That's interesting. Those are all web apps and their
classloaders should have no effect on each other. It's possible that the logging
classes are simply included in a larger bundled JAR file used by JRun making it
harder to locate them. I don't have JRun installed but you could search files
looking for that string and it should be easy to find if they are
there.

The only commons-logging jars came from deploying flex and samples. I
searched from the root of JRun and found four copies in the following
locations:
c:\JRun4\servers\default\flex\WEB-INF\lib
c:\JRun4\servers\default\flex\WEB-INF\flex\jars
c:\JRun4\servers\default\samples\WEB-INF\lib
c:\JRun4\servers\default\samples\WEB-INF\flex\jars
I
removed one of the copies from the samples app to get it to work.
I'm using a fresh install of JRun expressly for deploying Flex, so I
haven't added or modified anything from the default installation.

Either
JRun doesn't normally come bundled with commons logging or they removed it
from the server level classloader in the bundling with FDS. Have you looked to
see where else commons logging is located? It is likely in a directory
called lib or something to that effect on the server level well above the
location of your web applications.

I'm curious to know why FDS with integrated JRun doesn't have this problem
with the samples, yet it has the same jars in the same
place.
Thanks,

Thanks, Carson. I
removed commons-logging.jar from samples/WEB-INF/lib and everything is
working great now. It's also in samples/WEB-INF/flex/jars.

You
have commons logging classes in more than one place which is causing the
classloader to choke. The likely cause of this is a commons logging
jar in the server level classpath. If you don't need it there for
other applications, remove it and restart JRun.

The most detailed instructions I've found for deploying FDS and the
samples on JRun is this:
"For example, for JRun 4 u6, expand the
flex.war, samples.war, and flex-admin.war files to directories named flex,
samples, and flex-admin, respectively. Then copy these directories to the
root of your JRun server instance."
I assume that means
this:
C:\JRun4\servers\default\flex
C:\JRun4\servers\default\flex-admin
C:\JRun4\servers\default\samples
But
there must be something else I have to do for the samples because I can't
deploy them without the following exceptions:
