Learn how to implement a dynamic user interface through user authentication. Authentication is often the requirement for applications with multiple groups of users. Each group may require access to application functionality that may need to be withheld from other groups. The authentication mechanism must validate user credentials and control access to application functionality based on the user's credentials. This article shows how to implement a basic authentication mechanism using OpenLDAP and Tomcat. It compares the OpenLDAP and Tomcat implementation to an OpenLDAP and WASCE implementation. And finally, code examples show the implementation of the dynamic UI using Java code and JSTL.

|Adaptive user interfaces for health care
Adaptive user interfaces assist users in accomplishing tasks in an application and construct a model of the user's preferences so as to serve them better in the future. Examples include systems that filter news stories, recommend products, and so on. This approach to personalized services is relatively new but has great potential for improving the effectiveness of human-computer interfaces. Health care is a significant area where adaptive user interfaces can be of great use. Health care users range from having little computer knowledge (for example, some nurses or doctors) to having expert computer knowledge (for example, system administrators). And, there can be many other distinguishing factors when it comes to patients. Therefore, adapting a computer application's interface to different types of users is important to improve the usability of such applications. Two major techniques used for adaptation are adaptive presentation and adaptive navigation. Adaptive presentation involves personalizing the contents presented to the user. Adaptive navigation involves customizing ways by which users complete their tasks in the application. These techniques can be used to enhance the usability of health care applications, thereby contributing to their success.

|Web development tips: Pay attention to the CSS @media rule
The CSS "@media" rule is a useful way to target an HTML or XML document to an intended output device. Use of the "print" media is now fairly widespread, and provides a much cleaner means of creating printer-friendly pages than does a separate "printable version." The use of the "screen" media has been somewhat underused, perhaps because of an overly general assumption that screen is merely the "default rendering." However, in regard to positioning--especially absolute positioning--the screen media type has an important meaning that is not covered by media-free stylesheet rules.

|Quality busters: Make your error messages meaningful
Many applications treat users as if they were programmers. Messages that report errors are often cryptic, contain meaningless codes, and provide no help regarding what to do next. While the developers who wrote the application can use those messages, most users are left with one option: call the help desk. This article describes a more appropriate kind of error message for users: one that includes description, cause, and recovery steps.

|Quality busters: Don't violate the principle of locality
Modern applications are highly distributed, with components residing on many systems. These components consist of many application objects, such as program modules, databases, and configuration files. Improperly distributing application objects increases the number of necessary maintenance tasks; this in turn increases the likelihood that a task might be performed incorrectly, which increases the probability of an application failure. In this installment of Quality busters, you'll look at some of the ways in which application objects are improperly distributed.

|Quality busters: The files that ate the disk
Nearly every application creates by-products which must be managed. These by-products include log files, tracings for debugging problems, intermediate files, data transfer files, temporary tables, and more. Failure to manage these transient objects can result in the application's failure due to limited disk space or other resource conflicts.

|Quality busters: Forget the environment
The quality of an application depends on more than how well it satisfies user-functional requirements. Even an application that successfully makes it through development and deployment can encounter grumblings from users and system operators if it is hard to use, keeps failing, is difficult to diagnose, or consumes excessive resources. In addition to user-functional requirements, you must also consider how well the application satisfies the non-functional requirements and fits into the organization's operational environment.

|Fly on the Wall
For developers to make products that delight customers, they need adequate information about who exactly the customers are and what their requirements are. The User-Centered Design (UCD) process provides numerous options for gathering both customer and user input, with wide variation regarding the time involved, labor required, overhead costs, and validity of the information collected. The "Fly on the Wall" (FOTW) technique is a low-cost, low-overhead method of collecting valid customer data. The method is illustrated here through a pilot study that used first-hand, unobtrusive observations by UCD practitioners to collect valid customer data in a timely, cost-effective manner in collaboration with development and marketing staff.
