Hi All,

I got myself comfortable reading/creating javascript code so I jump on to study with Ajax technology.

I am currently trying to learn ajax from this site... Coreservlets Site

I am able to experiment on some of the sample exercise.

Now, I am having some question about this
As per their samples, you could always return a string/xml/json.

My question is, is this how we will always code our servlet code?



cities-xml.jsp



cities-jsonl.jsp


We always create a separate jsp file and always include it in the call to the requestdispatcher?




I have asked this question because, I look at some of the sample chapters of the books about ajax and majority of the book uses PHP as the server side technology.
In my case, I need to use JAVA. So I need to know how to apply it in Servlet and not JSP and code also the client side html.
I think ajax request should submit to a servlet rather than a JSP as per the tutorial

I am not sure but I am hoping I could use Jquery with Spring later after I had a good grasp of AJAX technology in my next project
Most of the Ajax books, discusses about using ajax framework. But as I have checked with my book, Pro Spring 2.5, it discusses about DWR. I have checked with the net
but cant find resource regarding Spring support for Jquery . Though I will think about this later.

Hopefully somebody could suggest an answer on my initial question. Sorry for the lengthy post.

Hi,

I guess, nobody responded because of the lenthy post.

I will try again.

Suppose I prefer to return xml data to each ajax request. Is there only two way to do this?

I only see this one:



And this pattern, create a jsp and include it in the call to the request dispatcher


I am not sure, but is this the only way to do this? And which one is better approach.
