Optionally, you can install the entire Java Development Kit (JDK) instead of the JRE. The JDK requires more disk space and includes files and features that support development of Java applets and applications. Sybase does not provide the JDK (see step 1 in the following instructions).
Download the JDK for your operating system from the Java Software Web site: http://java.sun.com/products/jdk/1.1.
Double-click the file you downloaded.
Follow the installation instructions.
Add the following path to your CLASSPATH environment variable:
where x:\install_path is the location (drive and directory) where you installed the JDK; for example, c:\javasoft.
Add x:\install_path\bin to your PATH environment variable, where x:\install_path is the location (drive and directory) in which you installed the JDK; for example, c:\javasoft.
