Creation of url connection pool in java

Question

I have some code like this in a method :

        URL url = new URL(endPoint);
        String encoding = Base64.encodeBase64String(this.key.getBytes());

        connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("POST");
        connection.setDoOutput(true);
        connection.setRequestProperty  ("Authorization", "Basic " + encoding);

This method is called many times from the client side. I wish I could create a connection pool and reuse the same as needed.

Is it possible to do so in Java?

Thanks in advance

Pooling HTTP connection is similar to other pooling object.

Basically :

use a factory to get an instance of your HTTP connections
dont forget to release it, via the factory, to your pool when no more used
in your pool management don't forget to check and close your connections.

I don't advise you to re-code all pool management, but rather use existing librairies like Jakarta Commons-pool.

Jakarta Commons-pool enable you :

to reject immediatly demand of new HTTP connection with a "pool exhausted exception"
to increase pool size despite his limits
to wait during N ms, expecting a free HTTP connection (exception after delay).

thanks.. are there any code examples for Jakarta Commons-pool to pool the url connections? — sriram, Dec 08 '12 at 08:26
