Your JAVA_HOME is not set correctly, Set it to the location where your java is installed.
I doubt that is the problem since Tomcat is at least starting.
I am runing 5.5.9 but ClassloaderManager is not used anywhere.
I do have the following in catalina.bat
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
What has been modified from the original install of Tomcat5.5.9? Did somebody fiddle with catalina.bat?
ClassLoaderLogManager lives in the tomcat-juli.jar found in ..\bin of your tomcat home directory. If it is not being found then I suspect you need to set the environment variable CATALINA_HOME.
