In my previous post I shared an example showing data paging for flex. The most important subfeatures of our ‘managed data paging’ feature are:
Loosely coupled interface – the feature will work without implementing a specific server-side interface and can be used with Java, .NET and PHP
Can be used with ANY Flex data component (applicable to both MX and Spark architectures)
Memory management – our data provider will maintain only specific number of pages in memory and will re-fetch data on as needed basis
We put together another example visualizing how memory management work. The example works with a database table containing 2.6 million records. Any time a page of data is loaded or removed from memory, the visualization component reflects it by drawing or removing a line. You can see the example in action in the video below. The source code and the database script are available at the bottom of the post. Enjoy!
I am very happy to report that we released a new version of WebORB for Java – version 4.3. The theme of the release is ‘Developer Productivity’. As you may already know, WebORB enables integration at four different levels: remoting (RPC), data management, real-time publish/subscribe messaging and video/audio streaming and recording. With this release, we deliver code generators for all of these levels of integration. Below is a brief description of the new features you will find in 4.3:
Data management for JavaScript Clients – If you’re familiar with WebORB, more than likely you know about our data management framework. If not, then you can learn about it either from the WebORB Data Management documentation or the Data Management webinar recording. In short, the framework lets you quickly import your database schema into our Data Modeller tool and generate client and server-side code to enable full CRUD with your data from the ActionScript or JavaScript client or the server-side code. The same code generator can also create a demo application which demonstrates the power of the API. The JavaScript client support lets you create a data-driven ORM solution for your database in seconds. In addition to the APIs for CRUD operations, the JavaScript client also supports client-synchronization for the changes done by other clients working with the same dataset.
Remoting code generator for Robotlegs - Robotlegs is quickly becoming a popular ActionScript framework. We included a very powerful code generator which can generate all the supporting ActionScript classes for a given Java service (POJO, EJB, Spring bean, Grails service or SOAP web service) . The generated code enables remoting with the service and includes all the supporting classes conforming to the Robotlegs framework. This includes controller, events, mediators and ActionScript value objects. Read more about WebORB and Robotlegs integration.
Native Android Java code generator and invocation client - WebORB includes a tiny native Java library supporting remote procedure calls of the WebORB hosted services from native Android Java applications. Additionally, we also added a code generator which can create Java client-side code for any given WebORB service. The generated project also includes a visual invoker to make it easier to see the generated code in action.
Windows Phone invocation client (with code generator)- similar to the native Android Java library, we also added a native Windows Phone (Silverlight) client-side library into the WebORB distribution. Using the library Windows Phone applications can easily integrate with WebORB-hosted Java services using either RPC or publish/subscribe APIs. There is also a code generator which can create C# code and a sample Windows Phone project for any deployed Java service.
New Swiz code generator – We have completely rewritten the Swiz code generator to support the latest release of the Swiz framework. The generated code includes all the events, pre-wired controller, service invoker and value object types.
Code generator for rich media Flex, AIR and Mobile apps – WebORB for Java supports the RTMP protocol and enables video streaming and recording, remote shared objects and server-side data push. In this release we added a code generator which can create a sample Flex, AIR or mobile application with the code demonstrating all of these features. Optionally, the code can be generated to support RTMP tunneling for any of the selected features. Read more..
Code generator for multi-client Publish Subscribe messaging – WebORB provides native libraries and APIs for publish/subscribe messaging for Flex, AIR, JavaScript, native Java and .NET clients. The unifying concept for all of these APIs is the messaging destination. With the new release, it is trivially easy to manage destinations and on top of this, developers can quickly generate native publish/subscribe messaging apps for all the supported client-side types.
Publish/Subscribe Messaging Test Drive – When you develop a messaging application, it may be very important to be able to observe message traffic over your destination. It is very easy to do that with the new release. Simply open the management console, Find your destination under the Messaging Server tab and click “Test Drive”. The feature lets you both create subscribers and publish test messages.
As you can see it is a feature packed release. We also fixed quite a few bugs and you can access a full report in the Midnight Coders bug tracking system. We plan to publish follow-on posts with videos and examples demonstrating all the new functionality in the coming days.
Earlier this week we announced a release of WebORB version 4.4 for .NET. In that blog post I said I’d be posting short videos reviewing the new features and functionality. The first of them, offering an overview of WebORB Data Management for JavaScript, is available. Enjoy!
If you are looking for an alternative to Live Cycle Data Services (LCDS) to do Flex data management, WebORB for Java (Enterprise Edition or Community Edition) is a great alternative. Ken Nelson from San Clemente Technology wrote an excellent tutorial on how to do data management using WebORB, which is posted on the Adobe Developer Connection site. Here is an excerpt from his article:
“In this article I will show you how to build a data driven application in Flex using WebORB for Java. You will learn how to connect WebORB to your database, use WebORB for Java to generate your database access code, and integrate the generated code with your Flex project.”
The complete article with sample code can be viewed here:
We had a great Webinar yesterday morning, entitled “Shave 2+ Weeks Off Your Next Project Schedule with WebORB Data Management .” Seventy people registered, and 31 attended, which is a unusually-high attendance rate (44%). The attendees asked a number of good questions, too.
Not bad for 7am in Silicon Valley!
A lightly-edited screencast of the webinar can be found these YouTube videos:
Our next webinar, How to Brighten Up Your Application With WebORB Media Streaming, will be held December 16 (a week from tomorrow), from 3pm to 4pm Central Standard Time. Register now, because seating is limited!*
Whee!

*Not really. But you should register now, anyway, before you forget.
