Custom correlator plugins can now be written in Java as well as in C and C++. When a Java plugin is injected to the correlator, it is analyzed and any suitable method in the plugin can be called from applications running in the correlator. Correlator plugins in Java are deployed using Apama Java 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.
