Custom correlator plug-ins can now be written in Java as well as in C and C++. When a Java plug-in is injected to the correlator, it is analyzed and any suitable method in the plug-in can be called from applications running in the correlator. Correlator plug-ins in Java are deployed using JMon applications and are packaged in a .jar file.

Correlator plug-ins that are written in Java can be created by using Apama Studio or from scratch.
