integrating oracle business intelligence with adf

Hello,
As it's clear from the topic, i want my bi integrated with adf.
in some documents there you have to add 5 extensions to oracle jdeveloper.

• Business Intelligence ADF Task Flow
• Business Intelligence ADF View Regions
• Business Intelligence Composer
• Business Intelligence Logical SQL View Objects
• Business Intelligence Soap Connection

First, But I couldn't find "Business Intelligence Composer" among jdeveloper extensions in oracle site.

Second, I can add three extensions (Business Intelligence ADF View Regions, Business Intelligence Logical SQL View Objects, Business Intelligence Soap Connection) but I can not add "Business Intelligence ADF Task Flow". I do not know why.
I tested the process for jdevelopers (12.2.1.0.0, 12.2.1.2, 12.2.1.3) but I would face with an error

I found the extensions in this link. Although i couldn't download jdeveloper 12.2.1.1 extensions from the link, by hitting the update button inside jdeveloper I could check the needed extensions and download them.kn

I do not know what is wrong with 2.1.0.0, 2.1.2, 2.1.3 versions. am I missing something ?

By the way I would be so grateful if you could inform me with

a tutorial about integrating adf with OBI.
Sincerely.
