[appengine-java] Datastore, Java, JSP, JSON, AJAX, Web Page. Is it going to work?
Hi, I am new to GAE and I want to make a web application page on it. I was used to work with PHP for web applications but lately I am struggling to get in the thinking of a GAE web application. After reading tutorials and trying to do different things I came up with a thinking how I want my project to be and how to make the communication through the different layers. I will explain you my thinking and I would like to tell me if am I in the right way and if I am not I would like someone to put back into it. e.g. I thought to have a user @persistent class for storing the information of a user, such as name, email(as a primary key), registration date etc... (I will use the User class for logging in, but I want to keep some data also for every user) Then I need to create a java (dao) class that reads and inserts data to the datastore tables-objects. I thought to create a different one for each @persistent class Then Java files that execute the functions from the DAO classes and give information to the jsp files which through JSON give information to the Ajax functions in the HTML page (which I was thinking also to be the welcome-file in my web.xml) So here comes the questions. Is something like this right? Is it going to work? And if not what do you propose me to do. Any links or examples are very very welcome. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hi x_maras, re: using email as a primary key http://code.google.com/appengine/docs/java/users/overview.html The User object exposes a unique user ID that is guaranteed to be stable for the lifetime of the user's account, even if the email address is changed. You can use this value in a datastore entity key or property value. re: Datastore, Java, JSP, JSON, AJAX, Web Page Writing a RESTful service that can respond to AJAX requests with JSON payloads is very much a mainstream way to do things on app-engine. Be careful to keep the processing response times really short. The max response time is 30 seconds, the sweet spot is to average about 1 second response time. Happy Coding, --Stevko On Wed, Oct 6, 2010 at 4:34 PM, x_maras dinost...@gmail.com wrote: Hi, I am new to GAE and I want to make a web application page on it.
