ADF Table problem !

Question

hello Oracles;
i am using the JDev 11 to create an ADF Application, which allows me to display in a ADF table for a Product Table From the DB (using Oracle XE)
i managed to display the table in the page with a form to make some changes in it.
BUT the problem is :
HOW can i save this changes into the DB ?
and if i want to add or Delete an element too, i want to know how to save the oprations i made into the DB.
im using a JDBC connection,
i tried to add the Action attribute in the submit button code, wich is related to a class that manage the DB, but its not working !!!
thank you in advance;

Answer 1

okey to make things clear ;
ive created the application following this Tutorial. but they got the datas from the constructor simply with out DB.
so i made a JDBC connection with the DB and took the datas and put them in a collection and after that i display them in ADF Table.
now i want to add some buttons to the form like "add new product"wich gonna add the product in the DB and display it add it too in the ADF table.
i ve managed to do either adding the product in th DB without displaying it in the adf table or ^displaying it with adding in the DB.
thank you .
