Ah, okay.  I thought the goal was to boot and run and test with 
Cassandra, not to port some Java code to over the Windows execution 
environment.  My bad.

While I might guess — some sort of a startup environment — no, I don't 
have particular experience with Windows services.   Sorry.   Beyond 
maybe a day of aggregate incidental usage each year, I don't use 
Microsoft Windows, and really haven't used Windows since ~2006, and I 
don't try to stay current on Windows terms and environments.  Really 
rusty on Windows, in other words.  From back in ancient times, 
Microsoft Windows XP wasn't particularly good at uninstalling software, 
so booting and using a package as a VM guest was often preferable to an 
installation.  Hopefully that's improved with more recent versions of 
Windows.

As for your question and based on a quick pass through DuckDuckGo 
(DDG), have a look at 
<http://stackoverflow.com/questions/68113/how-to-create-a-windows-service-from-java-app> 
and — based on that StackOverflow question — I'd then guess that 
Cassandra is probably using 
<http://commons.apache.org/proper/commons-daemon/procrun.html> as the 
wrapper.   Ayup.  If not confirmed, it sure looks like Cassandra uses 
procrun: another DDG search finds 
<https://github.com/apache/cassandra>.  So for researching Cassandra, 
either load the pre-built kit which'll get the Java code going for you 
on Windows, or load the VM and use that.
