[appengine-java] Re: Storing a web based file in the blobstore
If you were using a GAE app to retrieve the file and store it into the Blobstore, it would need to finish doing so within the 30-second request limit. So you might have to use an external application to retrieve the file and upload it into the Blobstore.

Ikai, what you said makes sense to me, but in the last week I've been seeing something a little different with Safari (version 4.0.4). I protect some App Engine URLs in the app by requiring authentication based on Google Apps, and in order to easily access those URLs in testing, I simply log the browser into Google Apps first (e.g. Mail). Or when I'm not signed into Google Apps and try to access the URL, it has me do Google Apps authentication, and then I can access both the URL and Mail. But in Firefox 3.5.8, the authentication is independent, so if I've authenticated for my App Engine URL and sign out of Mail, I can still access the App Engine URL in the browser.

[appengine-java] Re: Spreadsheets and GAE
How complex are these spreadsheets? If all you need to do is upload some basic data, then have them save it as CSV and upload that into GAE. I'm assuming your spreadsheets are complex enough that you need them to actually be Microsoft Excel files. Lior's response made me consider your actual use case and it sounds like it could be worthwhile for you to try using the Google Spreadsheets API. I had considered it but my spreadsheet needs are slightly different, and you can read about my decision here: http://stephenhuey.wordpress.com/2010/01/01/docxgae/ Although I used the GaeVFS virtual file system in that blog post, you can actually do plenty of the typical file stuff in memory and just write out to the Blobstore. Basically, I needed my users to be able to download data in full-fledged Microsoft Excel spreadsheets, and since the traditional Java libraries out there aren't supported on GAE, I chose to use Microsoft's xlsx format which is a zip file consisting of text files and images. In case that sounds terrible, note that I'm using FreeMarker to help me modify template XML files, and that does make things a little bit cleaner. So in a nutshell, you can work with bona fide Microsoft Excel files on GAE if you use the xlsx file format and not the older xls file format. - Stephen Huey On Mar 1, 1:14 am, Lior Harsat lior.har...@gmail.com wrote: Hi Praseed, my application uses the google spreadsheet api for importing data. I have learned the following lessons from it: 1. performance is not great. the api runs over http and is limited to GAE request timeout (5 to 10) seconds. on some cases a single request exceed this time and you are required to handle these timeout (retry) 2. API inconsistencies. The API is not that stable. some of the examples posted on Google simply do not work. it could be very frustrating. 3. google spreadsheets are nice for low volume data. Handling masses of data is difficult. copy paste is limited. limited formulas (comparing to Excel) . very basic scripting support. you should really play with it and verify that your end user won't get frustrated with it. 4. accessing the spreadsheet requires authentication. it may be an overhead for your end users unless you handle it for them. Having said all of the above I still recommend it as it is free, doesn't require leaving the google API realm, and will probably mature over time. you need to make a deep analysis of your requirement to make sure the above limitation won't become showstoppers.

[appengine-java] custom authentication when using Google Apps domain
We need users to be able to access our app on our domain, so I went into my Dashboard and clicked Add New URL to set this up, and then added a CNAME at GoDaddy. We use Google Apps for our domain internally, but do not want the users of our App Engine app accessing Mail, Documents, Sites, etc. However, my understanding is that the only way I could point a subdomain at our App Engine app was to use Google Apps and Add New URL. We're going to have an installed desktop application access our app via ClientLogin, and it's fine if that needs to talk to myapp.appspot.com in order to use HTTPS. The plan is for the installed application to hide the credentials it uses to safely communicate with our App Engine application behind the scenes. The only time our users will directly interact with the App Engine app is when they login via a web browser. For that, we'd like to use custom authentication because I don't want to have to pay $50/user/ year for them to access via a Google Apps Premier account. But it sounds like this means we can't safeguard portions of the site with the deployment descriptor if we're using custom authentication: http://code.google.com/appengine/docs/java/config/webxml.html#Security_and_Authentication Is this true?

If we're forced to use Google Accounts in order to have security, couldn't the GAE team at least provide a way to have an account registration form that you can customize for your domain? Am I missing something, or is Google just insistent that its brand be known behind this platform at the expense of our apps looking a little ghetto? Gracias...

