to solve this problem in order to ensure the message transmission efficiency and message security.If it is a small-scale system, the performance requirements are not high, can be based on server time, using queued queue can be resolved.If the sending end time is the same, and the sequence of messages is sent by this sender, the message sequence number can be used to resolve it.In addition, some systems only need to meet the local message order, in the case of a small number of sorting messages,

(7) ejb3.0 EJB message-driven bean JMS Development 　　I. Java Message Service) 　　 　　Ii. Messages in JMS The center of the message passing system is the message. A Message consists of three parts:Header, property, and body ).Messages are of the following types, all of which are derived from the message interface.Streammessage: a message that contains a Java primitive Value Stream. The filling and reading operations are performed in order.Mapmessage: a message that contains a group of name-value pa

explain in detail the classes in table 1 (such as jmstemplate, destinationresolver, and messageconverter ). # P # Jmstemplate Jmstemplate provides several helper methods to perform basic operations. Before using jmstemplate, it is necessary to know which JMS rules the JMS Provider supportsFan. JBoss as 4.0.2 and WebLogic 8.1 servers support the jms1.0.2 specification. WebLogic Server9.0 supports jms1.1. Jms1.1 unifies the PTP and pub/sub programming

. 　　 JMS Interface Description JMS supports two message types: PTP and pub/sub, called PTP domain and pub/sub domain. Both of these interfaces inherit the unified JMS parent interface, the main interfaces of JMS are as follows: JMS parent Ptpdomain Pub/sub domain Connectionfactory Queueconnectionfactory Topicconnectionfactory Connection Queueconnection Topicc

The file extension is "WAV" and the data format is PCM or compressed.10. Image Transmission ProtocolPicture transfer protocol is short for PTP. PTP is a standard developed by Kodak and Microsoft through negoti

, that is, changing it to pchar still won't work. It should be a problem with this code, because it was good before this code was added, and there was a problem when it was added, after running, the execution result is yes, but a memory error is reported. During the second operation, even if I couldn't even run it, I directly encountered an error. 1. Do not use sharemem if there is no string return value. (sharemem sometimes has problems and I have encountered it too)2. Change string to string

[Message Queue] For platform-independent data exchange. It is a persistent asynchronous communication system, it also integrates distributed systems based on data communication. By providing message transmission and Message Queuing Models, it can expand inter-process communication in a distributed environment and support multi-communication protocols, languages, applications, hardware, and software platforms. Currently, popular mom middleware Products include IBM MQSeries, Bea messageq, and Apa

Messages are of the following types, all of which are derived from the message interface.Streammessage: a message that contains the Java basic value stream. The filling and reading operations are performed in order.Mapmessage: a message that contains a group of name-value pairs. (No entry order defined)Textmessage: a message whose body contains a Java string (for example, an XML message)Objectmessage: a message that contains

architecture. the figure shows the main components of Weblogic JMS server: Weblogic JMS servers (for message communication), Java client, JNDI (for domain name search), and backup storage (for persistent message storage, based on files or JDBC databases ). Ii. WebLogic JMS features1. Message Communication ModelJMS supports two message communication models: point-to-point (PTP) model and pub/Sub Model. Except for the following differences, these two

Regardless of which JMS component is used, JMS supports two distinct messaging models: PTP ( the point-to-point model) and Pub/sub (the publish/Subscribe model), respectively: PTP Domain and Pub/sub domain.PTP (using queue as the queuing target)Messages are routed from one producer to one consumer. In this delivery model, the target is a queue. The message is first routed to the queue target, and then, base
