Subject RE: Log output path problem
Date Thu, 11 Dec 2003 20:37:32 GMT
This is weird. I had it working two hours ago with /web/WEB-INF/logs/debug.log
as my output path. Now it's not working!!!  I have to use the absolute path to
make logging working for now.  Also it seems that if I use the relative path
/web/debug.log or just debug.log, things worke fine, but that's not where I want
it to go to.  

Could the same server invoke things differently?  Man, what's the deal with
setFile() anyway?  Why it cannot create the path dirs if the path doesn't exist?

Howdy,
You need to specify the absolute path or use an environment variable,
such as one set to the server's home.  Your current specification is
relative to the current working directory of the server, which varies
depending on how the server is invoked.
