@Target(value={TYPE,METHOD,FIELD}) @Retention(value=RUNTIME) public @interface EJB
Either the beanName
or the lookup
element can
be used to resolve the enterprise bean dependency to its target session bean component.
It is an error to specify values for both beanName
and
lookup
.
If no explicit linking information is provided and there is only one session bean within the same application that exposes the matching client view type, by default the enterprise bean dependency resolves to that session bean.

Class |
beanInterface
The interface type of the Enterprise Bean to which this reference
is mapped.
|
String |
beanName
The
beanName element references the value of the name
element of the Stateful or Stateless annotation,
whether defaulted or explicit. |
String |
description
A string describing the bean.
|
String |
lookup
A portable lookup string containing the JNDI name for the target enterprise bean component.
|
String |
mappedName
The product specific name of the enterprise bean component to which this
enterprise bean reference should be mapped.
|

public abstract String beanName
beanName
element references the value of the name
element of the Stateful
or Stateless
annotation,
whether defaulted or explicit. If the deployment descriptor was used to define
the name of the bean, the beanName
element references the
ejb-name
element of the bean definition.
The beanName
element allows disambiguation if multiple session
beans in the ejb-jar implement the same interface.
In order to reference a bean in another ejb-jar file in the same application,
the beanName
may be composed of a path name specifying the ejb-jar
containing the referenced bean with the bean name of the target bean appended and
separated from the path name by #. The path name is relative to the jar file
containing the component that is referencing the target bean.
Only applicable if the target enterprise bean is defined within the same application or stand-alone module as the declaring component.
public abstract Class beanInterface
Holds one of the following types of the target enterprise bean :
public abstract String mappedName
Application servers are not required to support any particular form or type of mapped name, nor the ability to use mapped names. The mapped name is product-dependent and often installation-dependent. No use of a mapped name is portable.
