I'm afraid I'm not much of a kioslave expert, and I'd only been thinking of 
using existing kioslaves from java. Have you had a look at the example in 
kdejava//koala/test/kioslave - it was converted from C++ code ok? I've 
attached it to this mail anyway..

>From the code, this seems quite low level - I don't know if GridFTP would work 
off something like it:

  case Get:
    myJob = KIO.get( src, true );
     connect(myJob, SIGNAL("data( Job, byte[])"),
            SLOT("slotData( Job, byte[])"));
   break;

  case Put:
    putBuffer = 0;
    myJob = KIO.put( src, -1, true, false);
    connect(myJob, SIGNAL("dataReq( Job, ByteArrayOutputStream)"),
            SLOT("slotDataReq( Job, ByteArrayOutputStream)"));
    break;

So I'm not sure if you have to useJNI - I would have thought if you are 
wanting to go java <-> java and so it should be possible to avoid it.
