  Tutorial: Pool resources using Apache's Commons Pool Framework

Resource pooling is not new and is being widely used to conserve and optimize the usage of resources like threads, sockets, and database connections. Web server implementations routinely use thread pool implementations for performance and scalability reas

Tutorial Details:

Pooling resources (also called object pooling) among multiple clients is a technique used to promote object reuse and to reduce the overhead of creating new resources, resulting in better performance and throughput. Imagine a heavy-duty Java server application that sends hundreds of SQL queries by opening and closing connections for every SQL request. Or a Web server that serves hundreds of HTTP requests, handling each request by spawning a separate thread. Or imagine creating an XML parser instance for every request to parse a document without reusing the instances. These are some of the scenarios that warrant optimization of the resources being used.
