You can directly upload your application without using eclipse plugin. 1. Change your application version in appengine-web.xml. 2. Go to command prompt, point your app engine SDK version 1.5.0 (_your app engine SDK directory\appengine-java-sdk-1.5.0.1\bin) 3. Update your application using the appcfg update command. (appcfg --enable_jar_splitting update) and specify the destination directory of your project. like:appcfg --enable_jar_splitting update your_project_directory \build\web 4.

[appengine-java] Documentation Suggestion: More JDO ancestor query on collection documentation
May I suggest adding more query on ancestors (collecitons, lists,
vectors...) documentation. Please combine owned relationships with a section
on how to query the owned relationships, elaborating on it more than what's
currently stated.
For example, if my HashSetString list has {I,went,there} how can I query
that if it is an ancestor collection; needs more info in docs. Maybe I'm not
seeing whats currently stated. In that case please tie it into the
collections area.

[appengine-java] Re: Writing to google spreadsheet from GAE
The Java gdata works great as an api accessing the spreadsheet. If you only
want access to your own spreadsheet you can hardcode your authentication,
otherwise oauth is what you want.
Here is one of my examples doing
it. http://code.google.com/p/gwt-examples/wiki/DemoGwtGData

http://ikaisays.com/2011/05/26/setting-up-an-oauth-provider-on-google-app-engine/
Once you have your oauth token, you an access the spreadsheet api easily on
the server side.

String scope = https://spreadsheets.google.com/feeds/;;
AppTokenJdo appToken = AppTokenStore.getToken(scope);
String consumerKey = sp.getOAuthConsumerKey();
String consumerSecret = sp.getOAuthConsumerSecret();

GoogleOAuthParameters oauthParameters = new GoogleOAuthParameters();
oauthParameters.setOAuthConsumerKey(consumerKey);
oauthParameters.setOAuthConsumerSecret(consumerSecret);
oauthParameters.setOAuthToken(token);
oauthParameters.setOAuthTokenSecret(tokenSecret);
//log.info(Token + token + TokenSecret: + tokenSecret +

[appengine-java] Using JDO updating entity groups advice
Hi all,
I’m trying to model my domain to use GAE JDO. I have User and Event classes
(see below).
An Event is owned by a User and a User can participate in their and others
Events.
My issue is that I’m having trouble persisting the participate in another
User’s Event. I keep getting:
java.lang.IllegalArgumentException: can't operate on multiple entity groups
in a single transaction. found both Element {
type: User
id: 1
}
and Element {
type: User
id: 7
}
I see its because I’m updating multiple top level entities... but I’m not
sure how to update the entities separately given the own/participates
references... any suggestions appreciated!
@PersistenceCapable(detachable = true)
public class User implements Serializable
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
// owned one-to-many with event
@Persistent(mappedBy = owner)
private ListEvent ownsEvents = new ArrayListEvent();
// many to many
private SetKey participatesInEvents = new HashSetKey();
}
@PersistenceCapable(detachable = true)
public class Event implements Serializable
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
// owned one-to-many with user
private User owner;
// many to many with user

Re: [appengine-java] Private and public blobs
Hi!
You can expose your own links instead (like /download/{clientid}/{fileid}).
Check if the user is logged in as appropriate and then serve the blob:
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws IOException {
BlobKey blobKey = new BlobKey(req.getParameter(blob-key));
blobstoreService.serve(blobKey, res);
}

Hi to all developers,
i am developing a new web application for a company and i am using blobs to

the blob item's link i can download the file. As the enterprise's policy is
to download the file whoever have already paid for this, i need to have some
restrictions the blob items and the items should be downloadable only to the
appropriate users and not to the public. Can this be done?

[appengine-java] JDO advise
Hi all,
I'm using JDO for storage in GAE and would like some advice as I'm having
trouble modelling my persistence objects.
I have 2 classes, User and Event. A User owns an Event and can participate
in others Events. My classes look roughly like this.
@PersistenceCapable(detachable = true)
public class User implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
private String email;
private String firstName;
private String lastName;
private String password;
private String passwordConf;
private int status;
private boolean enabled;
// owned one-to-many with event
@Persistent(mappedBy = owner)
private ListEvent ownsEvents = new ArrayListEvent();
// many to many
private SetKey participatesInEvents = new HashSetKey();

[appengine-java] blob storage restrictions
Hi to all, i am a newbie in Google Web Toolkit and Google App Engine Technology so i need your help based on blobs. I am developing a web application for a company which needs to upload some files and serve them to their customers. The problem is that when someone uploads an item to the blobstore a url is created and whoever has that link can download/view the file but the specifications are the file to be downloaded to the user who have paid for that. Of course the user should be logged in before. So, how can i have some restrictions to the blob items and make them private to the prepaid customers?

Re: [appengine-java] JDO advise
ANy particular problem??
I would design these classes like this...
@PersistenceCapable(detachable = true)
public class User implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
private String email;
private String firstName;
private String lastName;
private String password;
private String passwordConf;
private int status;
private boolean enabled;
}
@PersistenceCapable(detachable = true)
public class Event implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
private Key owner;
private SetKey participants;
}
Usually i prefer unowned relationship, but with new pricing you can say you
can save some money by keeping a big entity(too many owned relationships).
With Owned relation your User Entity will keep increasing in size with time.

[appengine-java] GAE+GWT2.4 [ERROR] java.lang.NoClassDefFoundError: javax/validation/Path
I thought this was going to be easy. I'm trying to move a working GAE java app up to GWT 2.4. But when I do, I see the following stack trace on the first RPC call. At least one other guy has seen this while doing same and posted a query at http://groups.google.com/group/google-appengine/browse_frm/thread/a78f4c443bd3b249 Any help, suggestions, or insight would be most appreciated! Thanks.
