Connecting and not connecting to the database from different pages, but with the same code?

Question

MySQL

Question to know. I have a standard database connection from two different jsp pages, different IDEA projects:

try
    {       
        Class.forName("com.mysql.jdbc.Driver");
        System.out.println("Driver Loaded");
        conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/testDB","root","");
        //Database Name - testDB, Username - "root", Password - ""
        System.out.println("Connected...");         
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

however, there is a connection on one, not on the other, firewood, Apache, everything is the same, why is that?

PS when adding a database in the database settings

Test Connection Successful

and in the view (panel on the right) the base is visible.
