Wire Hibernate Transactions in Spring
by Binildas Christudas
05/18/2005
This article is intended to show how Spring can be used to assemble components, including their transaction contexts. Connecting to a single data store from within a J2EE application is not a big hurdle. But when it comes to assembly and integration of enterprise-class components, the scenario gets complicated.

Implementing Transaction Suspension in Spring
by Juergen Hoeller
07/04/2005
The Spring Framework, a popular Java/J2EE application framework built on a lightweight Inversion-of-Control container, is particularly well-known for its data access and transaction management capabilities. Spring's declarative transaction demarcation can be applied to any POJO target object, with the full sophistication of declarative transactions as found in EJB Container-Managed Transactions (CMT). The choices for a back-end transaction manager range from simple JDBC-based transactions to full-fledged J2EE transactions via JTA.

Europe Shows Its Stuff: Innovate 2006
Michael Arrington
Dozens of (mostly) European companies showcased their new consumer web applications at Innovate 2006 in Zaragoza, Spain this week. As usual with conferences like these, the companies were young, rough and hungry. And I see a lot of potential with at least a few of them. I’ve summarized my favorites below and look forward to profiling these individually.

There have been big changes in the online video space since I wrote a comparison post of the companies in the space (Flickrs of Video) last November.
Some things haven’t changed: Flickr still hasn’t released a video product, and YouTube (TechCrunch posts here) is still the reigning champ of online video with just massive traffic growth and mindshare.
But new tools are coming out to make sharing videos online even easier.

Round-up of 50 AJAX Toolkits and Frameworks
The following is a compilation of all of the AJAX toolkits and frameworks that I have either reviewed or have first hand experience with and would recommend. It seem like a new AJAX toolkit or framework has come out every week or so since the term AJAX was coined a little over a year ago. As a designer and developer I find these tools invaluable in the process of rapid web development.

Google Web Toolkit (GWT) is a Java software development framework that makes writing AJAX applications like Google Maps and Gmail easy for developers who don't speak browser quirks as a second language. Writing dynamic web applications today is a tedious and error-prone process; you spend 90% of your time working around subtle incompatabilities between web browsers and platforms, and JavaScript's lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.

OK if this does what it says on the tin (aka: In production, your code is compiled to JavaScript, but at development time it runs in the Java virtual machine. That means when your code performs an action like handling a mouse event, you get full-featured Java debugging, with exceptions and the advanced debugging features of IDEs like Eclipse).

The Java Persistence API
- A Simpler Programming Model for Entity Persistence
By Rahul Biswas and Ed Ort,
May 2006
The major theme of version 5 of the Java Platform, Enterprise Edition (Java EE, formerly referred to as J2EE) is ease of development. Changes throughout the platform make the development of enterprise Java technology applications much easier, with far less coding. Significantly, these simplifications have not changed the platform's power: The Java EE 5 platform maintains all the functional richness of the previous version, J2EE 1.4.

Data Access using O/R Mappers
12.1. Introduction
Spring provides integration with Hibernate, JDO, Oracle TopLink, Apache OJB and iBATIS SQL Maps: in terms of resource management, DAO implementation support, and transaction strategies. For example for Hibernate, there is first-class support with lots of IoC convenience features, addressing many typical Hibernate integration issues. All of these support packages for O/R mappers comply with Spring's generic transaction and DAO exception hierarchies. There are usually two integration styles: either using Spring's DAO 'templates' or coding DAOs against plain Hibernate/JDO/TopLink/etc APIs. In both cases, DAOs can be configured through Dependency Injection and participate in Spring's resource and transaction management.

Learning to like early aborts
I am a big fan of single return point functions.There are several advantages to this approach:
However, I started questioning this habit in a particular case: when the failure in a condition should cause the method to abort right away.
- Clearer flow of execution. You know the final return result will be run, no matter what.
- Easier to debug. I can set a breakpoint on the return and inspect the returned value.

