| Sun ONE Application Server 7 Developer's Guide to Web Applications |
About This GuideThis guide describes how to create and run Java 2 Platform, Enterprise Edition (J2EE) applications that follow the new open Java standards model for Servlets and JavaServer Pages (JSPs) on the Sun™ Open Net Environment (Sun ONE) Application Server 7. In addition to describing programming concepts and tasks, this guide offers implementation tips and reference material.
This preface contains information about the following topics:

Who Should Use This Guide
The intended audience for this guide is the person who develops, assembles, and deploys web applications (servlets and JSPs) in a corporate enterprise.
This guide assumes you are familiar with the following topics:
- J2EE specification
- HTML
- Java programming
- Java APIs as defined in servlet, JSP, EJB, and JDBC specifications
- Structured database query languages such as SQL
- Relational database concepts
- Software development processes, including debugging and source code control
Using the Documentation
The Sun ONE Application Server manuals are available as online files in Portable Document Format (PDF) and Hypertext Markup Language (HTML) formats, at:
The following table lists tasks and concepts described in the Sun ONE Application Server manuals. The left column lists the tasks and concepts, and the right column lists the corresponding manuals.
How This Guide Is Organized
This guide provides a Sun ONE Application Server environment overview for designing web applications. The content is as follows:
- "Web Applications"
This module introduces web applications and describes how they are supported in Sun ONE Application Server.
- "Using Servlets"
This module describes how to create and use servlets.
- "Using JavaServer Pages"
This module describes how to create and use JavaServer Pages (JSPs).
- "Creating and Managing User Sessions"
This module describes how to create and manage a session that allows users and transaction information to persist between interactions.
- "Securing Web Applications"
This module describes how to write a secure web application for the Sun ONE Application Server.
- "Assembling and Deploying Web Modules"
This module describes how web modules are assembled and deployed in Sun ONE Application Server.
- "Using Server-Parsed HTML"
This module describes how to use server-parsed HTML with the Sun ONE Application Server.
- "Using CGI"
This module describes how to use CGI with the Sun ONE Application Server.
Finally, an Index is provided.
Documentation Conventions
This section describes the types of conventions used throughout this guide:
General Conventions
The following general conventions are used in this guide:
- File and directory paths are given in UNIX® format (with forward slashes separating directory names). For Windows versions, the directory paths are the same, except that backslashes are used to separate directories.
- URLs are given in the format:
http://server.domain/path/file.html
In these URLs, server is the server name where applications are run; domain is your Internet domain name; path is the server's directory structure; and file is an individual filename. Italic items in URLs are placeholders.
- Font conventions include:
The monospace font is used for sample code and code listings, API and language elements (such as function names and class names), file names, pathnames, directory names, and HTML tags.
Italic type is used for code variables.
Italic type is also used for book titles, emphasis, variables and placeholders, and words used in the literal sense.
Bold type is used as either a paragraph lead-in or to indicate words used in the literal sense.
- Installation root directories for most platforms are indicated by install_dir in this document. Exceptions are noted in Conventions Referring to Directories.
By default, the location of install_dir on most platforms is:
Solaris 8 non-package-based Evaluation installations:
user's home directory/sun/appserver7
Solaris unbundled, non-evaluation installations:
/opt/SUNWappserver7
Windows, all installations:
C:\Sun\AppServer7
For the platforms listed above, default_config_dir and install_config_dir are identical to install_dir. See Conventions Referring to Directories for exceptions and additional information.
- Instance root directories are indicated by instance_dir in this document, which is an abbreviation for the following:
default_config_dir/domains/domain/instance
- UNIX-specific descriptions throughout this manual apply to the Linux operating system as well, except where Linux is specifically mentioned.
Note Forte for Java 4.0 has been renamed to Sun ONE Studio 4 throughout this manual.
Conventions Referring to Directories
By default, when using the Solaris 8 and 9 package-based installation and the Solaris 9 bundled installation, the application server files are spread across several root directories. These directories are described in this section.
- For Solaris 9 bundled installations, this guide uses the following document conventions to correspond to the various default installation directories provided:
install_dir refers to /usr/appserver/, which contains the static portion of the installation image. All utilities, executables, and libraries that make up the application server reside in this location.
default_config_dir refers to /var/appserver/domains, which is the default location for any domains that are created.
install_config_dir refers to /etc/appserver/config, which contains installation-wide configuration information such as licenses and the master list of administrative domains configured for this installation.
- For Solaris 8 and 9 package-based, non-evaluation, unbundled installations, this guide uses the following document conventions to correspond to the various default installation directories provided:
install_dir refers to /opt/SUNWappserver7, which contains the static portion of the installation image. All utilities, executables, and libraries that make up the application server reside in this location.
default_config_dir refers to /var/opt/SUNWappserver7/domainswhich is the default location for any domains that are created.
install_config_dir refers to /etc/opt/SUNWappserver7/config, which contains installation-wide configuration information such as licenses and the master list of administrative domains configured for this installation.
