JDeveloper 11.1.1.5 Integrated Weblogic JDKLog4J error

Problem:

After you have changed the logging implementation of your Integrated Weblogic to be Log4J (for whatever good reason), you might see the following exception get thrown on startup: 

<2011/06/03 16:10:35> <Error> <Log Management> <BEA-170022> <Log4j failed to initialize for DefaultServer. The default JDK Logging implementation will be used.
java.lang.ClassNotFoundException: weblogic.logging.log4j.JDKLog4jAdapterFactory

 Solution:

Put the following JARs in your DefaultDomain's lib folder:                                    (<user_home>/JDeveloper/system11.1.1.5.37.60.13/DefaultDomain/lib)  

wllog4j.jar [fetch it from Weblogic's server/lib/ directory]

com.bea.core.apache.log4j_1.2.13.jar [fetch it from JDEV's Middleware/modules/ directory]

Now the Log4J instance of the Integrated Weblogic initialize properly.
