in browser console no error or warning message. please help me how can find out wrong?

check url follow should be:

http://localhost:8080/your project name/servlet

also if item.getfirstname returns null see nil in tags

to sure param passing jsp page alter item value string example

request.getsession.setattribute('item' , 'my title');

now if see my title in <title> tag passing param done , reason in object.
