[appengine-java] Re: String limit in JDO
You might want to try the persistent class com.google.appengine.api.datastore.Text as mentioned in http://code.google.com/intl/en/appengine/docs/java/datastore/dataclasses.html#Core_Value_Types as this class has no specific character length limit. Of course, use of this must still satisfy the overall datastore quotas and limits. I use Text objects to persist string data longer than 250 or 500 characters long.

The big announcements are the raising of the Task Queue rate, Python precompilation, and new Blob features. You can get it from the downloads page: http://code.google.com/appengine/downloads.html Release notes are below: Java --- - Ability to configure the Task Queue storage limit with the total-storage-limit field in the queue.xml file. - Task Queues now support up to 50 qps per queue, up from 50 qps per app. - Developers can programmatically access Blobs with BlobstoreInputStream, which provides an InputStream view of a blob in Blobstore. - Bulkloader transform helpers for lists and hierarchical keys were added. - remote_api_shell commands can be sent over HTTPS or HTTP. - Admin Console logs now include information on request time latency. - The datastore now supports both end cursors. - Fixed an issue where requesting /appstats would not properly direct to /appstats/. - Fixed an issue with inconsistent URL mappings between the SDK and production. -http://code.google.com/p/googleappengine/issues/detail?id=2598 -- Ikai Lan Developer Programs Engineer, Google App Engine Blog:http://googleappengine.blogspot.com Twitter:http://twitter.com/app_engine Reddit:http://www.reddit.com/r/appengine -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

cache = cacheFactory.createCache(
Collections.emptyMap());
}
}
�...@override

cache.clear();
}
private void doTest() {
assertFalse( cache.containsKey( yar));
cache.put( yar, foo);
assertTrue( cache.containsKey( yar));
}
public void testInsert1() {
doTest();
}
public void testInsert2() {

}
}
My JUnit3Config class is like:
public class CloudCoverRunnerConfig extends JUnit3Config {

public TestRun newTestRun( String arg0) {
TestSuite suite = new TestSuite();
suite.addTest( new MemcacheTest( testInsert1));

}
}
I'm thinking of giving the CloudCover a shot for Wave robot testing if
it's possible, since I have read in one of Wave docs that there is no
existing mechanism currently to test Wave robot on local machine.

[appengine-java] Random silent failures of pm.store()
I have a piece of code which only creates an entity and stores it with
public void makeEntity() {
UserPhoto photo = new UserPhoto(...);
this.pm.makePersistent(photo);
this.pm.close();
assert photo.key != null; // - fails from time to time
From time to time, the code above will fail. Maybe once every 10 times
(with the same parameters).
I am assuming that the store() call at the datastore level is failing
for whatever reason, but it is a silent fail as the code does not
throw any exception. When this happens I can confirm looking at the
datastore viewer that the entity was not persisted.
The size does not seem to matter (fails on 5kb as well as 200 kb).
I have logs of the app where back to back requests will fail first and
succeeds next, with the exact same payload.
It would be great if the App Engine team can point to an open bug
which remotely explains this behavior.
(the problem was present with 1.3.4 already)
The entity model is :
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable = true)
public class UserPhoto {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
Key key;
@Persistent
Blob photo;
@Persistent
Blob thumbPhoto;
@Persistent
private Key user;
@Persistent
private int size;
@Persistent
private String filename;
@Persistent
private Date date;
@Persistent
private Boolean canDelete;

[appengine-java] Entity class is not enhanced!!
Hi guys,
I have an simple application running on top of Spring using JPA for
Google AppEngine (GAE).
There's no compilation error, but when i load my application using
Google AppEngine Development Server, i got runtime error saying that
my Entity class is not enhanced!!
Which kinda confusing me actually, because i deployed to another
container (tomcat) and this Entity classes is running smoothly (of
course i need to modify the persistence.xml accordingly)
Here is my persistence.xml :
?xml version=1.0 encoding=UTF-8?
persistence xmlns=http://java.sun.com/xml/ns/persistence;
version=1.0
persistence-unit name=myDB
providerorg.datanucleus.store.appengine.jpa.DatastorePersistenceProvider/

