My first proper morning of having a look at the Java support for Google App Engine. A tip for anyone who is developing, make sure you have Eclipse and the AppEngine plugins, it works wonders.Coding the app up is no real problem. If you are used to JDO queries then you’ll be fine, I’m so used to JDBC hell that I had to read the docs. Where the plugins really shine is on deployment. It totally removes the whole command line procedure. Click once, enter your username and password and up it goes (fortunately not in smoke). All done and working. Not a design classic but here’s the first app.
