[appengine-java] Re: Is GAEJ's admin console a Google Apps application ?
Hello Ikai, In fact I'm looking for a way to extend the admin console. As I see the evolution in Google apps script ... I thought it would have been a very efficient way to add some new features to the console this way. I see the console app like being a sort of dashboard for the admin It's true that http://code.google.com/appengine/docs/java/config/appconfig.html#Admin provides a way to add some functionalities to it. I try it but was force to log in twice (one time inside the console, one time inside the app protected this way). What I try to achieve is to give the admin a way to exploit the data produce by a web app deploy inside GAEJ. Are their some links between GAEJ and the Google Apps (for example the spreadsheet) that could be used to exchange data between the two ? For example using the spreadsheet as a dashboard could be of some interest ! Thanks for your answer.

Hi Guy, Yes, it's possible: just use the write functions of the API to populate the spreadsheet and then it's a regular Google spreadsheet that you can use in any way you want. regards didier On Dec 1, 11:01 am, Guy Bobenrieth wrote: > Hi Didier, > > Do you know if the opposite is possible too ?

[appengine-java] Is it possible to use the bulk downloader to download nested entities in XML?
I'm trying to follow the hierarchical xml download instructions at http://bulkloadersample.appspot.com/ using the java appengine.

[appengine-java] Executing Batch gets with Spring and JPA
I've been struggling to get batch gets working with Spring and JPA. I am basically trying to build a category tree for an e-commerce site. The issues I am running in to seem to be related to transactions. I had set my DAO class for the Category entity to be @Transactional. Everything seemed to be working, till I tried performing a batch get query based on Max Ross' post (http://gae-java- persistence.blogspot.com/2009/10/executing-batch-gets.html). The first error I got said that I was operating on multiple entity groups in the same transaction. I found this confusing because it listed two Category entities and their id's. So my first question is: Can you only operate on one logical record at a time in a transaction? I figured since I was working on the same entity - Category, I should be OK. If each instance of a Category is considered a separate entity group, then I guess the behavior is correct. My next approach was to remove the @Transactional annotation for the batch get. When I do this, I now get: Object Manager has been closed org.datanucleus.exceptions.NucleusUserException: Object Manager has been closed This occurs withing the DAO Method. Here is the code: @Override //@Transactional public List getCategoriesByIds(List ids) { final Query query = entityManager.createQuery( "SELECT FROM Category c WHERE id = :ids"); query.setParameter("ids", ids); List results = query.getResultList(); return results; } Note: the @Transactional is commented out The error occurs right when "query.getResultList()" is called in the method. I don't understand how the object manager can already be closed. I have been calling the above method from a unit test. Any help would be appreciated. The entities look like the following: @Repository @Entity public class Category implements Serializable { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private Long memberId; private String identifier; private Boolean markForDelete; private Date lastUpdate; @OneToMany(mappedBy = "category", cascade = CascadeType.ALL) private Set categoryDescriptions = new HashSet(); Getters and Setters } @SuppressWarnings("serial") @Repository @Entity public class CategoryDescription implements Serializable { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Key key; @ManyToOne(fetch = FetchType.LAZY) private Category category; private String language; private String name; private String shortDescription; private Text longDescription; private Text note; private String keywords; } @SuppressWarnings("serial") @Repository @Entity public class CategoryRelationship { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private Long parentCategoryId; private Long childCategoryId; private Long catalogId; private Double sequence; private Date lastUpdate; } Thanks, Michael -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: Is it possible to use the bulk downloader to download nested entities in XML?
An important update: By fiddling around with bulkloader_config.py, I have discovered a problem: the value being passed to my the export transform is None. When I swap a place-holding list in for the value, the transform works perfectly, which leads me to believe that the transforms specified in my download config file are correct. The problem seems to be that the downloader is not passing my list value (children) to my transformer at all. The children property of ParentEntity does not show up on any of the built-in datastore viewers on appengine, either. I can infer that the property is there by accessing it in code - that works perfectly, and the children are all in there as you'd expect. But when I fetch it with the bulkdownloader, the property is vanished! When I download without any download config file, the children property must be included, because I can re-upload the data and all of the relationships are preserved. I must not be specifying the model correctly in the first place. How can I cajole the bulk downloader into seeing my children property? Thanks for any help - I've been working at this for hours and hours.

[appengine-java] Re: How to deserialize a LIST using GSON ?
Hi, Can you detail how you (de) serialize ? A code snippet would definitely help. Do you use an ObjectOutputStream or something else ? Let us know so that we can provide good help. I personally use ObjectOutputStream to serialize and then ObjectInputStream to deseriliaze and didn't encounter any problem until now. (I use this technique for example to be able to POST objects that represent the input args of a Task in GAE and then the deserialization happens when the Task is effectively run) regards didier On Nov 30, 9:41 pm, Valter Henrique wrote: > Hi everyone, > i can seralize a List in my servlet on GAE. > > But i don't can deserialize it. > > Can someone help me, please? > > Best regards, > Valter Henrique. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: no async queries on AsyncDatastoreService for 1.4.0?
great, thanks for the insight max. i have a client that will batch together multiple requests into one RPC call to my app on GAE. each of these individual requests may have one or more datastore accesses. this may include some prefetch requests. so i want to build a mechanism that will interleave these requests taking advantage of the AsyncDatastoreService for minimum request latency. i've gone through my server-side stack and made it asynchronous by wrapping RPC returns in Future objects. then i've created a FutureChain object that takes one or more Future objects as input, and will return one Future object. i then have some code that will poll the ultimate Future objects until all of them have finished. it ends up being a simple multi-threaded emulation where each individual request in a batch gets a thread and each thread gives up control when it makes an Async request. now for the PreparedQuery, because my app knows how many items i want, i should be able to wrap it in a special Future object that will try to pull in that many items when it is polled...but the problem is, i don't know when the batch has come back, so every time i call next(), i risk blocking on I/O when i could be initiating another I/O asynchronously or processing the results of an async I/O. so until there is explicit knowledge of when the I/O for a batch has finished, i may be able to get away with reducing the poll-rate of queries i suppose i could just query for the keys, then i could use an explicit Async method to fetch the entities themselves. if i query for keys, will they be split up in batches? any way to know how many keys will be in one batch?

[appengine-java] increase rate of 500 "resource constraint" on incoming xmpp messages
Since we started using the xmpp GAE service late last year, we have always seen on rare occasions the xmpp clients returning a 500 error. It has been so unfrequent that it was not a real worry for us. These past week, we have seen this error rate drastically increase. This has been reported by our users on PidGin on Windows (XP, Vista, 7) sending messages to our app xmpp address. We experienced several episodes of a few minutes where each message sent from PidGin was causing a popup reporting a 500 with the description "resource constraint". Looking in our app logs for 500s did not show anything. We can not tell if this issue did not happen on other xmpp client, or if it is just that they do not report them... The last occurrence of this issue was late today morning, and lasted a few minutes. During that time each message was causing this 500 xmpp report. After these few minutes, everything went back to normal. I do not think there is anything we can do from our app standpoint. Let us know if there is additional information we could report to help get this issue resolved. Jerome PS: I do not think this issue is related to the other sporadic problem with the xmpp message receiver that has been always existing: /_ah/ xmpp/message/chat/ java.lang.IllegalArgumentException: Must set a body at com.google.appengine.api.xmpp.MessageBuilder.build(MessageBuilder.java: 54) I have not been able to see a relation with the above 500 in the log with the 500 "resource contraint" from the xmpp client side. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
