Initializes the update date of this EJB object.

Specified by:

setUpdateDate in interface DbEntity

Returns the identifier of the user having performed the last update on this EJB object.

Specified by:

getUpdateUserId in interface DbEntity

Returns:

a user identifier. Shall not be null.

setUpdateUserId

public abstract void setUpdateUserId(String userId)

Description copied from interface: DbEntity

Specified by:

setUpdateUserId in interface DbEntity

Parameters:

userId - a user identifier. Shall not be null.

getBase

public abstract LocalBase getBase()

Description copied from interface: DbEntity

Returns the base EJB object attached to this EJB object.
Foreign key fields must be nullable by default. This is because the CMP specification requires an insert into the database after the ejbCreate method and an update to it after to pick up CMR changes made in ejbPostCreate. Since the EJB specification does not allow a relationship to be modified until ejbPostCreate, a foreign key will be initially set to null.

Specified by:

getBase in interface DbEntity

Returns:

a base EJB object. Shall not be null.

See Also:

DbEntity.setBase(christophedelory.interfaces.LocalBase)

setBase

public abstract void setBase(LocalBase dbBase)

Description copied from interface: DbEntity

Initializes the associated EJB object.

Specified by:

setBase in interface DbEntity

Parameters:

dbBase - an EJB object. Shall not be null.

See Also:

DbEntity.getBase()

getInstance

public Model getInstance()
                  throws Exception

Returns an instance of this processing model.

Returns:

an instance of this processing model. Shall not be null.

Throws:

EJBException - if any exception occured during the execution of this method.

NamingException - if a naming exception is encountered.

FinderException - in case of failure to find any requested EJB object(s).

Exception - if any exception or error occurs.

ejbCreate

                 throws CreateException

Creates an instance of this entity bean.

Parameters:

className - a fully qualified class name. Shall not be null.

Returns:

null (as EJB 2.0 spec says for CMP ejbCreate() methods).

Throws:

CreateException - the EJB object creation failed.

EJBException - if any exception occured during the execution of this method.

ejbPostCreate

public void ejbPostCreate(String className)
                   throws CreateException,
                          NamingException
