Listener implementation
Recently I decided to learn the GUI development in java and I am using the online tutorial avialble in Sun's website.
For the practice, i decided to implement a notepad for a foreign language.
This is what I am trying to do.
In the notepad the user types with the romanji and it gets automatically changed to the appropriate character of the language.
For example, lets say if i type 'ma' then it will show some character pronounuced 'ma' in other language.
I am using the JTextArea for typing. and this is how i plan to convert
to the language. I keep a key for the input method and the languages
corresponding unicode. So when a match is found that match is converted.
However, I am stuck with how to get those characters for conversion.
I tried using DocumentFilter, KeyListener but i found it little difficult to adjust the offset and lengths etc.
Is there a better way of doing it? and what kind of listeners is better?
If someone could some me the direction on how to achieve it, I would be grateful.
Thanks.
Hello,
sounds as if you would like to translate Latin characters (sound) to a Japanese script. Well, my first idea is just to switch the keyboard language (after installing the appropriate language support). In windows this can be quickly done in the systray.
If this is no solution, could you please be more specific as for
I tried using DocumentFilter, KeyListener but i found it little difficult to adjust the offset and lengths etc.I suppose there will be "Latin" (sub)strings of different lengths denoting one character of the target language. Then a buffering of the input is necessary.

Extendable event/listener hierarchy - alternatives to double dispatch?
In the course of a research project we are currently implementing an event based integration framework. We would like to offer an event hierarchy that should be extendable by the user through inheritance. Also, the user should be able to implement and register event listeners that offer a number of overloaded methods to handle different incoming event types, including the user defined ones. The event listeners are also inherited from an existing listener hierarchy. We want to allow for the user to implement handler methods for only selected subtrees of the event hierarchy, leaving the rest to the default listener implementation.
We would like to avoid using reflection in order to keep the code portable to C++.
In a first approach, we tried to solve this using double dispatch, which does not work due to the extendability of the hierarchy. The new event types would need to be added to the base listener interface.
Currently, we are thinking about implementing a table based dispatching, that requires the user to register new event types before using them. But this might become a bit complicated, as we would like the dispatching to respect the inheritance hierarchy (but not use reflection).
Since this will be an essential part of the framework, which can not easily be changed, we would be glad to hear your opinion what might be the best approach to this problem. Are there any new features in the Java language we have missed, that might allow to use double dispatch here (e.g. generics)? Are there any generic approaches to table based dispatching, that avoid reflection? Are we totally missing something else?
Thanks a lot in advance,
JanHi,
to do so, you need to declare those fields in the form CREATE_HIERARCHY.
For example, to add FLDATE node, you should do:
ON CHANGE OF LS_SFLIGHT-CARRID.
PERFORM ADD_CARRID_LINE USING LS_SFLIGHT
CHANGING L_CARRID_KEY.
ENDON.
ON CHANGE OF LS_SFLIGHT-CONNID.
PERFORM ADD_CONNID_LINE USING LS_SFLIGHT
L_CARRID_KEY
CHANGING L_CONNID_KEY.
ENDON.
ON CHANGE OF LS_SFLIGHT-FLDATE.
PERFORM ADD_FLDATE_LINE USING LS_SFLIGHT
L_CONNID_KEY
CHANGING L_FLDATE_KEY.
ENDON.
ON CHANGE OF LS_SFLIGHT-PRICE.
PERFORM ADD_PRICE_LINE USING LS_SFLIGHT
L_FLDATE_KEY
CHANGING L_PRICE_KEY.
ENDON.
and then create the new FORMS PERFORM ADD_PRICE_LINE and
PERFORM ADD_FLDATE_LINE by copy of the existent
PERFORM ADD_CONNID_LINE and change the L_NODE_TEXT in the form.
I suposed you are new to ALV's, so i have a sugestion for you.
Instead of CL_GUI_ALV_TREE try to use some examples of CL_GUI_ALV_TREE_SIMPLE. It's much more simple to understand and to work with. For example Report BCALV_TREE_SIMPLE_DEMO.
In this case, to add more nodes to the the you just need to add 3 lines of code in
perform build_sort_table.

