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.
This part of the tutorial will focus on this …
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.
STS is the easiest IDE to use when developing Spring, mainly because it bundles together almost everything you need to get started, and knows where to get the rest.
If you don’t have STS installed, …
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.

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…
All you have to do is define a Web MVC controller to handle pdf requests, like so:
<!– This is

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.
Most of the times, your Spring webflow’s flow will start with a view – you present something to your user, and define transitions to other views in the flow. These transitions are based on the …
Setting up a custom 404 error page serves two purposes:
- It allows you to present your users a nice message rather than the ugly, server-generated default page.
- It serves to mask the server’s identity – so, security is a little better.
The first point is obvious. But the second point may need some clarification – why do we care about the server’s identity?
The reason is – when a potential attacker knows which server your application is …
Seam is quite a good and secure framework as far as frameworks go. However, with a simple ServletFilter, it can be made just a little bit more secure, and maybe help you pass that next audit. In this post you’ll see how to define a Seam servlet filter to secure your website just a little bit more.…
In a recent application, the customer wanted to be able to change session timeout dynamically, without restarting the application.
This being a Seam application, I thought it was going to be quite straight-forward: either add it in the timeout= attribute in pages.xml, or just add it wherever we start a new conversation (conversation timeout is effectively what we were looking for anyway).
But, I was wrong.…
“Setter not found for property class” is one of the most frustrating errors you can get in a Seam / facelets project.
It usually appears late, and you spend a long time trying to solve it. The solution is so simple you have to bang your hand when you finally find it.
I write this in the hope that it shows first in Google searches for this error……
