Help with simple sample setup.

[thenelson]

I'm running the example from http://wiki.jboss.org/wiki/Wiki.jsp?page=JMXMBeanRemoteProxy
but whenever my clients try to connect they cannot find the object in the JNDI registry.

When I do a "/usr/local/jboss/bin/twiddle.sh --server=10.140.0.190:1099 serverinfo --list" I see the new InvokeTarget listed:

jboss.management.local:ServiceModule=foo.sar,name=jboss.jmx%3atype%3dadaptor%2cname%3dMyServiceInvokeTarget%2cprotocol%3djrmp%2cservice%3dproxyFactory,J2EEServer=Local,J2EEApplication=null,j2eeType=MBean
jboss.jmx:type=adaptor,name=MyServiceInvokeTarget,protocol=jrmp,service=proxyFactory


but when my client code tries to connect to it, it always fails to look it up. Here is the client code:

try {
Hashtable<String,String> environment = new Hashtable<String,String>();
environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
environment.put(Context.PROVIDER_URL, "jnp://10.140.0.190:1099"); // remote machine IP
InitialContext ic = new InitialContext( environment );
MyServiceMBean myService = (MyServiceMBean)ic.lookup("MyService");
} catch( Exception e ) {
log.error("exception: " + e);
}



I'm sure there is something stupid I'm seeing or doing. I'm running on Jboss 4.2 with a fairly stock default like server.

thanks for any suggestions.

what's the exception you're getting?

[thenelson]

javax.naming.NameNotFoundException: MyServiceInvokeTarget not bound

I think I had a typo in the code I posted, as I was hacking around. I tried to look up MyService as well as MyServiceInvokeTarget and both failed the same way.

thanks,

[waynebaylor]

okay, are you deploying a jar or an ear? if you're using a jar, the name is BeanName/local or BeanName/remote; if you're using an ear, then the name is EarName/BeanName/local or EarName/BeanName/remote.

and have you checked JNDIView too see if the name is there?

[thenelson]

I'm trying to deploy it from a sar. Does that now work?

It's not in jndiview anywhere.

[waynebaylor]

sars are okay, but MBeans aren't stored in JNDI automatically like Session beans.

[thenelson]

What do I have to do to fix that?

Is that a configuration thing I could put in jboss-service.xml?


thank you again, I've been banging my head on this..

[waynebaylor]

you can monitor your MBean from the jmx-console, or do you need to use an application client?

[thenelson]

Once I see how to make this work I'm going to remotely monitor mbeans from within my application.

[waynebaylor]

well, i'm not a JMX guru, but i had to add the following to my run.conf to enable remote JMX in jboss:

#added for remote access to JMX (for example Hyperic)
JAVA_OPTS="$JAVA_OPTS -Djavax.management.builder.initial=org.jboss.system.server.jmx.MBeanServerBuilderImpl"
JAVA_OPTS="$JAVA_OPTS -Djboss.platform.mbeanserver"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote"

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.authenticate=false"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.ssl=false"
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=3099"

with that i was able to use jconsole to connect to the JMX server in jboss (there's nothing special about the port, i think)

[thenelson]

Thank you, I'm still not there though.

I'll post this in the JMX forum as well.

[thenelson]

Still not working. I'm asking in the JMX group also.
