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+"'";
