Salve a tutti.Ho un problema con la connessione JDBC ad un database mySql.
Il problema mi chiama errore credo su getConnection().Ecco le eccezione ke mi solleva:codice:public class ConnectionMySql implements IConnectionService{ boolean b; Connection conn; public boolean getStatus(){ try{ // Carico il driver JDBC per la connessione con il database server MySQL Class.forName("com.mysql.jdbc.Driver"); //Mi connetto al server Mysql conn=DriverManager.getConnection("jdbc:mysql://localhost/", "root", ""); b=true; }catch (ClassNotFoundException e){ System.out.println(e.getMessage()); b=false; }catch (SQLException e){ System.out.println(e.getMessage()); b=false; }catch(Exception e){ System.out.println(e.getMessage()); b=false; } return b; } public boolean start(){ try { Process process = Runtime.getRuntime().exec("net start MySql4"); b=true; }catch (Exception ie) { b=false; } return b; } public boolean stop(){ try { Process process = Runtime.getRuntime().exec("net stop MySql4"); b=true; }catch (Exception ie) { b=false; } return b; } }
