Before proceeding make sure you know how to create REST Web Services, in case you don't visit the following link:
It is also advisable that, before you start this tutorial, you make sure you have some basic notions in JavaScript.
What's a UID
A UID (unique identifier), as it indicates, is a single string throughout your application. It is also known as GUID (global unique identifier).
In order to exemplify the generation of UID's we are going to create a service.
UID generation
Let's now demonstrate the generation of a random UID, it is quite simple because Netuno already brings with it a function specifically created for this purpose:
_out.println(
_uid.generate()
)
Note that the
_out.println()function is just here to allow the display of the result on screen when calling the service in the browser