Clustering at the JVM Level to Maintain Business Logic Integrity
The typical three-tier architecture keeps the code Java developers need for clustering inside the business logic, making clustering a real chore.
Clustering at the JVM level makes Java applications easier to write and cheaper to run.
by Ari ZilkaApril 14, 2006
The way a typical three-tier architecture separates the concerns of data-management logic, business logic, and presentation logic makes clustering, the practice of deploying a single application on multiple machines, a laborious and expensive task for Java developers. (See Sidebar 1. The Typical Three-Tier Architecture.) With the separation structured the way it currently is, business logic currently includes the code required for clustering. Without a clustering plug-in at runtime, developers are left to cluster their own business logic, the frameworks they use, and in some cases, the container in which it all runs.

Discover Seam and Sew Up Your Java Projects Faster than Ever
In the tradition of Spring, JBoss offers Seam, which uses a declarative state model, extensive use of annotations, and two-way dependency injection to make automation of huge portions of your complex Java EE apps not just possible, but downright sensible.
by Mark Smith
April 24, 2006
Recently, a friend called to tell me about a huge turnout at an Atlanta JUG meeting to hear about a new product from JBoss called Seam. I went to my keyboard and after just 20 minutes of reading about Seam, I was very impressed. For starters, Seam is based on the lightweight standards in Java EE 5 (J2EE 3) like the new entity bean spec, JSF, annotations, interceptors, and session beans. Like Spring, Seam uses inversion of control but unlike Spring, Seam allows injection of stateful objects. Much of the data movement and framework/API manipulation work that enterprise Java developers have drudged through for 7 years disappears with Seam.

It sounds too good to be true: free word processor, spreadsheet, and presentation programs that are compatible with their Microsoft Office counterparts and that work in a browser.That's the promise of ThinkFree, a Web service that offers all this, and more.

Sphere Blog Search
Wednesday May 03rd 2006, 10:11 pm
Sphere, a new blog search engine has launched a couple days ago, along with $3.75 million in capital and has been quite the buzz the last few days. I have seen both good and bad commentary about Sphere so far and I too have mixed feelings about it so far. I’ve actually been beta testing Sphere for the last few months and immediately fell in love with it then, although felt it lacked some key features that Technorati has with statistics and related media. By time of the official launch of Sphere, I was happy to see that Sphere has definitely upped the functionality now including a great custom date range tool, related media searching, and a neat Featured Blog’s area for search results. TechCrunch has provided a detailed overview of features and feel that he’s covered the details for the most part. Because of this, I’m going to give a brief overview of its offerings as well as some details about my experience with relevance, speed, profiles, and statistics.

Using GigaSpaces Grid based Distributed Caching
Overview
GigaSpaces Grid based distributed caching is a major component within the GigaSpaces Enterprise Application Grid-based (EAG) architecture.
It enables applications to reduce the access time to information that resides in the database by bringing the information to the local application memory.
The information is loaded to the cache from the database in an on-demand basis. The cache manages the local memory utilization and the consistency of that information.

XFire: The easy and simple way to develop Web services
Expose your POJO methods as Web services
Summary
Ask .Net developers how tough it is to develop Web services. Amused by your question, they'll probably reply that the steps require less than a minute of your time. Ask a Java developer, and, chances are, you'll get a completely different answer. Five years have passed since Web services was introduced in Java. Yet it is still considered one of the newer technologies, a major reason being Web services are difficult to implement in Java. Now with the release of XFire, a new-generation Web services engine, that situation could change dramatically. Using XFire, you can expose your Java class methods as Web services without writing additional code. In this article, you'll see how XFire makes Web services development easy and simple.

DiscussionAnd the wires were all a buzz about Rails...
Much like a few other java folks, such as Bruce Tate and David Geary, I have been taking a look at a new web framework Rails. Of particular interest to me is its ORM (Object Relational Mapping) tool, ActiveRecord. Since choosing a technology always involves opportunity costs of some kind, I have written this article to compare and contrast with another popular ORM tool, Hibernate. It summarizes what I've learned about Rails, mainly by stacking it up against Hibernate, a technology I'm very familiar with.
