[appengine-java] Re: Session/Cookie problem with redirect
I checked the response headers (in Google Chrome). When the redirect fails, then no cookie is set in the response header. Curious how this only happens sometimes. The sign in is a redirect from another redirect. First the sign in goes to a Twitter OAuth sign in page, then it's redirected back to the application and then the application makes a redirect to original page. When the sign in fails, not only is the cookie not set, the GAE session attribute is not set either when the redirect fails. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Ang.: [appengine-java] DataStore query without transaction - Spring 2.5 + JPA
I just got the OpenEntityManagerInViewFilter to work (in Eclipse, have not
deployed yet ) after having struggled for several days.
Do you use the EMF class from
http://code.google.com/intl/sv-SE/appengine/docs/java/datastore/jpa/overview.html
? If so, that might cause your problem since it creates an
EntityManagerFactory.
I have modified EMF to:
public final class EMF {
private static EMF _instance;
private static EntityManagerFactoryInfo emfInstance;
private EMF() {
Object o = SpringApplicationContext.getBean(entityManagerFactory);
emfInstance = (EntityManagerFactoryInfo)o;
}
public static EntityManagerFactory get() {
if (_instance == null) {
_instance = new EMF();
}
return emfInstance.getNativeEntityManagerFactory();
}
}
where SpringApplicationContext is implemented as specified here:
http://sujitpal.blogspot.com/2007/03/accessing-spring-beans-from-legacy-code.html
.
You still need the .size() hack after using getResultList().

[appengine-java] Re: Can't enable datastore admin
I also tried in my apps. All of them report Datastore Admin enabled successfully and I can see a new ah-builtin-python-bundle option in top left built-in select box. But when I click on Datastore Admin link, two symptoms show up: 1. For some apps I got a blank screen. Trying to understand what is going on, I found an iframe pointing to ah-builtin-python-bundle-dot- latest-dot-APPID.appspot.com, so I tried opening it in another browser tab. By doing so I got a permission screen to allow the app to access my google account information. After allowing, everything is OK from inside admin console. Browser (chrome) is denying some call due some cross-domain policy in authentication screen when accessed from admin console (iframe). 2. For other apps, occurs a DNS problem trying to resolve ah-builtin- python-bundle-dot-latest-dot-APPID.appspot.com, where APPID is my app id. Stuck in here. I'm ok with #1 because there is a easy work around (just open once the link in a new tab a hit allow). For #2 I found out that using a URL like this ah-builtin-python- bundle.latest.APPID.appspot.com instead of ah-builtin-python-bundle- dot-latest-dot-APPID.appspot.com would do the trick. But it is not possible to change what comes to iframe src attribute inside admin console, so it is pretty inconvenient as everytime I want to access datastore admin I must open another tab and enter a correct URL (or just add to favorites). Please note that I tried more than once disabling and re-enabling datastore admin, with no luck. Can anybody help me with this?

[appengine-java] Re: BigTable LIKE
In addition to the above, I'd say you might want to make new keyword entities for each keyword and store the reference/key to the original entities instead of storing your keywords as a list of properties in your original entity. A list of strings is stored implicitly as an embedded table so will be slower to search for than searching for a keyword property in a separate entity - this later is indexed by the framework.

Re: [appengine-java] Re: BigTable LIKE
I think keeping Keyword in seprate entity will be slower At time of writing you will be writing lots of entity instead of just one You will be worrying about how keyword will be mapped to each entity... iether by having a list of Keys in Keyword entity or specifying one to on emapping where keyword will be repeated If you want to get all entities which have some keywoprd and then sort by some field will cause you lots of in memory opeartion..first fetch keyword entity then get actual cnityt then sort it... On the otherhand List,Set property will be indexed too,and searching with in entity ort in anotehr entity its same. and this indexing is similar to a normal string indexing.. If you want to get all entities which have some keywoprd and then sort by some field , then you just need a composite index and it works its just read nad write for seprate entity will be more then a single entity.

[appengine-java] Re: Session/Cookie problem with redirect
I think I have solved it now. The application passed an object from a third party library in a GAE session attribute. Sometimes when the object was retrieved from the session attribute it didn't work (often it worked but not always)! Now the application creates a new instance instead of passing it in a session attribute and so far it's working all the time. Something to do with the serialization/deserialization of the object put into the session perhaps, or that using an old instance sometimes failed and that a new instance is needed in this case. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
