Hi Aaron,

sorry for the late answer, I just found your email under my spam
directoy :-) I also cc my answer to OpenUSS and JOnAS community...

Yup. We also use Enhydra Director to load balance
JOnAS installations. Please check this article for more details:

Nope. For the development we use EJOSA structure and process.
For more details please refer to EJOSA documentation:

Nope. In the old days (it was JOnAS 2.4 or so) I had some problems with
memory leak but now with JOnAS 3.1 (yes, we still use JOnAS 3.1 but we
want to update to JOnAS 3.3.6) everything seems to work ok.

Very quick, just ask the JOnAS mailinglist. You normally get tbe answer
very fast...

Hmm... I believe in Open Source community, so, I do think so :-)
I have to admit that I never had any commercial supports or so.
We also don't have any commercial support for our application.

Nothing at all and this is the advantage of *standard*! Since JOnAS is
*only* an implementation of the "J2EE specification", you always can
change the implementation if you are not happy with the current
implementation. One important thing is that you should *never* use the
vendor specific extension of the specification in your application, so
you will never need to change your application in case that you want to
change your application server. Using JOnAs specific optimization - as
long as it does not extend the concept - is ok.

Yes in the old time... ;-) I just asked the mailinglist of JOnAS.
Mostly I always get an answer in short time...

Yes.

Your welcome! Again, go for JOnAS for development and you can use JOnAS
as well for production. Thanks to the standard like J2EE specification
you always can change your application server (commercial) if you want
to:
- Servlet is always servlet
- EJB is always EJB
