Using Catalina API

[Charl Gerber <ch...@yahoo.com>]

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

Hi Charl,

Dunno about a method call that you'd be able to make, but this may get
you half way there:

http://localhost:8080/manager/list

Straight text response, easy to parse. Now, the catch is, you'll need
to be authenticated on the server. Ant has some tools that you may be
able to make use of:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/manager-howto.html#Executing%20Manager%20Commands%20With%20Ant

Cheers,
PST

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);
