/**
 * 
 * This package contains one public class which is a
 * {@code ConnectionPoolDataSource} (CPDS) implementation that can be used to
 * adapt older {@code Driver} based JDBC implementations. Below is an
 * example of setting up the CPDS to be available via JNDI in the
 * catalina servlet container.
 * 
 * In server.xml, the following would be added to the <Context> for your
 * webapp:
 * 
 *
 *  *  <Resource name="jdbc/bookstoreCPDS" auth="Container"
 *             type="org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS"/>
 *   <ResourceParams name="jdbc/bookstoreCPDS">
 *     <parameter>
 *       <name>factory</name>
 *       <value>org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS</value>
 *     </parameter>
 *         <parameter><name>user</name><value>root</value></parameter>
 *         <parameter><name>password</name><value></value></parameter>
 *         <parameter>
 *             <name>driver</name>
 *             <value>org.gjt.mm.mysql.Driver</value></parameter>
 *         <parameter>
 *              <name>url</name>
 *              <value>jdbc:mysql://localhost:3306/bookstore</value>
 *         </parameter>
 *   </ResourceParams>
 * 
 *
 * 
 * In web.xml.  Note that elements must be given in the order of the dtd
 * described in the servlet specification:
 * 
 *
 *  * <resource-ref>
 *   <description>
 *     Resource reference to a factory for java.sql.Connection
 *     instances that may be used for talking to a particular
 *     database that is configured in the server.xml file.
 *   </description>
 *   <res-ref-name>
 *     jdbc/bookstoreCPDS
 *   </res-ref-name>
 *   <res-type>
 *     org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS
 *   </res-type>
 *   <res-auth>
 *     Container
 *   </res-auth>
 * </resource-ref>
 * 
 *
 * 
 * Catalina deploys all objects configured similarly to above within the
 * java:comp/env namespace.
