Scott,
Thank you very much for this! A few questions/requests, though:
1) In your document, you state (concerning the WAR Loader):
"The WAR Loader is a servlet container specific ClassLoader that
delegates to the Web ENCLoader as its parent class loader. The default
behavior is to load from its parent class loader and then the war
WEB-INF/{classes,lib} directories. If the servlet 2.3 class loading
model is enabled it will first load from the war WEB-INF/{classes,lib}
and then the parent class loader."
Is the servlet 2.3 class loading model enabled or not by default in
jboss3rc3-tomcat4? What about with Jetty 4? Where is this configured?
2) Under "Disadvantages," you state:
"Deployments that depend on different versions of the a given class need
to be isolated in seperate JBoss servers. This will be addressed in the
RC3 release with an ability to isolate classes using ears."
Since rc3 is out, does the ear isolation method work?
3) Is there any way you can share a bit of info on how jboss 2.4.3+
classloading works? Maybe not to the detail you did for 3.0, but for
those of us stuck with 2.4 at work until 3.0 goes final, it would be
nice to know.
4) Maybe you should send this info to Brett Peterson (guy who wrote
this: http://www.theserverside.com/resources/article.jsp?l=ClassLoading
) so the benefits of JBoss / UCL can be spread.
Thanks again so much!
David
