The JMS programming model is discussed in this section.JMS defines an API for accessing services from a messaging provider; that is, it is not a product itself. It is a set of interface classes that messaging provider vendors implement. Applications that use the JMS API can then communicate ...
本節將討論 WebSphere® MQ JMS 程式設計模型。 IBM® WebSphere MQ 類別 (也稱為 WebSphere MQ JMS) 是一組 Java 類別,可讓 JMS 應用程式使用 WebSphere MQ 系統作為其傳訊提供者。 同時支援 JMS 的點對點和發佈/訂閱模型。 這些 Java 類別是 IBM WebSphere MQ 用戶端支援的一部分。 JMS 應用程式撰寫...
In addition to looking up a connection factory in a client program, you usually look up a destination. Unlike connection factories, destinations are specific to one domain or the other. To create an application that allows you to use the same code for both topics and queues, you cast and a...
the JMS API provides an object that allows you to browse the messages in the queue and display the header values for each message. To create aQueueBrowserobject, use theSession.createBrowsermethod

Point-to-Point (Queue destination): In this model, a message is delivered from a producer to one consumer. The messages are delivered to the destination, which is a queue, and then delivered to one of the consumers registered for the queue. While any number of producers can send messages ...
Unlike other JMS providers JOMS uses a server-less model: message queues and topics are distributed in the network, and a distributed directory service is used to discover and locate destination objects. Additionally, message dissemination in the network relies on a content-driven epidemic model, ...

本部分中讨论了 JMS 编程模型。 JMS 定义用于从消息传递提供程序访问服务的 API;即它并不是产品本身。它是消息传递提供程序供应商实施的一组接口类。然后,使用 JMS API 的应用程序可以与供应商提供的消息传递提供程序进行通信。JMS API 已成为 Java™ 应用程序的业界标准接口,可使用支持 JMS API 的消息传递提供...
