Accessible Java applications are speech recognition systems, and refreshable braille displays u compatible with assistive technologies such as screen readers, screen magnifiers Documentation Accessibility For information about Oracle's commitment to accessibility, visit the Oracle AccessibilityProgramwebsiteathttp://www.oracle.com/pls/topic/lookup? ctx=acc&id=docacc Access to Oracle Support Oracle customers that have purchased support have access to electronic support throughMyOracleSupportForinformationvisithttp:/www.oracle.com/pls/topic/ lookup?ctx=acc&id=infoorvisithttp://www.oracle.com/pls/topic/lookup?ctx=acc&id=trs if you are hearing impaired Related Resources package How to Support Assistive Technologies in The Java Tutorials Java se 8 and earlier) package Conventions The following text conventions are used in this document Convention Meaning boldface Boldface type indicates graphical user interface elements associated with an action, or terms defined in text or the glossary italic Italic type indicates book titles, emphasis, or placeholder variables for which you supply particular values ORACL∈ Preface Convention MeanIng Monospace type indicates commands within a paragraph, URLS, code in examples, text that appears on the screen, or text that you enter ORACLE 1 Java accessibility Overview Java se provides java Access Bridge, Java Accessibility APl(JAAPD), and Java Accessibility Utilities to enable you to create accessible applications Topics Java Access bridge Java Accessibility API Java accessibility Utilities Pluggable Look and Feel Java Access bridge Java Access Bridge enables certain Java applications and applets to be visible to assistive technologies on Microsoft Windows. See Enabling and Testing Java Access Bridge Java Accessibility AP The Java Accessibility API(JAAPD), contained in the package, is one of the core parts of the Java Foundation Classes(JFC). the JFCs are a comprehensive set of graphical user interface components and foundation services designed to simplify deployment of Internet, intranet and desktop applications. JAAPI enables you to create Java applications that are accessible to persons with disabilities Accessible Java applications are compatible with assistive technologies, such as screen readers, screen magnifiers, speech recognition systems, and refreshable braille displays. The JAAPI makes GUl component information available to assistive technologies, giving users alternative presentation and control of Java applications Support for JAAPI is built into Swing components; see How to Support Assistive Technologies in The Java Tutorials ( Java SE 8 and earlier) Java Accessibility Utilities Java accessibility Utilites, which is contained in the package is a set of utility classes that help assistive technologies provide access to GUl toolkits that implement the Java Accessibility API Java Accessibility Utilities monitor events related to Ul components. They also help assistive technologies get additional information about a gul, such as the current position of the mouse, or the window that currently has focus. See Java Accessibility Utilities overview Pluggable Look and Feel The Java Foundation Classes implement a Pluggable Look and Feel architecture. This architecture allows non-visual manifestations of a user interface to replace or enhance the visual presentation of an application. The expression of the user interface is accomplished by separating the user interface of the component from its model. The separated from the underlying structure and data of each individual component. This ORACLE Chapter 1 that is presented to the user by the user interface For more information on this oh model of a component is the structure which encapsulates the state and informa architecture, see About the JFC and Swing in the java Tutorials Java SE 8 and earlier) ORACLE 1-2 Java Access bridge overview Java access bridge is a technology that enables java applications and applets that mplement the java Accessibility aPi to be visible to assistive technologies on Microsoft Windows systems Java access Bridge is a technology that exposes the Java Accessibility API in a Microsoft Windows dynamic-link library(DLL), enabling Java applications and applets that implement the java Accessibility aPi to be visible to assistive technologies on Microsoft Windows systems In order for existing assistive technologies available on Microsoft Windows systems to provide access to Java applications, they need some way to communicate with Java Accessibility APl. Java Access Bridge supports this communication An assistive technology application running on Microsoft Windows (for example a screen reader) communicates with Java Access Bridge dlls, which in turn communicates with the java virtual machine through Java access bridge java libraries. These Java libraries communicate with Java Accessibility APl. Java Accessibility aPi collects information about what is happening in the java application which it forwards to the screen reader through Java Access Bridge Topics Enabling and Testing Java Access Bridge Java Access bridge architecture Java Access bridge aPl ORACLE 3 Enabling and Testing Java Access Bridge By default, Java Access Bridge is not enabled. Enable it either through the command line or the Windows Control Panel Test it by running a Java application that uses the Accessibility API TopICS Java Access Bridge Supported Java sE Platforms Enabling Java Access Bridge Through the Command Line Enabling Java Access Bridge Through the Control Panel Disabling Java Access Bridge Testing Java Access Bridge Java Access Bridge Tools Minimum Version Requirements of Assistive Technologies on 64-Bit Operating Systems Java Access bridge Supported Java SE Platforms Java access bridge is included with JRE 7u6 and later Enabling Java Access Bridge Through the Command Line Enable Java Access bridge with the comman Run the following command(where is the directory of your JRE) Enabling Java Access Bridge Through the Control Panel Enable Java Access Bridge through the Control Panel with the Ease of Access Center 1.
