I'm here to collect some information on tools used in Java Card development
Hi All,
Thank you for reading this message, I'm a technician from a software company. We are currently developing softwares based on java card technology. The complicated jcdk configurations and java settings are quite not easy to use. I'm coming here for asking a new set of tools which may help. Can any one give some suggestion?
Hi,
Are you looking for free or commercial tools? Are you developing for smart card or GSM/mobile?
Many of the big card vendors have a commercial tools for developing with their cards. Some are harder to get than others. If you have a specific card vendor in mind you can contact them directly to see what tools they can offer. If your company is planning on purchasing a large number of cards the vendors are usually pretty happy to help out where ever they can.
Another option is to develop a set of scripts or tools around the JCDK.
Cheers,
Shane

Need some OO design pointers for a Java card game I wrote for uni
Hi,
I hope a few of you Java sifus can help me understand I dilemma I keep finding myself in.
I created a card game for a university assignment which works great but its not very OO at the moment.
I only have 3 classes; a Card class, a Deck class and a Game class which contains all my GUI, AI, Game Controller, Player and Hand code.
The assignment is over but I feel like enhancing the game, adding animation, multiplayer, several AI agents etc.
The first thing I have attempted is animation and I've hit a brick wall. I am trying to create animation for my card game whereby I have an animation showing the cards being shuffled and then an animation which shows the cards being dealt to the players. The game then commences. The cards on the GUI then need to be clickable (MouseListeners?) to play the game. If you're running Windows 7, load up 'Hearts' and you'll know what I'm trying to achieve.
I don't understand how the GUI, and Card class need to be seperated so that its good OO.
If I give you a few snippets of code, it might explain the situation:
A snippet of my card class is as follows:
import javax.swing.*;
public class Card extends JLabel //Each card is a JLabel
private int value; //variable for the value of the card
private int suit; //variable for the suit of the card
private ImageIcon frontOfCard; //Displays the image of the front of the cards
private ImageIcon backOfCard; //displays the image of the back of the cards
public Card (int Value, int Suit, ImageIcon front, ImageIcon back)
value = Value;
suit = Suit;
frontOfCard = front;
backOfCard = back;
setIcon(backOfCard); //To make it non-visible when dealt
}As you can see, each card is a JPanel. I've been told by some I shouldn't extend JPanel but rather that I should have a BufferedImage/Image instance variable for each card as the image of the card. The thing is that I need each card displayed on the GUI which can then be clickable. When it is clicked, it is moved from the players hand, into the players move. - There needs to be an animation showing this.
I've got the animation code figured out in terms of how to move 'images' around a screen to make a pleasing animation. The problem is there are no clickable listeners for images, so the Images needs to be inside some container; a widget which can fire events - Hence the reason I have chosen to extend JPanel for my Cards.
and a Deck class, snippet is as follows:
public class Deck extends JLabel //The deck will be shown on the GUI as a JLabel
private ArrayList<Card> standardDeck;
public Deck()
standardDeck = new ArrayList<Card>();
ImageIcon cardBack = new ImageIcon("CardBack.png");
setPreferredSize(new Dimension(90, 135));
setIcon(cardBack);
int cardCount = 0; //This variable counts the cards. Is used to assist in the name generation of the imageicon filename
String str; //the imageIcon constructor accepts filenames as strings so this string holds the filename of the corresponding card image file.
for (int a=0; a<4; a++) //putting the cards into the deck with the specifed parameters
for (int b=2; b<15; b++)
cardCount+=1; //incrementing the card count (the card files are named 1-52 as integers)
str = Integer.toString(cardCount); //Integer is converted to string type before being added to string str variable
str += ".png"; //To complete the image filename, ".png" has to be concatenated to the string.
standardDeck.add(new Card(b, a, new ImageIcon(str), cardBack)); //creating and then adding the cards
}This is how I envisage a new class diagram for my game:
Card class
Game Class <--- Holds a Deck instance, Players instances, and the GUI instance
Player Class <-- Will contains hand 'instances' , but I will not create a seperate 'Hand' Class, I will use an ArrayList.
AI Class extends Player Class
GUI Class
Deck Class <-- contains 52 cards
My question is, how do I show the Cards on the GUI if my Cards are in a Deck and the Deck is held in the Game class?
Please note that there are 52 cards, so potentially 52 images on the GUI, each of which needs to be clickable. When clicked, the cards are moved about, e.g. from the deck to a players hand, from a players hand back to the deck, from a players hand to a players current move hand.
etc
I've read that GUI, program control, and logic should be seperated. If thats the case, what do I have in my GUI class if the Cards (which are JPanels) are held in the Deck class which in turn is held in the Game class?
Any help on this would be greatly appreciated!
I know what I have written may not be fully clear. I find it hard sometimes to fully convey a problem at hand. Please let me know if you don't understand what I've written and I'll do my best to explain further.Faz_86 wrote:

Admirable, and the best way to learn, doing something that interests you.

