Re: Fwd: [libreoffice-users] Re: LibreOffice-Base CPU usage

Hi :)
Thanks Don.  I think you might be able to convert/export/migrate your back-end to a different one.  
I don't think you have to stick with HSql.  I'm not sure if it's possible to remove java dependence 
when using HSql, i thought it was but i could be wrong.
Regards from
Tom :)

Hi All,

I set up base shortly after it was added to Open Office. Apparently I am 
using the embedded database - HSQL database engine. If I turn off Java 
(I just tried it.), I get the following error message:
The connection to the data source "RE Database" could not be 
established. No SDBC driver was found for the given URL.

I cannot open my database without Java enabled. So using the database 
included with base will not work without Java.
