Re: [flexcoders] when I deploy samples in JRun, I get: org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy

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,

Tom

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.

Subject: [flexcoders] when I deploy samples in JRun, I get: org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy

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:
