[jdev] Using JSO for component development

I'm using JSO to build a component, and I'm finding it more than a  
little confusing.  I've posted to the JSO list, but it's pretty  
quiet, so I thought I'd try my luck here.

Using JSO, I'm able to connect to my server, listen for specific  
packets, and return packets successfully.  The part I don't  
understand is how you continuously listen for packets.  In all the  
example code I've found, the authors have set up an infinite loop  
inside of which they call Stream.process() to process new incoming  
packets, and also keep checking a Queue for new packets to send out.   
This technique works fine, but it seems odd to me, and is quite  
resource intensive on my development machine.  Can someone explain:

1. Why is it done this way?
2. Is there another way to do it?  It seems that I should simply be  
able to call a method that blocks until the packets I need come in  
rather than having to process packets in a tight infinite loop.

I'm also wondering if anyone can recommend any other Java XMPP  
libraries I can use to build an external XMPP component if I can't  
get JSO to work like I want it to.

Thanks,
Christian
