Dear Java/JEE developer – why should you care about ADF?
1Whether you are deciding on the framework to use for your next Java web or mobile project or whether you are contemplating your next career step as a Java EE developer, ADF should be on your short list for consideration. With a new free version, deployment on many application servers including Tomcat, JBoss and GlassFish, extended support in both Eclipse and JDeveloper, and a Java based mobile solution for both iOS and Android – ADF has a lot to offer.
ADF is the Java EE Application Development Framework from Oracle. ADF allows developers to develop rich, enterprise grade Java web and mobile applications in a very productive manner. Many of the generic (plumbing) concerns that need to be addressed for most Java/JEE applications are taken care of by the framework – allowing developers to focus on the business specific functional areas. The initial 80% of the application is created through largely declarative development – 4GL style. The remaining 80% is dealt with in a fairly ordinary coding style, similar to plain Java EE development or to development using other frameworks.
This article discusses the question why any Java/JEE developer should know and care about ADF. It will More >
SMTP: Spring Mail To Program
0All Java developers know, or should know, the Spring framework contains a lot of gems. Recently I discovered a new gem: an easy way to send an email. With the use of one single POJO mail class, you can easily let your application send an email and wire/inject al the mail configuration with the Spring applicationContext.xml. (more…)
Configure JDeveloper 11g to work with Spring 2.5 and AOP
1In a recent article I described the interaction between JavaServer Faces (1.2) and Spring Framework (2.5.x): http://technology.amis.nl/blog/6655/spring-a-surprise-on-a-jsf-developer-how-spring-beans-can-become-jsf-managed-beans. I created a JDeveloper 11g web application that I ran on the integrated WebLogic Server 11g (10..3.2). In this article I will explain the configuration steps I had to go through for making JDeveloper and WebLogic run my simple JSF/Spring application.
1. Create a new generic JDeveloper application; set the project name and add the JSF library
2. Install the JDeveloper Spring extension through the Check for Updates facility under Help in the main menu
Spring a surprise on a JSF developer – how Spring beans can become "JSF Managed Beans"
2Recently I was looking at a JavaServer Faces application, that did something relatively simple – but was exhibiting strange behavior. The output shown on the page (and this is a simplified version of the real life situation) was:
dlroWolleHI had been asked to look into the situation and correct it. Before starting to make any changes I decided to familiarize myself with the application as it currently was. And then they almost tricked me.
The JSF page had a simple outputText component with an EL Expression in its value attribute. Something like:
<h:outputText value="#{someBean.property}"/>I decided to take a look at the code for that bean, to understand the logic behind deriving the value of the outputText. So I first opened the faces-config.xml file to find the managed bean declaration that would tell me which class definition was behind the bean included in the EL expression. However, the faces-config.xml did not contain any managed bean definitions at all. None. And yes, I tried to see whether the web.xml specified any other faces-config.xml alternatives. But it did not.
Slowly it dawned on me (more…)
Project Experience with Acegi Security, Spring MVC and Oracle MapViewer
For a customer with an interesting business we had to build a web application that has a RIA front end, displays data on maps, authenticates thru a web service that is connected with a back office customer subscription system, and that can handle any kind of data (for example shops, garages or whatever) as long as it conforms to a certain format. Depending on the specific dataset the application is configured in a different way and behaves differently. I call it a meta data driven application.
Anyway, taken all these aspects together, the building process has been an exciting adventure. From all frameworks we took the latest versions, and came up with the following tech stack: Spring 2.0, Acegi Security System 1.0, Dojo Javascript toolkit, Oracle (Ajax based) MapViewer 10.1.3.1 (released a month ago!) and Oracle 10g database. Spring formed the ecosystem for our application in which we plugged the Javascript presentation layer at the front end, and the unbreakable Oracle database at the back end. In the same container the Oracle MapViewer application is running. Ajax calls are made from the main application to mapViewer server in order to manage map standard behavior like panning More >
Spring 2.0 in Oracle JDeveloper
On Oracle OTN Shay Shmeltzer has written an article that explains how to use the Spring framework within JDeveloper and how to best setup JDeveloper for Spring 2.0. Interface21 has announced that the final release of Spring 2.0 is planned onSeptember 26th, 2006.

Shay will show “(…) some of the nice features that JDeveloper provides for Spring developers out of the box.” Getting exited?
