Aaron,
You might be right, there might be examples which we can't find.
>* Establish a container [Merlin and/or Fortress] in a simple main > method and get some simple output form a service
I think Merlin CLI already does that. But the guts of CLI are not typically exposed to a beginner. So if we have an example which just has the simple CLI functionality of loading Merlin Kernel, without all the other code for handling various command line arguments, it would make understanding the Avalon embedding far simpler to beginners. And I think we should keep Merlin and Fortress separate here, cause you understand the nuances, but mixing these would make things harder for beginners. If a separate example for Fortress could be presented also, then more power to you.
>* A simple Swing application in which some frame class accesses > components via an embedded container
Exactly. It doesn't necessarily has to be a swing class, but again more power to you. Basically any class which is not a component but has a starting point like a main method access the methods of the components loaded within the embedded Merlin Kernel
* A simple webapp which starts up a container and then has a second
servlet access services via the container Yeah, very right. This would take things to the next level.
I know you use Fortress a lot, but if Merlin is the is the latest and the greatest then such examples preferably should use Merlin only. Or there should be distinction between examples using Merlin and Fortress.
And thanks a lot for your assistance. I think these examples would help beginners a lot.

+1 on this one. I would like to see such an example also.
And I would also like to hear from anybody in the list who has implemented this functionality, but who is not involved in Avalon or Merlin development at Apache.
If there is anyone like that in the list then we can say that Merlin has started to go places now.
And thanks for your good work guys.

Hi Everybody,
The issue of accessing components from non components in still bugging me.

As suggested by Stephen, I looked at the MerlinServlet ( let me warn that I
may not have the very latest version) and it seems that it is supposed to
load up Merlin in a webapp just like CLI does for a command line
application. Now which examples have non components accessing components ?

Could some one give like few lines of code (for a non component class with a
main method not involving JNDI lookups) which could be used to access our
HelloComponent running inside a Merlin Container? I mean if components are
obtained from Kernel in Merlin, then pls point out how ?????
I think this simple class could make lots of things much clearer for others.
I think that this is a very basic issue which everybody who uses Avalon or
Merlin would have to take care of. I couldn't find an example of that in the
Merlin tutorial examples, the last time I looked at those. So if it is there
then pls point out.
Give an example guys, and I would also document it and put in wiki.
Thanks in advance.

I think cocoon has configuration options and/or blocks that allow you to
export over JNDI and a number of other methods. That might be what you want.