[appengine-java] Are you using multiple app versions and a mixture of java and python in GAE?
You can essentially gain the ability to deploy multiple applications around a single datastore if you deploy multiple versions of your app that have different code from each other. I'm curious as to how many of you are doing this and how positive your experience has been so far. Right now, we have a lot of data processing code written in Java that we could easily split up into at least a couple of applications that run in the background and don't need to be synchronous with the user interface. I'm considering leaving that all in Java and then writing the user interface in a separate Django or Gaelyk app to minimize boot times of all the various apps. I'd love to hear a bit of your story if you're deploying multiple codebases for a single datastore...

[appengine-java] does makePersistent operate as a batch put with owned relationships?
The first sentence here is very clear about how calling makePersistent on an object with relationships automatically saves all the new or modified related objects: http://code.google.com/appengine/docs/java/datastore/relationships.html#Relationships_Entity_Groups_and_Transactions I've read that if you're using JDO, then just use makePersistentAll to do a batch put on a bunch of objects. However, I'm wondering if calling makePersistent on the root object does a batch put of all its related objects.

[appengine-java] have a solution to create docx and xlsx Microsoft Office files on GAE by using GaeVFS to generate zip files
I posted to this list a long time ago to ask about creating Microsoft Word and Excel files on Google App Engine since traditional Java libraries like Apache POI are not supported. Thought I'd be helpful and share a solution that works for me. Basically, I'm leveraging GaeVFS to generate the zip-based Microsoft Office Open XML documents on Google App Engine. The whole story is here: http://stephenhuey.wordpress.com/2010/01/01/docxgae/ I shared this solution with the list a while ago, but I just found out from a Google employee that the post wasn't allowed to go through since I replied to a thread of mine that had aged beyond a certain threshold.

[appengine-java] creating Word and Excel docs
I accidentally posted this in the old general GAE group by mistake. : ( I need to allow my users to export into Word and Excel formats from my GAE app, and I know Apache POI is not supported. So, I'm trying to figure out how to avoid running a server elsewhere whose sole purpose is generating Word and Excel documents based on data in my GAE datastore. Google Docs seems like a good fit, so would it work to use the API to create documents there from my App Engine code and then export the created docs and pull them for storage in my App Engine datastore so that my users can download them whenever I want? Or do you foresee roadblocks to this, e.g. some sort of limit on the number of Google Docs my GAE app can create even if they're temporary files that are immediately deleted? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: programatically upload files to datastore
I haven't actually tested this code yet since I got sidetracked with
some other stuff. But I basically worked off of the example farther
down this page:
http://code.google.com/appengine/kb/java.html
Then I just modified it to save the file data as an attribute to an
object I want to persist to the datastore. So does anyone know if
this is what I should be doing to have a desktop app upload files in
the background to Google App Engine? Should they be going through a
servlet if it's not an actual human user filling out a file upload
form on a webpage?
Here's my code:
import org.apache.commons.fileupload.FileItemStream;
import org.apache.commons.fileupload.FileItemIterator;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.commons.io.IOUtils;
import java.io.InputStream;
import java.io.IOException;
import java.util.logging.Logger;
import javax.jdo.PersistenceManager;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.google.appengine.api.datastore.Blob;
import com.ideate.PMF;
public class FileUploader extends HttpServlet {
private static final Logger log =
Logger.getLogger(FileUploader.class.getName());
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
try {
ServletFileUpload upload = new ServletFileUpload();
res.setContentType(text/plain);
FileItemIterator iterator = upload.getItemIterator(req);
while (iterator.hasNext()) {
FileItemStream item = iterator.next();
InputStream stream = item.openStream();
if (item.isFormField()) {
log.warning(Got a form field: + item.getFieldName());
} else {
log.warning(Got an uploaded file: + item.getFieldName() +
, name = + item.getName());
// You now have the filename (item.getName() and the
// contents (which you can read from stream). Here we just
// print them back out to the servlet output stream, but you
// will probably want to do something more interesting (for
// example, wrap them in a Blob and commit them to the
// datastore).
Blob uploadedImage = new Blob(IOUtils.toByteArray(stream));
Photo photo = new Photo();
photo.setName(item.getName());
photo.setImageData(uploadedImage);
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
pm.makePersistent(photo);
} finally {
pm.close();
}
/*
int len;
byte[] buffer = new byte[8192];
while ((len = stream.read(buffer, 0, buffer.length)) != -1)
{
res.getOutputStream().write(buffer, 0, len);
}
*/
}
}
} catch (Exception ex) {
throw new ServletException(ex);
}
}
}
THE END
Thanks for any help...
