    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;
