Applet can't be instantiated

I'm trying to run an applet within IE, but it won't work.
The applet is compiled for 1.1, and it works in appletviewer just fine...what could be the problem?

  }Here's the full code for the initialization stuff that goes on the screen...instead of doing it this way, should I make a paint() and redo this in there?

  • Applet can't be instantiated on IE browser.

    I have created an SWING Applet (JApplet). It works fine inside JDeveloper IDE using the Appletviewer but when I deploy it and I try to launch it through the Internet Explorer browser I get the following message:
    "Applet can't be instantiated".
    I'm working with JDeveloper 3.1.1.2
    Can somebody help me out with this? I will really appreciate it.

    In the java console of IE are you getting any class not found errors?
    Please refer to the following URL (Swing Applet Test ) to check whether your browser supports swing classes or not.
    http://java.sun.com/products/jfc/tsc/articles/getting_started/applet_test.html
    Another way to create and run Swing applets in IE or netscape is to use Java Plug-in.

  • IE says that my applet can't be instantiated

    Okay, the applet I've made can be viewed by the appletviewer whereas IE says it can't be instantiated. Is there a problem with regards to inheritance? I've tried using javac -target 1.1 to compile the code and it still didn't work. It does work for my other applets.
    I'm posting the codes for the html and the two files I've made.

    Errmmm... errors?
    How could it have errors when it runs perfectly well with appletviewer? I used the modification you suggested and it did run using appletviewer.
    Better yet, it can be compiled by java. I don't think there are errors, really since that kind of error you stated I feel should be found by the Java compiler, that's where I usually encounter such errors.
    I'm not really sure if it's how I compiled it(Since somebody told me to compile it using javac -target 1.1 ArchiveName.java and it worked on my other projects that don't have inheritance and uses other classes) I really don't have an idea if it was compiled using 1.1 JVM since I only mostly know the principles of Java and not exactly the more advanced parts.
    Besides MyList.java:9 reads like this               
    this.add(str);
    the value i indicates an integer.
    So it's not a String array rather a String object. Maybe something wrong with my post?

  • SEM-CPM: PerspectiveOverview Applet can't be instantiated

    In SEm-CPM, we encountered an error message when running Scorecard Perspective View on the web, but we don't have the same problem in GUI. The error message says:"Perspective Overview can't be instantiated yet." We are actually using SEM3.1 SP21. Actually one of our clients that is using lower support level than we have does not have this problem.

  • Error with signed applet "class can't be instantiated"

    hi,
    I developed an applet to make a ftp connexion to upload files from the local disk and the applet is already signed. At first I compiled it with the 1.4 version and I got (from other computers) the error "class not found". Then I used the target 1.1 option and now I get the error "class can't be instantiated"
    Do I need any additional code?
    I am using all these imports
    import java.applet.Applet;
    import java.applet.AppletContext;
    import java.awt.*;

    go to
    Tools->Internet Options->Advanced
    Look for "Java (Sun)" (normally near Microsoft VM). I uncheck all the Microsoft VM options but am not sure if that is really necessary.
    Also play with Control Panel, you should see "Java Plug-in" in there and be able to configure browsers a bit with that.

  • Applet in ie 5.0: class can not be Instantiated

    Hi!
    My problem is an Applet, which works fine with the appletviewer and with my iExplorer 5.0.
    But when I tried to install my Application (the Applet is part of a J2EE-WebApp) on the tomcat of an other computer, I get the
    "class can not be instantiated"-Error and iE 5.0 only displays a grey box in the size of the Applet. With the appletviewer it works.
    I got the same tomcat, same mySQL and same browser on both computers.
    I also invoked the application running in tomcat on my computer from 2 other computers - on one of them, the Applet was shown, on the other, I only got this grey box.
    The version of the iExplorer was exactly the same.
    What can be wrong?

    Are you sure there is a static method in the Applet class named newAudioChip that takes a URL as an argument?

