[appengine-java] Two ManyToOne relationships in one class
In my application I have bi-directional one-to-many relationship
between Venue and Tip.
@Entity
public class Venue implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key key;
@OneToMany(cascade = CascadeType.ALL, mappedBy=venue)
private ListTip tips;
@Entity
public class Tip implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key key;
private Integer version;
@ManyToOne(fetch = FetchType.LAZY)
private Venue venue;
I have venue object persisted and then tip is added to the venue. I
don't any any problem in doing this.
Venue venue = venueService.find(key);
venue.addTip(tip);
venueService.merge(venue);
Then I expand the relationship to have another bi-directional one-to-
many relationship between Person and Tip. Tip is posted by a Person
and for a Venue. One Person can post more than one Tips for a Venue.
@Entity
public class Tip implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key key;
@ManyToOne(fetch = FetchType.LAZY)
private Venue venue;
@ManyToOne(fetch = FetchType.LAZY)
private Person postedBy;
@Entity
public class Person implements Serializable, UserDetails {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key key;
@OneToMany(cascade = CascadeType.ALL, mappedBy=postedBy)
private ListTip tips;
Venue venue = venueService.find(key);
Person person = personService.find(userId);
venue.addTip(tip);
person.addTip(tip);
venueService.merge(venue);
I am getting the following error:
Detected attempt to establish Person(29)/Tip(125) as the parent of
Venue(2) but the entity identified by Venue(2) has already been

[appengine-java] a single entity write takes ~10 seconds with a tx and ~4 without a tx
Hi,
I am experiencing a strange performance issue.
a write of a single entity takes ~10 seconds with a transaction and ~4
seconds without a transaction.
needless to say this kind of performance is bad.
I experience this kind of performance only for a specific entity kind.
other kinds work as expected (sub second)
initially I though this could be because I had 4 indexes for this
entity, so I've removed them just for testing.
surprisingly enough the performance has not changed.
it doesn't seem that this entity kind is different than other entities
I have. the entity is a child entity in a 1-N relationship.
Please help, Lior
this is the entity definition (obscured for privacy purpose):
public class Payment
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private Key account;
@Persistent
private Company company;
@Persistent
private Key order;
@Persistent

[appengine-java] Re: jingle support on app engine
Hello Nick and group, We are currently using the XMPP stack in AppEngine, and we are pretty please with it. But there is a hard limitation that is, just as maxsap mentioned here, making us considering moving our XMPP server out of AppEngine. The only limitation for us is that we are not able to emit or receive state messages such as: composing xmlns='http://jabber.org/protocol/chatstates'/ The following request is directly about this limitation: http://code.google.com/p/googleappengine/issues/detail?id=2615 This other one is about the same, in a more generic way: http://code.google.com/p/googleappengine/issues/detail?id=2331 I would really appreciate some input whether the GAE XMPP stack is going to be expanded soon, such as we can make an educated decision for our app. Cheers, Jerome On Jan 29, 6:55 pm, Nick Johnson (Google) nick.john...@google.com wrote: Hi, Sorry, but Jingle is not supported by App engine.

[appengine-java] Re: Error in Production Datastore Explorer
Hi Wesley, Thanks for the heads up. Any reason an empty-String cannot be used for a Link? I was coding defensively by making all Link object default to an empty String (since in order to do anything with them I need to constantly be calling the getValue() function on the Link). Now, I have to return null when using an empty link, so I have to always be checking if the Link I'm using is null or not (just makes for messier code). Is there some good reason the datastore doesn't support empty-String Link objects, or should I file an enhancement request for this?

Re: [appengine-java] Re: Error in Production Datastore Explorer
david, thanks for writing back. i wasn't around during the time when they designed this core part of App Engine's data models, but one obvious thing that stands out in my mind as a good reason is the validation of these special fields. if you had automated checks of this data, you would, presumably need some string that represents a valid URI. other reasons include consistency to the gData interface as well as the equivalent data in XML or Atom formats. if you want to allow blanks, it may be better to just leave them as StringProperty. -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Core Python Programming, Prentice Hall, (c)2007,2001 Python Fundamentals, Prentice Hall, (c)2009 http://corepython.com wesley.j.chun :: wesc+...@google.com developer relations :: google app engine -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

I have only been experiencing this problem in the last few weeks (after the 'fix' ?). - What is your application ID? salsa-amsterdam - How do you know it is being cycled out? You'll need to insert some code that only gets called when the app cold starts. I am using a static AtomicBoolean to check in my front controller servlet - How much time of inactivity does it take before your application is cycled out? it is recycled within the minute. - What time or days does this seem to happen? seems to happen all the time - What frameworks or libraries are you loading? Plain Servlet API, some Groovy and the low level Datastore API. Any other information you can provide would be helpful.

Hi Jason, the author Brett Slatkin and others:
1) For the list property, the video shows simple example of
standard 1:n
Message Receivers in python and Java. It then demonstrates a
very
efficient technique of Message and MessageIndex with the query
of
MessageIndex in python (NO Java from then on). I look at both
the low
level datastore with Query.setKeyOnly() and the query select
id from
to get the results of ListKey, then go through the loop to
get the
receivers. I may miss something, since the python code looks
so clean.
But once you are in any environment, it is very expensive to
switch.
This technique has major impact in data modeling.
2) Again for the set intersection, the python code looks so
clean. I
roughly sketch what need to be done on the Java side with
either low
level of datastore or with JDO. It is still not elegant as the
shown
codes. The demos are also in python. Again, the technique of
merge join
will have very significant impact on data modeling that GAE
may surpass
other platforms.
Haven't put enough time in it yet, I wonder if any one has
worked out
the demos in Java and suggested best practices in data
modeling for a
complex large application. The job Brett Slatkin sets out to
do has not
completed without the Java codes since GAE now supports Java.
