[appengine-java] EL update or CL fix
It's been a while since I reported this odd ClassLoading (and EL) behavior: * http://groups.google.com/group/google-appengine-java/browse_thread/thread/e9c9578f034dd1f9 Any plans on fixing this? Or, are there perhaps valid reasons why EL is included in GAE distribution AND loaded by the app's CL? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Task queue with HTTP POST not working.
I followed the codes in GAE document to make a simple task queue: Queue queue = QueueFactory.getDefaultQueue(); queue.add(TaskOptions.Builder.method(TaskOptions.Method.GET).url(/ security)); This works perfectly.

[appengine-java] AppEngine + Google Data APIs + OAuth
Hello All, I noticed that there is not a lot of material (in fact none) on the web for creating an app in App Engine that uses Google Data APIs and OAuth for Authorization to the APIs. So I started working on a Google Doc to document this process, which now has turned into a Google Site: https://sites.google.com/site/oauthforapi/(still in progress) I am looking for: 1) Suggestions to improve this step-by-step; 2) Few people to review this guide; 3) Direct contributors to add content to the guide. I will add these folks as contributors to the Google Site. Next, I am working on sample code that uses this stack.

[appengine-java] API CRUD interface for application ?
Hello, The application we run is a backend online service and has no GUI. We some how need to be able to upload new content / update existing datastore entity records. The database model is relatively simple: 1 to many relationships on all of the kinds. I would be happy to use learn about a library / some API configuration option to expose an interface so that external code can do the CRUD logic. Is there any support for this in GAE / other library that runs on GAE? If this plays any role in your suggestions: We're super focused on response times so: We currently use low level data store API. I actually tried Objectify but found even it to be an over kill for our needs. I also deleted all the jars the were added by GAE eclipse plugin but are not used by the code. Actually the list of jars used by the application consists of: ls war/WEB-INF/lib/ appengine-api-1.0-sdk-1.3.7.jar appengine-jsr107cache-1.3.7.jar jackson-core-asl-1.6.0.jarjsr107cache-1.1.jar appengine-api-labs-1.3.7.jar EyeViewUtils-1.0.1-SNAPSHOT.jar jackson-mapper-asl-1.6.0.jar log4j-1.2.16.jar Any recommendations / personal experience with this issue / pointers about correct design of the interface / what technology to use and co. are highly welcome and appreciated.

Re: [appengine-java] Re: App Engine and IP Addresses
Exactly. Use https://addons.mozilla.org/en-US/firefox/addon/6647/ to see what headers your browser send as part of the HTTP GET request and emulate them in C code. Should work :).

[appengine-java] Why is guestbook-example-fts (full text search) example working but mine is not?
Hi, I'm really confused about the AppEngine database index limits. My project is using 15 tokens to index some content. I'm using the index then to self-join it up to 3 times. Then my index looks like this: isOnline ▲ , searchIndex ▲ , searchIndex ▲ , searchIndex ▲ , normalizedName ▲ isOnline = boolean searchIndex = list (max 15 items) normalizedName = string Now as soon I add another searchIndex or another property to the indexes I get an error when AppEngine is trying to build the indexes. -- BUT -- Then again I'm looking at the http://code.google.com/p/guestbook-example-appengine-full-text-search/ example which was mentioned by Googles AppEngine Team.

Since you can't create files on the file system, I suspect the approach of
streaming the zip through a ZipOutputStream would be the most plausible one.
That and you set a content-disposition header of myfilename.zip.
And I hope it'll work :-)
