[Trisquel-users] libreoffice base error

[maestro]

libreoffice works fine except for base - I can't open nor create a new  
database.I get:
"The connection to the data source "New Database" could not be established."
"SQL Status: HY000
The connection to the external data source could not be established. No SDBC  
driver was found for the URL 'sdbc:embedded:hsqldb'."

I have openjdk6 installed..
Can't figure out what is the problem :(

Any help is highly appreciated!
