How to do Personalization on DD4T Java 2.0?

Question

I have implemented a Web site by using DD4T Java version 2.0.

I'd like to implement Profiling and Personalisation, which uses Target group.
First I made a Target Group, and add it to a component presentation on a page. Then adding a TBB Add Target Groups to page template and run it on Template Builder, following element is added to JSON.

"Conditions": [
    {
        "Name": "key", 
        "Negate": false, 
        "Operator": 4, 
        "Value": "value"
    }

While using DD4T Java, org.dd4t.contentmodel.ComponentPresentation does not have property corresponds with target group Condition, so I cannot get target group's condition.

My questions are following.

1. Is it possible to do Personalization with target group on DD4T Java 2.0?
2. If it's possible, is there any documentation?
3. Does anyone know how to do it?

Regards,

Answer 1

Yes, its possible but there is no OOTB code in DD4T handling Condition Tags. You will get the condition list in your component object.

But after that You have to write your own code to handle it as per your requirements i.e. what component you want to remove or show from your current list of presentation according to your conditions.

Reference from my blog but it is in c# & will give you hint how to implement.

Update: as mentioned by Raimond above, de-serialization part is due in April.

Below are few links which will be usefull:-

I did for Java but not DD4T version, If you are able to generate the condition then Set up WAI API as per the blog given by Raj Kumar and try with the below code.

<%@ taglib uri="cd_tags" prefix="tridion" %>
<%@ page import="com.tridion.web.jsp.JSPPage,
com.tridion.personalization.CustomerCharacteristics,
com.tridion.user.User"%>

<%
JSPPage waiPage = new JSPPage(pageContext, "tcm:1-161-64");
CustomerCharacteristics customerCharacteristics = new CustomerCharacteristics(waiPage.getUser());
String custT = (String)session.getAttribute("customerType");
customerCharacteristics.setValue("customerType", custT);
customerCharacteristics.executeUpdate();
%> 

If using MVC then these API can be used in controller as well.
