public class MetaObjectManager

extends oracle.jbo.mom.DefinitionManager

A static class used for accessing meta-objects.

This class contains references to all Business Componenents for Java meta-objects. These classes are loaded from XML through JNDI calls to the appropriate context, and are also loaded at runtime from jboserver.properties.

Since:

Jdeveloper 3.0
