executeUpdate returns an int indicating the number of rows affected
by the query. It does not return a ResultSet.

By doing exactly what ypu are doing, but storing the result of the
executeUpdate in an int rather than a ResultSet. You can then check
that the integer is not 0 if you want to make sure that something was
inserted. After you have made this change, try your program again.
If nothing is being inserted, you will at least, probably get a better
error message than the one you are getting now. This error message
is being thrown during compileation. Up to this point, nothing has been
executed.
