line 9. Cut/pasted from (312) - same problem.

The code could include: if (realPath == null) realPath = ""; Other options are throwing a JSPException if the realPath value is null, or providing an alternative method of configuring log4j if the code cannot formulate an absolute file path to the configuration file.

SQL statements for authenticating a user

The example uses two separate sql statements for authenticating a user. The first verfies that the username exists and the second verfies that the password exists, but there is nothing there to make sure that the correct password goes with a specific username. By doing it this way you are letting any valid user authenticate with any stored password! You can fix this by changing sqlpass to "SELECT * FROM athlete WHERE passwrd='"+pass+"' AND name='"+name+"'";
