Java 8 & listening to greetings in UNITY 9.1

Cisco Unity Connection v9.1.2ES46.12900-46 Java 8 Update 25
Looks like adding the server dns or IP to the exception list does not do the trick to allow the "Play/Record" button to work when listening to greetings within Unity Connection. Tried every browser and java setting.. Any workaround for this?

And that doesn't work half the time either. This has to be one of the weakest parts of Unity. I have had multiple TAC cases open on this at different times and always end up uninstalling java and reinstalling 3 or 4 different versions then it magically works. Only for the next time you go to use the greeting or message play back to not work. I think last time I had to go back to Java 6 release 45 or something like that.

Error trying to register a Java event listener

I'm trying to register a java event listener in 11g with the following piece of code:
DECLARE
b BOOLEAN := FALSE;
BEGIN
b := DBMS_XDB.createFolder('/public/resconfig');
b := DBMS_XDB.createResource(
'/public/resconfig/hr_event.xml',
'<ResConfig xmlns="http://xmlns.oracle.com/xdb/XDBResConfig.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.oracle.com/xdb/XDBResConfig.xsd
http://xmlns.oracle.com/xdb/XDBResConfig.xsd">
<event-listeners default-language="Java">
<listener>
<description>Category application</description>
<schema>HR</schema>
<source>xdbproject.OpenOfficeEventHandler</source>
<language>Java</language>
<events>
<Post-Create/>
<Post-LinkIn/>
</events>
</listener>
</event-listeners>
<defaultChildConfig>
<configuration>
<path>/public/resconfig/hr_event.xml</path>
</configuration>
</defaultChildConfig>
</ResConfig>');
END;
This results in the following error message
ORA-31146: Ugyldig lytterkilde HR.xdbproject.OpenOfficeEventHandler
ORA-06512: ved "XDB.DBMS_XDB", line 174
ORA-06512: ved line 5
which translates to Invalid listener source.
My class is loaded in the HR schema, and implements the XDBRepositoryEventListener
Does anybody have a suggestion to what I'm doing wrong, or how I can find out what makes my class invalid as a listener source?

Check if it validates against the restrictions set in the XML Schema (Appendix A, Oracle XMLDB Developers Guide):

Force to java to listen events

My problem is this: when When i�m executing certain loop in my application, the JVM doesn�t listen the events that occurs (that is, the actionPerformed method isn�t invocated when i push a JButton). When the loop finished, the problem dissapear. �Anybody knows some call that force to java to listen events?. I�ve tried to implement this loop in a thread but the problem doesn�t dissapear.
Thanks.

if the loop is started from a gui event handler, take a look at SwingUtilities.invokeLater() method

Air Native Extension - Java Key Listener

Hello all,
Firstly I'd like to thank you for creating an excellent and helpful community. I have an issue I have been stuck on for around 2 weeks now.
I am creating an android native extension to listen to key input from a proprietary remote control device. GameInput does not recognise it as a game controller so we have to create a native extension to get the input. I have it working fully except for one issue; if the game loses context (eg the user gets a phone call or the game goes into the background for any other reason) I do not get any other input.
The way I am doing it is to attach an onKeyListener to the currently focused View (an AirWindowSurfaceView). This works perfectly, but when the context is lost I'm assuming the AirWindowSurfaceView changes and I cannot find a way to get a reference to the new one. Here is my key listener setup code (from the native Java):
public void updateListeners()
    if(_view != null)
      _view.setOnKeyListener(null); //remove from the old view
      _view.setOnGenericMotionListener(null);
    _context.dispatchStatusEventAsync(_view.toString(), "view"); //send the current view details
    _view = _context.getActivity().getCurrentFocus(); //set the new view
    _context.dispatchStatusEventAsync(_view.toString(), "view");
   if(_onKeyListener == null)
       _onKeyListener = new NativeGamepadKeyListener(_context, this); //create new key listener
   if(_onGenericMotionListener == null)
       _onGenericMotionListener = new NativeGamepadMotionListener(_context, this); //create a new motion listener
   _view.setOnKeyListener(_onKeyListener);          //set on the new view
   _view.setOnGenericMotionListener(_onGenericMotionListener);
This updateListeners function is called when I get a focus change event on the current view (attached in a similar way) but this doesn't seem to keep it up to date with the current View.
Please note I'm a newbie at making extensions like these and might be going about it totally the wrong way - if I am and you have any suggestions as to the best way to use an onKeyListener in a native extension I'd love to hear it.
Thanks in advance for your help!

I am not able to solve this yet. Is anybody else facing this this problem.

