JAXB Annotations

SOA/IoC

JAX-WS Annotations

IoC annotations direct the assembler to perform injection or other lifecycle events..

@EJB

@PersistenceContext

@PersistenceUnit

@PostConstruct

@PreDestroy

@Resource

@EJB

@EJB requests the injection of an EJB session bean.

@EJB
@Target({TYPE, METHOD, FIELD}) public @interface EJB { String name() default ""; Class beanInterface() default Object.class; String beanName() default ""; String mappedName() default ""; }

@PersistenceContext

@PersistenceContext requests the injection of a JPA PersistenceContext.

@PersistenceContext(unitName="test")
EntityManager _em;

@PersistenceContext


package javax.persistence;

@Target({TYPE, METHOD, FIELD})
public @interface PersistenceUnit {
  String name() default "";
  String unitName() default "";
  PersistenceContextType type() default TRANSACTION;
  PersistenceProperty[] properties() default {};
}

@PersistenceUnit

@PersistenceUnit requests the injection of a JPA PersistenceUnit.

@PersistenceUnit(unitName="test")
EntityManagerFactory _emf;

@PersistenceUnit
package javax.persistence; @Target({TYPE, METHOD, FIELD}) public @interface PersistenceUnit { String name() default ""; String unitName() default ""; }

@PostConstruct

javax.annotation.PostConstruct tells the assembler to call a method after the bean has been built, but before it is active.

@PostConstruct
package javax.annotation; @Target(value={PACKAGE,TYPE}) public @interface PostConstruct { }

@PreDestroy

javax.annotation.PreDestroy tells the container to call the annotated method before it is destroyed.

@PreDestroy
package javax.annotation; @Target(value={PACKAGE,TYPE}) public @interface PreDestroy { }

@Resource

@Resource tells the assembler to retrieve a resource an assign it to a field or property. Typically, the resource will be stored in JNDI.

Known types
DataSource	Configured by <database>
UserTransaction	User XA interface provided by Resin
Executor	JDK 1.5 thread pool interface (see java.util.concurrent)

@Resource


package javax.annotation;

@Target({TYPE, METHOD, FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface Resource {
  String name() default "";

  Class<?> type() default Object.class;
  AuthenticationType authenticationType() default CONTAINER;
  boolean shareable() default true;
  String mappedName() default "";
  String description() default "";
}
