[appengine-java] Re: Indexing Problem(always return incorrect number of rows)
Now i changed my sort order back from title to id.
And things are working fine again. i am getting the correct number of
rows.
So I am sure that there is a problem in Index building. It does say
that index serving but it has not indexed my whole data.
Google guys any opinion on it?
Thanks,
Ravi.

[appengine-java] Indexing Problem(always return incorrect number of rows)
Hi,
After indexing my all queries returning fewer rows.
I have this class
public class AudioMedia{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
@Persistent
private String title;
.
@Persistent
private String audioTitleExternalId;
}
initially i was retruning a list of AudioMedia where
audioTitleExternalId='SomeId' and order by id,and this query was returning
correct result
But then i thought its better to sort it out by title.
SO i created following index
and now i am returning a list of AudioMedia where
audioTitleExternalId='SomeId' and order by title
The only change in code i did was replacing id with title and creating
indexes. Then i waited for half an hour and indexes were created for 5+
rows. But now for any audioTitleExternalId i am getting incorrect number of
AudioMedia rows .
for example
SELECT * FROM AudioMedia where audioTitleExternalId='7475'
when i run this query in Data Viewer, it returns me 6 rows with title and
audioTitleExternalId for each row as not null.
But through the java code it returns me only 4 rows. Somehow indexing has
made my data lost somewhere or unreachable.
Can you please advise what is the problem here.
*Fields audioTitleExternalId and title both are not null in all entities.*
Thanks,
Ravi.

[appengine-java] Re: Failed to startup after ver 1.2.8 update
I updated ver1.2.8 at Dec-5th by seeing update request on Eclipse screen. But I was very surprised when I am seeing 1.2.8 is pre-release SDK and have no production environment by this post(=> hhttp://groups.google.com/group/google-appengine-java/browse_thread/thread/fe334c9e461026fa/b944b708a8d8de5b?lnk=gst&q=1.2.8#b944b708a8d8de5b) But this article was posted at Nov-25th and Display on the eclipse update recommendation and the Release Notes of Version 1.2.8 - December 3, 2009 (=>http://code.google.com/p/googleappengine/wiki/ SdkReleaseNotes) does not say anything about this. And So is it become official version at Dec-5th? If this is not official version Could you teach me when Google will make this version official and post old version(1.2.7) as a latest SDK. I must determine either wait official 1.2.8 or go back to 1.2.7 version to continue development. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Class XXX has multiple relationship fields of type YYYY
SDK 1.2.8 contains a new check that detects if one of your JDO or JPA model
objects has two relationship fields of the same type. For example:
class A {
List bList;
List anotherBList;
}
Unfortunately I was a little too aggressive with this check, so the
following also run afoul of the check:
abstract class B {}
class C extends B {}
class D extends B {}
class A {
List cList:
List dList;
}
If you get an exception that says
Class XXX has multiple relationship fields of type . This is not yet
supported.
and your class hierarchy resembles the one above, you can disable this check
by with the following config property:
We'll get this fixed shortly.
Sorry for the trouble,
Max

[appengine-java] Re: Processing incoming email
Hi.Peter,
As one example.
When you use
InputStream inputStream = message.getInputStream(); //
ByteArrayDataSource inboundDataSource = new
ByteArrayDataSource(inputStream, message.getContentType());
Multipart inboundMultipart = new MimeMultipart(inboundDataSource);
Please switch the processing of each type by using
MimeMessage#isMimeType.
(In the offered source it is variable [message]. )
MimeMessage#isMimeType("multipart/*") == true
Convert into MimeMultipart.
MimeMessage#isMimeType("text/plain") == true
MimeMessage#isMimeType("text/html") == true
Need not convert into MimeMultipart.
Of course,
Jeremy Blythe have provided us information that [contentType.indexOf
( "multipart")] also Behave the same.
Thanks Jeremy Blythe.
Ikai.
Thank you variously for useful information as for processing
concerning the attached file to datastore ,etc.
Though it noticed now.
MimeMessage#isMimeType("multipart/*") == true
The return value of MimeMessage#getContent() seems to have changed
into Multipart. (SDK-1.2.8)
(The real thing environment has been updated recently. )
http://code.google.com/p/googleappengine/wiki/SdkForJavaReleaseNotes
When you use [message.getContent() ]
Such a method might be able to be used.
Object content = message.getContent();
if ( content instanceof Multipart){
MimeMultipart mmp = (MimeMultipart)content;
}
else{
//plain text/html part .etc
}
Though there might be an insufficient condition.
Please try.
thanks.

