named text field: test.atr.

a time new form instance

FBean.Register_Bean('TEST.) CARD_READER_BEAN_AREA', 1, 'CardReader.CardReaderWrapper');

FBean.set_logging_mode('TEST.) CARD_READER_BEAN_AREA', 1, FBEAN. LOG_ALL);

button with when button pressed

fbean. Invoke('TEST.) CARD_READER_BEAN_AREA', 1, 'main');

When-custom-point-event

DECLARE
eventName varchar2 (30): =: system.custom_item_event;
eventValues ParamList;
number of eventValueType;
tempString varchar2 (100);
BEGIN
IF (eventName = "CARDINFO_EVENT") THEN
eventValues: = get_parameter_list(:system.custom_item_event_parameters);
get_parameter_attr (eventValues, 'CARDINFO_DATA', eventValueType tempString);
END IF;

- Then do something with tempString...
-for example
-message ("payload has been: ' |") tempString);
: test. ATR: = tempString;
END;

Java Bean code...

package, card reader;

import java.util.List;

Javax.smartcardio import. *;

Import oracle.forms.ui.VBean;
Import oracle.forms.properties.ID;
Import oracle.forms.handler.IHandler;
Import oracle.forms.ui.CustomEvent;

SerializableAttribute public class CardReaderWrapper extends kifani {
Property registered under the name of the custom event
Call it what you want...
public static String strOut = null; used in part of the code ATR

public static final ID CARDINFO_EVENT = ID.registerProperty ("CARDINFO_EVENT");

Property to set the name of the parameter that contains the payload
the event - for example your data
public static final ID CARDINFO_DATA = ID.registerProperty ("CARDINFO_DATA");

A reference to the Forms Manager associated with this component.
It is used to send custom form events
private IHandler m_handler = null;

*/
{} public void init (Manager IHandler)
Manager = m_handler;
Super.init (Handler);
}

/**

* Return to forms
* In this case, we use the pre-defined event and the IDs payload
*
@param payload < b > < /b > to return to the event data.
*/
Private Sub dispatchMessage (String payload) {}
try {}
The CustomEvent = new CustomEvent (m_handler, CARDINFO_EVENT);
m_handler. SetProperty (CARDINFO_DATA, payload);
super.dispatchCustomEvent (this);
} catch (Exception e) {}
e.printStackTrace ();
}
}


the rest of your bean code follows
and calls the dispatchMethod() method, which precedes
to contact forms

Public Shared Sub main (String [] args) {}

CRW CardReaderWrapper = new CardReaderWrapper();
Plant of TerminalFactory = TerminalFactory.getDefault ();

CardTerminals cardTerminals = factory.terminals ();

for (CardTerminal cardTerminal: cardTerminalList) {}

If (cardTerminal.isCardPresent ()) {}
Card card;

try {}

map = cardTerminal.connect ("T = 0");

card.beginExclusive ();
} catch (CardException e) {}
strOut = ("8"); This card but with card error
System.out.println (strOut);
crw.dispatchMessage (strOut);
continue;
}
ATR atr = card.getATR ();

Byte [] atrBytes = atr.getBytes ();
System.out.println ("0" + javax.xml.bind.DatatypeConverter.printHexBinary (atrBytes));
strOut = '0' + javax.xml.bind.DatatypeConverter.printHexBinary (atrBytes);
card.endExclusive ();
Card.Disconnect (true);

crw.dispatchMessage (strOut);
}

}

} catch (CardException e) {}
System.out.println("7"); no card reader not connected? ») ;
crw.dispatchMessage("7");

}
If (strOut == null) {}
System.out.println("9");
crw.dispatchMessage("9");
}
}

  • AiOSoftwareNPI (* .ms) the Setup program does not start when I start my computer.

    original title: AiOSoftwareNPI

    I'm having a problem with a software AiOSoftwareNPI problem (* .ms) the Setup program does not start when I start my computer.

    I know it's a Windows Installer but I don't have a disc with this route. I even tried to reinstall the windows xp disk and it does not work, I still

    get the same box when I shutdown and restart. The box allows me not to leave him continues to appear.

    Thank you

    Ms. C

    After doing a Google search for AiOSoftwareNPI and followed by the reading of many different threads in various forums, I found that it is for drivers for an HP all-in-One printer.

    You have an HP printer?

    If so, the usual suggestion was to place your HP printer disk in your CD/DVD drive and restart. After reboot would be installed the necessary files and the pop - up would more appear at startup. I don't know if it will actually work because in all the discussions I've read, none of the original poster never responded by saying that it worked or not.

    The next most common suggest was to download the latest driver for your HP printer to your version of Windows (including at the level of the ILO) and install it. Yet, not a single original poster has responded.

    In fact, if you have an HP printer I suggest to visit the web site of HP support below the link to get the latest drivers and their installation. Visit the support for the correct installation method and if you need to remove the old driver first. You can also visit the communities of Support HP for assistance (a link for communities is also on the next page).

  • We get the popup "USB device not recognized", when nothing is connected.

    Original title: pop up message

    I connected the USB cord to transfer information from your old phone to new phone via Itunes.  Since that time that I keep getting a pop up message that says: device not recognized USB, the defective device, windows does not recognize.  Nothing is plugged in, but message appears every few seconds.  How can I get him to stop?

    Hello

    It seems that you are getting the popup "USB device not recognized", when nothing is connected.

    What is the brand and model of your computer?

    I suggest to uninstall the USB controllers and check if you get the context menu.


    Method 1: Remove and reinstall all USB controllers


    a. clickStart, type devmgmt.msc in the start search box and press ENTER.

    b. expandBus USB controllers.

    c. right-click on each device under theBus USB controllers node and then click Uninstall to remove them one at a time.

    d. restart the computer, and windows will install the rear USB drivers.

    If reinstalling USB host controllers fails to resolve the issue, go to method 2.

    Method 2: See the procedure suggested by johnkelly46 responded on October 26, 2009, from this link.

  • In the face of "the device associated with this extension or the dial number is not valid" when you use DX80 telepresense phones

    Hi team,

    We have EX and DX series telepresence as endpoints agent. But DX series phones are facing issue "the device associated with this extension or the dial number is not valid" when checking in the agent. EX works very well. Both phones are properly recorded in CUCM.

    Can you please help me out here to solve the problem.

    Thanks in advance,

    Sisi.

    In my case, we tried to do a few different modifications here and there on the DX650 but never managed to do work.  Randomly, I was able to connect to the fineness with the DX650 as my camera, then my colleague could not connect to the Finesse with his 9971 as his camera - (keep in mind this was in an environment of model and it was just her and me as agents).  Since I saw this strange behavior and doesn't do not sense, we rebooted the server CCX. Once she is back to the top, we were also well able to connect successfully and had not had the problem since.

    Thank you
