How This Guide Is Organized

This guide provides instructions for the development and the deployment of Web services to Sun ONE Application Server. The guide also provides information on developing client applications that can invoke Web services.

Chapter 1, "About Web Services"

This chapter introduces you to Web services and the standards used in implementing Web services. Also discusses about the working of Web services in the Sun ONE Application Server environment.

Chapter 2, "Services and Clients Using JAX-RPC"

This chapter describes the procedure to develop, deploy, execute JAX-RPC Web services and clients that access such services.

Chapter 3, "SOAP Clients and Services Using SAAJ and JAXM"

This chapter introduces you to the SAAJ and JAXM APIs, how to use these APIs to develop message-oriented services and clients in Sun ONE Application Server environment.

Chapter 4, "Clients Using JAXR"

This chapter introduces you to the JAXR API, how to use the API to build clients, and how to manage the registry data.

Appendix A, "XML Schema Definitions"

This appendix provides XML Schema Definitions for the various configuration files used in developing JAX-RPC Web services and clients.

Finally, a Glossary and Index are provided.

Documentation Conventions

This section describes the types of conventions used throughout this guide:

General Conventions
Conventions Referring to Directories

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 path:

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.

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/domains which 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.
