Is this project still being worked on?

I got a hold of the Java Access Bridge stuff and noticed that the JRE already included it, although there were two JDK versions that didn't have the DLL iles and the Ext folder, so I added those. I am running Winodws 64, but the message I get is that the JavaAccess32 file cannot be found in JRE. So, I put this JavaAccess32.dll file, but it told me that it cannot run on a 64-bit system.
I recently downloaded some stuff from MuseScore, but noticed that they are compressed in MXL> I was able to rename it to zip and extract the XML from it, but Braile Music Editor still won't recognie it.
