I still get the long error message with "NoClassDefFoundError" during installation on Kubuntu, as mentioned in Common Problems.
I have installed, and confirmed the installation of libreoffice-java-common.
I have tried installing from within Libreoffice. I have downloaded the .oxt file and tried to load that in Libreoffice. Always the same error message.
Any further suggestions?
Kubuntu 11.10, the Oneiric Ocelot
