Re: [Wrapper-user] Java file.exists() return false (when NT service and network drive is used)

Thanks, Leif.

The workaround of using the original network path worked very well. I am =
still curious though why using drive letter does not. I will keep you =
posted if I find anything that resolves it.

Thanks again,

I have had problems on some Windows versions with this as well, but have
never been able to figure out exactly what is causing the problems. It
works on some machines but not others.

I have seen cases where starting the service on system starup will not
work, but starting it when the account that the service is running as is
is also logged in works fine. I haven't seen any clues that this is a
Wrapper specific problem, there may be something that the Wrapper
needs to be doing on initialization that I am not aware of however.

A workaround that I found was to use Universal paths rather than the
mapped drives. So use the original \\computer\path rather than the
mapped drive. That has worked reliably for me. You still need to
be running as a user with network access, who has permission to
access the specific remote resource.

Cheers,
Leif
