If you are having trouble creating the aglets, you should make sure you're doing it correctly in the first place.
Make sure you open Thaiti and can create the aglet in there. Then once you have one aglet, that aglet should use it's AgletContext to create a new aglet. Don't use the static creator method. So you would use Tahiti to load "MyAgent", which would immediately spawn another aglet.
public class MyAgent extends Aglet {
     public MyAgent() {
          makeAgent(getAgletContext(),getCodeBase());
     public void makeAgent(AgletContext context, URL codeBase) {
          try {
          context.createAglet(codeBase, "com.agents.BuyerAgent", null);
          catch (Exception e) {
               System.out.println("ERROR: Exception in makeAgent!");
               e.printStackTrace();
}
