Installing the JDK Software and Setting JAVA_HOME

If you do not already have the JDK software installed or if the JAVA_HOME environment variable is not set, the GlassFish ESB installation will not be successful. The following tasks provide the information you need to install the JDK software and set JAVA_HOME on UNIX or Windows systems.

To find out which JDK versions are supported for the platform you are using, see JDK and JAVA_HOME in Planning for GlassFish ESB Installation.

The GlassFish ESB Installer does not support JDK release 1.6.0_04 in the 64–bit version on the Solaris SPARC or AMD 64–bit environments.
