Getting Started with ActiveMQ

1. Download ActiveMQ

and go to the official website to download: http://activemq.apache.org/
2. Run ActiveMQ

to decompress apache-activemq-5.5.1-bin.zip, double-click apache-activemq-5.5.1\bin\activemq .bat runs the ActiveMQ program.

After starting ActiveMQ, log in: http://localhost:8161/admin/, create a Queue and name it FirstQueue.
3. Import the jar package:
