将derby DB连接到Java

Question

I wanted to connect DB to Java application in Intellij. I set the classpath correctly, so that javac from cmd is working correct. I have also downloaded all the jar files needed as a libary, but I still get java.sql.SQLException: No suitable driver found for jdbc:derby

What can be the problem?

public static void main(String[] args) {
    try {
        Class.forName("org.apache.derby.jdbc.ClientDriver");
    } catch(java.lang.ClassNotFoundException e) {
        e.printStackTrace();
    }

    final String DATABASE_URL = "jdbc:derby:myDB;create=true;user=user;password=pass";

    try (
            Connection connection = DriverManager.getConnection(DATABASE_URL, "user", "pass");
    )
    {
        // ...
    }
    catch (SQLException sqlException)
    {
        sqlException.printStackTrace();
    }

}

You can try if org.apache.derby.jdbc.EmbeddedDriver works. And it seems your connection url is wrong.

    final String DATABASE_URL = "jdbc:derby://localhost:1527/myDB;create=true;user=user;password=pass";
    Connection connection = null;
    try{
        Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
        connection = DriverManager.getConnection(DATABASE_URL ); 
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
