Ubuntu Tomcat CIFS : Allow tomcat user to write file using Servlet

I have following environment setup.

Server: Ubuntu    
App Server: Tomcat7
Java: JDK 7

A servlet need to write a file into a mount folder. Tomcat is running using a user called tomcat7 and a CIFS is bound at /mntt/mydir/ with a different user called coder.

The permission is set to 777 for /mntt/mydir

Service will create a folder and try to upload/write a file into that folder.

When folder is created it has permission set to 755 and file has permission set to 644, owner of both file and folder is coder and not tomcat7

So, when my program tries to write something in file it throws Permission denined exception.

UPDATE File Creation Code

//Create directory
File uploadFile = new File(dirpath);
uploadFile.mkdirs();

//Create and Write to File
OutputStream stream = new FileOutputStream(new File(dirPath+"/upload"));

Please guide. Also, please let me know if you need further information.

Thanks

Solution

  • Finally i solved the problem !!

    I run the tomcat service as coder user by modifying /etc/defaults/tomcat7.

    Also, i have to change permissions of few tomcat directories.
