what does that mean guys,
does it mean its installed wrong?

and another thing.. when i richt click on java files off the web (where you 'save target as') the files keep saving as HTML files, and not JAVA files, so when i open the files in the editor (I use xemacs editor) it shows the whole webpage html stuff in it too

please help guys, im not sure whats wrong

Have you added the path of the java bin directory to the path enviromental variable of your system? That will make the commands like java, javac recognisable no matter what path you're in the command prompt.

For The first problem:
Check that you have JDK installed on your computer and that "CLASS_PATH" in System Environment Variabels is set correctly to the Java JDK Bin Directory

For the second problem:
This is caused by your browser, check for updates

yep I did all that.. here is what it told me to do in the cd instruction..

Code:

Installing j2sdk (JAVA).
NOTE: Installing Java is a pre-requiste for installing other applications and should be done first.

1. Double click on j2sdk-1_5_0_05-windows-i586.exe
2. Accept the term and conditions, click next.
3. Click "Next>" several times.
4. On your desktop there is an icon called "MyComputer", right click on it.
Select "Properties".
Then the "Advanced" tab.
Select "Environment Variables".
Under "System Variables" select "Path".
Now click on "Edit".
Under "Variable Value" add to the end of the text ;C:\j2sdk1.4.2_05\bin
**Note the semi-colon is important, make sure the path is correct to the java installation bin directory if you changed the installation directory.**
5. Now click on "OK" several times and then reboot the machine.
6. Next double click on java3d-1_3_1-windows-i586-directx-sdk.exe to install Java 3D and click on next several times to install.

---

The new path now looks like this..

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\j2sdk1.4.2_05\bin

i did all the reeboting and stuff, and still no luck.. :confused:

One thing i did notice though is that the java stuff is in Program Files in the C:\

and its telling me to add in ;C:\j2sdk1.4.2_05\bin to the end of the path :confused:

Then correct it by Adding the "\program files\" after "C:"

ok thanks, changed it to this..

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Java\jdk1.5.0_05\bin

still no luck :confused:

actually never mind, i tested a small program and it worked..

Code:

---

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

public final class SimpleGui extends JFrame {

    private JLabel helloL;
   
    public SimpleGui() {
        setTitle("Simple Gui Example");
        setSize(1200,800);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

        Container cp = getContentPane();
        cp.setLayout(null);

        helloL  = new JLabel("Hello");
        helloL.setBounds(200,0,400,400);
        cp.add(helloL);

    } // IFrame constructor

    public static void main(String[] args) {
        SimpleGui i= new SimpleGui();
        i.setVisible(true);
    }

} // IFrame

compiled and i ran it successfully. thanks guys.

now for problem2, ComputerJY, do you know where i check for browser updates from mate?

What is your browser?

microsoft internet explorer 6.0

I hate saying IE doesn't cause this problem
but the problem isn't in "IE"
it's probably in the website you are downloading the java files

yeah you're right, it is the website lol, sorry.

thanks for your help guys, brilliant and swift help!
