[appengine-java] HashMap within an Embedded Class
Hey Are you able to store a HashMap within an embedded class? I have a Class which implements Serializable and annotate the HashMap like this: @Persistent(serialized = true, defaultFetchGroup=true) private MapString, Integer myMap; However, I always get this error thrown: myMap: java.util.HashMap is not a supported property type. I assume we can store a HashMap within an embedded Class? Thanks -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Feelings about new pricing model
Hi coders, Could people please correct me as I am trying to understand all this, have read quite a few thread/pages but still a bit unsure what is going on exactly. This is what I get so far: - Being charged for instances means we should probably use multi-threading in our apps to avoid significant cost increases, so google is encouraging us to write apps that make more efficient use of memory. - Python developers are piddled off because they can't use multi-threading. Can anyone enlighten me as to when an application that doesn't use multi-threading would require a new instance - when more than 1 request is happening simultaneously? When one JVM can't handle more requests? I am totally confused. I still think GAE is well worth the money. People are complaining about $50/month but I want my app to be making way more than that and I think the tools and support they provide make it way worth it. I just want to make sure I take all these measures into account to make my app as efficient as possible.

[appengine-java] Re: Coding with Adobe Software
Yeah don't bother with Adobe dude, waste of money unless you have invested significant time and money already learning how to become an adobe ninja. Google provides all the stuff you need for free :) so get into GWT and Eclipse. There are a few ways you can design the user interface using GWT: - In Java code, programmatically adding widgets and stuff into the page (see the StockWatcher tutorial) - GWTDesigner - a drag-and-drop interface that writes the Java code for you. - UiBinder - an XML system for designing your main layout in HTML-like format.

Re: [appengine-java] Re: Feelings about new pricing model
Let's say you have a sustained traffic of 5 hits per second, and each request takes 1 second to process (waiting on the datastore, waiting on facebook, whatever). If you're using single-threaded python, you will need 5 instances to serve this load - each instance can do nothing else while it processes a single request. So, maybe the datastore is behaving well today and you ditched your Facebook integration so you can complete each request in 200ms. Now you only need one instance to serve those 5 hits per second. Now let's say you get slashdotted, and for a day you sustain 500 hits per second. You now need 100 instances. Maybe there's a datastore hiccup and your latency goes up... now you need 200, 300 instances. They consume very little CPU because they spend most of their time blocked waiting for I/O, but they sure do occupy a lot of RAM. An efficient multithreaded (or async) server should be able to handle this load with less than 10 instances, and I/O latency will have minimal impact. Additional concurrent requests consume more CPU but they don't consume more RAM. Nobody is complaining about $50/mo. They're complaining about the looming threat of $500 or $5000 per month for traffic levels that barely register on a less scalable architecture. The Google blog says that appengine served over 2,000 hits per second for the Royal Wedding - I'd like to know what the bill would look like before and after the pricing change.

Re: [appengine-java] Re: Feelings about new pricing model
Can't you just limit your maximum number of instances at any one time? In the case of the datastore hiccup surely google would make some sort of adjustment due to their own failures? I see you point and agree wholeheartedly Jeff, I guess I just trust Google to keep it reasonably competitive on price. Otherwise wouldn't we all just move to another service?

[appengine-java] Connect Android Emulator to Google App Engine (GAE) local PC - domain works correctly.
I currently have a working implementation connecting my Android app to my GAE domain site. I was never able to get a working development environment and I always have to use my domain site to actually test my android implementation. I'm using the JAVA JDO implementation of GAE. I ran into some issues with my GAE code and need to debug the request coming from the android using the emulator. I am using the 10.0.2.2: in my android application to access the GAE running locally on the same PC. However, when i make the initial request to login and retrieve the Ascid cookie, no cookie is ever returned to me. Then i tried to use a combination of domain plus localhost (i.e. http://domain.appspot.com/_ah_login?continue=http://10.0.2.2:888/apiauthToken ). This works to get the ASCID cookie back from my domain site, then if i try to use that cookie with my localhost GAE, no user is found in the user service - guessing that the cookie isnt valid for the server running on my localhost. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

I have some questions to help me and others that visit this thread. The servlet container for the GAE dev, I assume its running?

[appengine-java] Re: Connect Android Emulator to Google App Engine (GAE) local PC - domain works correctly.
Sure. Yes, I do know the servlet is running. I was able to put a
breakpoint in the GAE servlet to verify the request was hitting the
container. Below is an example of my servlet which I was testing with.
This servlet just uses the user service to retrieve the user's information.
The variable 'user' is always null from the userService.getCurrentUser()
request, which will then send me back the response to redirect me to the
login page - which shouldn't occur from the Android application. When I use
my domain, I have no problems with my request as mentioned before. The auth
tocken I get from my google account on my device will allow me to retrieve
the cookie to automatically make requests on my api.
Unfortunately I am at work at the moment. I will reply here when i get a
change to inspect all the request headers coming into the servlet. Is my
assumption correct that I should just be able to change the base url to my
localhost and the same code should execute? Thanks for the help.
Example of my servlet.
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws
IOException
{
doPost(req, resp);
}
public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws IOException
{
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user != null)
{
PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(Player.class);
query.setFilter(userId == userIdParam);
query.declareParameters(String userIdParam);
ListPlayer users = (ListPlayer)
query.execute(user.getUserId());
Player currentPlayer = null;
if (!users.isEmpty())
{
currentPlayer = users.get(0);
}
else
{
System.out.println(Players are empty);
currentPlayer = new Player(user);
try {
pm.makePersistent(currentPlayer);
System.out.println(addded new player: +
currentPlayer.getUser().getEmail());
} finally {
pm.close();
}
}

