Slimming AS 5

Welcome Francesco Marchioni! I've been using JBoss AS 5 for about a year now, and I've been trying to find a slimming guide (something more than my own trial and error). Slimming to reduce the memory footprint and also decrease the boot time (I hear AS 6 M2 is much faster now, haven't look though). I also want to slim because I'm not using some services (such as EJB2). Briefly looking through the TOC for the book it doesn't look like this is covered. Did I miss it, or is there reference somewhere you could point me to?

Hi Jason,
in the second chapter it is showed a "map" of the application services (each service and the corresponding libs/xml file used). Next there's an example of how you can create a custom server configuration by adding/removing services.
You can find info on the JBoss site as well

Very nice, thanks! The last time I looked this document wasn't there, so it must have been created over the past few months. Thanks again!

This "problem" is also partially addressed by the new J2EE 6.0 modularity and profiles.

Very true. Although we don't have an officially production-ready stamped Java EE 6 container from JBoss just yet (There's M1, and M2 -- which I don't think has been released just yet) but I don't think they're quite up to production quality just yet (please correct me if I'm wrong).

So for production deployment (based on my above assumptions) we have AS 5 if you want to stay with JBoss (or GlassFish v3 which looks very compelling I might add). So you'll end up doing some slimming and tuning to stick with AS 5.

Francesco,
Does it mean that JBoss is adopting OSGi?

JBoss has always had different profiles, but Java EE 6 standardized profiles for servers. The first one is the Web Profile.
