[code]import com.dhtmlx.connector.DBType;
import com.dhtmlx.connector.JSONGanttConnector;
import java.sql.Connection;
import java.sql.DriverManager;
import com.dhtmlx.connector.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Test_conector extends ThreadSafeConnectorServlet {

@Override
protected void configure(HttpServletRequest req, HttpServletResponse res) {
   Connection conn=null;
  try {
     Class.forName ("com.mysql.jdbc.Driver").newInstance ();
     conn = DriverManager.getConnection("jdbc:mysql://localhost/test","root","");
  } catch (Throwable e) {
     e.printStackTrace();
  }
  JSONGanttConnector gantt = new JSONGanttConnector(conn, DBType.MySQL);
  gantt.servlet(req, res);

// gantt.mix(“open”, “1”);
// gantt.enable_order(“sortorder”);
gantt.render_table(“task”, “id”,“text”, “start_date,duration,progress,sortorder”);

Yep, the both feature (mix, enable_order) are not supported by connector.
So you can’t use automatic order saving as in case of PHP connector.

“mix” method is used to set open property for all events, you can use beforeRender behavior for the same
