New Object Pooling project

Hi all,

I've released a beta of my Object Pooling software and it's freely available
on my web site:

http://web.bvu.edu/staff/david/pooling/

This is an extensible Object Pooling system that could be extendend to
handle pooling of just about any Object type. The initial release contains a
full database connection pooling system.

The main distinction between this pooling system and the others I can find
is that there's no need to pre-configure the pools or use JNDI.

I'm not sure what you mean by "pre-configure" the pools, but the
pooling library that's part of the Apache Commons project is pretty
simple. Here's a code snippet that creates a pooling
javax.sql.DataSource, and it doesn't require JNDI:

DriverConnectionFactory connFactory
= new DriverConnectionFactory(driver, url, propertiess);

GenericObjectPool genericPool = new GenericObjectPool(null,
maxConnections);
genericPool.setWhenExhaustedAction(genericPool.WHEN_EXHAUSTED_FAIL);
PoolableConnectionFactory
poolableConnectionFactory
= new PoolableConnectionFactory(connFactory,
genericPool,null, null, false, true);
PoolingDataSource dataSource
= new PoolingDataSource(genericPool);
return dataSource;
