How to pass many variables to servlet using a URL? Ajax related.

Question

I have 100 text boxes in my JSP and want to pass the values stored in these text boxes to a servlet with out the need for submitting the entire page using AJAX frame work.
I know how to peform the above in ajax if I have only 1 textbox. But how can I do that with 100 text boxes. I don't want to build a huge URL with 100 parameters.
I am thinking may be create an array and send it to the servlet, but don't have an idea if we can do it.
Please help me .

You can make a POST request using an XMLHttpRequest, but you won't be "passing many variables using a URL", which seems to be one of your requirements, and which makes your question confounding(after all how do you pass many variables using a URL without putting many variables in the URL):
req.open("POST", url, true)
req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');     
req.send("first=Eric&last=Kaiser");
