Hello List
i just upgraded my tomcat to 5.5.17 mdk , since we wanted to test the
replication mechanism of the tomcat 5.5 .
after i added the <Cluster> definitions in the server.xml i get the
following error :
3543 [main] ERROR org.apache.catalina.mbeans.ServerLifecycleListener -
Exception handling NamingResources property change
javax.management.MBeanException: Cannot load ModelMBean class

a:1315)
i looked and found that the class reported as missing in available and
readable:
unzip -l /var/lib/tomcat5/server/lib/catalina.jar | grep
ContextEnvironmentMBean
1698 07-19-06 10:42
org/apache/catalina/mbeans/ContextEnvironmentMBean.class
what appears to be the problem is that the
<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />
is calling WebappClassLoader which fails to load and work .
google and archives didn't help me on this so ..
any ideas on how i can make this work ?
Thanks
Assaf
