I've been using Jboss and Sun's JVM with Seam (nice OSS) and it takes
over a minute to restart the server on a dual processor laptop. I had
to upgrade to 2 gig of memory on the thing otherwise it was constantly
The hot deploy of changed stuff often crashes Jboss and the restart -
debug - hot deploy - crash development cycle makes writing code painful.
So I spend many minutes a day watching scrolling log4j log lines of
various J2EE libraries initialising rather than coding as I would with
Perl. Then when the thing has finally restarted on the first page hit
there's another long wait before the web page finally displays.
I imagine anyone clicking through the pages would then occasionally hit
a freeze while the whole thing garbage collects too.
Not fashionable with J2EE people but I bet for a lot of simple tasks
forked GCJ CGIs would be faster than their stuff ;-) I bet there's
millions of lines of J2EE which doesn't do very much and does it very
Having said all that I like some of the java apps on my mobile and
Eclipse would be nice if emacs didn't already exist...