Hi
I am looking at subscribing to network events and working out event ids and things and so far haven't been able to work out this. Fairly simple question, hopefully the answer is just as simple.
Can I subscribe to an event which lets lets me listen for any layer changes (in my iOS app)? The docs suggest any actionable event can be listened for, but I am yet to work out how to do this.
Thanks.If you're using a web front end I don't see how that's possible unless you have persistent connections and "push" technology. HTTP is a request/response protocol, which doesn't lend itself to this problem.
If you're writing a Swing client you have a bit more control.
Maybe one way to do it would be to use JMS publish/subscribe. When a client connects to the server, it subscribes to the database change topic. Whenever one of the registers clients makes a database change, the DAO puts a message on the topic, which is then broadcast out to all registered subscribers. They can update themselves in their onMessage() listener implementation.
Could be a network traffic nightmare if you have a lot of clients. And what about transactions? Will you make the topic and the database transaction a single unit of work?
Might be more complicated than it's worth, but that seems to be your requirement. Not a trivial problem.

Re: timeouts and ExternalConnection
Tim,
Use a Timer class of Framework library to have an explicit control over
the connection. If the end-of-stream marker is not received within a
specified interval of time, handle the situation.
ExternalConnection class does not have any timeout feature of its own,
but it would be a good idea to have one in future.

Subject: timeouts and ExternalConnection
I am working on a Forte service that uses a socket listener (implemented
using the ExternalConnection class) to handle incoming messages. The
messages vary in length, so the code for processing each connection
loops until it finds an end-of-stream marker. If some client is
erroneously sending messages without the marker, it'll loop forever. I
would like the connection to time out if it doesn't receive any valid
messages within a fixed length of time. Is there some functionality
I've overlooked in ExternalConnection that would handle this? If not,
does anybody have an example of a good way to implement it?
Thanks in advance,
Tim

Can not add a picture to the JFrame from an ActionListener class
As topic says, I can not add a picture to the JFrame from an ActionListener class which is a class inside the JFrame class.
I have a Map.java class where I load an image with ImageIcon chosen with JFileChooser.
I my window class (main class), I have following:
class OpenImage_Listener implements ActionListener
public void actionPerformed(ActionEvent e)
int ans = open.showOpenDialog(MainProgram.this); // "open" is the JFileChooser reference
if(ans == open.APPROVE_OPTION)
File file = open.getSelectedFile();
MainProgram.this.add(new Map(file.getName()), BorderLayout.CENTER); // this line does not work - it does not add the choosen picture on the window,
//but if I add the picture outside this listener class and inside the MainProgram constructor, the picture apperas, but then I cannot use the JFileChooser.
showMessageDialog(MainProgram.this, fil.getName() ,"It works", INFORMATION_MESSAGE); // this popup works, and thereby the ActionListener also works.
}So why can�t I add a picture to the window from the above listener class?The SSCCE:
Ok, I think I solved it with the picture, but now I cannot add new components after adding the picture.
Look at the comment in the actionlistener class:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
public class Test extends JFrame{
JButton b = new JButton("Open");
JFileChooser jfc = new JFileChooser(System.getProperty("user.dir"));
Picture pane;
Test(){
super("Main Program");
setLayout(new BorderLayout());
JPanel north = new JPanel();
add(north, BorderLayout.NORTH);
north.add(b);
b.addActionListener(new Listener());
setVisible(true);
setSize(500,500);
pane = new Picture("");
add(pane, BorderLayout.CENTER);
class Listener implements ActionListener {
public void actionPerformed(ActionEvent e){
int ans = jfc.showOpenDialog(Test.this);
if(ans == jfc.APPROVE_OPTION)
File file = jfc.getSelectedFile();
Test.this.add(new Picture(file.getName()), BorderLayout.CENTER);
pane.add(new JButton("NEW BUTTON")); // Why does this button not appear on the window???
pane.repaint();
pane.revalidate();
public static void main(String[] args)
Test t = new Test();
class Picture extends JPanel
Image pic;
String filename;
Picture(String filename)
setLayout(null);
this.filename = filename;
pic = Toolkit.getDefaultToolkit().getImage(filename);

Hello,
My instructor is wanting me to use the MVC paradigm. He was telling me that I should be able to put my deal() method in my Model.java. How can I access paintComponent() from the Model.java? If I put the deal() method in the View.java, then it is fine. I have been racking my brains all day long with this. Can anyone please take a look and let me know what I am doing wrong?
Thanks,
E

