Dear list


I have recently been running Tomcat 5 on my server, without problems.
After an upgrade to Tomcat 6, however I get errors. During the upgrade I
manually removed all the Tomcat 5 packages, and dependent packages
before I installed new Tomcat 6 packages from the repo. The
system is a Centos 5 system. This is the error messages:


>From /var/log/tomcat6/catalina.out when running "service tomcat6 start":


WARNING: error instantiating 'org.apache.juli.ClassLoaderLogManager'
referenced by java.util.logging.manager, class not found

java.lang.ClassNotFoundException: org.apache.juli.ClassLoaderLogManager
not found

   <<No stacktrace available>>

WARNING: error instantiating ','
referenced by handlers, class not found


   <<No stacktrace available>>

Exception during runtime initialization


   <<No stacktrace available>>

Caused by: java.lang.NullPointerException

   <<No stacktrace available>>


Then Tomcat dies. 


Running tomcat6-digest with root user gives:


SEVERE: Exception creating instance of

java.lang.ClassNotFoundException: org.apache.catalina.realm.RealmBase
not found in org.apache.catalina.loader.StandardClassLoader{urls=[],
parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}}


   at java.lang.ClassLoader.loadClass(

   at java.lang.ClassLoader.loadClass(

   at org.apache.catalina.startup.Tool.main(


Can someone give me a hint about how to proceed here?
