Android Bluetooth with Java SE

Hi Guys! Just wondering if i could get some advice from anyone with experience developing Bluetooth Android applications that communicate with a Bluetooth Java SE "server". Basically i want to be able to send/receive bluetooth messages between an Android application and a Java SE application.

I just need a recomendation of what Bluetooth API to use for the Java SE project. I have a little experience with Android using Bluetooth but wondered what the best package to use at the other end (server-java se) was?

Thanks