I don't understand how the GUI, and Card class need to be seperated so that its good OO.
If I give you a few snippets of code, it might explain the situation:
A snippet of my card class is as follows:
Do a quick Google on the model view controller pattern. Your listeners are your controllers. Your JPanel, JButton, etc. are your view. The AI, Player, Card and Deck (and presumably something like Score) are your model. Your model should be completely testable and not dependent on either the controller or the view. Imagine you could play the game from the command line. Get that working first. Then you can add all the bells and whistles for the UI.
import javax.swing.*;
public class Card extends JLabel //Each card is a JLabel
(redacted)
As you can see, each card is a JPanel. I've been told by some I shouldn't extend JPanel but rather that I should have a BufferedImage/Image instance variable for each card as the image of the card. The thing is that I need each card displayed on the GUI which can then be clickable. When it is clicked, it is moved from the players hand, into the players move. - There needs to be an animation showing this.Extending JPanel is fine. As you noted, you need something to add listeners to. However, I would separate things a bit. First, a card really only has a rank and suit (and perhaps an association to either the deck or a player holding the card). The notion of setIcon() is where you are tripping up. The card itself exists in memory. You should be able to test a card without using a UI. Create a separate class (CardPanel or something similar) that has a reference to a Card and the additional methods needed for your UI.
I've got the animation code figured out in terms of how to move 'images' around a screen to make a pleasing animation. The problem is there are no clickable listeners for images, so the Images needs to be inside some container; a widget which can fire events - Hence the reason I have chosen to extend JPanel for my Cards.

str += ".png"; //To complete the image filename, ".png" has to be concatenated to the string.
standardDeck.add(new Card(b, a, new ImageIcon(str), cardBack)); //creating and then adding the cards
}This is how I envisage a new class diagram for my game:
I am not an animation buff, so I will assume the above works.
Card classRemove the UI aspects to this class, and I think you are all set here.
Game Class <--- Holds a Deck instance, Players instances, and the GUI instancePresumably this is where main() resides. It will certainly have a reference to model classes (player, game, deck, etc.) and likely the master JFrame (or a controller class you create yourself).
Player Class <-- Will contains hand 'instances' , but I will not create a seperate 'Hand' Class, I will use an ArrayList.Does a player really have multiple hands? It seems to me more of a one-to-one relationship (or a player has a one-to-many relationship to Card).
AI Class extends Player ClassWhy extend Player? Create a Player interface, then have a HumanPlayer and AIPlayer implementation. Common parts could be refactored out into either a helper class (delegation) or AbstractPlayer (inheritance).
GUI ClassMy assumption is that this class has a reference to the master JFrame.
Deck Class <-- contains 52 cards
Yes. You may end up recycling this class such that a Deck can also function as a Hand for a given player. If there are differences between the two, create an interface and have a Hand and a Deck implementation. Coding to interfaces is a good thing.
My question is, how do I show the Cards on the GUI if my Cards are in a Deck and the Deck is held in the Game class?You need to pass a reference to the appropriate view class. That is how MVC works. The controller receives a request from the view, dispatches to some model functionality you write (such as GameRulesEngine, Deck, etc.) and returns a result to the view (which could be the same view or a different one, imagine someone clicking 'high scores').
Please note that there are 52 cards, so potentially 52 images on the GUI, each of which needs to be clickable. When clicked, the cards are moved about, e.g. from the deck to a players hand, from a players hand back to the deck, from a players hand to a players current move hand.
etc
That is up to you to write the animation code. In principle, you have a mouse listener, and then you take the appropriate rendering steps.
I've read that GUI, program control, and logic should be seperated. If thats the case, what do I have in my GUI class if the Cards (which are JPanels) are held in the Deck class which in turn is held in the Game class?
See above.
Any help on this would be greatly appreciated!
You are welcome.
I know what I have written may not be fully clear. I find it hard sometimes to fully convey a problem at hand. Please let me know if you don't understand what I've written and I'll do my best to explain further.No, you have been doing fine.

I paid for some songs on iTunes using the gift card I got but it also charged my credit card?
So I got a iTunes $20 gift card from a friend and I correctly redeemed the card an I started buying some songs which took away some of the credit of the iTunes account but then a couple days later my credit card was also charged for buying those songs. Is this normal?
None for payment
After establishing the Credit Card account (i.e. after you have made purchases), you can remove the credit card information by editing your payment info, choosing "None".