    Irrespective of the working of your program, I would suggest you remove a lot of weeds and clean the code. That would help you do easier debugging .
    Somethings I can quickly tell are,
    the constructor in AcidRainApplet not useful, Rain implementing Applet not useful, implements KeyListener, ActionListener can be delegated to another class, usage of inner class can be rethinked of delegation can be given a thought. Following code can be thought of :
      class Rain
        private  int x = 0;
        private int y = 0;
        private int sp = 0;
        Rain ()
          reset();
        public int getX() {
          return x;
        public int getY() {
          return y;
        public void setX(int x) {
          this.x = x;
        public void setY(int y) {
          this.y = y;
         public void reset() {
          x = (int) (Math.random () * width);
          y = 0;
          sp = (int) (Math.random () * 5) + 2;   
      }Good wishes,

  • Load:Tutorial.EmpApplet can't be instantiated ERROR

    Hi,
    By following JDevelopment 2.0 tutorial - Database Applet Tutorial
    It was compiled successfully.
    But when It was run, the ERROR occured !
    " load:tutorial.EmpApplet can't be instantiated "
    Anybody know why it happened ??
    Thanks.

    Unfortunately these is a step missing in the tutorial for the
    beta version. This is actually logged as a doc bug. Here is the
    description:
    For the database applet tutorial, you need to explicitly include
    the JDBC classes111.zip file in the deployment archive. It does
    not get pulled in automatically by the dependency checker.
    Instructions for deployment need to instruct users to:
    1. Click the Add File button for the Additions list box.
    2. In the File Open dialog, navigate to and select the
    aurora\lib\classes111.zip file.
    3. Deploy.
    Sorry, Roel.

    Joe,
    Does the version on IE that you are using support Swing 1.1 ?
    Also, I am not sure why it is referring to the absolute path (D:
    \Program Files\Oracle\JDeveloper 2.0.184
    Beta\myclasses\com\sun\java\swing\plaf\metal\MetalLookAndFeel.cla
    ). Does your jar file have this path?
    Regards,

  • Applet can't be instanciated

    Hello,
    I'm trying to deploy an applet since one week, but I have no
    luck. Can anyone help?
    Running the applet from JDeveloper works well (accessing
    Oracle8i with InfoBus).
    I made a jar-archive without excluding any class.
    But when I apply the applet (package25.Applet25) in the browser,
    there is only the message "load: package25.Applet25 can't be
    instantiated".
    JDev hasn't put the class "sun\awt\AppContext.class" into the
    jar-archive, but according to the output of the java console
    window (below), I think "sun\awt\AppContext.class" is necessary,
    isn't it?
    I spent hours in finding "sun\awt\AppContext.class" in the
    archives of Jdev, but I couldn't find it anyway.
    Is there a bug or can somebody help?
    Thanks,
    Josef

    You need to convert your html page to invoke the 1.2 Java
    Plug-in. See http://java.sun.com/products/plugin/index.html for a
    HTML converter. None of the *dep.zip files are needed nor the

    This is not a suggestion, it's a requirement. When you say
    class MyComboRenderer extends JComboBox implements TableCellRendererthe "implements TableCellRenderer" part is a promise that your class will include a method whose signature is
        Component getTableCellRendererComponent(JTable table, Object value,
                                 boolean isSelected, boolean hasFocus,
                                 int row, int column);

  • Applet can get arbitrary objects as a param tag?

    I wonder if I can get an ViewObject(which is in Info table ) as a value of value
    attribute in applet tag. I mean an object in the infotable of jsp containing the
    applet can be a value of value attribute in applet tag.
    I have this question, since I should give a viewobject to applet when I push
    submit button in jsp containing the applet.
    Help! please~

    Hi Sam,
    Instead of point 1, can you try poin 2 to see.
    1.
    <jsp:include page="test2.jsp" flush="true">
         <jsp:param name="fname" value="FirstName"/>
         <jsp:param name="lname" value="LastName"/>
         <jsp:param name="age" value="11"/>     
    </jsp:include>
    2.
    <jsp:include page="test2.jsp?fname=FirstName&lname=LastName&age=11" flush="true"/>
    3. test2.jsp
    <%=request.getParameter("fname")%>
    <%=request.getParameter("lname")%>
    <%=request.getParameter("age")%>
