Subject Re: Web Console (IBM Donation)
Date Tue, 19 Jul 2005 21:23:43 GMT
Regarding #1 below ... I think there are probably some good reasons to 
keep this split into 2 or maybe even more web applications.
As you mention, the "framework" appears to hold the necessary components 
for the console framework itself.  Since this may be replaced
at some point in the future by an open source Portal Server (not just 
the container) it probably makes sense to keep this split apart.
The "standard" application includes the portlets necessary for console 
administration.  One of the benefits of the portlet model (and I
suspect the reason it was chosen for the console) is that it is 
extensible.   Multiple applications can be installed as necessary.  This 
like it would be a desirable feature for a modular server like 
Geronimo.   If there is no need for the EJB container it need not be
included in the resultant image and therefore the portlets that 
administer the EJB container would not be deployed into the solution.
I wasn't one of the authors of this console structure but I can see how 
it makes sense in the big picture even it is seems like overkill for now.

For #2 I think that it is a good idea to provide some level of 
abstraction between the view (console) and the model/controller 
(kernel).  However,
is it really necessary to integrate these changes into the initial 
donation?   This is all internal functionality to the console and the 
kernel functions
are not exposed via any other mechanism beyond this.  Can't we discuss 
what this abstraction should be and then move the console over to
this public interface when it has been created?   I'm not sure why we 
would want to hold up the initial contribution of the console for these
internal changes / new interfaces.
