Hi,
my webobjects/wonder app needs to access/create files/directories
in a directory of the server where it runs. When I debug in eclipse
the application on my powerbook it works correctly but once
installed on the server I get the message below. I assume that the
applications runs as _appserver so, In Workgroup Manager, I added
this user to the group who has access to this directory. but still
does not works.
Any advice ? Is there any special procedures in Java or WebObjects
to access files ?
No, you just have a permissions problem that you are not seeing.
Follow the path down from / using these commands:
http://www.gvcsitemaker.com/gvc.webobjects/faq&mode=single&recordID=37272
If it is a mounted volume on another machine, you can be in for extra
fun.
Also be aware that anything you _create_ will not be group or world
writable. Only _appserver will have write access. So if you are
sharing this with other applications and users that can be a problem.
The only solution for Java 5 is to use ERXFileUtilities.chmod() on the
file / directory after you create it. There is also
ERXFileUtilities.chmodRecusively

work properly when executed locally on my portable.
