Quick question - did you had any discussion on class loaders for 
5.next?
It's one area I'm playing with, I want to make sure I'm not going in 
oposite direction :-)

I'll tweak the StandardCL to do a bit the same as the WebappCL (ie, 
try to make it faster). I'll also remove the anti locking hacks which 
are in WebappCL.

Ok. I'm experimenting with having tomcat use other class loaders ( for 
example if embedded in another app, or used with a different runtime - 
like eclipse OSGI  ).

In JBoss, the default is to use the JBoss loader. Is there any big 
difference ?
Both difference and similarity :-).
Eclipse ( osgi actually ) has a similar flat loader implementation, but 
with finer control over what is exported/imported and pretty strong 
versioning. In addition osgi supports permissions on importing packages.
The reloading of modules is a bit more complicated than in jboss ( where 
you just change the jar ).
From tomcat point of view - the implementation should be very similar 
with jboss.

What I like is the standardized and simpler behavior of class loaders, 
with ability to reload and upgrade any module ( like jboss ).


Don't know what "dependency injection" is, but I hope the next spec 
won't invent yet another way to do configuration.

Sorry for using hype words. I got contaminated, it can happen to anyone. 
I'll try to shake it off now. I apologise to the community for that, and 
I won't do it again (hopefully) ;)
Well, when I see a buzz word I don't know I try to search it - and what 
I found on dependency injection is scary ( i.e. avalon and friends ).
