Check the connection string. That can be it. try: "jdbc:derby://localhost sample;databaseName=<>database>;user=<user>;password=<>password";

I tried and it didn’t work either. The project is right, is only giving error in this machine in the others is just open the project with two clicks and already makes the connection.

It is usually necessary to add environment variables for java to work. I’m a beginner in Java, but if you can take a look if you are aware of JAVA_HOME, and if the installation of java in the PATH is also informed
