/**
* A {@code 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 {@code 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
* {@code javax.jndi.Referenceable} and {@code 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.
