Initial ADF Page Call

Question

Hello,
for doing some logic to the Query Result after calling the Page the first time, i want to know where this can be handled?
In OAF for example, the initial Load (HTTPRequest) is handled in the controller Class, in Procedure
public void processRequest(OAPageContext pageContext, OAWebBean webBean) For example:
In here you can invoke a Method from Application Module, in which you can change/define the View Criteria and execute the Query of the particualr View Object.
Can aynone tell me how to implement this in ADF?
Thanks for replies!

Hi,
the blog is very helpfull thank you.
The definition of a Service Method is clear now. But i cannot controll the initial call before page loads ( it is working, when an ADF Button is placed on the Page, by Click).
Following Szenario:
In the Service Method of the Application module, there the viewcriteria will be changed programmatically. See this:
  public void QueryAM()
       ViewObjectImpl v1 = (ViewObjectImpl)this.findViewObject("EmployeesVO1");
        v1.setWhereClause("employee_id = 100");
        v1.executeQuery();
      }I created a Bounded Task Flow which has following components:
1. Method Call: Calls the method (QuerAM) from AM - Default (Start) activitiy
2. View Component: Has an jspx page (ShowEmployees) in it, which includes an ADF Read Only Table with all the Attributes
3. Control Flow Case: Direction from Default Activitiy (QuerAM) to View Object (ShowEmployees)
It always retrieves the whole Data, and does not take the view criteria. How to achieve the effect of the view criteria from the method and show in ADF Table?
Any Idea?
Thank you!
