Hello
some days ago i had some problems with mkdirs() with some services
running in Tomcat-WebApps.
(Subject was "writing to File-System; IOException on File.mkdirs()
and/or File.createNewFile()" )
Doug gave me the final hint which helped me to solve the problem.
(although i have to confess, that i do not understand all in detail why
it did not worked "before" and why it is working "now" ....)
Originally i (or "my admin") wanted to start tomcat using jsvc like it
is recommended here ->
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/setup.html
ps auxfw
shows me that jsvc is running as root,

#-----------------------------
there are good reasons to start tomcat using jsvc, but when i do it, i
have some problems with permissions in the file-system.
are there some jsvc-cracks which already know the problem i described or
did i something "wrong".
by the way, i have no reason to run tomcat as privileged service, port
8080 is okay.
thanks in advance,
kind reagrds,
christoph
