The Palm Phone Library is an interface to phone hardware. Its usage is increasingly gaining importance as developers are developing many applications involving the use of Phone APIs. It is widely used in the organizations mainly responsible for developing applications involving phone feature's usage. Examples include Phone call recording, Black list (used to ignore a particular caller), Caller identification, Customized ringtones, Conferencing, etc.

Handsets are numerous in the cellphones market, and new ones enter every day. These handsets vary on several parameters like screen size, heap size, maximum application size, apart from special-key layout and form factors. It is possible to design and write J2ME applications in a manner that reduces the effort in porting across handsets. This thought-provoking article discusses possible approaches.

Game programming is exciting work, just as gaming is exciting play! This article discusses beginner steps in writing games using Sun's J2ME programming technologies. J2ME is a dedicated version of the normal J2SE, designed specifically for device/cell-phone platforms and their inherent constraints. Key small-device usage and performance considerations to be kept in mind and the first few steps into J2ME programming are discussed in this article.

Traditionally, JDBC has been the data access model of choice for most Java developers. The introduction of Hibernate brings Object-Relational Mapping (ORM) as a data storage/access solution. Hibernate is quite naturally suited to the Object-Oriented way of thinking, and to a pure Object-Oriented language such as Java. In this article we discuss the merits and demerits of each approach. Hibernate in general has advantages, but in specific situations the use of JDBC may be advisable.

The separation of design and programming has been a priority for web application development environments. Designers and programmers are different sets of people, and each would like to make changes independently; this separation allows such workflows to exist. Second-generation Java web development achieved this using JSP and JSP Include files. The current generation of Struts MVC frameworks brings with it Struts Tiles, an advanced method of achieving UI-code or design-program separation. In this article, we discuss the advantages we see in the Struts Tiles approach, and list some demerits as well.

This article focuses on an often-neglected but all-important aspect of any software application – the user interface. For years, desktop applications have had boring gray rectangular windows, buttons etc. Animation, multi-media, visual effects and custom elements were possible, but required large amount of custom programming. Even making a non-rectangular button would need good C++ skills. The web and its use of Flash change the equation. Web-based applications look far more attractive and user-friendly than comparable desktop application, but are easy to develop with Flash. In this article, we present ideas for using Flash inside VB applications, thus injecting new life into desktop software products.

Macromedia supports Mindfire's approach towards VB-Flash integration, and this article has been published by Macromedia here.

This paper discusses a RMI driven approach to building Web Services for an existing Java Application. We deal with the basics of JAX-RPC and steps in using Sun's Java Web Services Developer Pack (JWSDP). We describe the architecture and process used to implement a Web Services wrapper layer over an existing RMI-enabled Java application.

Checklist-driven testing can encapsulate the cumulative experience and knowledge of teams, raising productivity and coverage significantly in test efforts. This paper discusses about the various advantages and disadvantages related to checklist-driven testing. While identifying problem areas in checklists, it also intends to supply work-around to attack these problems.

This paper propels the goodness of custom-made checklists and aims to help test organizations build their own checklists. Creation and selection of items for a checklist can be the make-or-break of a checklist strategy.

When Test Organizations plan serious implementation of checklist driven testing, systematic approach to deal with these rapidly growing custom checklists becomes a critical factor. It is not only difficult to manage growing number of checklists, but also successful implementation becomes questionable. This document describes how checklists can be further classified according to their usage and hence be organized.

This paper discusses the techniques and methods in porting an existing ASP application to the ASP .NET technology. It also talks about issues faced in porting of existing ADO-to-ADO .NET technology and suggests appropriate steps that should be used to make the whole process simpler.

Porting: Development Techniques

This paper discusses software-porting process in details highlighting the steps involved in the process. It also talks about significant issues faced in a typical porting process and suggests appropriate strategies that should be used to make the whole process simpler.

Porting: Test Techniques

While justifying the need of a separate testing strategy for ported applications, this paper discusses testing methodology for porting projects. Portions of this document talk about the stage-wise testing approach and then elaborate each one to create a substantial and comprehensive process. Best practices gained from practical experiences make this paper a good guide for testing software ports.

Porting: A Business Decision

Porting is a significant, if oft-neglected, strategy for software businesses. Multi-platform products have multiple benefits, while bringing with them possible headaches. The porting process itself carries a few risks. In this white paper, we discuss the pros and cons of porting. We also consider some pitfalls, and finally outline options available for porting.
