runtime error 'could not find main class' ?

[ruud00000]

I want to write a simple console application showing the content of two object instances. Following code compiles without error however gives the following runtime error : 'could not find the main class: ConsoleApplication.KlantType. Program will exit.'

If I 'clean an build project' (Netbeans) then I get
Created dir: D:\Java\NetBeansProjects\ConsoleApplication1\dist
Not copying the libraries.
Building jar: D:\Java\NetBeansProjects\ConsoleApplication1\dist\ ConsoleApplication1.jar
To run this application from the command line without Ant, try:
java -jar "D:\Java\NetBeansProjects\ConsoleApplication1\dist \ConsoleApplication1.jar"
jar:
BUILD SUCCESSFUL (total time: 1 second)

If I do that I get following error message on the dos prompt:
Exception in thread "main" java.lang.NoClassDefFoundError: consoleapplication1/M
ain
Caused by: java.lang.ClassNotFoundException: consoleapplication1.Main
at java.net.URLClassLoader$1.run(Unknown Source)

at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: consoleapplication1.Main. Program will exit.

What is wrong? How to solve?

Here's the code:

package ConsoleApplication1;

public class KlantType {

private String Naam;

public KlantType(String naam) {
Naam = naam;
}

public void setNaam(String value) {
Naam = value;
}

public String getNaam() {
return Naam;
}


private static String klantNaam;

public static void main(String[] args) {
KlantType klantObjectInstance1 = new ConsoleApplication1.KlantType("Janssen");
KlantType klantObjectInstance2 = klantObjectInstance1;
klantObjectInstance2.setNaam("Pietersen");

System.out.println("Waarden na toekenning waarde Pietersen aan eigenschap Naam van instance klant2 van Object Klant");
klantNaam = klantObjectInstance1.getNaam();
System.out.println("Klant 1 : " + klantNaam);
klantNaam = klantObjectInstance2.getNaam();
System.out.println("Klant 2 : " + klantNaam);
}

}

Add "public static void main(String [ ] args){}"

You need a main class for the applet to run.

Add "public static void main(String [ ] args){}"

You need a main class for the applet to run.

That's already there ?

See line just above
KlantType klantObjectInstance1 = new ConsoleApplication1.KlantType("Janssen");
KlantType klantObjectInstance2 = klantObjectInstance1;
klantObjectInstance2.setNaam("Pietersen");

System.out.println("Waarden na toekenning waarde Pietersen aan eigenschap Naam van instance klant2 van Object Klant");
klantNaam = klantObjectInstance1.getNaam();
System.out.println("Klant 1 : " + klantNaam);
klantNaam = klantObjectInstance2.getNaam();
System.out.println("Klant 2 : " + klantNaam);

You are trying to run a class namned “consoleapplication1.Main”, you
should run “ConsoleApplication1.KlantType”.

Well actually I just do what NetBeans suggests: at the command prompt I enter
java -jar "D:\Java\NetBeansProjects\ConsoleApplication1\ dist \ConsoleApplication1.jar"

On the other hand if I go to the file KlantType.java in the NetBeans navigator, right click and chose to run the file directly it works well.

Can I also run this KlantType.java file directly from the command prompt (Windows). How exactly?

If I open the file in JavaEditor instead of NetBeans and run it from there I get the following error message in the DOS window. Note that now it DOES try to open the correct (public) class 'ConsoleApplication1.KlantType', however it fails to run:

Exception in thread "main" java.lang.NoClassDefFoundError: ConsoleApplication1/K

cd YOUR_CLASSPATH
java -cp . ConsoleApplication1.KlantType
