jre_library

Enables the JVM in the EMS server, where path is the absolute path to the JRE shared library file that is installed with the JRE. 

jre_library = path

Depending on your platform, this could be jvm.dll, libjvm.so, libjvm.dylib, and so forth.

If this parameter is not included, the JVM is disabled by default.

If the path contains any spaces, the path must be enclosed in quotation marks.

For example: 

jre_library = "C:\Program Files\Java\jdk1.8.0_121\jre\bin\server\jvm.dll"