property name=datanucleus.NontransactionalWrite value=true/
property name=datanucleus.ConnectionURL value=appengine/
/properties
/persistence-unit
/persistence
My Entity class :
@Entity
@Table(name = audit_trail)
public class AuditTrail implements java.io.Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = id, nullable = false)
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
private String message;
@Column(name = message)
public String getMessage() {
return message;
}
public void setMessage(String msg) {
this.message = msg;
}
}
And this is the error code:
10-07-01 11:18:22 ERROR [] [main] MetaData - Found Meta-Data for class
com.somecompany.demo.model.AuditTrail but this class is not enhanced!!
Please enhance the class before running DataNucleus.

[appengine-java] Volunteers needed for magazine project
Good morning, all. I am working on a magazine project that will hopefully use Google App Engine as the main way information is stored and retrieved. The goal is to be the Flickr of digital publishing. I have spent the past month trying to figure out the way to do this with Python, and haven't gotten as far as I would like. Due to the nature of this project (It's not intended to make me millions of dollars) and the altruistic goal (enabling anyone to publish content to e-devices like the iphone/ipad/mobile touch market/tablet computers/ multitouch surfaces, etc) without users being cobbled by a huge barrier to entry, I've decided to stop hoarding the idea and ask for volunteer programmers. I understand WHAT is needed to accomplish this, but I don't understand the HOW. I am more interested in publishing myself, but nothing exists in the format I envision. The engine can be run on java or python at this moment. It's a matter of which community responds first. If you would like more information, or to yell at me for assuming this part would be easy, you can reach me at: gerry.straathof AT acad.ca I have a general flow chart of how things should progress, but some parts are still labelled a miracle occurs... -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] JDO Detached ListKey or SetKey Issues
I'm seeing some odd behavior now that I've switched to properly detached objects (previously I was calling detachCopy but didn't have my classes marked w/ the detachable annotation). Given an entity that contains a ListKey, I can save a new entity w/ one key in the list. However if I remove that item from the list, persist, and retrieve again, the removed item is still there. I can work around this by replacing my List w/ an entirely new List object that is empty. Then it persists correctly. Oddly, I do NOT need to create a new List object, and things work okay if: - I'm adding to the list or - I'm removing from the list but leaving one item in it There are a number of GAE and Datanucleus issues logged, but none of them directly hit on this, so I thought I'd post it and see if I'm going crazy... -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: JDO Detached ListKey or SetKey Issues
There's JDO documentation on Arrays which describes somewhat similar behavior - http://www.datanucleus.org/products/accessplatform/jdo/orm/arrays.html: -- Quote -- JDO has no simple way of detecting changes to an arrays contents. To update an array you must either replace the array field with the new array value update the array element and then call JDOHelper.makeDirty(obj, fieldName); --- Using JDOHelper does resolve my issue. However this doesn't fully explain why: - This happens w/ List and HashSet, which I'd expect to be smarter since JDO backing subclasses are available - Some cases (adds, remove-leaving-one) work fine w/o using either of the two recommended work-arounds I should note that I'm also using detachOnClose.

[appengine-java] Re: Any ETA for a backup/restore facility?
Before I go off to learn Python in order to backup the contents of my datastore, can I be certain the bulkloader will work with my Java app? I am not concerned with reusing the contents of the live datastore in a local environment, only that I can download a backup of the datastore and perform a complete restore if a worst case scenario occurred and the datastore became corrupted/unusable. Ultimately, I'm not sure if I am missing something glaringly obvious but isn't a backup/restore feature fundamental to any service? You must have companies which rely on the app engine and the data they have within the datastore - are we expected to write our own tools to backup/restore our data? Does Google perform backups regularly we can access and restore? Are we just to cross our fingers and hope nothing goes awry?

