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.
RESTORE DATABASE Example. MS SQL is a pain, pain, pain.
Hint: Use e.g.
RESTORE FILELISTONLY FROM DISK='C:\MyData.bak'
to get the necessary information.
Here the command from the cited blog entry:
ALTER DATABASE MyData
SET SINGLE_USER WITH
ROLLBACK IMMEDIATE
RESTORE DATABASE MyData
FROM DISK = 'C\:BackupMyData.bak'
WITH MOVE 'MyData_Data' TO 'C:\Data\datafile.mdf',
MOVE 'MyData_Log' TO 'C:\Data\logfile.ldf',
REPLACE
This article show you how you can fix bugs for maven-plugins (eclipse setup for hacking the code, debugging etc.) with a concrete project: maven-eclipse-plugin. Lets start …
Using a rule engine provides a framework that allows a way to externalize business logic in a common place. This will in turn empower business users and subject matter experts of the business to easily change and manage the rules. Coding such rules directly into the application makes application maintenance difficult and expensive because the rules change so often. This article goes into detail on how to architect and build a service that uses Drools to provide business decisions. This service can be part of the overall enterprise SOA infrastructure. As such, it can either be a standalone service that is consumed in a one-to-many model by all contracted consumers, or part of a composite service that provides a complex business functionality. To illustrate this point, the article shows how a service using the Drools rule engine can hide the complexity of automating mortgage underwriting decisions that a mortgage company needs to make on a daily basis.
Sie wollen die Programmiersprache Java lernen? Dann sind Sie hier genau richtig! Im Java Blog Buch werden nach und nach mehr oder weniger aufeinander aufbauende Lektionen veröffentlicht, so dass am Ende eine Art Buch zur Java Programmierung entsteht. Navigieren Sie sich einfach durch das Kapitelverzeichnis auf der linken Seite oder durchstöbern Sie das Inhaltsverzeichnis!
Gerne dürfen Sie auch interessante Themen vorschlagen, über welche wir dann ggf. bloggen werden.
Aber jetzt wünsche ich Ihnen viel Spaß beim Java lernen!

When developing corporate-level business applications (Enterprise Scale) customers often requires implementing support for extensibility of the application object model not modifying the system source code. Use of extensible domain model allows for development of new functionality without additional effort and overheads
Java provides a neat way to carry out long lasting jobs without have to worry about threads and hanging the application. It's called SwingWorker. It's not the latest thing on Earth (released with Java 1.6) and you may have already read about it. What I never came across was a practical example of the swing worker.
