This preface introduces you to the Oracle Database JPublisher User's Guide, discussing the intended audience, structure, and conventions of this document. A list of related Oracle documents is also provided.
The JPublisher utility is for Java programmers who want classes in their applications to correspond to SQL or PL/SQL entities or server-side Java classes. In Oracle Database 10g, JPublisher also provides features supporting Web services call-ins to the database and call-outs from the database.
This preface covers the following topics:
The Oracle Database JPublisher User's Guide is intended for Java Database Connectivity (JDBC) and Java2 Platform, Enterprise Edition (J2EE) programmers who want to accomplish any of the following for database applications:
Create Java classes to map to SQL user-defined types, including object types, VARRAY
types, and nested table types
Create Java classes to map to OPAQUE
types
Create Java classes to map to PL/SQL packages
Create client-side Java stubs to call server-side Java classes
Publish SQL queries or data manipulation language (DML) statements as methods in Java classes
Create Java and PL/SQL wrappers for Web services client proxy classes
Publish server-side SQL, PL/SQL, or Java entities as Web services
To use this document, you need knowledge of Java, Oracle Database, SQL, PL/SQL, and JDBC.
Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.

From the Oracle Java Platform group, for Oracle Database releases:
Oracle Database Java Developer's Guide
This book introduces the basic concepts of Java in Oracle Database and provides general information about server-side configuration and functionality. It contains information that pertains to the Oracle Database Java environment in general, rather than to a particular product, such as JDBC.
The book also discusses Java stored procedures, which are programs that run directly in Oracle Database. With stored procedures (functions, procedures, and triggers), Java developers can implement business logic at the server level, which improves application performance, scalability, and security.
Oracle Database JDBC Developer's Guide and Reference
This book covers programming syntax and features of the Oracle implementation of the JDBC standard. This includes an overview of the Oracle JDBC drivers, the details of the Oracle implementation of JDBC 1.22, 2.0, and 3.0 features, and a discussion of Oracle JDBC type extensions and performance extensions.

Italics | Italic typeface indicates book titles and emphasis. | Oracle Database Concepts
Ensure that the recovery catalog and target database do not reside on the same disk. |
UPPERCASE monospace (fixed-width) font |
Uppercase monospace typeface indicates system elements. Such elements include parameters, privileges, data types (including user-defined types), RMAN keywords, SQL keywords, SQL*Plus or utility commands, packages and methods, as well as system-supplied column names, database objects and structures, user names, and roles. | You can specify this clause only for a NUMBER column.
You can back up the database by using the Query the Use the |
lowercase monospace (fixed-width) font |
Lowercase monospace typeface indicates executables, file names, directory names, and some user-supplied elements. Such elements include computer and database names, net service names, and connect identifiers, as well as Java packages and classes, program units, and parameter values.
Note: Some programmatic elements use a mixture of UPPERCASE and lowercase. Enter these elements as shown. |
Enter sqlplus to start SQL*Plus.
The password is specified in the Back up the data files and control files in the The Set the The |
