Java


I downloaded and installed Java SE SDK 1.4.2 from sun.java.com and installed it, everything was running fine but now I can't seem to be able to run any of my classes. They work fine for me when I run them on computers in my University.

import javabook.*;

class PiTest
{
public static void main(String args[])
{
MainWindow myMainWindow = new MainWindow("Testing");
myMainWindow.show(true);
}
}

Compiling works fine but running this simple program gets the error:

Exception in thread "main" java.lang.NoClassDefFoundError: PiTest

I have no idea why this is happening can anyone help me?

You may have to set your classpath to include the current directory (, ie CLASSPATH=.:$CLASSPATH). This you can do in your .bashrc or in the /etc/profile or from wherever your system loads its environment variables.

remove the predefind /usr/bin/java or in /bin/java

and replace it with j2sdk.../bin/java

creat a symbolic link (you have to be root)

make sure you are in /usr/local/bin

ln -s /usr/local/java/j2sdk..ver/bin/java java

I hope it work. please let me know
