SQL Exception: com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user ”. ClientConnectionId:085d5df3-ad69-49e1-ba32-b2b990c16a69

public class DataBases
{
private Connection link;
private java.sql.Statement stmt;
public ResultSet rs;
public DataBases()

try
{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://localhost:1433;databaseName=DB;";
Connection con = DriverManager.getConnection(connectionUrl);
}
catch (SQLException e)
{
System.out.println("SQL Exception: "+ e.toString());