[appengine-java] Re: Connect Android Emulator to Google App Engine (GAE) local PC - domain works correctly.
I know for sure last night, that no cookie was being sent back in the header. The only way I was able to get a cookie sent back to me is if I used the combination of domain and localhost (i.e. http://domain.appspot.com/_ah/login?continue=http://10.0.2.2:/api/home) or something similar. This was because the domain was sending me back a cookie that I was then trying to use to authenticate against the localhost. I'm not sure if this is correct, but just using the 10.0.2.2: address never sent back a proper cookie. I also noticed in the Developer tools -Resources of Chrome that the cookie names appear different between domain and localhost. One was dev_*something* the other was the ASCID cookie - if that matters. I will debug further to get all the header details of the request. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Strange behavior by App Engine Eclipse Plugin
Just to close the loop - this is the new version of the Google Plugin for Eclipse that uses OAuth to authenticate. The benefit is that now, your plugin can cache the OAuth tokens so that you don't ever have to re-enter your email/password to deploy. This is much more secure than caching your email and password. In addition, you can always revoke the tokens, so if you log in on someone else's computer and forget to log out, you can disable their ability to deploy without having to change your password.

[appengine-java] Re: Coding with Adobe Software
If you are brand-new to coding, I would not use GWT. I would start with HTML/CSS/Javascript. Many folks start their coding careers there (and many many stay there because they love it). You can get started quickly and the learning curve is not so steep. The learning curve on GWT or even Adobe Flash is very steep at the start. If you are doing a news app, html/css/javascript is probably very appropriate. Note that Javascript and GWT are designed for creating browser delivered UI's, but you can package them up using various technologies to create an application suitable for the app store and android market. I use Flash Builder and the Adobe Flex Framework for most of my client UI work and I love it. I decided to use it about 2 years ago, before GWT was really solid and HTML5 was viable (perhaps it's still not quite viable yet). The tooling is very good and the Flex framework is really outstanding. The Flex framework includes an xml based declarative UI system (mxml) which is really nice for building quick apps. You can graduate to ActionScript3 to do more significant logic. You can package your app for a browser or for iOS or Android devices (and Blackberry Playbook tablet). So, this would be a pretty good choice for your client UI as well. GWT is a truly great set of tooling and it gets better and better with each release. If I were to choose UI tooling for myself today, I would choose GWT because it provides great tooling and path to all the devices I want to target now and in the future. However, I have been doing software engineering for 25 years and I know Java well, so the learning curve is not so bad for me. I would not recommend GWT to someone just learning how to code. On the server side, GAE is a good choice - you don't have to worry about hardware and scaling. However, I would probably choose Python because the learning curve is less steep than Java. (PS: I use Java GAE it is is very good, my recommendation is based on your experience level, not the quality of Java GAE). There are lots of entry level resources for the Python language and the server side framework makes coding many scenarios easier than Java. On the server side, you might also look at CouchDB. This is a distributed database that is accessed via RESTful api's and extended using Javascript. This is a really, really fine solution that makes it easy to create a server that is primarily about saving and retrieving data. You can set this up on your own machine to see how it works. Some folks are combining this with another javascript server technology, called node.js, to create a complete server solution that is programmed in Javascript. You can probably find hosted versions of this combination, so you won't have to setup servers. So, more to your question, How do I code the application so that it functions with the interface?. I create what are referred to as Rich Client Applications (RIA). The client is basically a full application (not a set of pages, like a traditional website), that asks the server for data and then uses it to drive the client UI. When the client wants to save data, it sends it to the server and the server stores it in a database. In my case, the server is pretty simple (as servers go), in that is simply saves data that the client gives to it and gives it back when the client asks for it. I 'expose' the server as a set of RESTful api's that return the data as XML or JSON (note that CouchDB does this as well). I like this architecture because it clearly separates the client and server. By creating a RESTful server api that uses the HTTP standard, I can use ANY client technology to talk to it (javascript, GWT, Flex or ObjectiveC are all doable) Moreover, I can use any server technology to implement the RESTful server api. Basically, I give myself much more flexibility because the client and server technologies are decoupled, so as the world changes, I can change with it. Also, this lets me integrate with 3rd parties much more easily. I hope this helps. Good luck. Coding is the second most fun thing in the world.

Re: [appengine-java] Coding with Adobe Software
InDesign is a page layout program for printing, more or less. You probably could use it to mock up your web pages but it's drastic overkill when you're new to coding. Do your mock ups with static html, as others have pointed out. If you're looking for an html editor, I'd use something like Notepad if you're on Windows; that may sound facetious but as a programmer you need to learn all the nitty gritty stuff. Realistically you could use Eclipse, but don't use any wysiwyg thing that it may have, for dragging and dropping things on the page; edit the raw html so that you learn what it's about. For starting out with java web programming, it wouldn't hurt to start with plain old jsp and servlets. That might seem a bit antediluvian to those of us using web frameworks like SpringMVC (ugh) or Stripes (yay!) but it would get you up to speed with the concepts of the Java Servlet Container and configuring things with web.xml, and whatnot.
