Apama installation includes the Java Runtime Environment (JRE), but it does not include a compiler or the jar utility. To write and compile JMon applications, you must have installed a Java development kit (JDK) on your system. In particular, you need a Java compiler, such as javac, and the jar utility.

You can download these from http://www.oracle.com/technetwork/java/javase/downloads/index.html.

To develop, build, and test an Apama application, the recommendation is that you use Oracle JDK 8. The minimum you can use is JDK 7.

When you install Apama, the installation script installs the JMon API as correlator_extension_api5.3.jar in the Apama lib directory.

Apama Studio includes the required Java compiler for running your application.
