not sure what you mean here.

it is very interesting that you say this, because the problem that
I am trying to work around is about singletones.
I have one holy singleton that I would like to see alive
throughtout the life of my web application, but it gets

PS: here is the code in case someone wonders
public class ObjectsManager {
private static Object lock = new Object();
private static Wurfl wurflInstance = null;
private static CapabilityMatrix capabilityMatrixInstance = null;
private static UAManager UAManagerInstance = null;
private static ListManager ListManagerInstance = null;
public static Wurfl getWurflInstance(String parameter, String patch) {
synchronized (lock) {
if (wurflInstance==null)
wurflInstance = new Wurfl (parameter,patch);
return wurflInstance;
}
}

}
