Choose a message broker

ActiveMQ

Apache ActiveMQ is an open source message broker written in Java together with a full Java Message Service (JMS) client. It provides "Enterprise Features" which in this case means fostering the communication from more than one client or server. Supported clients include Java via JMS 1.1 as well as several other "cross language" clients. The communication is managed with features such as computer clustering and ability to use any database as a JMS persistence provider besides virtual memory, cache, and journal persistency.

Configure message-broker environment

• Download activeMQ
• Add activemq\bin\win64 or activemq\bin\win32 to system path according to your system version, so that you can open activemq by just typing activemq into shell no matter which path it is now.
• Open activemq
  • If you have did previous step, just open cmd and type activemq
  • If not, change directory to activemq\bin\win64 or activemq\bin\win32 and then type activemq
• Test
  • In the default configuration, open http://localhost:8161 in browser and you will see a welwcome to Apache ActiveMQ page which means your activemq works properly.
  • Open http://localhost:8161/admin with user admin and password admin, you will get a visualized background management system for activemq.

How to run?

Publisher side

• Place Publisher.java in publisher host
• Place activemq\active-all-XXXX.jar in publisher host
• Add active-all-XXXX.jar to project dependence or to classpath
• Change brokerURL to activemq server' ip and port, line 14 in publisher.java

  // Message broker address tcp://ip:port
  private final String brokerURL = "tcp://localhost:61616";

• Compile it

  javac Publisher.java

• Run it

  java Publisher

Receiver side

Synchronous consumer

• Place SyncConsumer.java in receiver host
• Place activemq\active-all-XXXX.jar in receiver host
• Add active-all-XXXX.jar to project dependence or to classpath
• Change brokerURL to activemq server' ip and port, line 15 in SyncConsumer.java

  // Message broker address tcp://ip:port
  String brokerURL = "tcp://localhost:61616";

• Compile it

  javac SyncConsumer.java

• Run it

  java SyncConsumer

Asynchronous consumer

• Place AsyncConsumer in receiver host
• Place activemq\active-all-XXXX.jar in receiver host
• Add active-all-XXXX.jar to project dependence or to classpath
• Change brokerURL to activemq server' ip and port, line 17 in AsyncConsumer\AsyncConsumer.java

  // Message broker address tcp://ip:port
  String brokerURL = "tcp://localhost:61616";

• Compile them

  javac AsyncConsumer\*.java

• Run it

  java AsyncConsumer.AsyncConsumer

RandomSignalAnalysisSystem

What does it look like?

How to run?

RandomSignalGenerator

• Place RandomSignalGenerator in publisher host
• Place activemq\active-all-XXXX.jar in publisher host
• Add active-all-XXXX.jar to project dependence or to classpath
• Change brokerURL to activemq server' ip and port, line 16 in RandomSignalGenerator.java

  // Message broker address tcp://ip:port
  private final String brokerURL = "tcp://localhost:61616";

• Compile it

  javac RandomSignalGenerator.java

• Run it

  java RandomSignalGenerator

• Note: signal obeys a given normal distribution, you can change it by changing it's mean and variance, line 73 and line 75 in RandomSignalGenerator.java

  // mean of normal distribution
  double mean = 10;
  // variance of normal distribution
  double variance = 4;

SignalAnalysis

• Place SignalAnalysis in receiver host
• Place activemq\active-all-XXXX.jar in receiver host
• Add active-all-XXXX.jar to project dependence or to classpath
• Change brokerURL to activemq server' ip and port, line 20 in stage.Main.java

  // Message broker address tcp://ip:port
  private final String brokerURL = "tcp://localhost:61616";

• Compile them

  javac -encoding utf-8 analysis\*.java
  javac -encoding utf-8 view\*.java
  javac -encoding utf-8 stage\*.java

• Run it and you will see the UI window

  java stage.Main
