It's a lot of lines of code, but not that hard. You haven't mentioned your
Tomcat version, so I'll give a sort of generic setup.
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
String hname = "Catalina:type=Host,host="+hostName; // Assuming the
default Engine name of "Catalina"
ObjectName ohost = new ObjectName(hname);
Object host = server.instantiate(HOST_CLASS, loader);
server.invoke(registry, "registerComponent",
new Object[] {host, hname, null},
new String[]
{"java.lang.Object","java.lang.String","java.lang.String"});
server.setAttribute(ohost, new Attribute("appBase", appBase));
// Set more attributes, and aliases etc here
// Things like Realms and Contexts work much the same way if you follow
Tomcat's naming conventions
server.invoke(ohost, "start", null, null);
// Start your contexts here, if you don't have automatic deployment set.
As long as you follow Tomcat's naming conventions for ObjectNames, invoking
"start" will automagically add the new elements to where they should live.
You can get the values for the "loader" and "registry" by hooking up a JMX
console to your existing Tomcat.
