Re: [jsonbeans] Trubble running the tutorial

[Nate]

Hi, sorry about that. The download was a little but out of date from the source in SVN. I've made a new release, please try v0.4 and it will work. See the example below.

Code I used:

  Person person = new Person();

    person.setName("Nate");

    person.setAge(31);

    ArrayList numbers = new ArrayList();

    numbers.add(new PhoneNumber("Home", "206-555-1234"));

    numbers.add(new PhoneNumber("Work", "425-555-4321"));

    person.setNumbers(numbers);

    Json json = new Json();

    System.out.println(json.prettyPrint(person));

I'm using the jasonbeans-0.3.

Perfect, it works. Thanks!

I'm trying to get rid of Jackson and using jsonbeans instead for our level data and editor.

Nice. :) Hopefully you find JsonBeans easy to use. You are making a game? Have you seen libgdx?
http://libgdx.badlogicgames.com/
I originally developed JsonBeans there, so it is built-in. I only ported it to a separate project for use outside of libgdx.
