Great. Thanks :)

Yes, I understand that. I think that I've tried to use invm configuration
provided with the war for this purpose and as I remember it didn't work (but
I have to check it out), so I used the 'embedded' configuration you created
for ActiveMQ itself.

Also, maybe we could ease the configuration if we provide a way to define
configuration type through the web.xml (or dispatcher-servlet.xml). For
example to use <context-param> to specify this. I think it is a better fit
for web applications. Of course, system property would have a priority, so
it would be backward-compatible. What do you think?

I saw that, great work. I think we can create a separate artifact (.zip ??)
of web-console for people that want to use it this way. It will come with
only subset of JARs in the WEB-INF lib folder and proper configuration
files. Then folks who want to embed the console this way would just need to
extract it to their app and configure (no need to filter libs or conf
files). Just an idea, of course :)

Yes, just for the excluding files :) I saw the comment in the
unix-bin.xmlregarding this. It definitely works fine this way, but it
would just be a
bit cleaner.

Of course, I'm willing to help if we agree that any changes should be made
