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

[Tom Bray]

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\libc:\JRun4\servers\default\flex\WEB-INF\flex\jars
c:\JRun4\servers\default\samples\WEB-INF\libc:\JRun4\servers\default\samples\WEB-INF\flex\jarsI 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,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.

    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\flexC:\JRun4\servers\default\flex-adminC:\JRun4\servers\default\samplesBut 
    there must be something else I have to do for the samples because I can't 
    deploy them without the following exceptions: 07/06 10:13:43 error
