This package contains one public class which is a
ConnectionPoolDataSource (CPDS) implementation that can be used to
adapt older 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.dbcp.cpdsadapter.DriverAdapterCPDS"/>
<ResourceParams name="jdbc/bookstoreCPDS">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.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.dbcp.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.
