A J2EE server collect information of another server, possible?

I'm doing a project. My teacher provides a server having Restful API, but it isn't for android app. I would like to develop another server (by J2EE) which can collect information of my teacher server (by using its Restful API) to provide a Restful API for my androi app. It means that my server provides web service for my android app and it's also client of my teacher server. That's my project idea. I wonder if it's possible with J2EE. If it's possible, how to send and receive HTTP messages by J2EE ? Thank you very much in advanced for your answers.
