This sounds like a JBoss classloader isolation problem. commons-codec
is bundled with JBoss (check ${jboss.home}/server/default/lib) and is
made visible to all deployed applications. The JBoss bundled
commons-codec is probably getting loaded instead of the copy found in
your war/ear.
You can modify the classloader isolation settings for applications by
modifying the JBoss deployment descriptors.
http://community.jboss.org/wiki/classloadingconfiguration contains
some good instructions on how this is accomplished.
