Lets start with a small quiz: Can you find 3 differences in the pictures below?
Yeah, you got it. That was an easy one. :)
Surprisingly, implementing preview for extra asset types has been relatively simple as well. When coming up with the architecture of DAM, the Magnolia team chose to not generate previews and thumbnails of assets directly in the module, but rather delegate this functionality...

This is a follow-up to last week's blog in which we introduced the new Client API in JAX-RS 2.0. In that blog, we defined a simple AtmService and showed how to use the Client API to access its resources. For example, the following code was used to check an account's balance:
Client client = ClientFactory.newClient();String bal = client.target("http://.../atm/balance") ...

Have you wanted to do something with asynchronous I/O? I did. After doing some work with Node.js, I wanted to find a way to get some of the goodness of its programming model for Java.
The Acteur project is the result - a framework for building scalable, asynchronous web applications using Netty + Guice - was the result. The programming model is a little unusual - you treat constructors as...

Web Development Tools
As a test, I re-created the HRSystem application as described in the tutorial Developing Rich Web Applications With Oracle ADF. It's more than your basic Hello World application. For starters, the HR system application accesses a database. It also takes advantage of some sophisticated ADF features, such as graphs, page flows, auto-suggest, menu options to export to Excel and display in...

Hey, it's been awhile since I last posted on this blog, largely because I didn't have much to say about Java for awhile, and partly because I've been working with Node.js over the last year. It's a new software platform that I think the Java community needs to know about, and as the author of a book about Node (a.k.a. Node.js) I may be the person to explain a thing or two to y'all. ...

Did you ever tried to visualize dependencies between pages on your average website? If so, you probably know what kind of pain it can be. The relations tend to be messy and any kind of chart displaying them is not easy to read.
The other night I was looking for some charting library and run across MooWheel.
Using the Wheel for rendering the deps you get reasonably readable chart for smaller site...

Somebody shown me the tool called Red Bot the other day. The tool will check the headers of responses sent by your server, the compression of the content during transfer, server clock as well as modification dates claimed by your content. The info it gives about each page of the site is broken in 3 sections - General, Content Negotiation and Caching.
When I saw the tool, I thought it might...

In my last blog post, I explained how to add versioning capability to templates. Being able to create, view and restore different versions of templates is great, but sometimes it's not so easy to see what has actually changed. And we might not be as lucky as having comments about the change from the author, or they might be cryptic to the point of being useless.
So let's try and add the diff and...

In this article from Making Sense of NoSQL, the authors discuss how Bigtable systems store data using row and column keys and how they...

The definition of a Validator according to the Validator interface:
void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException
The Faces Context is passed in so the validator can introspect various aspects of the request and response.
The UI component is passed in because the actual value will be stored in that UI component after it has been...
