Used port not showing up in netstat -a result

问题 This issues started recently when I am trying to start active-mq (which by default starts on port 61616). But suddenly it stopped coming up with JVM_BIND issue on that port. The problem did not go away even after restarting the computer. Main problem is that netstat -a command on Windows 7, does not show that 61616 is consumed. But when I wrote a simple Java program to bind a socket to that port, I wasn't certainly able to! I eventually started active-mq by moving to a different port. But,

常见的消息中间件产品: 【1】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 J2EE1.4 规范的 JMS Provider 实现,我们下面主要说明 ActiveMQ 的实现。 【2】RabbitMQ:AMQP 协议的领导实现,支持多种场景。淘宝的 MySQL 集群内部有使用它进行通讯。OpenStack 开源云平台的通信组件,最先在金融行业得到运用。 【3】ZeroMQ:史上最快的消息队列系统。 【4】Kafka:Apache 下的一个子项目,特点:高吞吐,在一台普通的服务器上既可以达到 10w/s 的吞吐速率,完全的分布式系统,适合处理海量数据。 一、什么是JMS? JMS(Java Message Service)是Java 平台上有关面向消息中间件的技术规范,它使消息系统中的 Java 应用程序进行消息交流,并且通过提供标准的产生、发送、接受消息的接口简化企业应用的开发。JMS 本身只定义了一系列的接口规范,是一种与厂商无关的 API。用来访问消息收发系统。它类似于 JDBC (java DataBase Connecivity),JDBC 是可以访问许多不同关系数据库的 API ,而 JMS 则提供同样与厂商无关的访问方法,以访问消息收发服务。目前许多厂商都支持 JMS,包括 IBM 的

Running ActiveMQ 5.4.0. I have a group of users that subscribe and publish to each other on various topics through a common ActiveMQ JMS provider.

This message occurs repeatedly for various topics. I know that in some cases, some messages are never delivered. None of the producers on the 'net' are implementing any kind of flow control. They just send and forget. Obviously, some of the producers are being blocked, but most

How to Produce from MQTT and consume as MQTT and JMS in ActiveMQ

最后都变了- 提交于 2019-12-05 20:00:54
I have a setup where messages are produced as MQTT to ActiveMQ. I have two consumers one as JMS and another MQTT. When I am publishing message as JMS Message to the topic "foo", I am receiving the messages at both JMS and MQTT consumers, but when I am publishing as MQTT on the same topic I receive the message only on MQTT consumer and nothing at all is received at JMS consumer. Is there something I need to do specifically when publishing as MQTT to be able to consume as MQTT as well as JMS. Please help.