How to read "Customixed Information" in UME using WebDynpro Java APIs
Dear All
In our Portal UME we have defined 3 custom fields that appear in the "Customized Information"
tab in the standard Portal "Identity Mangagement" application ie:
krb5principalname :
How can I retrieve the custom fields and values using WebDynpro APIs?
I have the following basic code to retrieve the standard user session information, but
do not know how to extend it to extract the values of the custom fields.
Full points will be awarded to whoever answers question with suggestion that works.
Many thanks in advance
MikeHi Mike,
Following code is for just one custom attribute <custom attribute>
String namespaces[] = umeUser.getAttributeNamespaces();
String ns = null;
for (int i = 0; i < namespaces.length; i++) {
if (i > 0)
ns = namespaces[ i ];
String attrNames[] = umeUser.getAttributeNames(ns);
if (ns != null){
if(ns.equals("<name-space>")){
for (int j = 0; j < attrNames.length; j++) {
if(attrNames[j].equals("<custom attribute>")){
Object attr[] = umeUser.getAttribute(ns, attrNames[j]);
for (int k = 0; k < attr.length; k++){
if(!(null == attr[k])|| !(attr[k].toString().length() == 0)){
//attr[k].toString() has the custom attribute value
break;
}else
continue;
}else
continue;
Where <name-space> is the same value you set in config tool or on portal UME configuration.
Config Tool: Global Service Configuration>services->com.sap.security.core.ume.service>ume.virtual_groups.user_attribute.namespace
Portal
System Administration>System Configuration>UME configuration> User Admin UI tab>
Custom attributes of the user profile
Administrator-Managed Custom Attributes: add ;<name-space>:<custom-attribute>

i know i can do with using system commands like dir, ls etc..
But i want to collect this sysem informations with native java api and codes.
Dou you know any java api ?
Please i need help urgent ...There is nothing in Java to do that. The Java language is independent of the os, and doesn't support (many) os-specific attributes.

Some questions about Java card.
Hello, everyone. I am a rookie in Java card. My major focuses in IC design so I have some questions to ask.
1) As I understand, Java card technology is just a platform.So the regular processor can be used for Java card? What we need to do is just software?
2) How to get the Java card license? All the Java card tech file are released to customers. And how much is the license fee?
3) How much one Java card cost?
Thanx.Hi,
1) Yes that's right the only think that you have to bother on a JavaCard is the software part. You will have to develop an applet that you will then download and instanciate in your JavaCard.
2) For any technical specifications and JavaCard SDK, have a look to this URL:
http://java.sun.com/products/javacard/index.jsp
Regarding the licensing, yo may find some information at this URL:
http://www.internetnews.com/dev-news/article.php/70381
3) The cost of a JavaCard depends on the volume, the card manufacturer. I think, the price of a JavaCard for low volume is from 5 to 10 USD. But you better do some enquiry with a card manufacturer.
Regards.

* have you seen [[firefox consumes a lot of CPU resources]]
If this occur in firefox [[safe mode]] there is a problem that needs investigating.
Do not forget to watch the number of instances of ''plugincontainer.exe'' that are open, there is a known bug causing problems with that see [/questions/812618]
Note also you are able to for instance turn off the hardware acceleration, or by setting a preference (''html5.parser.enable;true/false'') turn off the html5 browser ability of Firefox.

Create a new header+item after sync the item some informations are deleted
Hi All,
I have a DO with a backend adapter and 3 bapi wrapper (GetList, GetDetail, Create).
When I create a new instance (header+item) on client side the data are correct in the database. After a sync the instance is also on the client and the Backend but he lost some informations in the item.
For example i create e_top object (header) and t_vehicle object (item) the i added the item to the header an wirte it in the database. In the datebase both tables for header and item are correct filled.
Application Code:----
public void SaveVehicle( java.lang.String Manufacturer, int Driver, java.lang.String Licence_Number, java.lang.String Type ) {
VEHICLE_E_TOP e_top = model.createVEHICLE_E_TOP();
e_top.setLICENCE_NUMBER(Licence_Number);
wdContext.nodeVEHICLE_E_TOP().bind(Collections.singleton(e_top));
wdContext.nodeVEHICLE_E_TOP().setLeadSelection(0);
model.addToVEHICLE_E_TOPs(e_top);
VEHICLE_T_VEHICLES t_vehicle = e_top.createNewT_VEHICLESs();
t_vehicle.setDRIVER_ID(Driver);
t_vehicle.setLICENCE_NUMBER(e_top.getLICENCE_NUMBER());
t_vehicle.setMANUFACTURER(Manufacturer);
t_vehicle.setTYPE(Type);
wdContext.nodeVEHICLE_E_TOP().currentVEHICLE_E_TOPElement().model();
e_top.addToT_VEHICLESs(t_vehicle);
wdContext.nodeVEHICLE_T_VEHICLES().bind(Collections.singleton(t_vehicle));
wdContext.nodeVEHICLE_T_VEHICLES().setLeadSelection(0);
model.commit();
Now when I snyc with the middleware the object is still on the client (1 row in the e_top table and 1 row in the item table) but in the row of the item table all data until the header key(Licence_Number) is deleted. In the Backend there is a new objekt with only the header imformations.
Best Regards,
DirkHi,
there was another post today n a similar issue. I still do not think it is a standard issue - so lets check first if your implementation is correct.
You should have a look on the CREATE BADI in the backend and on the mapping in the DOE. I expect the CREATE handler does not get all informations form the client, cause you missed to do the propper mapping in the DOE on the middleware. Check this first. If you see the data on the client, the client side should be fine. Check the DOE and its mapping and the BADI implementation on the backend.
Hope it helps!
