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?

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); } } }
