Interface EntityPropertyManager

All Known Subinterfaces:

CustomerPropertyManager, LdapPropertyManager

public interface EntityPropertyManager

extends javax.ejb.EJBObject

EntityPropertyManager is the remote interface for a session bean that manages persistence of ConfigurableEntity EJB's and their properties. The default implementation uses the WLPS database as its backing store, other implementations may use other datastores such as an LDAP server.

Each ConfigurableEntity must have an ejb-ref in its deployment descriptor that can be used to identify the correct EntityPropertyManager to use.

Parameters:

locator - a PropertyLocator identifying the entity to look up

propertySet - the propertySet to look up

Returns:

a String array of property names
