Permission denied with embeded tomcat

Question

I have a Spring boot application which tries to access files located in "/var/someDirectory"

Platform is: linux ubuntu 16

Server Application is: Embedded tomcat

here is the code:

    File file = new File("/var/testFile1.txt");
    if (file.createNewFile()) {
        System.out.println("File is created!");
    } else {
        System.out.println("File already exists.");
    }

but with exception:

java.io.IOException: Permission denied

Question:

How can I grant permissions to my application on '/var/' ?

Answer 1

sudo mkdir /var/someDirectory
sudo chown -R your_user /var/someDirectory

It is not about Java, honestly.
