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.
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.
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.
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 …
I have been playing with flex for a couple of weeks now,and i am trying to use flex as the UI and keeping the backend in Java with as usal Spring,Hibernate stack.
So in this series i will create a getting started project(CRUD contact management) using Spring,Hibernate/MySQL,Cairngorm as the UI MVC framework,GraniteDS for remoting and Tomcat as the server . For now i will create an eclipse based project and later move that to maven. The base intention of this project is to setup a prototype with all the above technologies defined and explore all the aspects of GraniteDS features to serve as the POC for other developers if they are willing to try it.
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!
Ps.: Sollten Sie sich dazu berufen fühlen, einen Beitrag zu diesem Werk zu leisten oder gleich als Autor einzusteigen, so nehmen Sie doch einfach Kontakt zu uns auf.
With the addition of generics in Java 5, writing a custom DAO for each domain object is no longer required. There are a wide variety of articles on creating generic DAOs, but my current project uses the approach from this IBM DeveloperWorks article. This approach was choses mainly because of the clearly written article and the integration with Spring. You should be able to extend any generic DAO based on Spring to implement the stored procedure configuration.
Thought I've bookmarked this a long time ago... "With the adoption of Java™ 5 generics, the idea of a generic typesafe Data Access Object (DAO) implementation has become feasible. In this article, system architect Per Mellqvist presents a generic DAO implementation class based on Hibernate. He then shows you how to use Spring AOP introductions to add a typesafe interface to the class for query execution."
Quite an old article on JavaWorld: "As part of the Java language, the java.lang package is implicitly imported into every Java program. This package's pitfalls surface often, affecting most programmers. This month, I'll discuss the traps lurking in the Runtime.exec() method."
