org.apache.ojb.ejb.odmg.ODMGBaseBeanImpl
All known Subclasses: org.apache.ojb.ejb.odmg.ArticleManagerODMGBean, org.apache.ojb.ejb.odmg.PersonManagerODMGBean, org.apache.ojb.ejb.odmg.RollbackBean,
| ODMGBaseBeanImpl | | abstract public class ODMGBaseBeanImpl extends SessionBeanImpl (Code) | | Base class for using OJB-ODMG api within SessionBeans,
subclass this class to implement your own bean
implementations.
To keep this example as simple as possible, we lookup a static OJB ODMG
implementation instance from an helper class.
But it's recommended to bind an instances of the ODMG main/access classes in JNDI
(at appServer start), open the database and lookup these instances instance via JNDI in
ejbCreate(), instead of lookup a static instance on each bean creation.
To get the
org.odmg.Database or
org.odmg.Implementation instance use
the
ODMGBaseBeanImpl.getDatabase and
ODMGBaseBeanImpl.getImplementation methods.
Additionally there are some basic methods for
storing, deleting, counting, get all objects
implemented.
