org.objectstyle.cayenne.conn
Class ContainerPoolFactory

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

All Implemented Interfaces:: javax.naming.spi.ObjectFactory

public class ContainerPoolFactory
extends java.lang.Object
implements javax.naming.spi.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 4.0.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.objectstyle.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>
