Im developing Java EE 8 application which makes use of BIRT to generate a pdf and send it on to client.

But i want to add the data received from the request directly to the generated pdf ie without adding them to a database(so i cannot add the values by binding data source).

These are help im hoping to get
1) A solution if present.
2)Which is the class which can populate the BIRT-date since java.util.Date is deprecated.
3)And to know if BIRT api provides way to manuplate the report elements via name or id in a servlet or a model java class.

thank you for your help forgiving me if i have bored you with a long question.

What I have tried:

I've already completed report design, and webpages to take the data, and also servlets to process render and send the generated pdf(generic).

Ive even added the names in report design to enable me to add values at run time.
