Re: [Wrapper-user] Updating running service

[Lars S. <Lar...@if...>]

Hi Leif

I don't seem to have any problems with the jar-files, they get copied 
fine, but the wrapper.exe and wrapper.dll are a problem. After I update 
the jar-file of my service I simply restart the computer.

If I try to do it the hard way, by killing the wrapper process, I assume 
that will cause my service to terminate too?

I am dealing with Windws XP, so the elevated account is probably not a 
problem, but it would of cause be nice if it would work on newer Windows 
too.
