Programmaticlly upload synonyms to google search api using java

I'm having issues figuring out how to programmaticlly upload synonyms to the google search api from my server using java.

1. The Authorization: The desciption of how to do a server to google api is explained here. Where can I find a simple example of this using java?

2. Upload synonyms: I have created the xml to be uploaded, explained here. I am not able to see how I actually upload this to the google-api. Is there an example of how this is done?