This only happens when Queue.add() is invoked from the servlet

Re: [appengine-java] 1.2.8 SDK Prerelease - help us verify!
We're using the UrlFetchService to invoke the task URL, and the local
implementation of UrlFetchService times out after 5 seconds. For task
execution the timeout should instead be 30 seconds. I'll get a fix
together, but in practice the timeout shouldn't actually impact the
completion of the task. UrlFetchService will timeout but the task should
still finish running.
Thanks,
Max

Hello App Engine Developers,
As part of our ongoing efforts to improve release quality and
transparency, we will start prereleasing SDKs for early testing. We
hope this gives developers a chance to participate in our release
process by trying out new changes and sending feedback. As of this
morning, the prerelease SDK for our next release, 1.2.8, is
available
in the familiar download location (note that the filename ends in
'prerelease.zip'):
http://code.google.com/p/googleappengine/downloads/list
If you're interested, please download and give it a try locally with
your favorite App Engine code. Please note that, as a prerelease,
this
SDK is not yet supported and still subject to change. Thus, please
don't take critical dependencies or make substantial changes to
production apps based on this SDK.
Importantly, this prerelease is purely for the SDK and is intended
for
local testing and development in dev_appserver. The server-side of

Re: [appengine-java] Re: DWR SUPPORT
Hi, > Some said GAE did not support DWR while I had read about >> "Will it play in App Engine".It showed that " >> Direct Web Remoting (DWR) >> Version(s): 2.0.5, 3.0 RC1 >> Status: COMPATIBLE" DWR uses threads for some things like reverse ajax. For sure, that will not work in appengine at least the way 3.0RC1 is written. It also writes files that don't work on appengine. Long polling isn't supported either. I've seen people on the DWR list try to work around that, but I've never seen a clean solution. Maybe there is one though. Here are relevant posts from the DWR list http://old.nabble.com/forum/Search.jtp?forum=13934&local=y&query=dwr+appengine Anyway, your "undifined" error is most likely: 1) the path to the DWR script is wrong 2) the path is correct but when your javascript on the client loads, it send a call to the server to configure DWR. But by the time the call returns, your javascript on the client has already moved on and thrown the undefined error because DWR hadn't returned in time. I saw this with reverse ajax.

[appengine-java] Regarding Secure Data Access for the users of my service
We are creating an Active Directory Kind of an application on App Engine. What I want to know is there a way to store data securely so that I can sell this application as a service to other domains. I should not be able to acess data produced by users of other domains. I noticed if we use JDO, I can view the information. Is there a work around so that data can be viewed only by authorized people and not even the creators of the application? or do we have to implement our own encryption and decryption authorization processes. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Re: [appengine-java] Sticky sessions -- keeping a user on a single JVM
Stephan, No, there is no way to stick sessions to application instances. While you can't associate all the data in a single Memcache key, you can break up the data, using a Memcache value as an index for the rest of the data.

[appengine-java] Persist Hashmap and PersistenceManager question
I followed the following thread (http://groups.google.com/group/google-
appengine-java/browse_thread/thread/fb12ab60c68bf664/400cf3c83be90ce9?
lnk=gst&q=persist+hashmap) to successfully persist my hashmap. I had
a hard time to get it working because of the following issue:
If I use the following method to retrieve my object:
@Override
public T get(Class c, K id) {
//PersistenceManager pm = getPersistenceManager();
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
T result = pm.detachCopy(pm.getObjectById(c, id));
return result;
} catch (JDOObjectNotFoundException e) {
return null;
}
finally {
releasePersistenceManager(pm);
}
}
everything works fine.
If I omit the detachcopy(), I can retrieve the object but the hashmap
is always null.
@Override
public T get(Class c, K id) {
//PersistenceManager pm = getPersistenceManager();
PersistenceManager pm = PMF.get().getPersistenceManager();
try {
T result = pm.getObjectById(c, id);
return result;
} catch (JDOObjectNotFoundException e) {
return null;
}
finally {
releasePersistenceManager(pm);
}
}
For instance in the class below, once the StateCore has been saved, I
could retrieve the ID but the users hashmap would be null wiithout the
detachcopy().
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class StateCore implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent(serialized = "true")
private HashMap users;
public Long getId() {
return key.getId();
}
Could someone kindly explain why it's behaving that way?
Thanks in advance

