This docs is for v0.2+


  1.  Start from v0.2, it is not longer a mandatory to provide a JMS ConnectionFactory. For a single JVM simple usage, you may use the default in-memory, non-persistent ActiveMQ connection factory, or you could configure your JMSProvider in several ways.


Configure JMSProvider

  • To use GroovyJMS, you need to decide which JMS implementation you'll use. There are several options:
    1. use the default in-memory, not-persistent ActiveMQ broker and connection factory, this is created by the ActiveMQJMSProvider class. Notice that the ActiveMQJMSProvider will start a ActiveMQ broker if it is not existed already, and will add a "vm://localhost" transport connector URL if not existed
    2. Provide a JMSProvider by
      1. specific a "groovy.jms.provider" system property that point to a class that implements groovy.jms.provider.JMSProvider
      2. set a JMSProvider to the JMS.provider static variable, e.g.
    3. Provide Connection Factory or Connection in runtime. it is the most recommended approach. You may utilize your JEE container or dependency injection framework to inject the required JMS resources to your class, and support the connection or factory to GroovyJMS.


There are three ways to construct a JMS instance.

  1. no argument
    • A JMS Connection Factory must be come from somewhere. If you don't specify it, an in-memory ActiveMQ broker and connection factory will be created by teh default ActiveMQJMSProvider

Unsupported Features or Limitation

  • nested usage is not supported yet. you may still use the lib in nested manner but you have manage the Connection and Session carefully.
    • For example:
    • you are recommended to avoid nestled usage. If you use it, try to use a multiple connection.
  • No labels
