Preface

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:

Intended Audience

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:

To use this document, you need knowledge of Java, Oracle Database, SQL, PL/SQL, and JDBC.

Documentation Accessibility

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. For more information, visit the Oracle Accessibility Program Web site at

http://www.oracle.com/accessibility/

Accessibility of Code Examples in Documentation

Screen readers may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, some screen readers may not always read a line of text that consists solely of a bracket or brace.

Accessibility of Links to External Web Sites in Documentation

This documentation may contain links to Web sites of other companies or organizations that Oracle does not own or control. Oracle neither evaluates nor makes any representations regarding the accessibility of these Web sites.

TTY Access to Oracle Support Services

Oracle provides dedicated Text Telephone (TTY) access to Oracle Support Services within the United States of America 24 hours a day, seven days a week. For TTY support, call 800.446.2398.

Structure

This document contains:

Chapter 1, "Introduction to JPublisher"

Introduces the JPublisher utility by way of examples, lists new features in this release, and provides an overview of JPublisher operations.

Chapter 2, "Using JPublisher"

Describes how you can use JPublisher for publishing SQL and PL/SQL objects, Oracle Stream Advanced Queue (AQ), server-side Java classes, and Web services.

Chapter 3, "Data Type and Java-to-Java Type Mappings"

Provides details of JPublisher data type mappings and the styles mechanism for Java-to-Java type mappings.

Chapter 4, "Generated Classes and Interfaces"

Discusses details and concepts of the classes, interfaces, and subclasses generated by JPublisher, including how output parameters (PL/SQL IN OUT or OUT parameters) are treated, how overloaded methods are translated, and how the generated classes and interfaces are used.

Chapter 5, "Additional Features and Considerations"

Covers additional JPublisher features and considerations: a summary of support for Web services, filtering of JPublisher output, and migration and backward compatibility.

Chapter 6, "Command-Line Options and Input Files"

Provides details of the JPublisher command-line syntax, command-line options and their usage, and input file format.

Appendix A, "Generated Code Examples"

Contains code examples that are too lengthy to fit conveniently with corresponding material earlier in the manual. This includes examples of Java-to-Java type transformations to support Web services, and Java and PL/SQL wrappers to support Web services.

Appendix B, "Troubleshooting"

Covers the troubleshooting tips for JPublisher

Conventions

This section describes the conventions used in the text and code examples of this documentation set. It describes:

Conventions in Text

We use various conventions in text to help you quickly identify special terms. The following table describes these conventions and provides examples of their use.

Convention Meaning Example
Bold Bold typeface indicates terms defined in the text. A class is a blueprint that defines the variables and the methods common to all objects of a certain kind.
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 BACKUP command.

Query the TABLE_NAME column in the USER_TABLES data dictionary view.

Use the DBMS_STATS.GENERATE_STATS procedure.

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 orapwd file.

Back up the data files and control files in the /disk1/oracle/dbs directory.

The department_id, department_name, and location_id columns are in the hr.departments table.

Set the QUERY_REWRITE_ENABLED initialization parameter to true.

The JRepUtil class implements these methods.

lowercase italic monospace (fixed-width) font Lowercase italic monospace font represents placeholders or variables. You can specify the parallel_clause.

Run old_release.SQL where old_release refers to the release you installed prior to upgrading.


Conventions in Code Examples

Code examples illustrate Java, SQL, PL/SQL, SQL*Plus, or command-line statements. They are displayed in a monospace (fixed-width) font and separated from normal text as shown in this example:

SELECT username FROM dba_users WHERE username = 'MIGRATE';

The following table describes typographic conventions used in code examples and provides examples of their use.

Convention Meaning Example
[ ]
Brackets enclose one or more optional items. Do not enter the brackets.
DECIMAL (digits [ , precision ])
{ }
Braces enclose two or more items, one of which is required. Do not enter the braces.
{ENABLE | DISABLE}
|
A vertical bar represents a choice of two or more options within brackets or braces. Enter one of the options. Do not enter the vertical bar.
{ENABLE | DISABLE}
[COMPRESS | NOCOMPRESS]
...
Horizontal ellipsis points indicate either:
  • That we have omitted parts of the code that are not directly related to the example

  • That you can repeat a portion of the code

CREATE TABLE ... AS subquery;

SELECT col1, col2, ... , coln FROM employees;
Other notation You must enter symbols other than brackets, braces, vertical bars, and ellipsis points as shown.
acctbal NUMBER(11,2);
acct    CONSTANT NUMBER(4) := 3;
Italics
Italicized text indicates placeholders or variables for which you must supply particular values.
CONNECT SYSTEM/system_password
DB_NAME = database_name
UPPERCASE
Uppercase typeface indicates elements supplied by the system. We show these terms in uppercase in order to distinguish them from terms you define. Unless terms appear in brackets, enter them in the order and with the spelling shown. However, because these terms are not case-sensitive, you can enter them in lowercase.
SELECT last_name, employee_id FROM employees;
SELECT * FROM USER_TABLES;
DROP TABLE hr.employees;
lowercase
Lowercase typeface indicates programmatic elements that you supply. For example, lowercase indicates names of tables, columns, or files.

Note: Some programmatic elements use a mixture of UPPERCASE and lowercase. Enter these elements as shown.

SELECT last_name, employee_id FROM employees;
sqlplus hr/hr
CREATE USER mjones IDENTIFIED BY ty3MU9;
