Oracle avoids JavaScript in RIA tools

Oracle Corp. continues to pursue its agnostic approach to Web 2.0 development as its tools designed to help developers create Ajax without having to mess with JavaScript progress through beta, says Ted Farrell, chief architect and vice president for tools and middleware at Oracle.

In an interview discussing the Oracle approach to the problematic nature of JavaScript this past fall, Farrell said: “In the Ajax space, JavaScript access to portlets and data sharing is very difficult and in a lot of cases, it’s actually impossible.”

His opinion hasn’t changed. Speaking this past week about the Oracle tool development that relies on Java Server Faces (JSF) to spare coders from JavaScript, Farrell said, “We don’t want our developers programming in JavaScript, which is a pain in the neck.”

Oracle has standardized on a JavaServer Faces (JSF)-based RenderKit, which allows the developer who has learned JSF to assemble disparate components into a Web 2.0-style mashup.

Enterprise customers are looking for ways to avoid getting caught up in such complexities, so the philosophy behind the tools Oracle has in beta is to automate the rendering technologies, so developers only need to work with components and pages, he said. This approach also is designed to insulate developers from the on-going changes in underlying technologies for RIA, he said.

“As technologies change, we can changeĀ our framework but they don’t have to change their pages,” Farrell said.

He describes the Oracle RIA tools as “very WYSIWYG.” The developer designates that a page will be Ajax with Flash from Adobe Systems Inc., Farrell said, and that is all the coder needs to know about those technologies.

“You don’t have to learn those technologies,” he said, which in the case of Ajax is basically JavaScript. “Our visual editor will show you how the page is going to look. You can drag a component like a table onto the page. You can bind that to some backend databases or Web service, wherever you are getting the data from.”

Farrell said the Oracle RIA tools are in an advanced beta stage prior to the official release. Interested developers can find out more information and even download them from the Oracle Technology Network.

    Building RIA with server side presentation technologies is not only impossible but very indirect. Many enterprise applications are built using Visual Basic. Manuplating DOM using scripting language is simpler than putting control together except one hitch ... Microsoft had this beautiful tool for VB. JSF is overly complex programming model to begin with.

    The main headache with web development is trying to do cross browser stuff. Beyond that javascript is actually quite a joy to work with IMO because of the quick turn around (just refresh the page) and anyone with a first year understanding of pointers can quickly solve the quirks. Compare this with other tools like jsf or flex which require recompiling, restarting the web server, surfing the web because you are tired of waiting.... Really everyone wants to find something better but the reality is scripting languages give you much much more bang for the buck IMO.

    Curl is another RIA tool option where you just have to refresh the browser to see your changes. Curl also supports browserless applications similar to AIR, although Curl has been doing that longer. And Curl eliminates almost all of the cross browser differences.