OK. now I am really puzzled. message.getContent() is very much

[appengine-java] Re: Help Requested: How to persist a HashMap>?
I was asked, via email, to post the class that used this and the code
to use the function above:
The field this was directed to had a member like the following:
@Persistent(serialized = "true",defaultFetchGroup="true")
private Map callbackUrlMap = new HashMap
();
I used the above function in another function that I call a
GenericDao. It was my understanding that inserting works fine, it's
when you try to update that it has problems. Note that there is some
copying below because I'm using GWT and the enhanced classes don't go
over the GWT wire without removing the extra stuff added by JDO. It is
as follows (bear in mind, this is a WIP):
/**
* Gets the database version based off the object passed in, copies
* the argument object to the database object, then persists any
changes.
*
* @param clazz - class being persisted
* @param object - object to be persisted
* @return
* @throws DaoException
*/
public T update(Class clazz, T object) throws DaoException {
assert ClientUtil.isNotEmpty(object.getId());
Log.debug("update=["+object+"]");
PersistenceManager pm = PMF.get().getPersistenceManager();
T returnT = null;
try {
T dbObject = null;
try {
dbObject = pm.getObjectById(clazz,
object.getId());
} catch(JDOObjectNotFoundException e){
throw new DaoException("Object does not exist
in the database,
can't update it",e);
}
// Dozer's copy adds to arrays, it doesn't remove
(unless a schema
file is specified)
//copy(object, dbObject); // copy fields from existing
object to
database object (making any changed fields "dirty")
object.setId(dbObject.getId()); // just copy the
ID...this may end
up bad
JDOHelper.makeSerializedDirty(object);
returnT = copy(object.getClass(),
pm.makePersistent(object));
} catch(Exception e){
Log.error("Unable to update object ["+object+"]",e);
throw new DaoException("Unable to update object",e);
} finally {
PMF.tearDown(pm);

Vince,
As a workaround, try setting the missing environment attribute
explicitly before you add the task to the queue:
ApiProxy.getCurrentEnvironment().getAttributes().put("com.google.appengine.server_url_key",
"http://localhost:8080";);
This should only be necessary for tasks that are added when there is no
"live" request and it should have no impact in prod.
Sorry for the trouble,

[appengine-java] Re: Text Search Support for Java
The type of "full text search" sample that I would be interested in seeing demonstrated in tutorials or libraries for Google App Engine, would be searching across 1 or 2 fields (Title, Summary) of a small index (less than 1000 records, persisted to GAE updateable datastore) to power an autocomplete control eg. using Google Closure Library autocomplete (http://closure-library.googlecode.com/svn/trunk/closure/ goog/demos/autocompleteremote.html). So performance would be key for autocomplete, perhaps using Memcache for this small dataset. And with an aspect of "fuzzy search" to allow user friendly autocomplete behaviour. Then more extensive full text search could be powered by Google Custom Search, with a Linked CSE (search definition) hosted on Google App Engine. So for public content only, indexed by Google. Then I suppose it's playing to the strengths of the different offerings ie. using GAE for the lighter/AJAX type searching scenarios, and Google Custom Search for a richer index.

Hi all, I specified a replyTo when building a message I'm sending from my application.

However, the email I receive doesn't seem to exhibit the replyTo I specified, and instead, when I hit reply, that's to the authorized sender (my own account) that I'm replying to.

regarding compass: what about creating a task, which fetches a number of entities in batch mode and (re-)indexes them?

If you have a really small project you can use Compass (both for JPA and JDO). If you have more than about 100MB to index it will not work due to many many reasons (tested that 3 weeks ago).

Hey Ikal, eh errors happend around 2nd Dec, App Engine time 11:00 AM (Icannot say 100% exactly when it was). The random errors were observable for around 2h. I got the same error message as Jason. Now everything is working fine again. Thanks for coming back to us...

[appengine-java] JAXB doesn't work for me in 1.2.8
I get this error:
Constructor threw exception; nested exception is
java.lang.RuntimeException: javax.xml.bind.JAXBException
- with linked exception:
[java.lang.ClassNotFoundException: com.sun.xml.bind.v2.ContextFactory]
My Constructor is pretty simple:
RssService() {
try {
jaxbContext = JAXBContext.newInstance(Rss.class);
unmarshaller = jaxbContext.createUnmarshaller();
marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
} catch (JAXBException e) {
throw new RuntimeException(e);
}
}
I only get this problem on the Deployed environment, not on the
Development environment.
Am I missing something?
