Book review: JDeveloper 11g Handbook: A Guide to Fusion Web Development
Jul 21st
In this blog I will share with you my experiences with the Oracle JDeveloper11g Handbook – A Guide to Oracle Fusion Web Development (McGraw-Hill, 2010) – written by Duncan Mills, Peter Koletzke and Avrom Roy-Faderman. It is the successor of their previous book, JDeveloper 10g for Forms & PL/SQL Developers. This is a book to learn the basics of ADF Fusion development and a valuable guide for reference. If you’re a starter, than the hands-on part in this book is a good and practical exercise.
How to call a webservice directly from Java (without webservice library)
Jun 29th
In this blog I will show you how you can call a webservice programmatically in Java without using a webservice library like JAX-WS or Apache Axis. Normally you would use of course a webservice library, but in some cases this can be useful and quick; for example when you have problems generating a client proxy with a webservice library or if you only need some small specific parts of the SOAP response XML tree. It shows that a SOAP call is just XML over HTTP, from a plain piece of Java code. Then, I will show you an example how you can use this and make your own servlet webservice-tester like a simple SoapUI in JDeveloper 11.1.1.3.
ADF 11g R2 : ADF Business Components UI Categories and Dynamic Forms (and some new IDE features)
Jun 7th
ADF 11gR2 has some very nice UI Hints features. Some were already available in previous releases. In this post I will describe the effect of the UI Categories. On the go, I will also point out some other new features. To see how this works, I created simple ADF Business Components from tables (That is, only the employees table from the HR schema).

ADF 11g R2 : Skin Editor First Impressions
Jun 7th
With JDeveloper 11gR2 the skineditor is finally there. I share my first impressions in this post. When you need a skin for your application in previous versions, some configuration was needed. With 11gR2 it is much easier. Read the rest of this entry »
How to remove unwanted SOAP header elements in JAX-WS
May 16th
In our current webservice project with JAX-WS in JDeveloper 11.1.1.3 we have a challenge with calling a webservice. This webservice from a remote organisation does not accept specific SOAP header elements our client application creates – although we followed the contract of the WSDL correctly. Of course this webservice must follow it as well as we have to, but for now we don’t have a choice but to make a workaround. How can we remove unwanted elements from a SOAP header? In this blog I will show you how you can do that using a JAX-WS SOAPHandler that inspects the SOAP header and removes specific addressing elements. Read the rest of this entry »
ADF 11g : Drag’n Drop and Contextual Events
Dec 28th
While going through my list of requirements for our AMIS re-usable ADF taskflow library, I ran into the following requirement: publish a contextual event on a Drag and Drop action. If you know contextual events, you immediately notice that there is no way to publish a contextual event from a Drag and Drop action. There are two types of events: ADF Binding Type events or JSF Component Type Events such as actionEvents, valueChangeEvents or clickEvents (also called eventBindings). However none of those is directly related to Drag and Drop. With some knowledge of the ADF Framework you will be able to create contextual events anyway. This post describes how to publish contextual events when a Drag and Drop action occurs. Read the rest of this entry »

Oracle Fusion Developer Guide: Building Rich Internet Applications With Oracle ADF Business Components And Oracle ADF Faces
In December 2009 some 750 pages of ADF examples and ADF how-to’s were released in a great book: “Oracle Fusion Developer Guide: Building Rich Internet Applications With Oracle ADF Business Components And Oracle ADF Faces” by Frank Nimphius and Lynn Munsinger.
I ordered the book at amazon (this is the direct link) and received it by mail a few weeks later. In this post I share my first impressions with you. Read the rest of this entry »
Configure JDeveloper 11g to work with Spring 2.5 and AOP
Dec 12th
In 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
JDeveloper 11g PS 1 has been released – cool stuff!
Nov 14th
Last month during Oracle Open World I wrote an article on the upcoming features of PatchSet 1 for JDeveloper 11g: . Now this release has been published and is delivering on those promises. For an overview of all (?) new features, take a look at What's New. It is a fairly dry, emotionless, factual list of features small, large and enormous new features. With brief descriptions and screen shots for many of them, it gives you a quick overview of what might be useful to you. Note however that some gems are hidden away in this list for which the meaning and importance is not fully captured I believe in this summary. And of course the relevance of any new feature depends on your specific situation.
Create XSD from XML instance document – new JDeveloper 11gR1 feature
Oct 5th
While looking into the XML functionality in JDeveloper 11g, I came across a feature that was added in the 11.1.1.1.0 release – July 2009: [Create] XML Schema from XML Document. Functionality previously found in commercial products such as XMLSpy, that enables us to make a head start with the development of XML Schema Definitions by using an existing XML Document as starting point.
In this article, I will very briefly demonstrate what this functionality allows us to do. And what its current limitations are.
In short: we can indicate an XML document and have an XSD created that derives its element, type and attribute definitions from the actual XML content in that document. Most XML documents do not represent the entire set of restrictions and freedom that the XSD will describe, so the generated XSD is only a starting point – but a very useful one all the same.
At this moment, the XML source document has to exist on the file system (we cannot feed the tool with a URL). The created XSD document does not work well with multiple namespaces – as well will see in this example. The tool does not create named (complexTypes) – only (nested) elements. It does create, when so requested, simpleTypes with enumerations that describe all occurring values in the source XML document. Such enumerations are usually required only for a limited number of elements. Of course removing the types we do not need is not a lot of work. Yet it would be comfortable to specify in more detail for which elements to create these enumerations.
