Chapter 6. SQL Developer Accessibility

SQL Developer has a Connections node for establishing a database session with the target database. The connections may be either newly created or an imported and existing connection that we already had in the previous version of SQL Developer. To create a new database connection, right-click on the Connections node and select New Database Connection. You can also connect to schemas for MySQL, TimesTen, and Hive, as well as some select third-party (non-Oracle) databases, such as Microsoft SQL Server, Sybase Adaptive Server, and IBM DB2, to view metadata and data. However, providing details on such third-party database connections are out of scope of this book. The existing connections are always displayed in the connections pane automatically every time the SQL Developer is started. This list of existing connections is fetched from either tnsnames.ora file (if it exists); otherwise, the connections information is stored in a connections.xml file under C:Users212391205AppDataRoamingSQLDevelopersystem4.1.0.19.07o.jdeveloper.db.connection.12.2.1.0.42.150416.1320.

Screen reader readability

Screen reader readability is based on the US Federal law of 1973, under which all electronic and information technology products and services meet the standards which can provide an extension, that can be used by people with disabilities.

The following of technologies provide the screen reader readability feature:

  • Java J2SE 1.6.0_24 or higher, but one that comes before Java 7 Update 6 (you need to manually install Java Access Bridge 2.0.2 after you install the screen reader).
  • Java Access Bridge for Windows version 2.0.2. This can be downloaded; the file you will download is accessbridge-2_0_2-fcs-bin-b06.zip. It is available at http://www.oracle.com/technetwork/java/javase/tech/index-jsp-136191.html.
  • JAWS 12.0.522 (Job Access With Speech)

To set up a screen reader and Java Access Bridge, use the following procedure:

  1. Install the screen reader. Oracle recommends JAWS, which can be downloaded from http://www.freedomscientific.com/Products/Blindness/JAWS.
  2. Install SQL Developer 4.1; we already have one.
  3. Download and Install Java Access Bridge version 2.0.1 for Windows' 32-or 64-bit version. It is available at http://www.oracle.com/technetwork/java/javase/tech/index-jsp-136191.html.
  4. Confirm that the following files have been installed in the Windows System32 directory or copy them from C:accessbridge_homeinstallerfiles because they must be in the system path in order to work with SQL Developer:
    • JavaAccessBridge.dll
    • JAWTAccessBridge.dll
    • WindowsAccessBridge.dll
  5. Confirm that the following files have been installed in the C:Program FilesJavajdk1.8.0_45jrelibext directory, or copy them from C:accessbridge_homeinstallerfiles:
    • access-bridge.jar
    • jaccess-1_4.jar
  6. Confirm that the accessibility.properties file has been installed in the C:Program FilesJavajdk1.8.0_45jrelib directory, or copy it from C:accessbridge_homeinstallerfiles.
  7. Start screen reader.
  8. Start SQL Developer by running the sqldeveloper.exe file located in the C:sqldeveloper-4.1.0.19.07-no-jresqldeveloper folder.
