 * This activator is used when glassfish.jar is installed and started
 * in an existing OSGi runtime. It expects install root and instance root
 * to be set via framework context properties called com.sun.aas.installRoot and com.sun.aas.instanceRoot
 * respectively. The former one refers to the directory where glassfish is installed.
 * (e.g., /tmp/glassfish3/glassfish)
 * The latter one refers to the domain directory - this is a directory containing
 * configuration information and deployed applications, etc.
 * If instance root is not set, it defaults to $installRoot/domains/domain1/.
