Java Modeling: A UML workbook, Part 3
you into the gray zone between modeling and method, with a look at requirements gathering via use case modeling. In particular, he focuses on the relationship between user interfaces, system interfaces, and use case descriptions. While tempting to do so, it is generally considered bad form to include user interface logic in a use case.

Data Wizard for Java
Data Wizard for Java is a tool for building a simple graphical user interface (GUI) that makes it easy to collect necessary data. This tool enables the building of data wizard applications using only a scripting scenario in an XML format. Data Wizard for Java can help to produce a GUI by using a simple script to describe the necessary input parameters and the required tools or utilities to be called.

Interfaces in Java
In Java, a class can have at the most one immediate superclass. Multiple inheritance, where a class has more than one superclass, is not allowed in Java. However, one cannot ignore the importance of multiple inheritance because a large number of real-life applications require the use of multiple inheritance. Java provides an alternative approach to support multiple inheritance by introducing a new data type known as interfaces. Although a class cannot inherit multiple classes, it can implement more than one interface.

Data Reading and Writing
Many of the values used in your program simply allow you to display them to the user. In some cases, you may want to request values from the user. As we saw in the previous lesson, there are various types of values you would need the user to supply. Some times the user will clearly understand your request. Some times either your request will not be clear or the user would be playing with the program.

Introduction to Servlets
For creating dynamic web applications we need some server resources which process user requests and send response back to user. Typical examples are processing HTML form, database query and sending dynamic HTML content back to user. Early days, we used CGI programs based on scripting languages like Perl, PHP etc. Java Servlets is an alternative to CGI programs based on popular Java programming language.

Creating a Browser Detection JavaBean
In this article we will build a browser detection JavaBean which as the name suggests will try to detect your browser and display a useful message. You can use this bean as such or improve it to your liking. It is a very simple and light weight bean and should not take much memory on your server. You can use it on your site to detect user browser and render appropriate HTML to the user.

Variables and Data Types
A typical program uses various values and these values keep changing while the program is running. For example, you create a program that is used to perform calculations, the values entered by one user will obviously be different from the values entered by another user. This also means that, when creating the program, you cannot know all possible values that will be entered in your program. You should still be able to manage the values that the users will eventually enter in your program.

Building your first Enterprise JavaBean.
In this tutorial we will learn how to create our first Enterprise JavaBean. We will then deploy this EJB on a production class, open source, and free EJB Server; JBoss. JBoss is a really popular EJB Container and is used by quite a lot of organizations World wide. We will thus also learn how to install and run JBoss Server. The client for our EJB will be a JSP page running in a separate Tomcat Server.
