Uncomment and modify the following line at the beginning of "/opt/openfire/bin/openfire" script to override "JAVA_HOME":

INSTALL4J_JAVA_HOME_OVERRIDE=/opt/jre1.6.0_33

WARNING: This is not need if "echo $JAVA_HOME" point to a valid ORACLE Java 1.5 (or later) or OPENJDK installation path. Openfire does not works with "gcj" which can be installed on Ubuntu, check installed version executing "java -version".

Then just start it!
