Re: [appengine-java] Re: GAE or EC2
do you have specific point to be careful in schema design? or pointers to any read? thanks.

[appengine-java] How to send spreadsheet as an attachment on Google App Engine?
I have an application which is deployed on the Google App Engine. This application also works with the Google spreadsheet API to update a couple of spreadsheets. Once the user is done with changing the spreadsheet data, I want to email the resultant spreadsheet (not the link) to the manager. Is there a way to attach the spreadsheet as an attachment ? Since the app engine supports multi-part for attachment, http://code.google.com/appengine/docs/java/mail/usingjavamail.html#Multi_Part_Messages I guess I would need to get the content of the spreadsheet back as a byte []. How can I do that? Is there any other way to approach this problem?

Re: [appengine-java] How to send spreadsheet as an attachment on Google App Engine?
Vikas,
I have a servlet that uses JXL to build an Excel spreadsheet and send it via
email. Below is the code. However, I do not export any of the data from
Google Spreadsheets. If the Google Spreadsheets API doesn't let you get the
byte[], you'd probably need a JXL <-> Google Spreadsheets adapter that cycles
through all sheets and all cells and duplicates them to the other format.
Hope this helps,

[appengine-java] Re: Can't update int[] array in a class?
Try creating a setter function inside the Foo class itself and set the
array through that function. I'm guessing that the Datanucleus
enhancer isn't finding the update to vals that your using outside the
class. Also, I'd change from using arrays to using a List or Set.
