The Sybase Java VM supports a subset of JDK version 2.0 (UNIX and Windows NT) classes and packages.
The Sybase runtime Java classes are the low-level classes installed to Java-enable a database. They are downloaded automatically when Adaptive Server is installed and are available thereafter from $SYBASE /$SYBASE_ASE/lib/runtime.zip (UNIX) or %SYBASE%\%SYBASE_ASE%\lib\runtime.zip (Windows NT). You do not need to set the CLASSPATH environment variable specifically for Java in Adaptive Server.
Sybase does not support runtime Java packages and classes that assume a screen display, deal with networking and remote communications, or handle security. See Chapter 12, “Reference Topics” for a list of supported and unsupported packages and classes.
