Where can I download the jar file for the datasync API?

I want to use javax.microedition.datasync in my MIDlet application to synchronize data of my mobile phone with a computer. The problem is that I don't know where to find the library used by the JSR-230. So if someone knows where to get the library of this jsr.

I think this isn't downloadable, because the status of this JSR is inactive, that is mean:

...the JSR has not gone final and that its Spec Lead and Expert Group have not published a milestone draft for their JSR in more than 18 months...
