Jboss performance Tunining

Hi all,
I am new to this jboss world and have installed in the one of my server for application developers. Now they are complaining that I haven't tuned it for production environment & jboss server is taking huge RAM. What I did was just download the file 4.2.2.GA and untar it to a location to which I gave necessary rights to developers. How they are viewing that memory usage; is there any good monitoring tool?

Now as a system owner what Tuning can be done for making jboss run in production environment? Isn't it secured just out of the box.

Thanks in advance.
FYI, we are running two versions of java as below and System has 4GB RAM.

.../jdk1.5.0_09/bin/java -Xms1m -Xmx30m -classpath

../jdk1.6.0_06/bin/java -Djava.net.preferIPv4Stack=true -Xms10m -Xmx500m

Are you sure that the first line is for JBossAS? I don't think that it will run in 30M of memory.

The second one uses up to 500MB of heap space (actual memory usage is somewhat higher because the JVM also needs some memory to do its work.

What memory usage are they seeing? If it is 700MB, I would not be concerned. If it is 3GB, then there is a problem.

Regarding tuning, see http://wiki.jboss.org/wiki/JBossASTuningSliming, and the Performance Tuning forum also contains many suggestions.

And no, it is not secure right out of the box. See http://wiki.jboss.org/wiki/SecureJBoss
