[appengine-java] Re: how to get session id under a Class which doesn't extend HttpServlet?
You probably want to architect the classes in such a way that they are
not tightly coupled to the http servlet session.
Anyway, when you were working with ThreadLocal earlier, did you first
set the ServletRequest from the filter?
class UserService {
private UserDAO userDAO;
public Collection getItemsForUser(User user){
return userDao.getItemsForUser(user);
}
}
class UserDAO {
public Collection getItemsForUser(User user) {
Long userId = user.getId();
String userName = user.getUserName();
// query the database based on user information
}
}

[appengine-java] Communication between multiple applications
I know that section 4.4 of the agreement says: 4.4. You may not develop multiple Applications to simulate or act as a single Application or otherwise access the Service in a manner intended to avoid incurring fees. What if you want multiple applications which act as different portions of a larger application for performance reasons? How is it determined by Google that your motive is to avoid incurring fees of quota use. Or, am I reading the terms of use wrong? I would like to build a client application which relies on polling for a configuration via HTTP which does not effect the performance of the primary portion of the application, which lets user set configurations at any arbitrary time. One reason being, only one simultaneous HTTP request is allowed at a given time for your application. I don't care about the quota, because I won't go over it in a single application, even with the polling, and I would gladly purchase more HTTP requests allowances, I just want the end user experience to perform well.

[appengine-java] Re: App instance recycling and response times - is there solution?
I don't have time to go into details, so this is a 10,000 ft view, but perhaps you could potentially extend the base spring context listener to work with the distributed cache (or some other mechanism between web apps) which keeps an instance of springs context so that it doesn't have to be repeatedly loaded. Also, you could write another Servlet which clears the context instance when you actually do need it to be reloaded. Hope this helps. - Derrick On Jan 12, 11:40 am, Konrad wrote: > Hi, > > I decided to do some long-run performance tests on my application.

[appengine-java] Re: Communication between multiple applications
Jason, Sorry for taking so long to get back to you. That is good to hear. B.t.w, I have noticed that only a few of the quota item prices are available, (i.e. not all are listed) such as the number of email attachments, etc. Does this mean that extra quota allotment for these items is not available to be purchased? If I do send email attachments, they are typically 30k on average. Is this another area where rules can be changed, on a case-by-case basis? I'm actually creating a flash based interface which relies on XML updates from the server. So it technically runs on the users local machine. Currently, the only way that I have to get the updates to the clients is for the client to ask for them. Ideally, I would want to use a streaming response, or a Socket server, etc. Unfortunately, I need a framework that will allow me to pay more money as my application growth demands it. I can't really put a lot of cash up front for a dedicated, or virtual dedicated hosting environment. This is yet another thing I really like about GAE.

[appengine-java] Re: Communication between multiple applications
I'm very familiar with BlazeDS, but haven't looked into GraniteDS for a few years. I know that with BlazeDS, this is done using a streaming AMF channel, which is essentially an endless http request, or "streaming response". Since the connection is left open, I am a bit worried that it may not work on GAE. However, I did find this, http://graniteds.blogspot.com/2009/05/graniteds-20-now-supports-server-push.html which seems to work pretty well. It looks like it still reissues a new connection every 30 seconds, but if a message happens within the 30 seconds, it immediately gets the response, then rebuilds a new connection. I'll have to play around with it a bit more to see how well it works. Also, this sends identical messages out to multiple clients using a producer/consumer model. It'll be a little more tricky with a request/ response model, in which the messages are different for each client (should still be possible). Thanks!

[appengine-java] Re: Flash arcade game GAE based
You can use memcache to help speed up access to the DB. All communication over GAE has to be done using HTTP... So, that makes it harder to things like pushing real time messages to the clients. You can use a technique called "Long Polling", but requests must return in 30 seconds, and currently, applications have a max of 30 simultaneous requests. Basically, the request starts a thread that sleeps most of the time, waiting to return data to the client when it's ready. One the client receives the update, it makes another long polling request.
