Hi, We have came up with this best practise. There are basically two scenarios;
1. When the back-end is belongs to your product(eg. calling BPS runtime). We assume that you have written your JAX-RS based on an OSGi service. JAX-RS will *not* hold any business logic and act as API interface(Facade Pattern). In this case making a network call(AJAX) from UI to your own VM is discouraged. You should use callOsgiService() function on the server side Js. 2. When the back-end is external(eg. calling Twitter API). Here we don't provide any server side feature for handling HTTP calls because this will again abuse and use to call own VM back-ends. You can simply write AJAX calls from UI using $.ajax() in jquery or XMLHttpRequest in client-side Js. * In the edge cases that you really need to make HTTP calls from the server side Js, you can initiate; apache commons 'HttpClient' or java.net 'URLConnection' through Nashorn. * Also you might still need to write JAX-RS APIs for your OSGi services for customers.
