Calling ADF page Custom Listener (Ex: ActionListener) from BPM Process Task (APPROVE/REJECT)

Question

Hi All,
Jdeveloper version - 11.1.1.7
I am very new to BPM / SOA development, but I have very good development skills on ADF.
I am not using ADF BC, using EJB for business services and also using custom ADF pages for HumanTasks.
Usecase:
From the BPM Process task, when process submission (APPROVE / REJECT) , I need to invoke a Custom listener (Ex.Action Listener - a EJB call) in the ADF page.
I am trying to use BPM APIs.
Please clarify me how this will achieve using BPM APIs. I need detail guidelines to do it. Please make to understand this process.
Provide some useful documentation or links to understand the following:
1. Custom Human task pages
2. BPM APIs - 11.1.1.7
3. Call a BPM process task from ADF Listener and Call a ADF Listener from BPM Process task - Using BPM APIs.
Please revert more clarifications needed.
Thanks and Regards

Hi Joonas.
Plese let me explain me better for your understanding
A big summary for what I meant it's the following:
1- In the procces you made, when you add the HT activity, you have to implement it, this means declare the input(s) parameters you want. This implementation create the .task file.
2- Create an application, and projects as HT you have. Each poject are based on the .task file, and automatically create a Data Control (for each project based on a .task) with all you need.
This w'll be an empty application, so you can customize it all you want. The task selected should have all the parameters previously defined. Those parameters can change if you want.
2- Create a page(s) in the task flow for the task implementation. You can even split the the payload of the task in differents pages, create your custom pages and any logic you need.
3- An important aspect is how to match these application with the HT implemented in the process. It's possible, it's a configuration en the Enterprise Manager.
4- Deploy your application
All these are explain in the book I mentioned
