We get a list of sessions from a specific webapp by using the JMX interface,
once you get a connection you could get a list of all "manager" mbeans
(webapps) and then invoke the listsessions method on each manager to get a
list of sessions..
However.. This only seems to work with the older 1.1.1 version of MX4J and
for some reason, I can't get anyone to give me a clue as to how to use the
3.0.1 newer version properly, from the tomcat list nor the MX4J list. The
1.1.1 version has the bad side-effect of not always cleaning up its threads
and can hang tomcat on shutdown.
This was used on Tomcat 5.0.28, using the MX4J 1.1.1 libs.
-- conf/jk2.properties --------------------
mx.port=1099
mx.enabled=true
mx.jrmpPort=1099
mx.jrmpHost=localhost
-- Code ------------------------------
Hashtable environment = new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.rmi.registry.RegistryContextFactory");
environment.put(Context.PROVIDER_URL,"rmi://localhost:1099");
JRMPConnector connector = new JMRPConnector();
connector.connect("jrmp", environment);
RemoteMBeanServer server = connector.getRemoteMBeanServer();
ObjectName ob = new ObjectName("mywebapp");
Object[] params = {};
String[] signature = {};
String result =
(String)mServer.invoke(ob,"listSessionIds",params,signature);

How can you determine all the loaded webapps and active sessions across all
webapps using the Catalina (or other Tomcat) API? The Javadoc does not seem
to provide a sort of utility class with static methods to get this info.
Thanks
