It would help to know what statement is throwing the exception. The stack trace tells you that.
As a guess the "select *" is returning the columns in a specific order. You are not calling getString() in that order though.
Or one of the getString() values is wrong.
And get rid of the ToString() calls on the getString() methods - they are already strings.
