Migrating IBM MQ to javax.jms.* implementation - How does MQOPEN translate to JMS API?

由 自闭症网瘾萝莉.ら 提交于 2020-01-25 01:55:45
问题 How do you get the same effect as ibm's proprietary mq api's openOptions when using MQ with JMS api? Is there even a concept of openOptions in the JMS API? If so, what is the equivilent in terms of the API classes/methods? Related stackoverflow question - migrating-from-ibm-mq-to-javax-jms-weblogic 回答1: You are comparing apples and oranges. Yes, both are fruit but they are completely different fruit. There is no direct comparison between the 2. 1) A JMS session with "transacted" and

WSO2 BAM with JMS

由 寵の児 提交于 2020-01-24 20:08:26
问题 The official BAM documentation states that BAM can receive events over Apache Thrift, REST, HTTP and Web services. Strangely JMS is not in the list ? while both CEP & ESB allow JMS transport. I wanted to know is there anyway JMS can be enabled on BAM,we would like to publish our events over JMS and have BAM pick 'em up from the JMS Queue. 回答1: As a workaround, if you are using ESB with your JMS queue, you can use the BAM mediator in the mediator flow to capture data from the JMS message and

How to set Context.INITIAL_CONTEXT_FACTORY? NoInitialContextException?

由 流过昼夜 提交于 2020-01-24 09:44:27
问题 I am new to JMS and the Websphere server and I am trying to access a JMS queue configured on Websphere Application Server 8 from my Java code. I am not able to understand exactly what value should be set for Context.INITIAL_CONTEXT_FACTORY. Should it be the fully qualified class name of the class or something specific to the application server? Hashtable environment = new Hashtable(); environment.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");

Why am I recieving a JMSBytesMessage when I'm sending an OBject message using Spring and MQ Queue

But using Spring's listener implementation I am

Does Google Pub/Sub queue or topic?

由 给你一囗甜甜゛ 提交于 2020-01-24 00:28:07
问题 I am familiar with JMS and novice with Google Pub/Sub. In JMS there are 2 options: Queue : only one consumer can accept message. Topic : each consumer accepts each message from the topic I believe that Google Pub/Sub should support something like this, but a quick Googling didn't help me to answer that question. Please point me out to the corresponding documentation part. 回答1: As the name "Pub/Sub" indicates, Google Pub/Sub supports publish/subscribes semantics which correspond to JMS topics.

Mule session-variable missing from the message, when reading from JMS Queue inside a Component

由 两盒软妹~` 提交于 2020-01-17 06:41:37
问题 I have requirement where in I need to read message from a JMS Queue from inside a Component. But during this process the session variables associated with the message are missing. But the session variables are available when the same message is read from JMS:inbound-endpoint instead of from inside a component. Here are my sample flows. Main flow sets a session-variable into MuleMessage and posts it onto a JMS:outbound-endpoint <flow name="main-flow" > <some inbound> ... < Some processing >

一、什么是消息中间件 　　消息中间件利用高效可靠的消息传递机制进行平台无关的数据交流，并基于数据通信来进行分布式系统的集成。通过提供消息传递和消息排队模型，它可以在分布式环境下扩展进程间的通信。对于消息中间件，常见的角色大致也就有Producer（生产者）、Consumer（消费者） 　　常见的消息中间件产品: （ 1 ） ActiveMQ 　　ActiveMQ 是Apache出品，最流行的，能力强劲的开源消息总线。ActiveMQ 是一个完全支持JMS1.1和J2EE 1.4规范的 JMS Provider实现 ,尽管JMS规范出台已经是很久的事情了,但是JMS在当今的J2EE应用中间仍然扮演着特殊的地位。 　　主要特点： 　　1. 多种语言和协议编写客户端。语言: Java, C, C++, C#, Ruby, Perl, Python, PHP。应用协议: OpenWire,Stomp REST,WS Notification,XMPP,AMQP 　　2. 完全支持JMS1.1和J2EE 1.4规范 (持久化,XA消息,事务) 　　3. 对Spring的支持,ActiveMQ可以很容易内嵌到使用Spring的系统里面去,而且也支持Spring2.0的特性 　　4. 通过了常见J2EE服务器(如 Geronimo,JBoss 4, GlassFish,WebLogic)的测试
