------------------------------------
Hi Randy,
I have been struggling with exactly the same issue for the last few days now.
It seems to be a classloader visibility problem. I have tried literally every
combination like creating shared-libraries for wsif.jar, log4j.jar and
commons-logging.jar, removing inherited shared libraries etc..
sometimes I am getting NoClassDefFound when Trc.entry() is called and sometimes
I get problems with multiple common.logging classes found in classloader
hierachy (which seems to suggest to me that common.logging is loaded at a
higher level in the class loader?)
Im assuming its a problem between wsif.jar and commons-logging.jar and where
they sit in the classloader tree.
could you explain further what you mean by 'turning off classpath inclusion in
the core container'. also are you deploying the common-logging jars with your
app or importing them as shared libraries?
thank you in advance,
Layne
