Answer 1

there are a bunch of ways you can do it.

1. You can use scriplets, as seen here.
2. You could use jquery to invoke an action on your controller which returns json, and then populate the array with the json response.

I personally would do option 2.

Answer 2

You need to do something like ;

import grails.converters.JSON

  ...
  render DurationTable.list() as JSON
