How to use Java NIO for writing files into network folder with specific credentials?

I'm having some troubles in finding how to manage network credentials while writing file into my java application which is running on Tomcat on Windows Server 2012 R2.

What I need to do is write a file into a network folder with

import java.nio.file.Files;
//[...]
Files.write("//serverIp/serverFolder/fileName.xxx, fileToWrite);

but I need to do that with a specific username and password, which are specific for that use and with no password expiration, and different from the one used by Tomcat or the OS .

If not specified, I'm ofc getting java.nio.file.AccessDeniedException: [...]

I found that is possible with external libraries in others questions (like https://stackoverflow.com/a/2171964/1984767 ) , but I prefer to stick to standard java whenever is possible.

Is that possible?
