How to get embedded these two windows? JXTA login and JXTA shell

Greetings, jxta users!

Does exist any way to get embedded the "JXTA Secure Login" window shown 
during the "Interactive Autenthication"  and the "JXTA Shell" window?

I pretend to get the JFrame or JDialog component from these windows in 
order to manage them in my own GUI Swing-based application (add them in 
other panels, embed them in several InternalFrames from my JDesktop or 
similar...)

I've examined the Shell api without finding the correct class. About the 
Jxta Secure Login, no documentation found on jxta.org, api's, wiki, 
google, similar...

Thanks in advance!

PD: To launch the JXTA shell in my jxta application i use the same steps 
from James Todd's MyJXTA app:

public void launchJxtaShell(PeerGroup peerGroup){
        System.setProperty(Shell.JXTA_SHELL_EMBEDDED_KEY, "true");
        peerGroup.startApp(null);
}
