Thread Pool Executor ( Runnable Class Executing another Runnable Class )

Question

Hi Folks,
I have my main class called ThreadPoolExecutorUser. I have two Runnable classes called XYZ and ABC
in ThreadPoolExecutorUser class I execute the Runnable class XYZ. Which inturn executes Runnable class ABC.
The problem is that the Runnable class ABC is never executed ?. Can some one please explain what I am I doing wrong.

More Description Below :
*public class ThreadPoolExecutorUser {*
ThreadPoolExecutor dude = new ThreadPoolExecutor (.... );
// I Execute the firest Runnable Xyz here
dude.execute ( XYZ );
Now I have two Runnable inner Classes
*Class XYZ extends Runnable {*
public void run () {
s.o.p ( " I am in Xyz Runnable " );
dude.execute ( ABC );
*class ABC extends Runnable {*
public void run () {
s.o.p ( " I am in ABC Runnable " );
}

Hey folks.... Sorry its a typo in my e-mail. Sorry about that. I am pasting the actual code here.
The problem again is that in the index function only FirstRunnable executes but not the SecondRunnable
final public class Crawler {
    / create an instance of the ISSThreadPoolExecutor /
    private static ThreadPoolExecutor mythreadpoolexecutor = ThreadPoolExecutor.getInstance();
    / Constructor /
    / Index function /
    public void index( .... ) {
        :::::: code :::::::::
        // Execute this folder in a seperate thread.
        this.issthreadpoolexecutor.execute(new FirstRunnable(alpha, beta, gamma));
    / The Inner Class /
    class FirstRunnable implements Runnable {
        public FirstRunnable(int alpha, int beta, int gamma) {
        public void run() {
                        doSomething();
                        // Some other tasks and ...spawn of another thread.
                        issthreadpoolexecutor.execute(new SecondRunnable(a));
         // The Inner Class that Indexes the Folder
          class SecondRunnable implements Runnable {
                  private int ei;
                  public SecondRunnable ( int abc ) {
                        this.ei = abc;
                  public void run() {
                        doSomething ( ".....") ;
          } // End of SecondRunnable Class.
     } // End of FirstRunnable class.
} // End of Crawler Class.
