Solution
you can use this usefull method from the java.sql.Connection Class:
Connection con = new Connection(/* MY SERVER PARAMETERS */);
boolean valid=con.isValid(/* int millis */);
System.out.println("The connection is active?" + valid);
Hope this link can help you: https://docs.oracle.com/javase/7/docs/api/java/sql/Connection.html#isValid(int)
