You need to read in the file and parse it according to your business
rules (just like you would read in any file in your system) and then
create the appropriate Fields.

You need to read in the file and parse it according to your business

Hi Eder,

If you are using Java 5, take a look at

java.util.Scanner to read your lines,
then use String
<http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html>[]
split(String <http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html>
regex) to split on column,
and read the first element of the array to decide what field you have.

Hope this helps.

Patrick
