Simple insert query....

Question

Excuse me guys,
i've a banal question but i've not a response...I'm developing a jsf
application.
i've a table in my mysql db,
with an autoincremented id and some others attributes.
My question is:
I want to insert a row of values in this table,but i can't do it using
a form page,but i have to use 3 page of forms.
How can i reference the same id and insert the same row using 3 pages?
For example,my table has:
id, name,lastname,city,address,profession.
I want inserting in a first page name and lastname,
in the second one city and address
and in the third one profession.
How can i reference the same line?
I want to use transaction support,so i need to store partial query on
each page into an object, to load all in one moment in the last page.
Can you help me with code?
Thanks.

When i run my jsf application it'doesn't go correctly?

     }[/code
I've used k for debugging, my page show k=100...DataSource dataSource = Singleton.getInstance().getDataSource();
               k = 4;
               Connection conn = dataSource.getConnection();
are surely corrected because they work in others beans....
please help me....
