If you do that then its very hard to make the transactional stuff optional or on-demand. Your way requires everything to be installed at the start which isn't what we want further down the road for jboss5. Things should only be created if they are actually needed/used. e.g. No outbound connection factories means no CCM means no listeners on user transactions. There should be no dummy/mock anything. All if you to do is write: if (blah != null) like any normal programmer does around optional/configurable behaviour.

[Design of JBoss Profiler] - Re: Coding standards and process queries

by jesper.pedersen

The folder paradigm won't work in all of our cases - since we have some menu items to connect to agents. The integration with the Embedded Jopr is in the future - we need something that works first ;) As stated previously I would rather have something that just dumps the output (like the command line client) inside < pre > tags and make it pretty / usable later on. As to Beta4 - we will see; it depends on how much time I have in the coming months for this work. Maybe the release criteria is a working web console ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4193464#4193464 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4193464

So configuration error. The empty check is there because otherwise you create an empty iterator for no purpose. Its always been the case that you might not configure any listeners. Look at the old code which is still there. All I've done is moved the registration to one place instead of the listener (the CCM) having to know about all implementations. In particular I want to make jca and jta optional in the web-profile so you can't assume these things will be configured. Or they may get configured "on-demand" later.

Yup, the injection of UserTransaction is a bug. It should always happen by lookup into JNDI.

[Design of JBoss Profiler] - Re: Coding standards and process queries

by rhills

OK, that looks cool, though I don't yet have a good enough feel for the profiler app to be able to say if the folder paradigm would work. My gut feel is that it works better for JBoss-AS configuration than it would for the profiler which seems to have only 2-3 menu levels anyway. That said, maybe the grand plan is to have it somehow plug into an overall JBoss-AS manager app one day. What's your target for the Beta 4 release? I'm wondering if we should tidy up around the edges and release something that basically works (which it didn't before) before going ahead and hacking it to pieces? It's nearly midnight here so I'd better get some shuteye. I'll look for your reply in the morning and then push on with whatever you suggest.

[Design of JBoss Profiler] - Re: Coding standards and process queries

by jesper.pedersen

Well, I havn't looked into the actual usability of the web UI yet. - so you are properly right ;) I think a good idea would be to have a UI similar to Embedded Jopr - see http://www.jboss.org/embjopr/ with the left side being the menu. Feel free to move things around as you see fit.
