I created a jsf page inside my ADF project. Inside I have a button and a text field. If i press button my servlet is activated. It returns a jasper report in pdf format. Now I would like to display my text field value as a jasper report parameter. So this is a part I don't know how to do. How do I get a value of my text field inside servlet?
After this I know how to pass it to report.

Beginner, yet you are working with ADF. Quite a contradiction.
The NAME of the input field is submitted, not the ID. I gave you all the help you need: read the book I linked to. It explains the basics very well indeed. This is a tough subject that fills entire books; don't expect to get any answers in a forum post, you're going to have to spend time learning this stuff. Not hours, weeks.
