java.io.FileNotFoundException (permission denied) despite chmod 777

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 ``` package com.domain.controller import java.io.File; import java.io.PrintWriter; class TestController { def index() { // test try { PrintWriter writer = new PrintWriter("/home/user/domains/domain.com/public_html/the-file-name.txt"); writer.println("The first line"); writer.println("The second line"); writer.close(); } catch (IOException e) { throw new RuntimeException(e); } } } ``` I get an exception: Class java.io.FileNotFoundException Message /home/user/domains/domain.com/public_html/the-file-name.txt (Brak dostępu) I have set the chmod to 777 into `/home/user/domains/domain.com/public_html/`. And `tomcat7.tomcat7` is owner. I have also tried to create this file with the access rights 777 and ownership set to tomcat7, but I still get an exception: ``` ls -al /home/user/domains/domain.com/public_html razem 16 drwxrwxrwx 3 tomcat7 tomcat7 4096 01-08 23:25 . drwxr-xr-x 8 user user 4096 12-16 17:14 .. -rwxrwxrwx 1 tomcat7 tomcat7 0 01-08 23:25 the-file-name.txt ``` What conditions in OS should I also meet? I would be very gratefull if someone could clarify the problem. EDIT: I have created the directory under `/path1`, set 777. The files are stored perfectly. I have also crated the directory under under `/path2/testdir`, but path2 has no permission 777 and chown. It also works. I have also testes the `testdir` with characters `.` and `_`, also works. I am very investigative and cannot understand the behaviour.
