During this week’s Oracle OpenWorld Conference, we were given some sneak peeks into the short term future of the Oracle SOA Suite. During various roadmap sessions, on the demo grounds as well as in the keynote session by Thomas Kurian (the replay of which you can see here: http://medianetwork.oracle.com/video/player/2687033686001), new features were described and demonstrated, allowing us to get a fairly good overview of what is going to come for SOA Suite – later in 2013 and sometime in 2014 (probably the first half of that year).
The SOA Suite plays an important part in the three themes Thomas Kurian set down for the Fusion Middleware suite of products: support for mobility, cloud and business user empowerment.
Some of the highlighted new aspects of Oracle SOA Suite are:
- Adapters to connect from on-premise to in-the-cloud – specifically targeting SalesForce, RightNow and also providing an SDK to create custom integrations into the cloud (the first cloud adapters will be released on 11g, before the end of the year)
- Mobile enablement by exposing RESTful services that communicate using JSON as well as adding the capability to call out to such services (12c functionality)
- Enhanced More >
Dit is de zomer van de 12c-lanceringen. Na de database zijn sinds vorige week Oracle ADF 12c, Oracle JDeveloper 12c, en Oracle WebLogic 12c beschikbaar. Met zoveel nieuwe mogelijkheden dat AMIS op 14 augustus een gratis seminar organiseert waarin we de nieuwe versies introduceren, becommentariëren en vooral ook demonstreren.
Maar liefst tien specialisten verzorgen presentaties: Steven Davelaar van het A-Team van Oracle en Aino Andriessen , Betty van Dongen, Edwin Biemond, Jonathan Damen, Luc Bors, Lucas Jellema, Marcel Oldenkamp, Niels Gorter en Paul Swiggers van AMIS.
De onderwerpen die in het programma aan bod komen zijn:
- Oracle JDeveloper 12c – de vernieuwde IDE
- Software engineering met Maven, Git e.a.
- Oracle WebLogic 12c
- REST-services en JSON support
- ADF Faces – nieuwe en verbeterde componenten
- Implementatie van UI patterns met Oracle ADF 12c
Vanaf 16:30 bent u van harte welkom. Om 17:00 start het seminar. Tussendoor komt ook de beroemde AMIS frietkar nog langs. Reken op veel demonstraties, uitleg en levendige discussies.
We hebben ruimte voor 80 mensen. Bij overschrijving openen we een wachtlijst. Schrijf je daarom hier snel in.
The attraction of APEX has increased tremendously with the recent launch of the Oracle Cloud. APEX already supported departmental development and deployment of business applications with minimal involvement from the IT department (only a database needed be made available). Positioned as the ideal replacement for MS Access, APEX probably has managed better to capture the eye of developers and was used for enterprise application development at least as much as for the kind of tactical applications that Oracle strategically positioned it for.
With APEX as PaaS & DevaaS from the Oracle Cloud, a leap is made to a much higher level of business value. Now the IT department is not even needed to make infrastructure available with a database running on it. All the business needs is a credit card. And the business application that is developed, managed and used from the cloud through a standard browser can now just as easily be accessed by users from around the world as by users from the business department itself. As a bonus – the development of the APEX application is also done in the cloud – with no special demands on the location or the enterprise access privileges of the More >
Create simple Java application to post JSON message to CometD Bayeux Channel using Apache HttpClient and Maven style NetBeans project0
The objective discussed in this article is to post messages to a CometD Bayeux Channel with a standalone Java Class – without dependencies on CometD. For example to control from Java the Slideshow introduced in the synchronized Slideshow demo application created using CometD (see previous articles Push based synchronized Slideshow demo application implemented using CometD and jQuery running on Tomcat and Publishing to CometD Bayeux Channel from inside the Oracle Database â€“ PL/SQL based push to CometD Web Client ).
This article describes the creation of a simple Java Class leveraging Apache HttpClient to post HTTP requests (JSON messages) to a CometD Bayeux Channel. The main point is to show working code with the lest dependencies, not an optimal program (it is far from optimal). The article demonstrates how NetBeans and Maven conspire here to make the task as simple as possible. The Maven support in NetBeans allows me to simply create a new Maven style project of (arche)type Java Application.
Push-based synchronized slideshow web application – implemented using WebSockets and Kaazing WebSocket Gateway9
In the last few articles, I have discussed downloading, installing and running demos for a number of different tools, frameworks and libraries that support push-style (web) applications in one way or another. I have looked into ‘classic’ comet with Grizzly, Atmosphere and CometD as well as ADF Active Data Service and WebLogic Pub/Sub (Bayeux) Channels. I have also looked to WebSockets with jWebSocket, again Atmosphere and CometD and also with Kaazing. I intend to now take a closer look at some of these frameworks, by taking a simple push-style application and implementing it using each of these frameworks. The functionality I will be implementing is simple:
- the selection of the image is communicated to the server (background WebSocket based or alternatively regular AJAX)Comet (Bayeux)/Long Poll style)
- the server informs all connected clients about the selected image through a pushed message (background WebSocket based or alternatively Comet (Bayeux)/Long Poll style); these clients all synchronize that slide selection
- a Java (server side) component can also connect to the More >