How do I resolve connection error with Java API listener?

This message is triggered whenever I generate a data event that I would otherwise expect to be captured and handled by the listener. I have tried a number of things, including setting the connection to NO_TIMEOUT and trying SimpleConnection versus ConnectionPool, but always with the same result.
Here is some sample code for the listener:
public class DataListenerImpl implements DataListener {
     public void recordAdded(RecordEvent evt) {
          System.out.println("===> Record Added Event");
          System.out.println(evt.getServerName());
     public void recordCheckedIn(RecordEvent evt) {
          System.out.println("===> Record Checked In Event");
          System.out.println(evt.getServerName());
     public void recordCheckedOut(RecordEvent evt) {
          System.out.println("===> Record Checked Out Event");
          System.out.println(evt.getServerName());
     public void recordModified(RecordEvent evt) {
          System.out.println("===> Record Modified Event");
          System.out.println(evt.getServerName());
And here is the code for the Event Dispatcher:
public void execute(Repository repository) {
     DataListener listener = new DataListenerImpl();
     try {
          EventDispatcherManager edm = EventDispatcherManager.getInstance();
          EventDispatcher ed = edm.getEventDispatcher(repository.getServer().getName());
          ed.addListener(listener);
          ed.registerDataNotifications(SystemProperties.getUserName(), SystemProperties.getPassword(),
                    repository.getIdentifier(), repository.getLoginRegion());
          ed.registerRepositoryNotifications(SystemProperties.getUserName(), SystemProperties.getPassword(),
                    repository.getIdentifier());
          ed.registerGlobalNotifications();
          while (true) {
               Thread.yield();
               try {
                    Thread.sleep(1500);
               } catch (InterruptedException ex) {
                    System.out.println("Interrupted Exception: " + ex.getMessage());
     } catch (ConnectionException e) {
          e.printStackTrace();
     } catch (CommandException e) {
          e.printStackTrace();
Has anyone else encountered this message? Could it be related to a TCP configuration on the server? Or is this a bug in the Java API?
As I mentioned in the forum posting linked to above, I have not encountered this problem with the MDM4J API.
Any help is greatly appreciated.

I resolved it. We are switching over to SP6, Patch 1 and the listener code works fine with this version of the Java API.
Just one thing to note, though: make sure that you register data notifications through MetadataManager in your initialization code:
metadataManager.registerDataNotifications(userSessionContext, repositoryPassword);
For information on the changes to the SP6 Java API, especially with regard to connecting to MDM with the UserSessionContext, please review Richard LeBlanc's [presentation|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20073a91-3e8b-2a10-52ae-e1b4a10add1c].

On which ports Java Connector listens ?

Hey,
How is listening for RFC connections handled in Java Connector (as in Business Connector) when server registers itself in R/3 as a Program ID ?
Is there a TCP/IP port listener (a listening TCP/IP socket) or maybe the JCo RFC library opens a TCP/IP connection to the R/3 and keeps it alive ? If a TCP/IP port is open, what number is it
Please help, this is urgent. I tried to find some information in the documentation - nothing. I also tried to setUp a listener using Business Connector and watch the open ports, but having two listeners for different servers i saw only one port open beside the HTTP port of Business Connector and this port number was not meainingful.
regards
Marcin

sorry i meant to say -
try doing a netstat to see which port it is listening to..

Can Java Socket listen from VB?

I have a program that first writes some data on output stream on socket , on which VB program is listening..and then it try to read from input stream what VB program would write back. Everytime I write the data , it doesnt throw any exception at that point and when I do inStream.read() , it returns -1 indicating end of stream. However, when I run a VB client using WinSock , it works perfect!!! I thought it should not matter whether client is java or VB ..but was wondering if any of you have any opinion on this? My java client just doesnt seem to work. Both are communicating through TCP protocol.
fyi: following is the piece of code..
    outStr = socket.getOutputStream(); // connected
    outStr.write(vgBufferOut); //vgBufferOut is bytes array.
    socket.shutdownOutput(); //if I dont shutdown output stream server will stay in the loop
    inStr = socket.getInputStream(); //get the input stream
     vlLenbufferIn = inStr.read(vlBufferIn); //store it in byte array vlBufferIn and get length.
      System.out.println("Length is " + vlLenbufferIn);   //This always returns -1

I believe it should work. Did you try it with a java server on the other side? If you are completely stuck try using a TCP monitor to monitor all data that is transmitted. I recommend the one provided with Apache Axis:
http://docs.pushtotest.com/axisdocs/user-guide.html#tcpmon
but I am sure you can find others too.

