Using SimpleXMLRPCServer in a Windows Service

[Rudy Schockaert]

I found the problem.
Actually both pieces of code work now. The problem was that when I run
the SimpleXMLRPCService in a Windows Service, the STDERR needs to be
redirected to a real file. I guess some kind of buffer overflow occurs
when you don't do this.

I added the following lines:

<snip>
def SvcStop(self):
    sys.stdout = self.stdout
    sys.stderr = self.stderr
    .....


def SvcDoRun(self):
    self.stdout = sys.stdout
    self.stderr = sys.stderr
    sys.stdout = file("c:/temp/my.log", "a+", 0)
    sys.stderr = sys.stderr
    ....
</snip>
