## org.apache.cayenne.conn
Class ContainerPoolFactory

    java.lang.Object
      org.apache.cayenne.conn.ContainerPoolFactory

All Implemented Interfaces:
  ObjectFactory

Deprecated. since 3.1. This class does not belong in Cayenne, as Cayenne no longer attempts to provide appserver pieces. End users should not need this class and should use their container's preferred approach to map a DataSource instead.

    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>

`
