Installing the JDK Software and Setting JAVA_HOME

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

The following list provides the Java CAPS JDK requirements by platform.

Solaris

JDK5: At least release 1.5.0_14

JDK6: At least release 1.6.0_03

IBM AIX

JDK5: The latest 1.5 release supported by IBM AIX

Linux (Red Hat and SUSE)

JDK5: At least release 1.5.0_14

JDK6: At least release 1.6.0_03

Macintosh

JDK5: The latest 1.5 release supported by Apple

Microsoft Windows

JDK5: At least release 1.5.0_14

JDK6: At least release 1.6.0_03

It is not recommended to user JDK 1.6.0_13 or 1.6.0_14 with Java CAPS due to issues with several of the wizards used to develop applications. In addition, the installation fails on Windows when using JDK 1.6.0_13 or 1.6.0_14. The Java CAPS Installer does not support JDK release 1.6.0_04 in the 64–bit version on Solaris SPARC or AMD 64–bit environments. The installer also does not support JDK 1.6.0 or later on AIX 5.3.
