Eric,

Thanks for your note.  The files are in separate directories and each apps
root directory is owned by the group that owns the app, however, when the
application creates a file (using tomcat) the files newly created have
tomcat-tomcat owner/group.  Tomcat belongs to the groups for all the
different applications but the application owners do not belong to the
tomcat group.  Setting the directory group ownership on Linux does not seem
to force the files within it to have the same ownership.

Aria.
