Classes not found when compiling for jdk1.3.1_01 on red hat 7.2

Question

I have just installed jdk1.3.1_01 (rpm) on linux red hat 7.2
I have written a small program to test, however, the compiler isn't able to locate the classes.
import javax.swing.*;
public class JTest {
public static void main( String args[] )
JOptionPane.showMessageDialog( null, "Hello", "Test Dialog",
JOptionPane.INFORMATION_MESSAGE );
System.exit( 0 );
When compiled it generates the error:
JTest.java:10: error:Variable "JOptionPane" is not defined in current context
I have the path and classpath set to what I think are the correct directory paths.
Any advice would be much appreciated!
Thanks..

Answer 1

Sorry, typo in the classpath... but now when I compile
I get error: "segmentation fault" then nothing else.
This also happens when I execute a precompiled app (eg
"java OldApp").This is to do with GLIBC-2.2, I believe. :/ (Pointed out by Niteen. :)
"ulimit -s 2048" should fix this. Adding this line to /etc/profile or your ~/.profile shall automatically run this command every log in.
