These JAR files can be obtained by downloading the latest version of Apache ActiveMQ (version 5.2.0 is recommended). Extract the downloaded archive and find the required dependencies in the $ACTIVEMQ_HOME/lib directory. You need to copy these JAR files over to $CARBON_HOME/repository/components/lib directory for Carbon to be able to pick them up at runtimerun-time.
Configuration parameters for JMS receiver and the sender are XML fragments that represent JMS connection factories. A typical JMS parameter configuration would look like this:
...
This is a bare minimal JMS connection factory configuration, which consists of four connection factory parameters. JMS connection factory parameters are described in detail below.
