Commons Logging problems
When developing in RAD 7.5, I could not for the life of me get commons-logging to work. After literally hours of digging through source code, I found the problem:
RAD puts its own commons-logging properties file on the classpath. Among other things, this properties file forces the JDK 1.4 logger. If you want to enable any commons logging using log4j, you have to put your own commons-logging.properties file on the classpath.
Once again, IBM has gone out of its way to make my life "easier".
