In my opinion the Play Framework is the most exciting framework to develop web applications using Java. I recently received a copy of the Play Framework Cookbook by Packt Publications I am looking forward in working my way through it. I think Play's online documentation is pretty good although it probably is not as comprehensive as one would like it to be. It is this reason why I am very glad

I am testing an existing application that relies heavily on JMS message processing. For development I wanted to test outside of the container instead of running a server and deploying to it every time I made a change . After a quick search in Google I stumbled upon the JNDI Support reference page for Apache ActiveMQ. I have heard of it before but I have never used it.   "ActiveMQ will work with

Even though this has been around for some time I have only recently used it and think it is quite nice and worth blogging about. The use case is pretty straight forward, you have a string of data and you want to extract values out of the string based on a pattern. An example would be a date “16-Jun-2010” and you want to extract the day, month and year. Another example could be an email address

In learning more about what Scala can do I decided to work on the problems listed in the Project Euler website. "Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be

Introduction A while back I created four simple Java applications demonstrating Spring's transaction management implementation and recently thought it would be nice to share them. They may be too simple for most people but for someone new to Spring they may actually be helpful. If you want to learn about transaction management in Spring then a good place to start is the Spring documentation and

Introduction In my previous blog entry I wrote about adding security to the shopping cart web application. Part of the change I made to the application was adding a form to register users and a form to add and update items. It made sense to add validation to the fields so that we could maintain the integrity of our data. I currently maintain two different versions of the application:

Introduction Those of you who are familiar with the shopping cart application tutorial will be pleased to know I have finally added security to it. It was never my intention to add security to the shopping cart application as I felt it was a little out of the scope of what I was trying to achieve. However the application would never been complete unless security was added to it. I currently

 Shopping Cart Application – Play Framework I recently spent time stepping through the yabe (yet another blog engine) tutorial for the Play Framework. "The Play framework makes it easier to build Web applications with Java" What is Play? Play is a full stack open source web framework for Java that focuses on developer productivity. "The Play framework compiles your Java sources directly and

I recently received a response from someone who was stepping through my Shopping Cart Web Application tutorial and who wanted to deploy the application on GlassFish and use TopLink Essentials (EclipseLink) as the reference implementation for JPA as opposed to Hibernate. Thankfully there wasn't that much change that needed to be made to the existing ShoppingCartHibJpaPart7 application. This

My previous blog I outlined the steps required to configure JMS resources for WebSphere Application Server 7.0. In that blog I promised to put together a sample application that can be installed to WebSphere Application Server and demonstrates three different implementations of sending JMS messages to a queue and retrieving the messages from a queue. The sample application is an Eclipse project

I was recently given a task to migrate an enterprise application that was running on SAP NetWeaver across to WebSphere application server. The application had a few session beans as well as a few message-driven beans. It used JMS to publish messages to a number of queues. This blog entry outlines the steps I took to configure the JMS queues and connection factories on WebSphere. It is pretty

A couple of months ago I was given a task at work that required code to be written in Scala. At first I wasn't so thrilled about the fact that I would be learning a new language but I must say after spending some time with it I am glad I did. The hardest part in learning Scala was the "getting started" part. The syntax of the Scala code is very different from Java and it required me to "

Seam is ANOTHER web application framework. SIGH. Ok yes sigh another framework to learn but it is not entirely new, if you have been following along with the Shopping Cart tutorials where we used JSF, Facelets, Hibernate, JPA and RichFaces you will see that Seam is not something new just something extra. This is not a tutorial in Seam more like a brief overview, introduction and comparison.

With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.

Introduction Our application has grown in size and complexity since the last time we created our unit test for the shopping service class. This is what I would like to do: Integrate our test case with Spring – this is pretty cool, instead of creating and initializing our objects manually or performing any JNDI looking ups ourselves (that is if we did need to do that) we will let Spring take care

Introduction The Spring Framework provides solutions to many technical challenges faced by Java developers and organizations wanting to create applications based on the Java platform. Because of the size and complexity of the functionality offered, it can be hard to distinguish the major building blocks from which the framework is composed. The Spring Framework can be considered as a collection

If you are new to Hibernate I would suggest reading the documentation on the Hibernate website as well as this tutorial. What you need before we get started I created two separate projects, one that

IntroductionWelcome to the first tutorial I have written in this series of learning how to develop Java web applications. I will be using the same application throughout this series so I thought what better way to kick start this series than to start at the beginning. Before any code is written it is a good idea to understand what is required from us. In this tutorial we are going to define what

I have written a number of tutorials covering a whole range of topics, patterns, technologies and frameworks regarding developing Java web applications. Over the next couple of days and weeks I will be posting these tutorials on my blog. They are primarily intended for junior Java developers who would like a smooth and relatively easy introduction into building web applications. I have

I was looking around to see how to build a JUnit test case using Scala with Spring. I came across this project (currently still in development) called Scalaffinity. You can connect to the SVN repository and download the project. That’s what I did and it has everything I was looking for and more. Thanks to Álvaro Martínez Hernández who put this project together.

So I am learning Scala...why one might ask? I was one of the ones who asked and the answer was quite straight forward and direct: "Do it or you're fired you lazy bum!" I knew nothing about the Scala language up until a few weeks ago and I wasn't over the moon to find out I would have to learn yet another programming language but those words were ringing in the back of my head and it was just
