Unable to start iDRAC7 due to missing jars in classpath

Note: I am no java expert so how I have solved this issue for myself may be completely wrong, but it works.

Starting the iDRAC7 KVM client fails with the following error

javax.xml.parsers.DocumentBuilderFactory: Provider org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found

Adding the following to javaws.sh fixes this

for F in /usr/share/java/*.jar; do
  LAUNCHER_BOOTCLASSPATH="$LAUNCHER_BOOTCLASSPATH:$F"
done
