Examples of com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource

com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
This class is used to obtain a physical connection and instantiate and return a MysqlPooledConnection. J2EE application servers map client calls to dataSource.getConnection to this class based upon mapping set within deployment descriptor. This class extends MysqlDataSource. @see javax.sql.PooledConnection @see javax.sql.ConnectionPoolDataSource @see org.gjt.mm.mysql.MysqlDataSource @author Todd Wolff
