I noticed that Cocoon was slow in JBoss/Jetty as well. I suspect that it 
is simply the VM having to cope with a lot more than just Jetty & JBoss. 
However, if this is the case, then it is a good argument against 
collapsing all your tiers into one process, however you WILL pay on the 
serialisation between your presentation and business tiers. (what VM are 
you using?) Unfortunately, all the work I have done has been on 
colocating these tiers, although it should be possible to seperate them 
and maintain the JAAS functionality - you will need to talk to Scott on 
jboss-user and Greg on jetty-discuss...

Alternatively it could be something about the integration code or Jetty 
that is making it slower. To remove this variable I would try running it 
under standalone Tomcat and JBoss/Tomcat. If Tomcat does not slow down 
then us Jetty guys will have to get our profiling hats on fast....

As for the XML parser problem, I noticed this. I just replaced the 
crimson.jar that comes in JBoss with a xerces jar from the java_xml_pack 
- worked fine. I think that we are just shipping with a slightly ancient 
parser, but didn't follow it up any further... - any takers ?

Let me know if you try the same with Tomcat - I would be very interested 
to hear the results...
