[appengine-java] Empty LinkedList won't overwrite non-empty LinkedList in datastore ...
Hi, My Data class has a field of type LikedListKey. If there is only one Key in the list and if I delete it, the deleted Key will not be deleted from the datastore (after persisting the entity).

Re: [appengine-java] Why use servlets?
JSP's get converted to servlets before execution, so when your using JSP's you're using servlets. Many people, myself included, use servlets for the business logic and use JSP's for the presentation (generating the html). So, in my servlets and filters I'll determine if the user is logged in, has permissions to view whatever page they are attempting to view, query the datastore or memcache for what the data they want to view, etc. Then, I'll forward the data to the JSP page to generate the HTML view. There's nothing that stops you from using JSPs for everything, but most programmers prefer doing the heavy coding stuff in servlets and use the JSP for what they do best which is generating HTML.

This is the first time I've announced this opensource project in this forum because until now there wasn't anything GAE-specific about it.

This is *the* fastest way to pull down significant quantities of data from Facebook. http://batchfb.googlecode.com/ Here is a quick snippet of code: --- Batcher batcher = new FacebookBatcher(accessToken); LaterUser me = batcher.graph(me, User.class); LaterUser mark = batcher.graph(markzuckerberg, User.class); LaterListUser myFriends = batcher.query( SELECT uid, first_name, pic_square FROM user WHERE uid IN + (SELECT uid2 FROM friend WHERE uid1 = + myId + ), User.class); LaterUser bob = batcher.queryFirst(SELECT timezone FROM user WHERE uid = + bobsId, User.class); PagedLaterPost feed = batcher.paged(me/feed, Post.class); // No calls to Facebook have been made yet. The following get() will execute the // whole batch as a single Facebook call. String timezone = bob.get().timezone; --- You can stack up hundreds of Graph and FQL requests using the Future?-like interface; BatchFB will group them into batches and execute the batches in parallel on App Engine.
