This book contains information about how to build distributed applications that run on Sybase EAServer.
The EAServer Programmer’s Guide is written for application developers who are familiar with their chosen programming languages, specifically Java, C++, C, or an ActiveX scripting language.
Though you do not need to know all of these languages to create EAServer components or clients, the chapters that pertain to each language assume a basic familiarity with that language.

EAServer has been tested for compliance with U.S. government Section 508 Accessibility requirements. The online help for this product is also provided in HTML, JavaHelp, and Eclipse help formats, which you can navigate using a screen reader.
EAServer Manager supports working without a mouse. For more information, see “Keyboard navigation” in Chapter 2, “Sybase Central Overview,” in the EAServer System Administration Guide.
The WST plug-in for Eclipse supports accessibility features for those that cannot use a mouse, are visually impaired or have other special needs. For information about these features refer to Eclipse help:
Start Eclipse
Select Help | Help Contents
Enter Accessibility in the Search dialog box
Select Accessible user interfaces or Accessibility features for Eclipse
You might need to configure your accessibility tool
for optimal use. Some screen readers pronounce text based on its
case; for example, they pronounce ALL UPPERCASE TEXT as initials,
and MixedCase Text as words. You might find it helpful to configure
your tool to announce syntax conventions. Consult the documentation
for your tool.
For additional information about how Sybase supports accessibility, see Sybase Accessibility. The Sybase Accessibility site includes links to information on Section 508 and W3C standards.