_deckFront[i] = _deckFront[randomPosition];
_deckFront[randomPosition] = temp;
}//===============================================================end method shuffle
}//=============================================end class NewSolitaireModelI would have deal() in the model. I think that's where it belongs, because deal() should probably be distributing the cards in some random manner into some container (abstractly speaking). The view can then get the cards from that container when it's notified that the deal() happened...
public class DeckModel {
private List listeners = new ArrayList();
private List available = new ArrayList();
private List played = new ArrayList();
public void deal() {
// take all cards, shuffle them, put them into "available"
fireCardsShuffled();// listeners can then get from available and display them however
public void play(Card c) {
played.add(c);
available.remove(c);
fireCardsPlayed(c);
public void fireCardsPlayed(Card c) {
// notifiy listeners
for(int x = 0; x < listeners.size(); x++) {
((DeckListener)listeners.get(x)).cardPlayed(new DeckEvent(this, c));
public void fireCardsShuffled() {
// notifiy listeners
for(int x = 0; x < listeners.size(); x++) {
((DeckListener)listeners.get(x)).cardsShuffled(new DeckEvent(this, null));
public void addDeckListener(DeckListener dl) {
listeners.add(dl); // maybe have a remove method.
// deck listener, implemented by the view.
public interface DeckListener {
public void cardsShuffled(DeckEvent de);
public void cardPlayed(DeckEvent de);
}Something along those lines. -
Questions on events in a multi-class GUI
I have a GUI application that is constructed as follows:
1. Main Class - Actually creates the JFrame, contains main method, etc.
2. MenuBar Class - Constructor creates a new JMenuBar structure and populates it with various JMenus and JMenuItems. A new instance of this class is instantiated in the Main Class to be used in the setMenuBar() method.
3. ContentPane Class - Constructor creates a vertical JSplitPane. A new instance of this class is instantiated in the Main Class to be used in the setContentPane() method.
4. BottomPane Class - Constructor creates a JPanel and populates it with various stuff. A new instance of this class is instantiated in the Content Pane Class to be used as the bottom pane in the vertical JSplitPane.
5. TopPane Class - Constructor creates a horizontal JSplitPane and populates the left pane with a JScrollPane containing a JList. A new instance of this class is instantiated in the Content Pane Class to be used as the top pane in the vertical JSplitPane.
6. TabbedPane Class - Constructor creates a JTabbedPane. A new instance of this class is instantiated in the Top Pane Class to be used as the right pane in the horizontal JSplitPane.
7. DisplayPane Class - Constructor creates a JPanel. A new instance of this class is instantiated in the Tabbed Pane Class as the first tab. The user has the ability to click at points in this pane and a dialog box will pop up prompting the user for a string. Once the user enters something and clicks "OK", an instance of a custom Java2D component that I've created will be added to the DisplayPane where the user had clicked, with the string the user inputted being used as its name. The user can then drag the component around, enter a key combination to display all the names, etc.
8. Custom Java2D Component Class - Constructor creates my custom Java2D component. Instances of this are added to the Display Pane Class, as I have described.
Now, originally, I was going to ask "How do you work with events between these multiple classes?" but I have solved half of that problem myself with the following class:
9. Listener Class - A new instance of this class is declared in the constructor of the Main Class, and is thus passed down through the GUI hierachy via the constructors of the various classes. I then use the addActionListener() method on various components in the other classes, and then the Listener Class can capture an event using the getActionCommand() method to figure out what fired the event.
So that covers the "How do I capture events in multiple classes?" question. Now I'm left with "How do I affect changes on those classes based on events?"
For example: In my MenuBar class, I have a "Save" menu item. When this is clicked, I want to declare a new JFileChooser and then use the showSaveDialog() method, which throws up a dialog for saving a file. The problem is, the showSaveDialog() method takes a Component which is the parent frame. Obviously the Listener Class is not a frame. I want to use the Main Class as the parent frame. How would I do this sort of thing?
Another example: In my MenuBar class, I have a "New" menu item. For now, I want this to invoke a method in the DisplayPane Class that erases all of my custom Java2D components that have been made, thus giving the user a clean slate. How would I give my Listener Class access to that method?
A final example: Every time the user adds one of my custom Java2D components, I want that component's name to be added to the JList that is in my TopPane class. Vice versa with deleting a component: its name should be removed from the JList. How would I listen for new components being added? (A change listener on the pane? One on the ArrayList<> that contains all of the components? Something else?) And, of course, how would I give the Listener Class the ability to change the contents of the JList?
