MobileFirst paltform: Using Java in JavaScript adapters

I am working on MobileFirst platform for hybrid app development.  I am following this tutorial as I want to use my existing java classes for web service call.  And It is working fine on Android. 
https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-7-0/server-side-development/using-java-adapters/
Does this works across all platforms.  I want to run the same in Windows Phone also. Will this adapter be called on Windows Phone.  What is the scope of using Java in JavaScript adapters.  

A:

Adapters are sever-side entities.  The Java code is executed on the Server and so it does not matter from which client-side application you are calling the adapter from, be it Android or Windows Phone or anything else.
