Thank you, @Evgeny Shvarov for the insights!

I've been using Docker and IPM in my projects, and they’ve been incredibly convenient. Docker simplifies the development environment setup and makes collaboration much easier, while IPM streamlines the installation process with minimal steps. Both have significantly improved my workflow.

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;

public class OracleJDBCTest {
    public static void main(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
