[appengine-java] Re: Uploading to blobstore gives OutOfMemoryError
Did you try to upload a binary object like an image? It seems that app- engine has hard-coded to parse the content for multipart/form-data. The error appears when your message body is not formatted to the multipart rules and parsing fails. The stacktrace gives an indication: javax.mail.internet.MimeMultipart.readTillFirstBoundary It is very unfortunate that you can only upload data from html-forms to use BlobStore. Does someone know a workaround for other MIME types? That you get an OutOfMemoryError is also the worst that can happen. If the app really allocates that much heap space this is a perfect target for a denial-of-service attack... -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: memcache best practice or framework
Hello John, Thank you for your message. I was looking at your project and indeed it does pretty much what I was looking for. I think memcache is good for basic caching problems but it could be made more efficient if it would keep most used data on the local machine memory to cut the costs for the network overhead. The problem is that from application side our local data gets lost when the application is cycled out. Google could provide a solution that survives this time-out and that uses resources more efficiently. Other discussions about ehcache show that there is a need for something more sophisticated. Maybe something for the roadmap?

Re: [appengine-java] Parent child joins in JDO queries
If you are not required to use JDO consider one of the GAE specific
persistence libraries. Both Twig and Objectify support embedding
collections of entities in a single container entity which gives the
ability to query using properties of the container or the contained.
I believe Twig is the only one that allows embedded items to be
polymorphic. For example:
class Farm
{
String city;
@Embed(polymorphic=true) ListAnimal animals;
}
class Goat implements Animal
{
int horns;
}
class Pig implements Animal
{
String favouriteFood;
}
then you can query for all farms in Wellington with a Pig that likes
cream buns
datastore.find().type(Farm.class)
.addFilter(city, EQUAL, Wellington)
.addFilter(animals.favouriteFood, EQUAL, Cream buns)
.returnResultsNow();

Re: [appengine-java] DataStore, ApplicationError: 3: Unexpected error, please try again
This can happen when you add the same entity to the put(or delete) request more than once (same by .equals). If this is the case, your put actually succeeded. This should be fixed soon, however I would suggest checking your code to figure out why you are putting the same entity multiple times (if in fact this is what is happening).

Re: [appengine-java] junit and local_db.bin
Yup, for sure.
Let's suppose you have an entity called domain which has the following
attributes:
1. Key
2. Name
public void listAllDomain(){
List Domain results;
Query query=factory.newQuery(Domain.class);
try{
results=(ListDomain) query.execute();
if(results.iterator().hasNext()){
for(int k=0;kresults.size();k++){
Domain dumb=results.get(k);
System.out.println(Key:
\t+String.valueOf(dumb.getKey()).toString());
System.out.println(Domain
Name:\t+dumb.getDomainName());
}
}
else System.out.println(no results exist);
}
finally{query.closeAll();}
}
Where Domain.clas is the class type for your entity called Domain.
besides, in the query object you can set filters for your query.
this method will show the data in your data Store.
As I can see, if the local_db.bin is getting bigger each time JUnit is ran,
then the data must be there, so with this method you should be able to see
all the data stored in your Data Store. you have just replace all Domain
references for your Entity's.
Hope this is was helpful.

[appengine-java] Signing into multiple Apps Simultaneously
Hey fellas, I've created multiple applications for basic functions, blog/forums/ chat that I want to share across 3 or 4 domain specific applications. Is there a way that I can have a user sign into one application and also automatically sign them into the other applications? So that way if they're using a chat webservice I've exposed on one of the sites, it's using their User credentials without asking for a separate login. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Problem JDO
Si estás en eclipse tienes que ir a las propiedades de appengine y en la opción ORM añadir o las carpetas que tienen la clase que quieres hacer persistente o cada clase individualmente. Saludos. If you are in eclipse you have to go to the properties of appengine and ORM option to add or folders that have the class you wish to persistent or individual classes.
