Re: [Wrapper-user] Updating running service

[Leif M. <lei...@ta...>]

Lars,
Windows unfortunately does not allow this directly as all open files are
locked.  As long as the Wrapper.exe is running you will not be able to
update it.  This will be a problem with all of the jar and DLL files as
well.

The solution is to actually stop the Wrapper and run another process to do
the update.   Then once the wrapper and your application have been updated,
you will want to restart the service.

If you are running on the desktop, this will be fairly easy.  But if
running as a service, you will need a way to do this in the background
using a process that has all of the required permissions to 1) replace the
files, and 2) to stop and start the service.  The later will need to be an
elevated account.

We will discuss options here as well.

Cheers,
Leif
