Hello:
I am going to do the similar thing. Do you know where I can find an example
on the net?
Thanks,

Don't forget to add mutex locking around your connection pool object,
otherwise you will have a race condition and end up with multiple instances
of the connection pool.
> class SingletonConnectionPool {
> private static SingletonConnectionPool m_conPool = null;
private static Object _mutex = new Object(); // JWA
>
> public static getInstance() {
synchronized(_mutex) { // JWA
> if (m_conPool == null)
> m_conPool = new SingletonConnectionPool();
>
} // JWA
> return m_conPool();
> }
>
> private SingletonConnectionPool(...);
> }
