include more detailed information about a particular connection, such as object data or transaction characteristics The web page itself is a text file you can create using any text editor, such as Vi If you are familiar with tag-based word processing on Unix systems, you will find it conceptually similar to nroff Some HTML tags indicate headings, lists, and paragraphs, as well as links to reference web resources Instead of manually entering HTML or XML code, you can use web page composers A web page composer provides a graphical interface for constructing web pages Special web page creation programs can easily help you create complex web pages without ever having to type any HTML tags explicitly Remember, though, no matter what tool you use to create your web page, the web page itself will be an HTML document As part of the KDE project, KDE web Dev (kdewebdevorg) provides several web development applications, such as the Quanta Plus web editor and the Kommander dialog builder

features Many enable you to insert links or format headings For example, the KEdit program supports basic text-based web page components You can add headings, links, or lines, but not graphics

To develop Java applications, use Java tools, and run many Java products, you must install the Java 2 Software Development Kit (SDK) and the Java 2 Runtime Environment (JRE) on your system Together, they make up the Java 2 Platform, Standard Edition (J2SE) Sun currently supports and distributes Linux versions of these products You can download them from Sun at javasuncom/j2se and install them on your system Java packages and applications are listed in Table 14-4

Many Linux distributions include numerous free Java applications and support, like Jakarta, many of which were originally developed by the JPackage Project (jpackageorg) for use on Linux You should use your distribution s versions of these packages, as they may have been specially modified for use on it However, the main Java Runtime Environment and SDK are not included Instead, you either use an included compatible set of GNU packages (Java-like) that allow you to run Java applets, or install the JRE and SDK Linux ports from either JPackage or Blackdown, or download and install the original JRE and SDK from Sun None of these options are exclusive The JPackage service is available for RPM based distributions like Red Hat, SUSE, and Fedora, and the Blackdown package is popular with distributions like Debian and Ubuntu Moat distributions like Ubuntu, Fedora, and SUSE now include a Java-like collection of support packages that enable the use of Java Runtime operations There is no official name for this collection, though it is usually referred to as java-gci-compat, as well as Java-like This collection provides a free and open source environment, consisting of three packages: GNU Java runtime (libgcj), the Eclipse Java compiler (ecj), and, on Fedora, a set of wrappers and links (java-gcj-compat) Though Sun supports Linux versions of Java, more thorough and effective Linux ports of Java can be obtained from the Blackdown project at wwwblackdownorg Distributions like
