ACTIVEMQ instances of simple send and receive messages

First, the Environment preparation

1, official website http://activemq.apache.org/Download the latest version of ACTIVEMQ, and unzip

2, open the corresponding directory, in the MAC environment, you can generally run the command:

cd/users/***/downloads/apache-activemq-***/bin/macosx

./activemq Start

3, after successful startup, log in http://localhose:8161/admin/, login account and password are admin, create a queue named Jyqueue.

Ii. Creating an Eclipse project

1. Create a new project and import the corresponding jar file as shown in

2,sender.java and Receiver.java
