Json Web Token Example for Java

Question

Is there an example Java program for HPW to create a header, a requirement for JWT (service account) for me to get an access token?

The following URL looks close: https://developers.google.com/accounts/docs/OAuth2ServiceAccount#libraries
But I was looking for any program for an example.

Are there any links to any links?

From http://code.google.com/p/jsontoken/

svn checkout http://jsontoken.googlecode.com/svn/trunk/ jsontoken-read-only 

And a fully working example:

JJWT aims to be the easiest to use and understand JWT library for JVM and Android:
