How to reuse application constants written inside Java classes in javascript?

Or is there a better way to define such constants so that they can be reused by both java and JavaScript?

A very simple solution would be to save your configuration as JSON on the server side, and then add the server in the HTML response to the client.

The server can read JSON at startup and store it in a singleton object.
