Hi,

If I understood corectlly you want to access a MBean from a client, yes?
If the client is in the same JVM it is quite easy:
- locate first the MBeanServer using
MBeanServerLocator.locate();
- get a proxy to your MBean using
MBeanProxy.get(...)

If you try to get the MBean from a client outside of the JBOSS JVM you can try it via a RemoteAdapter(ex. RMIAdaptor) or using JBR.

Hi,

Thanks..But I am unable to resolve the errros even after using the RMIAdaptor....I am using :

Properties props= new Properties();
props.put(Context.PROVIDER_URL," jnp://localhost:1099");
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
Context ctx = new InitialContext(props);
RMIAdaptor server = (RMIAdaptor)ctx.lookup("jmx/rmi/RMIAdaptor");
jbMBeanServer = new RMIConnectorImpl(server);

But I am getting the errors as

Error: line (30) cannot resolve symbol class RMIAdaptor

Error: line (31) cannot resolve symbol class RMIConnectorImpl

Error: line (86) cannot resolve symbol class RMIAdaptor

Error: line (86) cannot resolve symbol class RMIAdaptor

Error: line (87) cannot resolve symbol class RMIConnectorImpl


Pls help me out....

Hi,

Just add to your classpath:
jmx-adaptor-plugin.jar or jbossall-client.jar.

Hi,

The MBeanServer that you obtained via RMIAdapter is a Proxy to MBean Server which resides inside of JBOSS server.
You can access the Mbeans using the proxy server methods, or better create you own invocation handler that is able to invoke the remote server.

I did not experience the registring of new MBeans via RMIAdaptor. You can try it ;).
