I updated my JDK to 1.6 in Suse Linux 11.1 and it can't compile even
the simplest of programs.

To check that my default java is correctly set, I ran:
/usr/sbin/update-alternatives --display java

and got:

java - status is auto.
link currently points to /usr/lib/jvm/jre-1.6.0-openjdk/bin/java

followed by a bunch of alternative java installs.
It is set to choose the "best" JDK for the job which is jre-1.6.0-
openjdk/bin/java

Now even the following simple code won't compile properly:

import java.io.*;

public class Hello{

    public static void main(String[] args){
        System.out.println("It works.");
    }

}

when I compile using javac Hello.java.

Every time, it says "undefined reference to 'main'.

Am I invoking it wrong?

Here's the exact error message I get:

/usr/lib/gcc/i586-suse-linux/4.3/../../../crt1.o: In function
`_start':
/usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/i386/elf/start.S:115:
undefined reference to `main'
collect2: ld returned 1 exit status

when I type "javac Hello.java"
