The question comes up often. It came up in my new project in November 2011, too. I will use Java EE (JEE, and not J2EE) instead of the Spring framework in this new Enterprise Java project.
I know: Several articles, blogs and forum discussions are available regarding this topic. Why is there a need for one more? Because many blogs talk about older versions of Java EE or because they are not neutral (I hope to be neutral). And because many people still think thank EJBs are heavy! And because the time has changed: It is Java EE 6 time now, J2EE is dead. Finally! Finally, because not only JEE 6 is available, but also several application servers. I do not want to start a flame war (too many exist already), I just want to describe my personal opinion of the JEE vs. Spring „fight“…
The integration framework Apache Camel already supports several important cloud services. This article describes the combination of Apache Camel and the Amazon Web Services (AWS) interfaces of Simple Storage Service (S3), Simple Queue Service (SQS) and Simple Notification Service (SNS). Thus, The concept of Infrastructure as a Service (IaaS) is used to access messaging systems and data storage without any need for configuration.
Spring Roo is a tool to offer rapid application development on the Java platform. It supports two solutions for Cloud Computing at the moment: Google App Engine (GAE) and VMware Cloud Foundry. Both provide the Platform as a Service (PaaS) concept. This article will discuss the Cloud Foundry support of Spring Roo. GAE was discussed in part 1 of this article series (https://www.kai-waehner.de/blog/2011/07/18/rapid-cloud-development-with-spring-roo-%E2%80%93-part-1-google-app-engine-gae).

What IT certification should I do next? This is what I wondered within the last weeks, after I passed the SCJP 6 successfully some months ago. I surfed the internet a lot to find information about possible IT certifications.
I was at the Herbstcampus 2010 in Nuremberg, that is a four-day IT conference. The main topics consist of Java, JEE, .NET, Agile Development and SOA. Although, prominent speakers are missing, many very good and interesting sessions were available. Here you can find more information: Herbstcampus.
In the following, I want to mention some more information about a few of the sessions I visited, and interesting facts that I noted.
Yesterday, I visited the one-day conference “DOAG SIG Java”, because I presented about applicability and limits of Java Server Faces 2.0 (JSF 2.0). The main subject was the Java Enterprise Edition 6 (JEE 6).
The final track included a live demo of Adam Bien, a well-known JEE expert, author and speaker (also involved in the JEE specs). A very nice “live show” of the JEE 6 features!
The participants (including me) asked a lot of questions crititcally, Adam Bien always had very good answers and explanations because of his excessive experiences with Java technologies for several years.
