How does SingleThreadModel handles doget and dopost?

Question

Hi,
I have a requirement to synchronize the DB transactions but my servlet has doGet and doPost methods instead of service method.
public class EMEATPRates extends HttpServlet implements SingleThreadModel{
doGet(){
synchronized(){
---Gets the data from DB and displayes on a page
doPost(){
synchronized(){
----saves the changes to the DB
I need to get a lock when an user requests for page(doGet()) and release the lock only after he saves it(doPost).
Does SingleThreadModel handles this?

Answer 1

HTTP GET requests submit any form parameters within the URL of the request itself. HTTP POST requests submit any form parameters within the HTTP message body. Let's say you have two forms for a logon screen:
userid, password
HTTP GET: http://localhost:8080/LoginServlet?userid=foo&password=bar
[http headers]
[http body (empty)]
HTTP POST: http://localhost:8080/LoginServlet
[http headers]
userid=foo&password=bar
Clearly, for something like a logon screen, you would want to POST (no need to see the user's password in a URL if someone walks by). Otherwise, the implementation is up to you. I personally like cleaner-looking URL's, so I usually POST.
