[ADF] migration to ADF, pl/sql based DB api

Question

We are planning to move one of our project to ADF (we using flex for now), we have all our DB working through the proc/functions API.
Its about 50+ entities, lots of rename/update/create api already exists and working well.
There seems a bit tricky to make ADF BC work through API, as I have found mere examples it looks like it more like exception from the rule, and every Entity and View BC is has to be rewritten by hand.
There are two frameworks around - [Avroms’s Package based API|http://www.avromroyfaderman.com/framework-for-database-api-based-adf-bc/framework-for-package-api-based-adf-business-components/] that is 3 years old it works for our testing, but I encounter strange behavior when using BLOB fields. As Avrom abandoned it and here is a not right place to ask questions about his framework – I’m really stuck with it 
Second framework is a evolution of the first one, Framework for Database API-Based ADF BC, and was hosted on oracle’s samplecode [is not avaible for now|https://database-api-based-adf-bc.samplecode.oracle.com/] , and there no way to get it.
What will be best practice to solve my problem:
1) Some simple way to build ADF BC on API, that is not obvious
2) Someone who can help with old framework to get it work in proper way
3) Try to convince PM to change the way new project work in ADF-native table/view way (it almost impossible, but who knows?)
4) ??? some suggestions
Thanks in advance

Answer 1

Yes, it is, but when I trying to use that framework and encountered some strange behavior when I have Blob columns in viewObject:
It looks like resultSet is missing first two rows.
With empty resultSet or when number of rows is below 2 I have an error:
(oracle.adf.model.connection.ConnectionException) JBO-29000: Unexpected exception caught: java.sql.SQLRecoverableException, msg=Closed Resultset: next
In case when number of rows is more then two – there is no error, but results is shown from third row.
Error can be reproduced in [Demo app|http://www.avromroyfaderman.com/wp-content/uploads/2009/05/packageapidemo.zip] :
1) Add blob field to Employees table
2) Modify GET_EMPS function to return new blob field
3) adding blob field to Employees entity and EmloyeesView
Thats make me stuck with it, as I have some blob fields in fundamental entities, so I can't proceed.
Avrom’s blog looks abandoned, and my comment there is still waiting for pre-moderation for a week+ and no responce from author through contact form.
I asked for newer framework version in the thread you pointing, but my post was deleted, assuming that all question on getting newer framework version must be pointed to Avrom or waiting for Frank to get his hands on project to make it EMG again.
