You can do it that way or do it the JSR-77 way.
Properties props = new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
props.setProperty(Context.PROVIDER_URL, "ejbd://localhost:4201");
props.setProperty(Context.SECURITY_PRINCIPAL, username);
props.setProperty(Context.SECURITY_CREDENTIALS, password);
props.setProperty("openejb.authentication.realmName",
"geronimo-admin");
InitialContext ctx = new InitialContext(p);
ManagementHome mejbHome =
(ManagementHome)ctx.lookup("ejb/mgmt/MEJBRemoteHome");
mejb = mejbHome.create();
Stats stats = (Stats)mejb.getAttribute(new
ObjectName(<mbean_name_here>), "stats");
Hope this helps,
