Hello,
I am back from holiday; A quick scan of the mailing lists tells me
that the upgrade to WADI 2.0 is causing classloader clashes.
As identified by Jason W. and Kevan, a Tribes class is loaded by two
distinct classloaders (tomcat6 and wadi-clustering configuration
classloaders), which causes CCE upon message delivery. After having
investigated this problem, it seems to me that the best way to fix it
is to split the tomcat6 dependencies into two configurations: tomcat6
and tomcat6-tribes. tomcat6-tribes imports the tomcat6 configuration
and the tribes dependency. The new tomcat6 configuration is the
current tomcat6 configuration minus the tribes dependency. Such a
change will break all the configurations defining Tribes clustering
GBeans. Users having such configurations will have to redeploy them
after having added the tromcat6-tribes configuration.
I tried a backward compatible approach where the tribes dependency
was pushed up to a parent configuration. Unfortunately, this change
can only work if WADI dependencies are also imported by this new
configuration, which is a less ideal approach than the above one.
If no one objects, I intend to check-in this change over the week-end.
Thanks,
Gianny
