java jms queue example

Recently, there is a project to use JMS, and therefore a little learning. A messaging service means that two or more clients can communicate by sending and receiving messages (in a peer-to-peer manner). A message is a "piece" of data sent by a client to another client via a message server, either textual or numeric, and the data can include objects if the client is a Java application. Where the client does

: Non-underlying operating system software, non-business application software, not directly to the end user, not directly to the customer value of the software collectively referred to as middleware. What is message middleware: Focus on sending and receiving data and integrating distributed systems with efficient and reliable asynchronous message delivery mechanisms Message Middleware Flowchart:Speaking of message middleware has to mention the

A profound understanding of JMS (Java Message Service) and jmsmessage JMS has been available for a long time. This is especially true on the Internet, but most of the summary is not comprehensive and not specific. Based on the existing learning resources, I Will resummarize it: JMS is called

(such as dBase or Microsoft Access) to a Working Group database server (for example, Sybase sql/anywhere). Then to the Enterprise database server (for example, DB2 or Oracle). No matter what your project looks like, there's always a database product that's affordable, performance, and functionality that you can use. Like databases, MQ products are sometimes referred to as message-oriented middleware (MOM)

work. During the waiting period, the sender is in a blocking state. In the RPC system, the client and server must be online at the same time, but this requirement is usually difficult to meet. At the same time, mom is based on the Asynchronous interaction mechanism and abstracts a message queue. This message queue allows access over the network. Note that the "message" mentioned here refers to the requests

lost. And MQ is the equivalent of a middleware I send a request must first be communicated to the Message Queuing component, and then by the Message Queuing component to another server to request, have a response and then return to the original requestor, because the MessageQueue component will persist the message on the local, So even if the sudden crash, the request message is not lost. For example, we have a complex request to generate a report, t

be either a producer or a consumer, and a business system consisting of a JMS Provider. JMS enables us to send messages from one application to another through the messaging service (that is, JMS Provider, sometimes referred to as a message broker or a messaging server).The programming process for JMS is simple, and i

RPC: (Remote Procedure Call)A platform-neutral approach designed to communicate between applications, ignoring differences between operating systems and languages. Multi-lingual supportRMI: (Remote Method invocation)The Java version of RPC, the underlying technology of EJBRMI uses JRMP (Java Remote method Protocol) communication protocol, which is a kind of remote calling method built on TCP/IP protocol.RMI
