  org.openejb.alt.assembler.classic.xml.DomOpenEjbConfigurationFactory

All Implemented Interfaces:

OpenEjbConfigurationFactory

public class DomOpenEjbConfigurationFactory
extends java.lang.Object
implements OpenEjbConfigurationFactory

Factory for creating an instance of the OpenEjbConfiguration using DOM and and XML configuration file

DomOpenEjbConfigurationFactory is the default OpenEjbConfigurationFactory, which creates an OpenEjbConfiguration object based on XML config files located on the local system.

The OpenEjbConfiguration object structure provides the inforamtion about the configuration of OpenEJB and the container system and is used by the org.openejb.alt.assembler.classic.Assembler to build a running unstance of OpenEJB.

Other OpenEjbConfigurationFactory implementations can be created that might populate this object using a different approach. Other usefull implementations might be:

• Populating the OpenEjbConfiguration from values in a RDBMS.
• Populating the OpenEjbConfiguration from values in a Properties file.
• Retrieving the OpenEjbConfiguration from a ODBMS.
• Creating the OpenEjbConfiguration using a JavaBeans enabled editing tool or wizard.

If you are interested in creating alternate an OpenEjbConfigurationFactory to do any of the above techniques or a new approach, email the OpenEJB Developer list with a description of the new OpenEjbConfigurationFactory implementation.
