Class ConnectionFactoryImpl

java.lang.Object
  org.apache.cocoon.ojb.components.ConnectionFactoryImpl

All Implemented Interfaces:

Disposable, Component, Serviceable, ThreadSafe, org.apache.ojb.broker.accesslayer.ConnectionFactory

public class ConnectionFactoryImpl
extends Object
implements Component, ThreadSafe, Serviceable, Disposable, org.apache.ojb.broker.accesslayer.ConnectionFactory

OJB ConnectionFactory implemenation to bridge into the Avalon DataSource connection pooling component defined in the Cocoon configuration.

This class has two faces to it:

Avalon Component

Instance of the class created and managed by Avalon container. When instance is initialized, it looks up datasource components service selector.

OJB Managed Class

Instances of the class are created and managed by OJB, as defined in the OJB repository.xml file. Each OJB managed instance of the class will have access to the datasource components service selector initialized by Avalon managed instance of the class.

It is important that Avalon component is initialized before any access to OJB API is made.
