XDoclet and EJB technology: ejb.pk field

The

ejb.pk field

marks a CMP field as participating as part of a compound key.

You do not need this for this example. But if the

DeptBean

had a complex you would

need it.

/**

* This is a cmp field.

* And it is the primary key.

*

* @ejb:pk field

*/

public abstract Integer getId();

public abstract void setId(Integer id);

XDoclet and EJB technology: ejb.persistent field

The ejb.persistent field tag marks a getter method as being part of a CMP field

declaration. This will cause the corresponding cmp field elements to be generated in

the EJB deployment descriptor:

/**

* This is a cmp field.

* And it is the primary key.

*

* @ejb.persistent field

...

*/

public abstract Integer getId();

public abstract void setId(Integer id);

The above XDoclet tag would cause the following

to be generated.

This entity bean represents a Department of

Employees.
