public interface Destination
Destinationobject encapsulates a provider-specific address. The Jakarta Messaging API does not define a standard address syntax. Although a standard address syntax was considered, it was decided that the differences in address semantics between existing message-oriented middleware (MOM) products were too wide to bridge with a single syntax.
Destination is an administered object, it may contain provider-specific configuration information in
addition to its address.
The Jakarta Messaging API also supports a client's use of provider-specific address names.
Destination objects support concurrent use.
Destination object is a Jakarta Messaging administered object.
Jakarta Messaging administered objects are objects containing configuration information that are created by an administrator and later used by Jakarta Messaging clients. They make it practical to administer the Jakarta Messaging API in the enterprise.
Although the interfaces for administered objects do not explicitly depend on the Java Naming and Directory Interface (JNDI) API, the Jakarta Messaging API establishes the convention that Jakarta Messaging clients find administered objects by looking them up in a JNDI namespace.
An administrator can place an administered object anywhere in a namespace. The Jakarta Messaging API does not define a naming policy.
It is expected that Jakarta Messaging providers will provide the tools an administrator needs to create and configure administered
objects in a JNDI namespace. Jakarta Messaging provider implementations of administered objects should implement the
java.io.Serializable interfaces so that they can be stored in all JNDI
naming contexts. In addition, it is recommended that these implementations follow the
JavaBeansTM design patterns.
This strategy provides several benefits:
An administered object should not hold on to any remote resources. Its lookup should not use remote resources other than those used by the JNDI API itself.
Clients should think of administered objects as local Java objects. Looking them up should not have any hidden side effects or use surprising amounts of local resources.
