Need advice for my Server part

I'm stuck on my server part. I thing it would be fine if I make an REST architecture but I'm not sure.

My application is that an identitied user edit his name, age, hobbies...and I want to stock all the informations of all the users on my data server. Then, I could send the information of a user to another in a ListView with an adaptater.

Any idea to help me?

Thanks in advance

I have recently added a series of posts to my blog that may help. It covers creating a RESTful service using Java EE technologies on the GlassFish server. The example produces consumes XML, but could easily be adapted to handle JSON.
