JMX registration

Hello,

I have created a MBean that is shipped with my servlet. The MBean is registered (here User) in the init method of the servlet.
I the problem is that I need to hardcode the registration parameters:

public void init() throws ServletException {
try {
MBeanHome home = null;
RemoteMBeanServer rmbs = null;

//domain variables
String url = "t3://localhost:7001";
String serverName = "Server1";
String username = "weblogic";
String password = "weblogic";

//Using MBeanHome to get MBeanServer.
try {
Environment env = new Environment();
env.setProviderUrl(url);
env.setSecurityPrincipal(username);
env.setSecurityCredentials(password);
Context myCtx = env.getInitialContext();
MBeanHome mbeanHome = (MBeanHome) myCtx.lookup(
"weblogic.management.home.localhome");
MBeanServer server = mbeanHome.getMBeanServer();
ObjectName objName = new ObjectName(mbeanHome.getDomainName() +
":Name=MyHello,Type=HelloServlet");
User user = new User();
if (!server.isRegistered(objName)) {
server.registerMBean(user, objName);
}
} catch (Exception e) {
System.out.println("Caught exception: " + e);
}
}

I find this registration a bit annoying and a bit heavy since the registration parameters are shipped within the servlet (whether hardcoded or configured).

I would rather like that the MBean register on the WLS the servlet is deployed whatever the WLS.

Can someone help me with this issue?

Florian.
 
It is sorta covered in the JavaRanch Style Guide.