One idea I've come up with so far is to instantiate a new instance of each of my GUI classes in the Listener class, but that doesn't really make much sense. Wouldn't those be new instances that are totally separate from the instances the rest of my program is using? Another thought is to make the Listener Class an internal class inside the Main Class so that it can use the accessor methods of the GUI classes, but a.) I would like to avoid stuffing everything in one class and b.) this brings up the question of "How would I get an accessor method that is in a class that is two or three deep in the hierarchy?" (.getSomething().getSomethingInsideThat().getSomethingInsideTheInsideThing()?)
Help with answering any or all of my questions would be much appreciated.Hrm. At the moment, for my first attempt, I'm doing something similar, it just strikes me as quite unwieldy.
Start of Listener class, with method for setting what it listens to. (I can't use a constructor for this because the MenuBar and the ContentPane take an instance of
this Listener class in through their constructors. You can't pass the Listener in through their constructors while simultaneously passing them in through this
Listener's constructor. That would be an endless cycle of failure. So I just instantiate an instance of this Listener class, then pass it in through the MenuBar and
ContentPane constructors when I instantiate instances of them, and then call this setListensTo() method.)
public class Listener implements ActionListener
private MenuBar menuBar;
private ContentPane contentPane;
public void setListensTo(MenuBar menuBar, ContentPane contentPane)
this.menuBar = menuBar;
this.contentPane = contentPane;
}The part of my actionPerformed() method that does some rudimentary saving, which I will make more complicated later:
else if (evt.getActionCommand() == "saveMenuItem")
JFileChooser fileChooser = new JFileChooser();
int returnVal = fileChooser.showSaveDialog(menuBar.getTopLevelAncestor());
if (returnVal == JFileChooser.APPROVE_OPTION)
File file = fileChooser.getSelectedFile();
ArrayList<Node> nodes = contentPaneClass.getTopPaneClass().getTabbedPane().getDisplayPane().getNodes();
try
BufferedWriter out = new BufferedWriter(new FileWriter(file));
for (int i = 0; i < nodes.size(); i++)
Node node = nodes.get(i);
out.write(node.getIndex() + "," + node.getXPos() + "," + node.getYPos() + "," + node.getName());
out.newLine();
out.close();
catch (IOException e)
//To be added
}That part that seems unwieldy is the
ArrayList<Node> nodes = contentPaneClass.getTopPaneClass().getTabbedPane().getDisplayPane().getNodes();The reason I'm using a separate Listener class is because if I put, say, the actions for the MenuBar in the MenuBar class, and then want to save stuff in the JPanel
at the bottom of the hierachy, I would have to go up from the MenuBar into the JFrame, and then back down the hierachy to the JPanel, and vice versa. Kind of like
walking up a hill and then down the other side. I imagine this would be even more unwieldy than what I'm doing now.
On the plus side, I am making progress, so thanks all for the help so far! -
Login issue in OIM11g due to oim credsmap error
We have OIM 11gR2PS1 installed on unix box. We have AD connector 11.1.1.5.0 installed on it .Also,peoplesoft recon connector PSFT_ER-11.1.1.5.0 is installed
In our scenario,we have webservice code in which using recon event we are creating users in OIM environment
This is hosted on same OIM server unix box.Inside webservice code we have refred oimclient.jar file to work with OIM APIs and Recon Service class.
When i tested webservice for first time it was unable to load OIM API classes as it was unable to find oimclient.jar in classpath.
So to resolve this issue i kept oimclient.jar in location- "WL_HOME/server/lib/" and also added following entry in setDomainEnv.sh to load oimclient.jar explicitly in classpath
CLASSPATH="WL_HOME/server/lib/oimclient.jar:${CLASSPATH}"
export CLASSPATH
and made entry in system-jazn-data.xml present in DOMAIN_HOME//config/fmwconfig/ as :
<grant>
<grantee>
<codesource>
<url>file:${domain.home}/servers/oim_server1/stage/*</url>
</codesource>
</grantee>
<permissions>
<permission>
<class>oracle.security.jps.service.credstore.CredentialAccessPermission</class>
<name>context=SYSTEM,mapName=oim,keyName=*</name>
<actions>read,write</actions>
</permission>
</permissions>
</grant>
After this change, webservice was working as expected and OIM related things were working fine.
But,when we tried to run schedule task "Active Directory Group Lookup Recon" for AD, we are getting error message as :
java.lang.LinkageError: loader constraint violation: loader (instance of com/thortech/xl/dataobj/tcADPClassLoader) previously initiated loading for a different type with name "com/thortech/xl/dataaccess/tcDataProvider"
So,to resolve this AD schedule task issue,we rolled back changes made for webservice in setDomainEnv.sh and system-jazn-data.xml file
and removed explicit classpath entry line of oimclient.jar from setDomainEnv.sh
But after restrating all admin and managed servers,we are currently facing issue in logging into OIM idenity/syadmin or design console with xelsyadm credentials
we have never made any changes of password for xelsyadm account or not made any change in any authenticatorproviders in weblogic console
we tried everything form reverting all changes to original setup without webservice or peoplesoft listener implementation
removed all explicit classpath entries or grant entry for oim credsmap from system-jazn-data.xml.
But still same issue persists
Any helpful suggestion is appreciated on this ASAP.

