I have faced strange poblem while writing Grails application deployed on Tomcat.
After creating simple test controller I want to write test contents in package com>
Finally I have solved the problem. One of the directory in path haven't executable permission for other group, so as @JustinKSU suggested, there was no possibility to go throught whole path.
chmod o+x /home/user solved the problem.
chmod o+x /home/user
