Preparing For and Using 3rd Party Control Libraries for Rich Internet Applications (RIA)
This series of short video presentations walks you through the steps involved in laying the foundation within OpenEdge to allow you to develop a modern user interface using one or more 3rd-part technologies that support what we call RIA, for Rich Internet Applications. There are a wide variety of such products that can communicate with an OpenEdge application using the OpenEdge AppServer, WebSpeed, or Web services. This video series, and the white papers that accompany it, review the different ways you can establish a connection to OpenEdge business logic and data management code running on the server side of your application, and provide an introduction to some of the libraries and plug-ins that are available for building the user interface on the client side. This initial series of videos and papers will be extended over time to show additional RIA alternatives.
This video introduces the OpenEdge Explorer tool for managing AppServers, WebSpeed brokers, and Web Service Adapters, and uses it to configure and start a sample AppServer.
In answer to both questions (this post and the next), the code samples are embedded in the paper that accompanies the ExtJS series. In other papers the complete code sample have been repeated at the end of the paper to make them easier to copy and paste (and easier to keep in sync with the content of the presentations). In this case, I see that viewcustomers.js is in several pieces in the document, with descriptive comments in between, which is a nuisance. Sorry for that. I will endeavor to repost the paper with the code samples complete.
John, can you put together all the files as a zip that we can download ? Thanks
Thank you for this series.I'm trying to work with ExtJS. I got to do your examples. I have it working. But I have a question, how to make changes in ExtJS -> READ-JSON -> WebSpeed to the table? For example, if I changed one record from customer table. Could you describe an example?
