I.e., commit and synchronize the project in the old layout, then open the subversion repository view in eclipse and rearrange it there; this avoids typing all those long subversion urls. Then do a subversion update or synchronize; or, even better, just delete the project from eclipse and check it out again from subversion, in eclipse as a new project. The latter is also a good sanity check that you can start from scratch and pull the project down from subversion and do a build.

So its easy to return 2 or 3 values and the Generics offer some kind of type safety. I included a Pair and Triple class in my projects and use them as typed return values.

]]> Kommentar zu First run Maven GAE Plugin von Moritz http://blog.cloudme.org/2010/01/first-run-maven-gae-plugin/comment-page-1/#comment-252 Moritz Fri, 28 May 2010 06:36:15 +0000 http://blog.cloudme.org/?p=77#comment-252 Hi Ludovic, the value of the gae.home property should be the absolute path of your GAE installation on your local machine. You have to put that property either in the USER_HOME/.m2/settings.xml (globally) or in your project's pom.xml. Check out http://www.sonatype.com/books/mvnref-book/reference/resource-filtering.html and http://blog.cloudme.org/2010/04/mavenizing-my-project/ as an example. However, the latest releases of the GAE plugin have a very nice feature, which makes setting the gae.home property obsolete: with gae:unpack you can install GAE in your local Maven repository, no property settings required. Hi Ludovic,

You have to put that property either in the USER_HOME/.m2/settings.xml (globally) or in your project’s pom.xml.

What value do you put? thank you Ludovic Hi Moritz,

That's because I believe that I have a better control about the thumbnail creation process that way and don't need to worry about if a thumbnail was created or not. If I were storing thumbnails only in DB, then I had to handle errors with some custom retry mechanism or a combination of all sort of methods (including the one described in the post). So I decided to go with the simple solution. So far, my application works quite good and there are only few over quota exceptions, so I haven’t looked at task queues yet…

You will have to break the task into smaller chunks. How about generating the thumbs when they are uploaded. The task queue tasks are also killed at 30 seconds.

However, I also like to reduce the number of datastore queries, and decided for memcache instead. I'm using a scheduled task to refresh the cache, but haven't looked at the task queue API yet. There are two problems I'm dealing with when generating thumbnails: (1) The images service gets over quota quite quickly and (2) the scheduled task I've written so far (and which is using a brute-force approach) gets killed after 30 seconds. Maybe a task queue is a better solution. That is another good idea. However, I also like to reduce the number of datastore queries, and decided for memcache instead.

If so, instead, why not store the thumbnails in the GAE data store? You could generate the thumbnails using the GAE task queue.
