Javax packages not found for J2SDK 1.5.0

Question

Hi,
I am very new to Java SDK. I just installed J2SDK 1.5.0 beta 2 and installed it on my RedHat 9.0 box with root permission at /usr/local/(java-home)/
I can compile simple applications which do not import extension packages. However, when I try to compile an application importing javax.swing.* , I get the below error message:
Craps.java:9: Can't find default package `javax.swing'. Check the CLASSPATH environment variable and the access to the archives
Craps.java:11: Superclass `JApplet' of class `Craps' not found.
public class Craps extends JApplet implements ActionListener {
The code of this application is correct, coz I can compile and execute it in Windows.
Can anybody help me with this problem?
Thanks!

Hi Joni,
Thank you for the reply!
I've solved the problem with your inspiration of the ClASSPATH. This is for the reference of those who may encounter the same problem as me.
I installed Redhat 9.0 with default settings and those bundled packages (could be normal to many Linux newbies like me :) There is a default java compiler installed, I guess, and it's bundled with gcc. So when I tried to compile my .java files, the javac comand from j2sdk was not involked. Instead, it's the default-installed java compiler that correspended to my command. I guess this is why no matter what I changed in the .bash_profile in my home directory, the j2sdk command javac had not executed.
After I uninstalled this one, and add j2sdk/bin into my CLASSPATH, everything works fine now.
Btw, I found out this problem by simply typing "javac" in the terminal and read the help suggestions that followed.
