Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/management/WebLogicMBean

While working in WebLogic, are you haunted by weblogic logging classes (which in 10.3 are spread into a miriad of jar files, and ultimately in any case you can't avoid including weblogic.jar in the classpath, messing around everything else)?

the solution is:
import org.apache.commons.logging.LogFactory;
...


System.setProperty(LogFactory.FACTORY_PROPERTY, "org.apache.commons.logging.impl.Log4jFactory");

This will force Apache Commons Logging to use Log4J rather than WebLogic... and don't listen to people saying that Log4J is the default implementation for Apache... IT IS NOT!

I can't believe in 2010 we are still in such a pathetic shape.... Java will die, it's too messy, everything is just a HUGE mess.... even the fact that in order to log a message I need to instantiate a WebLogicMBean is grotesque. And the fact that the WebLogicMBean initialization fails without a proper error message is grotesque.... EVERYTHING IS GROTESQUE. Why people can't do a proper job. Why do we have to suffer so much.
