Information Requirement Elicitation (IRE) is essential in wireless web service to elicit information requirements through interactive choice prompts. We present a high-level user interface for an IRE-enabled information system, in the context of database queries by a mobile web user. The prototype is based on the notion of a Query-By-Object (QBO) approach of building a query using multiple user-level steps. The test prototype system uses the Mobile Information Devices Profile (AEDP) of the java 2 platform, microedition (J2ME), for a wireless front end, and a java 2 platform, Enterprise edition (J2EE) application server and an Object-Relational Database Management System (ORDBMS) at the back end A sample set of dynamic queries demonstrate ease of use by the users.

In this paper, we propose a new framework for developing 3D graphic applications on portable devices such as cellular phones or personal digital assistants (PDAs). Our framework is based on J2ME (java 2 platform, microedition) environment, an application environment that specifically addresses the needs of developing programs on embedded systems using java, and we leverage the advantages of J2ME to build our platform-independent 3D graphic library on mobile devices. Adopting this framework, the 3D program developers can not only implement a cross-platform 3D program easily as they did using OpenGL ES2 library but also gain the powerful features including efficient memory usage and shading functionalities.
