We have used Spring Roo in a web project and show how we generated an early prototype and transistioned to early development and then to production code.
Is Ehcache a NoSQL store? No, I would not characterise it as that, but I have seen it used for some NoSQL use cases. In these situations it compared very well — with higher performance and more flexible consistency than the well-known NoSQL stores. Let me explain.
The point of "Graham Hacking Scala" is to share with you my knowledge of and experience with the Scala programming language. The blog will contain everything from introductions to basic features through to in-depth analysis of complex techniques and problems. When I make mistakes, you will learn from my mistakes. When I discover cool features, you will learn about them, too.
EJBs in Scala schreiben
Was spricht eigentlich dagegen, eine EJB in Scala zu implementieren? Um diese Frage zu beantworten, habe ich ein Demo-Projekt aufgesetzt, in dem ich zwei EJBs in Scala implementiere.
1.1. Docbook and maven
I was looking for a maven plugin that produces documentation with syntax highlighting from docbook .
1.2. For the impatient
This article has been written in docbook , and generated via maven with the docbkx maven plugin .
You can check it out

You can download a ready-to-build maven project here http://www.springfuse.com/blog/docbook/docbook-1.0.0-src.zip . It is ready to be customized for your needs.
InfoQ has gathered a virtual panel of Enterprise Architects who have lived and implemented SOA for most of this decade to better understand what SOA means to IT in 2009.
Looking at recent articles and various BPM solutions, it would be easy to assume that BPEL is now the defacto standard to be used when implementing a workflow engine. From a technical perspective this may well be correct, however few people will claim that BPEL can be easily understood by the end-user, a.k.a the business analyst, who definitely prefers a graph based notation such as BPMN.
Reexamining the Limitations, Expectations, Capabilities and Misunderstandings of BPEL, as well as Executing BPMN Directly It seems that conventional wisdom has been for a while that "Business Process Execution Language" or "WS-BPEL4WS" is the standard for execution in the BPM space. At the same time, the majority of BPM and workflow products on the market today work successfully without using BPEL.
WSRP is an open standard proposed by OASIS for several years. The spec now is sponsored by a number of
big names like IBM and BEA. There are currently two active implementation of the spec. One is wsrp4j from
Apache foundation (still a incubator project, been developed since 2002). The other one is a subproject of
dev.java.net Open-Portal.
I have been exposed and done lot of development on the Apache's wsrp4j project. Thus, in this guide I will
mainly discuss wsrp4j implementation.
At this point, wsrp4j project is still under heavy development and re-construction. It is almost impossible
to get the trunk snapshot in the project repository and make it work without pulling all your hair out to figure
out how to set it up properly. This mostly caused by the lack of documentation and support from its developers.
Still, there is a stable (enough) revision which we can use to make a perfect wsrp4j environment.
The wsrp4j revison I use here is 440430 along with pluto portal 1.0.1 release for setting up a producer.
Jetspeed 2.1 (latest version currently) will be used as a container for wsrp4j consumer (wsrp4j-proxyportlet).
Of course, you can use pluto to setup wsrp4j consumer as well. But that is very easy to do.
Plus, pluto portal doesn't provide a lot of bell and whistle in the GUI side as Jetspeed portal does.
The first part of the visual git tutorial explains how to locally track project files with the git version control system. It shows how to add and commit changes, how to browse the history, revert changes and how to work with tags and branches.
