End of the last year and beginning of this I've spent trying to get Magnolia work with ModeShape. There were issues with both of the apps. On one end, Magnolia had issues with the Modeshape session data refresh strategy, on the other one, Modeshape was sometimes stricter then JCR spec required it to be when it came to queries. All of those were elementary issues that were relatively easy to...

Meanwhile I am looking back to more than 25 years of programming, and more than a decade I spent in a very sensible area where quality (in the sense of zero failures) plays a big role. So call me "sensible" for quality. For long years "we" (i. e. developers) had hard work to do using simple command lines tools like vi etc., but meanwhile there are great, even free,...

Google maps was a useful hit from the moment it went on line. Since then thousands of web pages have added map capability to their sites, courtesy of Google. Let me illustrate how you can add Google maps to your Java application.
Google furnishes its maps via a simple REST request. Does this mean you need to add some fancy REST framework to your application? Not at all! Java provides...

It seems that when we develop a trait (that includes both abstract and concrete methods) in Scala and compile it, the outcome includes two jave byte code files. The first includes the definition of an interface with an identical name to the one we gave our trait. The abstract methods that interface includes are the same methods defined in our trait. The other file includes the definition of a...

Mark Reinhold announced today that the JDK 7 / JavaSE 7 project has slipped once again: mid-2011 without Jigsaws and Lambdas, late 2012 for JavaSE 8 with those. The delay (or some other bad news like dropping features) was already expected by anyone who tracks the project. But really, how big and bad is this delay?
As a big enthusiast of both Jigsaw and Lambdas - and as a tech writer who just...

In this post I show how simple is to integrate mybatis and spring framework.
The requirements are:
Spring Framwork 3.0.5 + dependencies
Mybatis 3.0.3 + dependencies
CoreJavaBeans1.0.1 + dependencies
First of all, let's define a model bean:

If you have problems installing Gitosis on Windows, I suggest that you read that guide : : Git Repository Server Gitosis on Win7 (100% working), maybe you will be able to find what you missed.
In this guide, I'll describe raw problems that I found with the solution. Before I came with this guide, I try to install Gitosis on 3 computers and 4 Virtualbox installation by follow tutorial that I...

If you are here, it's because you're lost or you have problems installing a git repository server on Windows. I really hope it's for the second reason :) .
I choose the wrote this blog even if I know there are a lot of blogs about this subject, because none of them worked for me. Before I came with this guide, I try to install Gitosis on 3 computers and 4 Virtualbox installation by follow...

I want to let you know that since the release of Caucho Resin 4.0, Atmosphere applications can be deploy on Resin and will be supported natively. Resin 4.0 implements Servlet 3.0.
That's really good. Another web server that is supported.
What about the Websocket's Caucho implementation... nah ! There implementation is too buggy right now. I suppose the code it using a early release of the...

Just a little note that we try to add Websphere native support for Atmosphere. We work really hard to find an API that could allow us to do that, but is simply impossible.
We were able to get in touch with the dev team of Websphere and the dev team of WebSphere Application Server Feature Pack for Web 2.0. They have demo that used bayeux for comet application or JMS to simulate asynchronous...

Just to let you know that Grizzly Deployer was adopted by another framework : Atmosphere.
Since Atmosphere-0.6, Grizzly Deployer is in the module : spade-server
To launch Atmosphere application you could use Grizzly Deployer or use Atmosphere-Spade-Server (that used Grizzly Deployer under the hood).
You can browse the changes on github : http://github.com/Atmosphere/atmosphere/tree/master/...

It has been a while since a blog about Grizzly, I was too busy adding new features. The Grizzly Deployer's community grows and requested theses new features.
Here a quick list of the changes :
Can starts without applications to deploy
Can be embedded and extended easily
and few bug fixes (thanks to the community)
A little overview or remainder of what is...

I feel a bit guilty saying bad things about Apache Ant. It's free, it's available everywhere, and a lot of volunteers have put a lot of work into making it what it is. You can very quickly and easily make a build file for simple Java projects. But. It seems to have been more accreted than designed, and if you try to use the core system to accomplish...

I want to share a problem that we had in our project. We were doing a real-time "Profits and Loss" server (P&L). The server sends stock updates to all the users subscribed to the stocks, basically as Google Finance or Yahoo Finance.
I will used a basic approach (no aggregation and no optimization) to explain the problem that we had with Serialization and...