... 72 moreHi All,
I have tried out option of adding authwl.conf in java argument as mentioned. But,still same issue persists. I think it will be same whether we refer authwl.conf file from OIM_ORACLE_HOME/server/config or OIM_ORACLE_HOME/designconsole/config/ location.
We havent made any changes in USR table for xelsysadm user
Even system-jazn-data.xml is intact.
Actually,when i removed following classpath entry from setDomainEnv.sh file
CLASSPATH="WL_HOME/server/lib/oimclient.jar:${CLASSPATH}"
export CLASSPATH
Its working fine and i am not facing any login issue in OIM console.Also the Active Directory connector scheduled task are running fine without giving earlier error whic is becaus of explicit classpath addition in setDomainEnv.sh.This error was
java.lang.LinkageError: loader constraint violation: loader (instance of com/thortech/xl/dataobj/tcADPClassLoader) previously initiated loading for a different type with name "com/thortech/xl/dataaccess/tcDataProvider" .
This error was arising since i have explicitly mentioned oimclient.jar again in classpath and as OIM server also will load it at OIM server startup time. So it was finding two instance of tcDataProvider and was not able to decide to refer to which one of them.
But, I have to refer oimclient.jar in my webservice code to work.If we dont add classpath entry explicitly for oimclient.jar then it will throw error..that it is unable to load OIMClient class.
Webservice is deployed in OIM serveer . Is there any other way by which i can refer oimclient class in webservice code without causing this classpath conflict issue. ?
Also.is it correctthat for first time when we load Classpath explicitly like i did in my scenario,then it will always try to refer same classpath for that jar always.
For ex: in my env i made changes in setDomainEnv.sh and modifed classpath enrty as :
CLASSPATH="${OIM_ORACLE_HOME}/server/client/oimclient.jar:${CLASSPATH}"
export CLASSPATH
but this time it will start throwin the exception as :
<Nov 11, 2013 11:24:24 PM EST> <Error> <XELLERATE.ACCOUNTMANAGEMENT> <BEA-000000> <Class/Method: tcDefaultDBEncryptionImpl/initKeyStore encounter some problems: access denied ("oracle.security.jps.service.credstore.CredentialAccessPermission" "context=SYSTEM,mapName=oim,keyName=.xldatabasekey" "read")
java.security.AccessControlException: access denied ("oracle.security.jps.service.credstore.CredentialAccessPermission" "context=SYSTEM,mapName=oim,keyName=.xldatabasekey" "read")
Do i need to reinstall OIM setup to resolve this issue or is there any other way to refer oimclient.jar in my webservice code deployed in OIM env ?
Please suggest.
Thanks,

