We've developed Java application using Struts 2 as presentation Layer, Spring as Service Layer and Hibernate as Persistence Layer.
The Page Structure is like this:
Everything is working fine. When a link on a website is clicked the previous page stands still while:
1) Request goes to server
2) Corresponding action class found
3) execute() called
4) Service called
5) Corresponding method called
6) Querying database using Hibernate completed
7) List<> of Objects generated
8) Returning SUCCESS
9) Finding corresponding JSP page
10) Rendering JSP Page
And The rendered JSP Page is shown at once. As I've said everything is ok. But we're wanting the New Page (at least some elements Like Header of the Page) is starting to be generated and shown, while we're Fetching data from database.
Is this Possible in anyway except using AJAX?
I'd really appreciate if anyone could help me out.
Without Ajax you only get one request, one response.

I don't want more than One Request or Response neither. I want the functionality as doing hardcoding all the program in the JSP page and using response.flush() whenever we want the buffer up to that point sent to browser.
Is the content readable and indexable by search engines If we use AJAX?
