That takes care of part of the problem. Please, I highly recommend stress
testing that setup. Any time you are dependant on the interactions between
two highly complex beasts (JVM and X windows server), there are bound to be
synchronization issues and other bugs that are beyond the control of Cocoon!
Consider the load you are expecting, and test for twice that number. It is
more important that you test for concurrency than for sequential access. If
you expect 100 simultaneous users during peek time, test for 200 users. Use
realistic settings, but test nonetheless.
Keep in mind that any time you incorporate SVG using FOP or Batik, then you
are going to use the X windows server.
If you have _any_ serializers that use Batik (i.e. svg2png, svg2jpg), you are
going to require the use of Batik.
In some instances the setup will be perfectly stable--but some platforms will
prove unstable. It all depends on the implementation of X Windows and the
implementation of the JVM.
When JDK 1.4 becomes stable, the promise of Headless servers will be realized,
and Batik can be used without precaution.
