5.0.28 w/ MX4J 3.0.1, possible?
Hello,
I have been trying to migrate to the latest version of MX4J (3.0.1) from
the old 1.1.1 version.
And for the life of me, I don't seem to be able to get it to work. I use
JMX to communicate to various servers in our webapp to show session info on
different nodes, and I would also like to implement some other features..
Old 1.1.1 implementation
-- jk2.properties --------------------
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();
----------------------------------------
Ok.. So I replaced jmx.jar with the latest version of mx4j.jar (renamed to
jmx.jar) under tomcat_home/bin
And replaced or added
Mx4j-jmx.jar
Mx4j-tools.jar
Mx4j-remote.jar
To /tomcat_home/common/lib
Now, when I start tomcat I get the error..
"MX4j RMI adapter not loaded: java.lang.ClassNotFoundException:
mx4j.adaptor.rmi.jrmp.JRMPAdaptor "
Which is correct, since that's not a valid class now, but how do I configure
tomcat to properly use the new mx4j.
If I enable mx.httpPort=9000/mx.httpHost=localhost then JMX does enable and
I get a pretty little message like...
"HttpAdapter version 3.0.1 started on port 9000" , but I have no idea at
this point how to properly use the HTTP connector.
Any info or suggestions to getting the RMI adapter working, or how to use
the http adapter, or just the best way to go about
Using MX4J, not sure if either is possible with out updating to tomcat
5.5.x.
Thanks,
Rick

Repost, hadn't heard anything...
Anyone have a code example of talking to the JMX Http interface
pragmatically? With latest MX4J or JMXRI?
Thanks Bill,
So if I can only use the http method, then I assume I should be able to
make the code work using the newer MX4J HTTPConnector? Or am I missing
something.
Anyone have a code snippet using the HTTPConnector to connect to Tomcat's
Mbean server? I seem to be having trouble getting the url syntax to work
with..
-------------------------------------------
JMXServiceURL address = new JMXServiceURL("http", "localhost", 9000);
-------------------------------------------
I get the error..
-------------------------------------------
java.net.MalformedURLException: Could not find provider for protocol http
-------------------------------------------
So I'm a bit stumped, if I'm using http, why is it saying it has no provider
for it, is there some other I need to use in its place?
Thanks again
-Rick

Yep. The jrmp adapter is gone.

The RMI adapter is gone in mx4j 3.x. There is nothing that Tomat can do
about it. You can access the http adapter by simply typing
http://localhost:9000 in you favorite browser. The only thing you gain by
upgrading to 5.5.x is the ability to use the http adapter in XML instead of
HTML.
