The functional requirement for my ADF application was fairly simple: the values used for the bind parameters in one ViewObject should be reflected for a second ViewObject. In more functional terms the requirement was the following: when we filter the master records – Employees – by begin year and end year (to only show employees that were hired between the begin and end year) the details – Job History – should also fall within the perioded limited by begin year and end year. The end users complained that when they had set the begin year and/or the end year, they did not like to get job history records that were completely outside that range (even though stricly speaking that is correct).
A similar requirement would be for example when a page shows both orders and complaints for a specific customer and the orders are filtered by date to also have the complaints filtered by that same date.
It is possible to resolve this in the web tier – to retrieve the value of the bind parameters for both ViewObjects from the same bean property. However, when the model based query component is used, the value of the bind parameter is not readily accessible from the web tier.

This step-by-step starter hands-on provides an example how to make a JAX-WS webservice proxy in JDeveloper, and save retrieved data from this webservice in a batch-job to your own database with ADF Business Components. Duration: 60 minutes. For this hands-on example, imagine that your company wants to expand internationally and that reliable, up to date country information is absolutely critical. Recently there were some changes in the number of countries and there might be in the future. Since 1990, 33 new countries have been created. A few months ago the world welcomed a new country (South-Sudan) and yet we donâ€™t know what will happen in Libya (maybe it will be separated in West and East-Libya?). Your company wants to weekly synchronise its internal countries database table with up-to-date country information from a recognised country-monitoring institution that delivers up-to-date country information by a webservice.Part 1 â€“ Create the country webservice client with JAX-WS
We are going to create a webservice client proxy for a country webservice available on: (more…)
Today I had a request to implement a generic logging mechanism for all changes of data (DML) in an ADF application. The log needs to be persisted in a database table. This application uses ADF-Business Components and an Oracle Database. My first idea was to use database triggers for all tables (insert, delete, update for each row) and write the data to a log table. However that was not generic enough because this has to be implemented on every new table. I had to come up with an ADF solution. It’s basic, no rocket science, but useful (more…)
Adding a custom method in an ADF BC Service Interface – update of a single attribute in a selected row3
The article “Quickly creating, deploying and testing a WebService interface for ADF Business Components” (http://technology.amis.nl/blog/9726/quickly-creating-reploying-and-testing-a-webservice-interface-for-adf-business-components) that I recently published describes a way of very rapidly creating the HRService Web Service â€“ an ADF BC driven WebService on top of the EmployeesView ViewObject that exposes the EMPLOYEES table in the HR schema through the Employee EntityObject. However, that article’s true purpose is to show how to create the deployment profile and deploy and test this service, either on the integrated WLS or on a standalone WebLogic Server, in the easiest way possible. This article is an extension of the previous one: it demonstrates how to extend the Service Interface with a custom method (or an operation in terms of WebServices).
As it happens, I required an operation for updating just the salary of an Employee. I will show how I create a custom method in the Application Module’s implementation class, how I added this method to the Client Interface of the Application Module and subsequently to the Service Interface. After redeploying – using the same deployment More >
As you probably already know, ADF Business Components can very easily be exposed through a WebService interface. An Application Module can be configured with a Service Interface, ordinary ViewObjects and custom methods can be exposed in that interface and deployment is relatively straightforward. In minutes, a WebService can be published that exposes operations based on regular ADF BC functionality. This may well give us the fastest way to provide data services on top of a relational database. Several excellent articles have been published on the ADF BC service interface, for example by Steve Muench and Andrejus Baranovskis.
The blog-article you are reading is created as the result of my research and investigations around an article I hope to publish in Oracle Magazine later in 2011. It is adamant for this article that readers can get the example to work with the smallest number of instructions possible – both to make their life easy and to save on words. The article describes a BPM process that interacts with the HR schema of an Oracle RDBMS as one of its activities. The focus in the article will be on BPM, not on exposing data services for the HR schema. The WebService should More >
Ga hier naar onze actuele Â Oracle ADF 11g training.
In oktober kwam na bijna twee jaar van aankondigingen en previews de productieversie van JDeveloper en ADF 11g. Nu, op 20 april, vindt de premiÃ¨re plaats van de ADF 11g training die AMIS in nauwe samenwerking met SAGE Computing Services, AustraliÃ« (van ondermeer Oracle ACEÂ Director Chris Muir) heeft ontwikkeld – op basis van een half jaar praktijkervaring volgend op anderhalf jaar aan experimenteren, onderzoeken en publiceren.
De training is gericht op ontwikkelaars die in de praktijk aan de slag willen gaan met ADF 11g. Wil je meer weten over deze training, ga dan naar 5-daagse ADFÂ 11g Training.
Ben je al ervaren met ADF 10g maar wil je wel graag met ADF 11g aan de slag? Dan kan je ook naar onze Masterclass ADFÂ 11g Upgrade komen waarin we in Ã©Ã©n dag de nieuwe thema’s, functies en manier van werken met ADF 11g bespreken, in vergelijking tot de 10g release. Deze Masterclass vindt voor het eerst plaats op 14 april, in Nieuwegein en 18 mei, in Parijs (in samenwerking met Oracle University). Zie Masterclass ADF 11g Upgrade voor meer details.
