Annotation Type Lock

  • @Target({TYPE,METHOD})
@Retention(RUNTIME)
public @interface Lock
    Declares a concurrency lock for a singleton session bean with container managed concurrency.

    This annotation may be specified on the bean class, the business methods of the bean class or both. Specifying the annotation on a business method overrides the value specified at class level, if any.

    If this annotation is not used, a value of Lock(WRITE) is assumed.
