Answer 1

I am a self taught pl/sql programmer. My client's site does not have any custom JSP. We do everything in PL/SQL.
I created a httpxmlrequest powered page:
1) step one write or find a database query based script that accepts a string from the url and gives results based on that string. The example i used (phone lookup) took a string (ss) from the url and queried a table to find employee names that contained that string.
As the used types in letters the list shortens and zeros in on the desired result.
(In the code I created a two letter length minimum, so no data gets displayed till there is at lease two letters typed in.)
you can test this page by typing &ss='Yor' on the end of the url. It will return all the records that contain 'Yor' like Yorke.
I will leave it to you to build a query.
2) Place the query on a portal page, with no header graphics or any other elements. A naked page. I call this my data page.
3) Create a normal page with all your header and footer decorations. On this page place a item that calls the code that accepts the search string (ss) and calls the httpxmlrequest. It also displays the results of the data page into a div on this page. see paulyorke.com/ajax/ajax_sample.sql.rtf
When you run the page no results should show up till you lift your finger of the second character. A result list should show up.
