If you want to POST your data as key/value pairs like with GET, and jQuery
puts it into the body of the request instead of the query string (i don't
know the implementation details, request parameters as query string are just
fine even if it is a POST request) you have to make sure that the
contentType is the default "application/x-www-form-urlencoded". Just give it
a try.
However, if you want to post the data as JSON fragment (as i would assume
from your original post from the contentType of "application/json"), i think
setting "processData" to "false" could do it. But in your servlet you won't
get the values as request parameters anymore. Instead you have to parse the
input stream of the request, e.g. with Gson to a Java object.
