  Understanding Java messaging and JMS
JMS is clearly the missing piece in the enterprise Java architecture, and Sun has already introduced a number of major service APIs -- JDBC (for database access), JNDI (for naming and directory services), and a Java mail API -- that are required in order to write applications that integrate across the enterprise.
JMS does not require that client code be used for asynchronous message consumption, or that it be capable of handling multiple, concurrent messages.
JMS messages sent by a Session to a Destination must be received in the order in which they were sent, so their implementations must provide for the sequencing of incoming messages.

 Using JMS For Distributed Software Development
JMS is typically implemented as a star topology hubbed to a central server.
Because JMS is usually predicated on having end-points establishing persistent connections, this represents a significant issue in terms of scaling a JMS service.
A JMS client can filter the messages it receives from, say, a topic that it is a subscriber to by specifying a selection expression that uses message property values to select which messages will actually be conveyed to the client.

 The JMS Control Developer's Guide
A JMS client, of which the JMS control is an example, sends messages to a queue or receives messages from a queue.
A JMS client, of which the JMS control is an example, publishes messages to a topic, or subscribes to a topic.
Default is empty, which signifies that the JMS correlation header is to be used.

 Java Message Service - Wikipedia, the free encyclopedia
JMS is a specification developed under the Java Community Process as JSR 914.
The same Java classes can be used to communicate with different JMS providers by using the JNDI information for the desired provider.
JMS clients access the connection factory through portable interfaces so the code does not need to be changed if the underlying implementation changes.

 PreciseJava.com - Best practices to improve performance in JMS
JMS clients communicate with each other using messages, this communication occurs in an asynchronous manner, that is when a sender sends a message then it does not wait for the response but continues its flow of execution.
Similarly a JMS connection is also a TCP/IP connection to the JMS server, you need to close the Connection using the close() method as and when you finish your work,so that when you close the Connection it closes it's Session and Producer/Consumer objects also.
Choosing the right JMS server for best performance might be a difficult task since every vendor claims that their server is the best server.

 FAQs: JMS
Note that if JMS boots without a store configured, it is assumed the customer did not want one, and persistent messages are silently downgraded to non-persistent (as specified for JMS 1.0.2b).
WebLogic JMS also has a flow control feature that enables a JMS server or destination to slow down message producers when it is becoming overloaded.
The rules for multi-threading are described in section 2.8 of the JMS specification, with additional language in sections 4.4.6 on session usage, 4.4.9 on using multiple sessions, and 4.4.17 on concurrent message delivery.

 JMS 1.1 simplifies messaging with unified domains
JMS forms the foundation of messaging in enterprise Java applications, but has always treated point-to-point messaging and publish/subscribe messaging as completely separate domains with distinctly different types of messaging destinations.
The JMS 1.0.2 code, shown in Listing 1, required four methods (one pair for queues and another for topics) whereas the JMS 1.1 code only requires two methods (one pair for destinations).
JMS 1.0.2 suffers from an explosion of subtypes; for each type, there is an interface for the type itself, a queue extension, and a topic extension.

 java.net: Loosely Coupled Communication and Coordination in Next-Generation Java Middleware
JMS is always appropriate within systems where the information provider should not be aware of any information consumer.
JMS defines that messages sent by a session to a destination must be received in the order in which they were sent.
JMS messaging provides guaranteed delivery via the once-and-only-once delivery semantics of persistent messages, even if the JMS provider shuts down and has to be restarted.

 WebLogic Server 9.0: JMS Enhancements
JMS resources were created by the WebLogic administrators, prior to any application deployments.
JMS resources can be created as system modules (also known as environment-related) or as application modules. Application modules are managed like standard J2EE modules and can be deployed as standalone modules just like any other J2EE application, or they can be included as part of a J2EE application.
Once the EAR file with the JMS application modules is deployed, it is left to the administrator to define a persistent store for the resources.

JMS operates as a message "pipleline" between two points (point-to-point) or as a publish subscribe system.
Keys to JMS operation are that it runs asynchronously, provides standard message formats, yet is capable of handling persistent transaction quality messages.
JMS uses formats based on XML and is capable of talking with both local and remote databases and business applications.

 ONJava.com -- How to Use JMS with PHP
JMS (Java Messaging Service) is an interface implemented by most J2EE containers in order to provide point-to-point queuing and topic-based (publish/subscribe) functionality.
JMS is frequently used by enterprise and back-end applications for distributed communication and collaboration.
PHPMQ: PHPMQ is an open source serverless messaging toolkit for PHP, giving the PHP developer the ability to perform JMS operations such as sending and receiving messages on queues and topics while ensuring delivery and enabling persistent messaging.

 Implementing vendor-independent JMS solutions
Architecturally, JMS is similar to the Java Database Connectivity (JDBC) API, because they both define a small number of classes but a large collection of interfaces.
This would be ideal because different JMS vendors have different syntaxes for describing hierarchical subscriptions, and by hiding this behind the JNDI-retrieved object, the client would remain ignorant of the underlying JMS implementation.
In such a case, it would be impractical for the JMS administrator to create all the JMS administrative objects necessary to represent all the possible subscriptions.

 JMS Courier for vendor-neutral C++/.NET messaging
JMS Courier leverages Codemesh's in-process integration technology to convey all JMS features to the C++ or.NET developer.
JMS is an enterprise messaging framework, so in all likelihood your C++ or.NET applications have pretty high reliability and performance requirements.
One other implication of the derivation of JMS Courier is that you could use our code generators yourself and add your custom Java types to the set of generated types, thereby publishing your own Java types in the same manner as we published the JMS API.

Some JMS providers will assume that the JMS client is connecting under anonymous security context, while other providers may assume that the credentials can be obtained from JNDI or the current thread.
JMS is an API for asynchronous distributed enterprise messaging that spans processes and machines across a network.
It is also useful where JMS is used purely as a transport between two systems, and the message payload is opaque to the JMS client.

 JMS: A Solution in Search of a Problem?   (Site not responding. Last check: 2007-10-12)
When I've described the Java Message Service (JMS) to developers, I've witnessed ready acceptance to individual JMS interface/object fit and function while at the same time a comprehensive resistance to applying JMS to enterprise systems.
Unless you've used something similar in the past, JMS strikes the pose of an intricate, well-thought-out solution in search of a problem.
On the other hand, a key alternative pattern is RPC (remote procedure calls), which compares with JMS in terms of efficiency.

A consumer endpoint is a server-side http endpoint that will consumer plain JMS, or JMS+SOAP requests and send them into the NMR to a given JBI endpoint, which is called the proxied endpoint.
For example to create an JMS only endpoint and an JMS+SOAP endpoint, both jms endpoints will have the same targetEndpoint and targetService, but they must have different endpoint names.
To retrieve the necessary informations from the wsdl, the component can recognize a jms extension to provide JNDI informations and a jbi extension which specifies the role of the component and the default MEP to use for JBI exchanges.
