Google App Engine for Java — First Impressions

Frank — Wed, 15 Apr 2009 22:52:23 +0000

The news was pointed out to me by a friend before I could blog about it, but Google App Engine supporting Java and servlets is a massive move forward for server side Java.

I’m currently experimenting with my own evaluation of this, but in the meanwhile, here’s Michael Yuan’s take on it.

BigTable and Why it Changes Everything

Frank — Sun, 20 Jul 2008 12:26:25 +0000

I’m still tinkering with Google App Engine, and thus with Python and BigTable. So far I am having trouble getting my head into the solution space provided by the likes of BigTable and memcache. I keep wandering toward solutions where a traditional database seems more appropriate rather than solutions which make use of the advantages of the provided apis. More work needed.

This is a really useful article for what I am doing right now. A selection of Google AppEngine hints and tips from someone who has done a few apps already. I particularly like the reminder about providing static favicon and robots.txt files – something I have bumped into in plenty of other web development situations but had kind of forgot in the excitement of playing with AppEngine.

Google App Engine & eclipse PyDev

Frank — Wed, 25 Jun 2008 09:46:26 +0000

I’ve been looking at Google App Engine recently, and thought I’d have a go at developing something using Eclipse (my main IDE) with the Python development plugin PyDev rather than a motley collection of text editors and scripts.Â Here’s how I got on so far.

I already have Eclipse Europa, so I connected to the PyDev update site I told PyDev where my Python interpreter is located and accepted the default pythonpath entries, then created a new PyDev project and pasted in the example code from the Google App Engine tutorial.

All was going well up to this point, but then I hit a problem. PyDev was showing errors in the code indicating that it could not find the App Engine modules and classes to import.

I looked around the internet and found the following links purporting to help:

Adding in the pythonpath settings from the first one didn’t seem to work. I tried a variety of combinations including creating a new appengine project with the appropriate source folders and referenced it in my new project. Still no luck.

So I created a new project following the steps in the second link, and there were no import problems, even though by default it contains a very simple web application using the App Engine. So I copied and pasted the code from the offending module into the new project and everything seems fine now. I have set up the dev server as a run target in Eclipse and it runs sweetly.

I can only assume that it was the order in which I did things, somehow. Perhaps adding pythonpath entries after code is already present is not picked up correctly by PyDev. Dunno, but I hope this helps someone.
