Interface ConnectionFactory

All Known Subinterfaces:
QueueConnectionFactory, TopicConnectionFactory, XAQueueConnectionFactory, XATopicConnectionFactory

public interface ConnectionFactory
A ConnectionFactory object encapsulates a set of connection configuration parameters that has been defined by an administrator. A client uses it to create a connection with a Jakarta Messaging provider.

A ConnectionFactory object is a Jakarta Messaging administered object and supports concurrent use.

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 be both javax.jndi.Referenceable and java.io.Serializable 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:

  • It hides provider-specific details from Jakarta Messaging clients.
  • It abstracts administrative information into objects in the Java programming language ("Java objects") that are easily organized and administered from a common management console.
  • Since there will be JNDI providers for all popular naming services, this means that Jakarta Messaging providers can deliver one implementation of administered objects that will run everywhere.

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.
