Description:
The following failure error message comes when I try to start a mysql jdbc database server: 

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

For your support I would be very grateful 

Andreas Kellner

How to repeat:
This is a simple Code: 
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.util.Properties;

public class DBMetaData {

	public static void main(String[] args){
		
		try {
			FileInputStream in = new FileInputStream("dbconnect.properties");
			Properties prop = new Properties();
			prop.load(in);
			in.close();
		
				
		String driver = prop.getProperty("driver"); 
		String url = prop.getProperty("url"); 
		String user = prop.getProperty("user"); 
		String password = prop.getProperty("password");
	
		
		if(driver != null)
			Class.forName(driver); 
		
		
		Connection con = DriverManager.getConnection(url,user,password); 
		
		DatabaseMetaData dbmd = con.getMetaData(); 
		
		System.out.println("URL " + dbmd.getURL());
		System.out.println("UserName" + dbmd.getUserName());
		System.out.println("DataBaseProductName  " + dbmd.getDatabaseProductName());

		con.close();
		
		
		
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		catch(Exception ex){
			System.err.println(ex);
			
		}
	}
}

Thank you for the report.

Are you trying to connect from Java application to MySQL Server 5.1.31? Which version of Connector/J do you use?
