Setup: Eclipse Juno R, Tomcat 7.0.8, tomcat run through eclipse plug in. Tomcat launch configuration from eclipse has VM argument -Djava.util.logging.confi
Ensure the following system property is set,
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
As seen here on the tomcat users mailing list.
I had the same problem launching tomcat with YAJSW instead of using the tomcat startup scripts.