Java Http Listener to parse incoming XML

Hey folks,
I have a task where I need to create a secure http listener, which will then parse an incoming XML. Parsing an XML document seems pretty straight forward so no problems there.
basically what I would like to know is how would I get started? Would I use a servlet? Im not familiar enough with the capabilities of Java to know what packages to use and whatnot. How would some of you go about designing such a system?
Thanks in advance,
Ken

Yes, you can write a Servlet which does that.

How to use java to listen to a socket?

i want to create a listener to monitor the input and output of a very socket,i don't know which classes can be used.
thk u very much!!!!!!

You can't create a socket in java to 'monitor the output'. At least not in the general sense.
In the general sense this is usually referred to as raw sockets and the default java does not do that. You can however, do it via JNI. If that is what you had in mind then look at http://www.goto.info.waseda.ac.jp/~fujii/jpcap/index.html
If this isn't what you are looking for then provide a bit more detail about what you will be monitoring.

Using java to listen for a keypress when the program is not in focus

I want to set up a program where no matter what other program I'm using, when I press Ctrl+F1 my program will take focus and run another function or two. Is this possible and if so how can it be done?
Thanks.

Ok Mr. Smartass...Ok
I'm building a browser that is always open, and when
a user presses Ctrl+F1 (notice, just those two keys,
I don't care what else they press...) the browser
will open up. That way, you don't have to wait for it
to load all the time.You have two ideas here. One is having a universal key map that always gets ctrl-f1 sent to your app. The other is a program that is constantly running so that you don't have to wait for it to open up. The former is not possible (and this is a good thing) As warneria and I have been saying, it is bad design for an app to try to force an OS to implement this kind of feature.
If you're not going to help please don't post at all;
it's a waste of time for both you, me, and anyone
else who may need help on the same subject. Why wouldBelieve it or not, I am helping you.

AJAX producer/consumer and JAVA producer/consumer in same project

I've already successfully integrated and customized the code for both an AJAX and JAVA producer/consumer client in JMS (using ActiveMQ as the JMS broker and Tomcat as the webapp container). While both have been working well in separate projects, unfortunately, I'm having a bit of trouble trying to integrate them for the purpose of running an AJAX message listener and JAVA message listener in the same project.
What I'm trying to do is have JAVA act as the failover for when the AJAX JMS consumer is not listening (i.e. when the browser is closed). When a browser client opens, the (constantly running) JAVA client can ignore the messages... but... when no browser client is initialized, the JAVA client should respond to the messages on behalf of the AJAX client.
I've tried using a ServletContextListener pattern, which I was hoping would "automagically" launch the JAVA listener via its main method, whenever the Servlet gets initialized (i.e. it would auto-start when Tomcat gets restarted, or, anytime the Servlet gets redeployed) but it seems Tomcat is not thread-safe and this might be causing some problems.
In any case, I can't seem to get the JAVA client to reliably start running and stay running for the lifetime of my AJAX client (webapp .war), and without including them in the same project and same J2EE container sharing the same ServletContext, I don't know how its possible to ensure they are running and starting and stopping at the same time.
Is there perhaps a better way to accomplish this?

How can I Listen to the File changes?

Hi all,
I am confused in this problem.
How can I make my program listen to the changes in a file. File is not opened in java program, but it is a outside file.
User is not concerned with java program. User opens a file by double clicking and changes something in file. I want to make my java program listen to the file.So program keeps running. So whenever user changes data in that file, my java program should be notified.
Please help me.
Thanks

I guess there are a couple of options.
The full-java version is writing an application that opens said file every n seconds on a timer, and compares it against a cache for changes.
Option two is jni.

Error Stack 1 when running external java function

Hello,
I defined 1 item that contains an external java program.
When I launch the process, i receive following error on the
Java agent listener screen :

and the status remains deferred.
Running the background engine does not change the status of the item. It remains deferred. Anybody has any idea of what is happening ?
grtz,
Chris.

I remember rec. similar errors.
If you are writing a simple code based on the code shown in the workflow guide, looks like you have included some statements which are invalid at run time. examine your code and try to remove all unnecessary statements. write a very simple piece of code by just inserting only the required statements and the error will vanish.
hope this helps

Can i write on perl in java?

can i write on perl in java?

can i write on perl in java?Listen Sscotties, not to step on too many of your toes, but if you are going to answer the question, do it write. He did not ask how to write perl, but how to write on perl. So here is the REAL answer:
public class IThinkThisIsHowWeWouldWritePerlInJava{
public static void main(String []args){
System.out.print("on perl"); // not 100% sure though, maybe someone else could help
}
