Please Note: This Post is lengthy, but question is simple

I have added all these files for more clarity only. I have a section MyQuestion(please scroll down below) for the question

Iam trying to implement cookies for my application.
I have 3 files for the same. 1) A filter class, which intercepts every request 2) PCH class which has methods to handle cookie related things 3) PCD is a simple Java bean with getters and setters for all the fields, of which we want to create a cookie

Create a Persistent cookie. Create only one cookie, with all fields separated by a , symbol. i.e if user enters from date and to date then the cookie will store <FD>,<td> i.e one single string.I implemented like this
1) (intercepts every request).
//Has a reference to PCH. PCH is a singleton
import .....

2) ( has methods for handling cookie related tasks)
//Above class has a reference to PCD. PCD is nothing but a Java Bean with all getters and setters for all fields creating cookie.
To handle multiple client requests,(for real time Scenarios),PCD is stored in a ThreadLocal .

3)PCD //getters and setters for all fields

My Question

1)Best approach to display in my Groovy Server Page?
My GSP looks like somehting below

When i reach this GSP, i have a cookie in format <FD>,<ED>,<Numberofbooks>
For example :singleCookie has value


Now i have to split this values and display in my GSP. I want to use GSP tags etc to get the cookie, populate "value" of the text fields and the select box from cookie value.So how to use the tags?
