If you followed part 2 of this tutorial, you have an appengine application that displays a Google map in your browser, and lets you click the map to add markers to it.
While extremely useful on long, cold Winter nights, you probably want more from your application. For example, you’d probably like to be able to save those markers somewhere, so you can share them with your users.…
In this part, I’ll show how to get started with STS (SpringSource Tool Suite) and Spring MVC. We’ll only use the default project that STS generates, but it’s a good start to any development effort with Spring MVC you might get into.…
Google’s appengine is the Google cloud offering. It is highly scalable, and provides a free entry level cloud application platform. However, it is not very trivial to develop for and deploy on.
Google maps API version 3 is the current (June 2011) officially supported version of integrating with Google maps. The API allows you to display and manipulate maps in may ways.…

Coding a login screen is pretty simple in Android, and there’s quite extensive documentation on how to do screen development. However, there’s one neat little trick I wanted to use: the ‘next’ and ‘go’ buttons on the soft keyboard.

Working on a new project, I had a few chats to people and realized that many developers assume that to work with JAXB you need to have an XML schema.

This teknoid blog post describes an excellent method of refining Cake’s default error handling.
Quick reminder: by default, if your debug level is set to 0, cake will always redirect your user to the error404.ctp under app/views/errors).…
Photodropper is an excellent plugin that lets you find creative-commons photos in Flickr and add them to your posts.
On my blog, I use those images only to display at the top left of the post. If you like the way the images look here, you might want to make the following change to the plugin, so that it creates the right code (and not center the photo automatically).…
In a recent Spring webflow project, I had a requirement to generate a PDF on the fly and display it as part of a web page.
The containing web page is part of a Spring webflow, and the PDF generation service already exists.
After some poking around, I came up with the simplest solution ever: Spring MVC……
This one took a while to find out, maybe it’s poor Google-fu or maybe the documentation is just not clear enough – but anyway – Thought I’d write it down in case anyone else spends some hours in the dark over this.…
