I finally went to bed, then had to get up again when I figured it out !
Just for the record, you don't need the getFileForURL() at all.
Here is what you do :
if (url.getProtocol().equals("njar"))
{
try
{
// force the resource we are after to be unpacked - tmp hack - thanks David
Jencks!
URL dummy=new URL("njar:"+url.toString()+"^"+"/dummy.jar");
String tmp=dummy.openConnection().getURL().toString();
tmp=tmp.substring("jar:".length());
tmp=tmp.substring(0, tmp.length()-"!/dummy.jar".length());
_log.info("converting "+url+" -> "+tmp);
url=new URL(tmp);
}
catch (Exception ignore)
{
}
}
I've only tried on Linux so far. I still have to get VMWare running.
the output is e.g. ;