How to keep filename in textfield when filter is changed in a filechooser
Hi, guys,
I met a problem to keep filename in textfield when filter is changed in a filechooser
for example, a JFileChooser has two filters
*.jpg
*.png
Before I open JFileChooser, I used setSelectedFile(File) to set "aaa.jpg" as default name in textfield.
when I change the filter to "*.png, ", I want to change the text in textfield to "aaa.png", Actually, I used setSelectedFile(File), If there is an existed file named "aaa.png", this file will be selected on fileView, but the name will not be shown on the textfield. Anybody has ideas?
Thanks in advanced.I really thank you for your answer, but it seems you misunderstand what I said because of my poor english..
what I said is:
after you open the filechooser, the filechooser has a combobox to choose file filter and a field to show filename.
what I want is:
when you open the filechooser, initial name in field is "test. jpg"
change filter, "test.jpg" will be change to "test.gif" in the field.
I don't want to close the filechooser.
That's why I used a listener to listen JFileChooser.FILE_FILTER_CHANGED_PROPERTY event.
and I modified your codes
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import java.beans.PropertyChangeListener;

JPanel p = new JPanel(new GridLayout(1, 2));
p.add(btnShow);
getContentPane().add(p, BorderLayout.SOUTH);
pack();
fc.addPropertyChangeListener(new Listener(fc));
fc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
fc.setAcceptAllFileFilterUsed(false);
fc.setFileFilter(new ExtensionFileFilter(".gif"));
fc.addChoosableFileFilter(new ExtensionFileFilter(".jpg"));
defaultFile = defaultFile.equals("") ? "Test.jpg" : "Test.gif";
fc.setSelectedFile(new java.io.File(defaultFile));
btnShow.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
fc.showOpenDialog(Testing.this);
public static void main(String[] args) {
new Testing().setVisible(true);
class ExtensionFileFilter extends FileFilter {
String fileTypes = "";
java.util.List extensions = new java.util.ArrayList();

fileTypes = ft;
public String getDescription() {
return fileTypes;
public boolean accept(File f) {
if(f.isDirectory()) return true;
if (f.getName().endsWith(fileTypes)) {
return true;
return false;
class Listener implements PropertyChangeListener {
JFileChooser fChooser = null;
Listener(JFileChooser fChooser) {
this.fChooser = fChooser;
public void propertyChange(PropertyChangeEvent evt) {
if (evt.getPropertyName().equals(JFileChooser.FILE_FILTER_CHANGED_PROPERTY)) {
FileFilter fileFilter = (FileFilter) evt.getNewValue();
if (fileFilter != null) {
String fileName = null;
if (fileFilter.getDescription().equals(".jpg")) {
fileName = "Test.jpg";
} else if (fileFilter.getDescription().equals(".gif")){
fileName = "Test.gif";
String newFileName = "C:\\" + fileName;
fChooser.setSelectedFile(new File(newFileName));
}Thanks again.

I'm about desperate because i spent 3 days on this and i'm am in dire need for help!
1. First i want to create a GUI that it a quiz.
2. Create Questions by using Combo Box
3. Next it creates a text field and allow me to input my answer
4. following that, after the input is inputted, i click a button that says check answer and it will return if it is correct or false.
The problem is that code is so messed up that i don't know where to go.
When i run it, it show me a combo box with 3 questions but before i even answer it, it shows that i'm incorrect.
Thats why I can't really brief wat i need help in. So, could you write a quick code that can summarize the whole thing. You can use my code and fix it up. Thanks very so much!

Java Media Framework + jipCam + IP Cam
Hi everyone,
I maked an aplication using JMF, its connect to a USB cam and shouw the video, it's can snapshot the video too.. and record the video. Now i'm studding a JMF integration with a IP CAM, using the jipCam [http://jipcam.sourceforge.net]
But, i having some difficulty to do it.
Someone here has axperiency with jipCam?
My main question is how to prepare the MediaLocator using jipCam.
Thanks, and sorry the poor english language..
---- portuguese version
Sauda��es,
Fiz um aplicativo utilizando JMF que se conecta a uma camera USB e exibe sua imagem, podendo tirar 'fotografias' da imagem e/ou gravar o v�deo. Agora estou estudando a integra��o do JMF com uma Camera IP, para tanto estou estudando o jipCam http://jipcam.sourceforge.net/ que � um framework que auxilia exatamente neste tipo de comunica��o: conectar uma camera ip em um aplicativo jmf. Por�m, estou com dificuldades para encontrar documenta��o, ou c�digo de exemplo, nem se quer um Hello World encontrei.. Em fim, algo que facilite minha vida. Algu�m j� trabalhou, ou estudou algo a respeito?I build a simple code to play a IP Cam:
But i have the fallow error:

this code can work with an local cam or a local file. you only need to substitute the MediaLocator and the DataSource settings in the main method:
using jipCam (the current main code):
public static void main(String[] args) {
MediaLocator ml = new MediaLocator("http://192.168.0.100:80");
net.sf.jipcam.axis.media.protocol.http.DataSource ds = null;
try {
// DataSource configuration
ds = new net.sf.jipcam.axis.media.protocol.http.DataSource();
ds.setLocator(ml);
// i'm not using password
ds.setUsername(null);
ds.setPassword(null);
} catch (Exception e) {
System.err.println("Impossp�vel criar dataSuource para: " + ml);
e.printStackTrace();
PlayerManager p = new PlayerManager();
p.play(ds);
}accessing a local device (new main code):
public static void main(String[] args) {
MediaLocator ml = new MediaLocator("vfw://3"); //use the jmf registry to see the correct location
DataSource ds = null;
try {
// DataSource configuration
ds = Manager.createDataSource(ml);
} catch (Exception e) {
System.err.println("Impossp�vel criar dataSuource para: " + ml);
e.printStackTrace();
PlayerManager p = new PlayerManager();
p.play(ds);
