Java "filnavn" notinited

Umiddelbart lyder det som en fejl i appletten.

Har du checket den i appletviewer ?

nej => prøv det

ja => prøv og enable java console i IE og se om den siger noget

i java console i IE står der:

Den har problemer med at finde BoldKasse.class ...

Check HTML koden og BoldKasse.class filens placering i forhold til HTML filen.

fandt lige denne linie:

"load: class BoldKasse.class not found.

java.lang.ClassNotFoundException: BoldKasse.class"...

her er kildekoden til min HTML og .java fil:

JAVA:
----------------
// Eksempel på brug af en variabel
// koden skal være i filen Variabler.java
public class Variabler
{
  public static void main (String[] arg)
  {
    int tal;
    tal = 22;
    System.out.println("Svaret på livet, universet og alt det der: " + tal);

    tal = 42;
    System.out.println("Undskyld, svaret er: " + tal);
  }
}

HTML
-------------------------------
<HTML>


<HEAD>


<TITLE>HTML til Java</TITLE>


</HEAD>


<BODY>


<APPLET CODE="Variabler.class" WIDTH="256" HEIGHT="256">


Denne side kræver Java!


</APPLET>


</BODY>


</HTML>

min fil hedder Variabler.class  .... og det står også i HTML-fiolen.. forstår ikke hvorfor den leder efter BoldKasse.class? :S

Det må være en ældre fejl.

Den seneste fejl er:

java.lang.ClassCastException

    at sun.applet.AppletPanel.createApplet(Unknown Source)

og det fordi din Java kode ikke er en applet men et program !

IE kan derfor ikke typecaste den til en applet.

program også kaldet applikation : køres standalone

applet : embeddes i HTML side og køres af browser

hmm.. hvordan skal jeg så få min class-fil vist?.. (undskyld, jeg er HELT ny ;) )...

Du oversætter med:

javac Variabler.java

Du kører programmet med:

java Variabler

Og du skal ikke undskylde. Alle skal lære fra bunden af - jeg kender ihvertfald
ingen der er født med Java viden.

:-)

Hehe, tak for det ;).. det giver mig lyst til at kæmpe videre med det ;)....

men men men... nu får jeg dene fejl :S... det lyder som om den mangler en main().. ligeson i C/c++ ?? er jeg helt skæv? (kildekoden står i forrige kommentar)

C:\JAVA\jdk\bin>java c:\java\apps\variabler\Variabler
Exception in thread "main" java.lang.NoClassDefFoundError: c:\java\apps\variable
r\Variabler

C:\java\apps\variabler>  C:\JAVA\jdk\bin\java  Variabler

eller:

C:\JAVA\jdk\bin>  java  -classpath C:\java\apps\variabler  Variabler

Hvis du ligger C:\JAVA\jdk\bin in i PATH variablen så kan du nøjes med:

C:\java\apps\variabler>  java  Variabler

hvilket nok er mest handy

Og et svar

WEE :D... tak for det :=)... men hvordan kan man se det som et windue?.. det skal der måske meget mere kode til?.. for så vil jeg ikke spørge om mere ;).. men kan man kun se det i dos?..... anyways.. lig et svar mere;)

Et GUI program skal kodes lidt anderledes.

Et GUI program kan enten startes i console vindue med java kommandoen eller
startes med javaw kommandoen som ikke kræver et console vindue.

Et (meget kedeligt) GUI program:

import javax.swing.*;
import java.awt.*;

public class JBlack extends JFrame {
    public JBlack() {
        getContentPane().setBackground(Color.black); 
        setSize(100, 100);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
    public static void main(String[] args) {
        JBlack f = new JBlack();
        f.show();
    }
}

tusind tak for hjælpen arne_v :D... en sand ekspert ,)
