JSP 2.0 Reusable Dialog Components (RDC) is a framework for creating JSP taglibs that aid in rapid development of voice and multimodal applications.
Server-side generation of HTML has proven an effective way of generating the user interface for visual Web applications that are implemented using server-side application frameworks such as Struts. Over time, the effort involved in such HTML generation has been reduced by the availability of various JSP tag libraries that abstract away the minutiae of HTML markup. The goal of the RDC project is to achieve for voice applications what JSP tag libraries have already achieved in the world of visual Web applications.
The voice application space is seeing rapid growth with the maturation of speech technologies along with the arrival of a stable and robust voice programming model as defined in the W3C VoiceXML 2.0 REC few years ago. A necessary next step in mainstreaming the development of server-side voice applications within environments like Tomcat is the availability of the appropriate tag libraries that help isolate the JSP developer from the intricacies of spoken interaction. The goal is to help package specialized speech design skills in the form of JSP tag libraries that make it possible for JSP developers to easily speech-enable Web applications.
The RDC taglib project provides the following pieces:
The code is under active development, and we are continuing to evolve and enrich the basic framework as we exercise the presently available functionality by authoring new components and by using these components in real-world voice applications.
All components in the RDC taglib produce VoiceXML 2.0 that can be served to any VoiceXML 2.0 compliant voice browser. The generated applications can be deployed to a standard Tomcat server and be accessed by a VoiceXML 2.0 compliant voice browser.
This tag library requires JSP 2.0 support and has been developed on Tomcat 5.5. It depends on the following libraries, many of which can be obtained from various Apache projects:
A majority of the tags implemented by this tag library have been created as .tag files. Tag handlers implemented in Java extend JSP 2.0's SimpleTagSupport .
