Subject RE: [newbie] JMX Console - where to start?
Date Tue, 02 Sep 2003 03:18:33 GMT
Hey guys,
	Calling the API for the configuration of the server a piece of
middleware is misleading; perhaps it's just inviting potential confusion for
a simple idea? The app. server is the middleware; the console is for
allowing its configuration, through an API.

r.e. a Swing/SWT client:
	Both ATG and BEA have GUI clients for the server, usually for
proprietary orientated configuration and development; portals, workflows,
scenarios, etc.. It's not a bad idea, but I'd opt for the simplest approach;
have it working through a browser as most J2EE developers are used to. Then,
add on other options, like a SWT alternative, as you want them.

	I haven't used JMX yet (which is partly why I want to participate in
Open Source). I do know that it's meant for this sort of thing; we shouldn't
make an exception to the rule.


P.S. This is just my two cents worth. :)

	That "middleware" was the gist of the question I added in the Q&A
section.  My hope would be that the JMX interface is clear enough that the
middleware layer wouldn't really add much.  But without an example to work
with, it's hard to know.  I'd say if the JMX interface is painful to work
with, we should implement the middleware, but if it turns out to be
strightforward, we should skip the middleware.  Again, my hope is that it
should be pretty straightforward.