This is the book I used to get up to speed on Python. Took me about 30 minutes to pick up 90% of what I needed: http://diveintopython.org/ That being said, we're always thinking about feature parity. I'm trying to think of a good way to wrap the bulkloader work with Java. We've got to be aware of tradeoffs - my sense is there may be issues with being able to reuse locally enhanced classes (just a guess, since if I were to build this out I would skip past trying to meet the requirement of being JDO/JPA aware in a version 1). Scripting operations or operations where strict-typing is more of a burden than a blessing are almost always easier in not-Java, which is why this made sense to launch in Python first. If you need export capability or incremental export capability now, however, don't wait on this since it won't be soon.

I am working on a magazine project that will hopefully use Google App Engine as the main way information is stored and retrieved. The goal is to be the Flickr of digital publishing. I have spent the past month trying to figure out the way to do this with Python, and haven't gotten as far as I would like. Due to the nature of this project (It's not intended to make me millions of dollars) and the altruistic goal (enabling anyone to publish content to e-devices like the iphone/ipad/mobile touch market/tablet computers/ multitouch surfaces, etc) without users being cobbled by a huge barrier to entry, I've decided to stop hoarding the idea and ask for volunteer programmers. I understand WHAT is needed to accomplish this, but I don't understand the HOW. I am more interested in publishing myself, but nothing exists in the format I envision. The engine can be run on java or python at this moment. It's a matter of which community responds first. If you would like more information, or to yell at me for assuming this part would be easy, you can reach me at: gerry.straathof AT acad.ca I have a general flow chart of how things should progress, but some parts are still labelled a miracle occurs... -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Show User In Logs when not using Users API
If you use the user's api then in all the logs it shows the user's username right after the ip address in the log entry. My app doesn't use the user's api, it just uses it's own user management with the datastore. Is there a way that I can get the user's username, or alternatively, datastore id to show up in the request logs like it does for apps that use the user's api? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Hello there I am finishing a book on GWT + GAE with Packtpub. I would like to include a chapter on **Browser Push (Comet) communication** feature. This feature is 'on deck' as indicated on the GAE roadmap (http:// code.google.com/appengine/docs/roadmap.html). To write this chapter, I would like to have an early access to the upcoming GAE Java release. Could someone at Google help me with this? Thank you so much.

[appengine-java] Jetty binds to localhost and not my wireless IP
I'm running GAE eclipse dev environment (GAE installed via the eclipse update mechanism). When I run my GAE application locally, it starts jetty, which seems to bind to localhost (127.0.0.1) rather than my machine's IP associated with my wireless card. When I try to connect to the running GAE app from another machine using, for example, http://192.168.1.100:, the connection fails. Things work from the machine on which the app is running by using http://localhost:. So... my question is, how can I make jetty bind to more than one IP, or perhaps to a different IP? Are there command-line params that I can pass to the Eclipse target?

Re: [appengine-java] Jetty binds to localhost and not my wireless IP
Try -bindAddress 0.0.0.0 It works for connecting to GWT from a different machine but I never had a problem connecting to the servlet engine.

Re: [appengine-java] Entity class is not enhanced!!
Hi Marthen,
I too faced similar problem. That time my data objects were in a java
project while my jdo-config was in a web project( web project in-turn had
project reference to this java project). The java project had app-engine
jar's in its class path, but still enhancement did not happen when the
project was build.
As a work around i moved my data classes to web project and then it worked.
Dont know the reason for this though. Perhaps could be an issue with
eclipse plugin only.
Thanks

Hi guys,
I have an simple application running on top of Spring using JPA for
Google AppEngine (GAE).
There's no compilation error, but when i load my application using
Google AppEngine Development Server, i got runtime error saying that
my Entity class is not enhanced!!
Which kinda confusing me actually, because i deployed to another
container (tomcat) and this Entity classes is running smoothly (of
course i need to modify the persistence.xml accordingly)
Here is my persistence.xml :

[appengine-java] Re: Entity class is not enhanced!!
Hello,
The enhancer sometimes doesn't start on classes.
The best way I have found to make it run each time is to name
explicitly all my jdo-annotated classes in Project Settings - Google -
App Engine - ORM under Eclipse.
No more problem!
Hope it works for you too
