*
* An adapter for JDBC drivers that do not include an implementation of {@link javax.sql.ConnectionPoolDataSource}, but
* still include a {@link java.sql.DriverManager} implementation. ConnectionPoolDataSources are not used
* within general applications. They are used by DataSource implementations that pool
* Connections, such as {@link org.apache.commons.dbcp2.datasources.SharedPoolDataSource}. A J2EE container
* will normally provide some method of initializing the ConnectionPoolDataSource whose attributes are
* presented as bean getters/setters and then deploying it via JNDI. It is then available as a source of physical
* connections to the database, when the pooling DataSource needs to create a new physical connection.
*
*
* Although normally used within a JNDI environment, the DriverAdapterCPDS can be instantiated and initialized as any
* bean and then attached directly to a pooling DataSource. Jdbc2PoolDataSource can use the
* ConnectionPoolDataSource with or without the use of JNDI.
*
*
* The DriverAdapterCPDS also provides PreparedStatement pooling which is not generally available in jdbc2
* ConnectionPoolDataSource implementation, but is addressed within the jdbc3 specification. The
* PreparedStatement pool in DriverAdapterCPDS has been in the dbcp package for some time, but it has not
* undergone extensive testing in the configuration used here. It should be considered experimental and can be toggled
* with the poolPreparedStatements attribute.
*
*
* The package documentation contains an example using catalina and JNDI. The
* datasources package documentation shows how to use
* DriverAdapterCPDS as a source for Jdbc2PoolDataSource without the use of JNDI.

* usage with commons-beanutils; do not make direct use of it outside of commons-dbcp2.
*
*
*
* A J2EE container will normally provide some method of initializing the DataSource whose attributes are
* presented as bean getters/setters and then deploying it via JNDI. It is then available to an application as a source
* of pooled logical connections to the database. The pool needs a source of physical connections. This source is in the
* form of a ConnectionPoolDataSource that can be specified via the {@link #setDataSourceName(String)} used
* to lookup the source via JNDI.
*
*
*
* Although normally used within a JNDI environment, A DataSource can be instantiated and initialized as any bean. In
* this case the ConnectionPoolDataSource will likely be instantiated in a similar manner. This class
* allows the physical source of connections to be attached directly to this pool using the
* {@link #setConnectionPoolDataSource(ConnectionPoolDataSource)} method.
*
*
*
* The dbcp package contains an adapter, {@link org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS}, that can be
* used to allow the use of DataSource's based on this class with JDBC driver implementations that do not
* supply a ConnectionPoolDataSource, but still provide a {@link java.sql.Driver} implementation.
*
*
*
* The package documentation contains an example using Apache Tomcat and JNDI and it
* also contains a non-JNDI example.
