[Pywps-devel] pyWPS

[Jachym Cepicky]

Hi,

huh, you are probably the first one, who tryes this on vista. First of
all, I would like to ask you, if you could try latest svn version.
There are some improvements, it should be WPS 1.0.0 complain, more
save and easier to setup.


the problem

[Error 32] Der Prozess kann nicht auf die Datei zugreifen, da sie von
> einem anderen Prozess verwendet wird:
> 'c:\\\\ms4w\\\\tmp\\\\pywps-pidfile-plsnlz'\


occurs only, when the processing is done (or failed) and pywps tries
to clean all temporary files. hmm did you run this with status=true
and store=true?

jachym

P.S. German is no problem for me
