About the Java Development Kit
The BIRT iHub installation routine installs the Java SDK files under the directory specified in the environment variable AC_SERVER_HOME:
AC_SERVER_HOME/jdk160
Some operating systems require an operating system upgrade or patch to use JRE 6.0. For information about requirements for your operating system, see your operating system documentation. Also, see the Actuate Support Lifecycle Policy and Supported Products Matrix on the Actuate Support web site. You can access the Support site at the following URL:
To use a different JDK with iHub, change the files in the installation directory or change the values of the following Linux environment variables:

AC_JAVA_HOME

AC_JVM_HOME

AC_JRE_HOME in the PMD startup script, pmd11.sh

AC_JRE64_HOME
Using an earlier release of JDK can cause some Actuate features to fail or to work improperly. For example, using an earlier release of JDK can cause Actuate products to display Actuate charts incorrectly.
