I now have problem with com.google.appengine.api.datastore.DatastoreNeedIndexException: no matching index found... And, the admin Dashboard shown === Number of Indexes 100% 100%199 of 200 === the application is a relatively simple, yet got such problem. i wonder how many datastore indexes u guys have. pls share it here. p/s: google appengine team, can increase the quota for index ...? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: Disappointment about JPA relationships :(
Hi Matthieu, You are right, you need some conditioning and then you need to work around the limitations of working with relationships around JPA. Then finally you tend to realize more and more that may be you are better off with unowned relationships Here are the issues that we faced and tried to resolve http://wp.me/pNh6u-6b Regards | Vikas www.inphina.com On Oct 23, 9:01 pm, Matthieu Bertin wrote: > Hello, > > I'm just here because i feel i need to rant a little.

[appengine-java] Recurring tasks
Hie Guys Our application manages a list of blood donors. Time to time these blood donors are unreachable so the administrators can mark such blood donors as inactive. However, these blood donors should be active again after 1 day automatically. How should we achieve this? ?In regular J2EE apis we can write scheduler classes to do the same. What is the option in GAE? Are there any limitations? I went through a bit and feel like task queues are the way. But I am not sure? If yes then for above scenario how should it be done?

[appengine-java] Re: Recurring tasks
Hi, I see different purposes for the 2: - cron tasks are the tasks I always want to do for sure - tasks via API are tasks that I schedule programmatically when needed and triggered by event that I can't predict in advance. I see personally 2 other purposes for API tasks: a) when I run a task and it comes close to the 30s limit, I pause it, serialize its context and schedule a task with this context. When the task starts, it's in fact a restart with another 30s credit for running b) I also tasks in context of transactions if I want to be sure that the action of the task is done (i.e datastore writes) even if the transactions fails -> for example, store errors in datastore for later analysis for a failing transaction / program, etc. regards didier On Oct 25, 6:23 am, Vik wrote: > Hie Thanks for the response. > > I am confused a bit.

[appengine-java] Feature Request: Restore prepared query from a cursor
Hi App Engine team, the Cursor stores the full state of a prepared query to check if it matches the query when applied and raise an exception if this is not the case. Now the usual use case is that during a paging operation the cursor is transferred between client (e.g HTML page, JSP, ...) and server. The server restores the cursor from the string encoding and applies it to the PreparedQuery. As the server is stateless the server side needs to restore the prepared query somehow either by caching it somewhere or by reconstructing it from the application context (I take the reconstruction approach) Now I wonder if you could avoid caching/reconstructing the query if you have the cursor, because apparently the cursor contains the full state of the query. Wouldn't it be a trivial change in the API of the SDK to introduce a method on the Cursor class like: PreparedQuery getQuery() Then you could have on the server have code like this: Cursor decodedCursor = Cursor.fromWebSafeString(encodedCursor); PreparedQuery preparedQuery = decodedCursor.getPreparedQuery(); List nextBatch = preparedQuery.asQueryResultList(withLimit(20).cursor(decoded)); Not sure if I missed something but this seems to be trivial and it would give so much convenience...
