Primary key issue

Question

Hi all,
I'm new here, and I have a stupid problem, I think. If someone could help me, I'll be grateful.
I have to build a very simple JSP application using a few database tables, providing the base functionality: insert, update, delete, search.
I'm using Oracle 8.1.7, and JDeveloper 9.0.3
One table looks like that:
CREATE TABLE TEST (
sPrimaryKey varchar2(30) not null,
sField varchar2(100)
ALTER TABLE TEST
ADD ( CONSTRAINT test_id_pk
PRIMARY KEY (sPrimaryKey)
I'm using a sequence for generating primary key...
CREATE SEQUENCE test_seq
START WITH 100
INCREMENT BY 1
NOCACHE
NOCYCLE;
... and a trigger before insert for seting the new value of the primary key.
CREATE OR REPLACE TRIGGER BI_TEST
BEFORE INSERT ON TEST
FOR EACH ROW
DECLARE
new_id integer;
BEGIN
select test_seq.nextval into new_id from dual;
:new.sPrimaryKey := 'AAA' || new_id;
END;
I have created a BC4J. How can I insert a new row into that table using a BC4J from an HTML form, within a JSP page, without providing the primary key, by hand, and let the trigger and sequence do that?
Thank you!

I'm using a sequence for generating primary key...Change the attribute type for sPrimaryKey to be a DBSequence attribute type. It assumes you have an insert-trigger that fills in the correpsonding numeric column.
