Hello, It looks like something is requiring the Apache Commons Logging component-- though from my quick investigation, I haven't determined what. commons-lang, commons-collections and commons-configuration are all required by the library, but none seem to use commons-logging classes. We don't do any production-level logging in this sample (just System.err.println statements)
One thing to try (if you're just using the sample for learning purposes) would be to copy the commons-logging.jar file into <TOMCAT_HOME>/shared/lib and restarting? This may work-- if not, please let me know and I'll take a look into this further.
