Re: [appengine-java] Re: Google App Engine blobstore uploader and Google storage
I resolved my problem. The problem is simple: using blobstore.createUploadUrl doesn't always work in production while it's working in development. There's no symptoms, but a cryptic error 500 and it is why you didn't understood my problem, there's nothing more to say about it. Before using createUploadUrl, my upload was working, but well, I couldn't upload large files. After some time of trying to resolve this, I jumped on a post where the guy was sending malformed httprequest (missing space, etc.) and started to wonder if mine were well formed, which is weird since I'm sending a form. Then I remembered that I added URL Parameters! And those where the ones that was causing my request to not being forwarded to my upload servlet correctly! Conclusion: don't use url parameters with createUploadUrl! - I ddn't tryed to add the url parameters inside the createUploadUrl, maybe it would have worked. I used hidden fields instead which I think is a better solution than adding parameters into the url anyway.

[appengine-java] Google storage cpu consumption
Hi everyone, I was wondering, while using the Google Storage Java api, will I be billed for the time the handler of the request on AppEngine takes? I mean, that's great to have this easy to use API to access our data, but I will use the RESTful service from the client if I'm going billed for the small time it takes to forward the request.

Re: [appengine-java] Re: Question about security of my data on AppEngine and Guarentee.
I also think they are exagerated. But what I'm thinking is not important lol :D Christian On Thu, Jun 3, 2010 at 4:27 PM, Bill Milligan bill.milli...@gmail.comwrote: Hi Christian, For that kind of control on physical security, you really need dedicated servers that you can physically touch in a data center. This is really very not cheap. Some kinds of applications require this security, such as banking, investment, or credit tracking software, where you are dealing with customers with a great deal to lose, and I'm talking on the order of millions. Suppose someone broke into google's servers and hacked the database. This is quite unlikely, and even if someone *did* break in, I think your small business application is going to be the least of their interests. But suppose they did break in -- they would still be unable to access your data unless they also had the schema definitions. What are you doing to safeguard your source control and configuration management systems? If someone has those, then the possibility of stealing data becomes much more likely. There's no way to say *where* data is hosted in this kind of database. Even Google would probably be hard pressed to figure out exactly what location a particular piece of data is at any given moment. If you really need high end security, then you'd indubitably need that kind of failover as well. For instance, I once worked for a high-end consumer credit agency. In the event that their primary data center failed, in their missle-hardened unmarked location in the US, then we had a disaster recovery system ready to go in Canada. The end consumer would have noticed little to no change in the behavior of the system. Google's failover and backup system probably makes this look like child's play. I'm not going to say these kinds of concerns of yours are groundless, but I will suggest to you that they're probably exaggerated for the application you have in mind. If they're not exaggerated, then probably Google App Engine is not the solution you need.

Re: [appengine-java] Re: Question about security of my data on AppEngine and Guarentee.
Oh I forgot one question that my administrators asked me. If I delete an objet from my datastore, how long this data is kept in Google's backup ?

Remember the data in datastore is schemaless which means there's no clue of how data is stored. so, if someone gets inside your application he needs to know the declaration of the entity or at least how the POJO is structured in order to know how to get the data. In python, for example, when you use the tools for manipulating/ connecting to the data in your app, you need to have a exporter/loader class thus if you don't know how entities are structured the tool will retrieve errors instead of data and even the tool is not going to allow you to connect. unless you give the intruder the declaration of the POJOs or entities in your data store. Besides, you can control, the flow of data, by implementing a module which resolve and process all the request to the datastore and you can use authentication and that's all, simple and effective.

Re: [appengine-java] Re: Broken URL Mapping in GAE 1.3.3 ?
There's also a problem with cookies. ACSID is created just fine client side. But return null server side. At least, from what I read...

Re: [appengine-java] GWT and Twig
Yes, a lot actually. I was asking myself that question since I introduced in
my POJO's some TWIG annotation and didn't know if those information are
compatible with GWT-RPC Mecanism.
I'll give a deeper look into twig tomorow.
Thanks

Hi Damob,
They work perfectly together because your data models are *pure* POJOs with
no dependencies on the datastore at all.
In contrast, in JDO, JPA, Objectify and SimpleDS your data models usually
use low-level Keys and possibly other types. This means that you either
need to make an extra layer of DTO's or make your UI code dependant on the
low-level API.
For example, a Band and its Musicians can be sent to GWT as a single
object:
class Band
{
@Key String name;
ListMusician members;
}
With all the other libraries the data model needs Keys which complicates
things. You might send the Band and then need to send more requests to read
each band member from its Key.
I send data directly from my data layer to my GWT client and my client code
does not reference any com.google.appengine.* classes at all.
Hope this helps,
John
