Hi Ling,
Try using the classpath option on the compiler opposed to the environment
variable. One problem could be the classpath could have been relative to where
you were on the file system.
> javac -cp ~/workspace/github/johnmay/cdk/dist/jar/cdk-1.5.2.git.jar Main.java
where 'Main.java' is:
> import org.openscience.cdk.*;
>
> public class Main {
> public static void main(String[] args) {
> System.out.println("Using CDK");
> Atom atom = new Atom("C");
> }

You will also need to include other dependencies (see 'cdk/jar/') for certain
tasks.
Now you probably already know this but it all gets very tedious so at some
point you'll need to start using a build system (maven, gradle, ant etc.) or an
IDE. Personally I use IntelliJ IDEA of which there is a also free community
edition, Netbeans and Eclipse are other free options.
Hope this helps,
J
