Exactly how to run sample Applets

First, let me say exactly what I have done: I unzipped the Solaris version of the Java Card Development Kit on my machine. I then downloaded and unzipped the walletdemo. I opened two terminals and in one typed: jcwde -p 9025 jcwde.app and got the appropriate message. In the other, I typed: apdutool walletApp.scr and got: Exception in thread "main" java.lang.NoClassDefFoundError: javax/comm/PortInUseException. What does this mean? I don't have the regular JDK installed, does that matter? How do I run one of the sample applets that came with JCDK?
Thanks

Hello ! Did you compiled the Wallet.java File ya you need java 1.3 for running the .java file .

2) According to the code I have to specify PIN number when I
install it. Is PIN different from PIN in the card?
Is it application dependent?
private WalletApp (byte[] bArray, short bOffset, byte bLength){
          pin = new OwnerPIN(PIN_TRY_LIMIT, MAX_PIN_SIZE);
          // bArray contains the PIN initialization value
          pin.update(bArray, bOffset, bLength);
          // register the applet instance with the JCRE
          register();
     } // end of the constructor
Anyone can help?
I really appreciate your help

Please suggest solution for it?

I am trying to run the Applet in Tomcat server,
Could you post the code where you invoke the Applet? It sounds like you're saying you're trying to run the Applet as part of your server-side code. The other interpretation is that you are simply accessing the Applet through the browser that happens to be on the machine being used as the server.
Like I say, post the code that shows how you're trying to use the Applet "on the server".

How to run an applet with .java files in 2 dirrerent directories ?

I have an applet with :
5 .java class files and its .html file in one directory and
2 .java class files ( with identical names) and its .html file in another directory .
How do I go about executing this applet ? In the past all the applets
I have run had all the classes in one directory.
Thank you in advance

If you want them both in the same page, put both applet tags in 1 page,
I could do that but both directories have a SpaceDunes.class
and both directories have a Shot class (diffferent immplementations
but the same name)
so the applet tag
<APPLET CODE="SpaceDunes.class"
CODE="SpaceDunes.class"
This can't be the right approach ? ?
Thank you for your advice

Sorry if i sound foolish how to run an applet through a java application

I am into java from last one month ank keep on exploring it in the want to
recently i created a application cum applet in the same class like
applet is doing its own task and there is a main method in the code
that does entirly different task lets assume displaying *'s on the dos prompt the program is getting complied and belive it its running as desired
but the only problem that i m facing if i use appletviewer Myclass.java

it tryied different ways to do it but was not succesful
please do not get irreated if its bizzered but if you really have a solution for it .i will appreciate it
thanking you

Yes you can run an Applet from an application. The magic bit is providing an AppletContext and AppletStub!
Here's how you start it:
        wpa = new WayPointsApplet(this);
        new AppletWrapper(wpa, 380, 320);Here's the class definition: (includes code for my application that can be ignored.
// Define a wrapper class for the applet
class AppletWrapper extends Frame implements AppletStub, AppletContext {
    Applet applet;
    // Constructor
    AppletWrapper(Applet a, int x, int y) {
          applet = a;
          setTitle(a.getClass().getName());
          setSize(x, y);
          Dimension ss = Toolkit.getDefaultToolkit().getScreenSize();
          setLocation((ss.width-x)/2, (ss.height-y)/2);
          add(a, "Center");
          a.setStub(this);
          // Trap window closing
          addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent we) {
                // Test if Write left undone before exiting???
                if(WayPoints.wpa != null) {
                  if(!WayPoints.wpa.okToExit())
                     return;           // Ignore
                applet.stop();
                applet.destroy();
                if(WayPoints.debug || WayPointDefs.plot_debug) {
                  SaveStdOutput.stop();
                System.exit(0);         // EXIT Program
          }); // end WindowListener
          a.init();
          show();
          a.start();
   } // end constructor
    // AppletStub methods
    public boolean   isActive() { return true; }
    public URL       getDocumentBase() { return null; }
    public URL       getCodeBase() {

            if (WayPoints.debug)
                return "YES";
            else
                return "NO";
        if(name.equals("PLOTDEBUG"))
            return (WayPointDefs.plot_debug ? "YES" : "NO");
        if (name.equalsIgnoreCase("SERVER"))
            return "NO";
        return "";
    public AppletContext getAppletContext() { return this; }
    public void      appletResize(int width, int height) {}
    // AppletContext methods

Urgent: How to run Multiple Applets from a URL

Hi,
I am developing an applet that needs memory more than 64MB and I have used -Xmx to set it to 128 MB.
On my web page, I have 3 applications that use the same JAR file of the applet, but the problem is all applets are opened/loaded in same heap space by JVM. So, when I load first applet, it uses 80 MB and when I start 2nd applet, after using 40 MB, it throws OutOfMemory exception.
Is there a way to start each applet with fresh 128 MB heap space rather than all applets sharing 128 MB heap space?
Thanks,
Ajit

That's some hefty requirements for an applet. I believe that the only way to do the Xmx thing on the client side is to have them manually add it in the JVM arguments section of the Java Plugin Control Panel.
The browser/plugin is going to use the same JVM to run all 3 applets in a page. I've never seen a way to tell it to do otherwise. The only separation is the applet contexts, but that is more of a security manager grouping thing.
Maybe you should look into how you can better manage your data so you don't need so much memory.

HOW TO RUN THE APPLET IN JAR?

Hi,
I have an simple applet . I have created the jar file for the applet using the jar utility.

As an Applet does not have a method main, then obviously you need to convert it to an application, which does.

How to run an applet with JDBC connectivity on a web browser

I've created an Applet in Java with SQL connectivity...i.e. it retrieves certain data from a table in SQL and puts in the TextField.....
Now, the problem is that this Applet works in NETBEANS....but fails to work when I use a web-browser..or the "appletviewer" command....
It says that it doesn't have permission to access local files....On Research, i've found that it is somethin' related to the concept of "Signed Applets", "Permissions" & "Security Policies" in java which doesn't allow any applet (without Certificate) to access Local Files.....
Can Somebody please tell how to overcome this problem.....?

I'm going to be blunt with you. You are most likely going to have to redesign your application from scratch. And if it turns out you don't have to then you should anyway because it's a bad idea and fraught with peril.
Anyway here the major touchpoints on this discussion. You can be the judge of how these various points apply to you.
- Applets are restricted. - Yes Applets have a number of security restrictions on what they can or cannot do. This is designed to protect users from malicious applets. By signing your applet you can request permission from the user to do certain activities that are otherwise restricted. But not all.
- If you are using the JDBC-ODBC bridge then you need a different driver. If you sign your applet it might work in some limited scenarios but it will be hairy and is discouraged.
- If you are using Access or another file based database (CSV Excel etc) then you are doomed. You'll have to get yourself a different database. A non file based one. It doesn't matter if you sign your applet or not. You're still doomed.
- If you are trying to connect to a database server that is not at the same physical address as your web server you are doomed. Signing the applet will not help
- Connecting directly to a database from an applet is extremely risky business. Starting with now anyone can steal your username and password for your database quite easily.
What you should do in the redesign is put all the database accessing code in a Servlet. This Servlet does not have to be Java, it could be PHP, Perl, ASP, etc. It doesn't matter. Just put it on the server side. Then have your applet connect to this code via a webservice to do what is required.

Exactly how to run sample Applets
