@Deprecated public class ContainerPoolFactory extends Object implements ObjectFactory
Basic JNDI object factory that creates an instance of PoolManager
that has
been configured based on the RefAddr
values of the specified
Reference
.
Here is a sample Tomcat 4.x configuration that sets this class as a default factory for javax.sql.DataSource objects:
<ResourceParams name="jdbc/mydb">
<parameter>
<name>factory</name>
<value>org.apache.cayenne.conn.ContainerPoolFactory</value>
</parameter>
<parameter>
<name>username</name>
<value>andrei</value>
</parameter>
<parameter>
<name>password</name>
<value>bla-bla</value>
</parameter>
<parameter>
<name>driver</name>
<value>org.gjt.mm.mysql.Driver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:mysql://noise/cayenne</value>
</parameter>
<parameter>
<name>min</name>
<value>1</value>
</parameter>
<parameter>
<name>max</name>
<value>3</value>
</parameter>
</ResourceParams>
After ContainerPoolFactory was configured to be used within the container (see above for Tomcat example), you can reference your "jdbc/mydb" DataSource in web application deployment descriptor like that (per Servlet Specification):
<resource-ref>
<es-ref-name>jdbc/mydb</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
