Subject: Singleton in Tomcat 6.0 not working
Hi,
I am using Tomcat 6.0.16 with JDK 1.6. I created a web application and
deployed it as ROOT. (I removed the default ROOT which comes with tomcat).
The problem I am facing is the Singleton is not working at all in the
servlet. I tried to synchnozed the constructor or make it static. I still
get two instances of the objects. How can I solve the problem?
e.g.
=======
public class RemoteDBConnections
{
private static RemoteDBConnections sInstance = new
RemoteDBConnections();
private static int counter=0;
private RemoteDBConnections()
{
System.out.println("counter =" + (counter++));
};
public static synchronized RemoteDBConnections getInstance()
{
return sInstance;
}
}
======
Thanks in advance
Elwin

Looks good to me... cant see anything wrong
Maybe the call is wrong
Should be
RemoteDBConnections obj = RemoteDBConnections.getInstance();
Doing
RemoteDBConnections obj = new RemoteDBConnections().getInstance();
would make 2 counters
Maybe you just slipped in the call... but even then counter will clock twice
but instance will just be one.
Maybe... guessing ;)
Give Up ;)
