Subject Re: adding a virtual host with jmx
Date Tue, 02 Sep 2008 08:25:05 GMT
yeah i've followed it, but i'm just lost with the first lines:

* ObjectName loader = getServerLoader(); // depends on the settings and*
* version
   ObjectName registry = getRegistry(); // depends on the settings and
version
   MBeanServer server = getTCMBeansServer(); // generally the first one,
unless you (or your J2EE) are playing games
*

For now; I get a MBeanServerConnection and I can invoke the differents
methods like this:

  JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://" +
hostIPAddress + "/jmxrmi");
  JMXConnector   conn = JMXConnectorFactory.connect(url);
   MBeanServerConnection    mbsc = conn.getMBeanServerConnection();


            ObjectName objectName = new
ObjectName("Catalina:type=MBeanFactory");
            Object[] params =
{"Catalina:type=Host,host="+nameVH,"/manager","/data/tomcat/server/manager"};
            String[] signature = {String.class.getName(),
String.class.getName(), String.class.getName()};

             mbsc.invoke(objectName, "createStandardContext", params,
signature);

That's how i create a context for a given host. But like the there is no
addSSOAgentValve, that's why i'm trying to use bill's code .

O.V
