JDBC SQL Gateway connection error on a MacBook

Thank you for your suggestion! I have already checked the path and folder permissions, and everything seems to be in order.

The $JAVA_HOME environment variable is set, even I have added the driver path to the classpath. In the terminal, I am able to run the following code successfully:"

import java.sql.DriverManager;

publicclassOracleJDBCTest{
    publicstaticvoidmain(String[] args){
        try {
            // Load the Oracle JDBC driver
            Class.forName("oracle.jdbc.OracleDriver");
            System.out.println("Oracle JDBC Driver is installed and loaded successfully!
        } catch (ClassNotFoundException e) {
            System.out.println("Oracle JDBC Driver is NOT installed!");
            e.printStackTrace();
        }
    }
}

However, I’m still unable to connect from the IRIS SQL Gateway Connection.
I’m getting the following error for the first time after restarting the IRIS instance:

and after that I am getting the below error :

Thanks
