Put a direction in the constructor: 
public Bullet(int rotation)
{
    setRotation(rotation);
}
Then when you add the bullet you should use the rotation of the rocket. So in the rocket class you can get it by using getRotation(). So if you add the bullet from the Rocket class you would create a new bullet using the following code: Bullet bullet = new Bullet(getRotation());

Create the bullet as follows: 
Bullet bullet = new Bullet(); // create the bullet
bullet.setRotation(getRotation()); // set its rotation
getWorld().addObject(bullet, getX(), getY()); // add to world at rocket location
bullet.move((getWidth()-bullet.getWidth())/2); // move to front of rocket
