You are right. I changed the name, and it works. Thanks!

     I have a database located at

Is so what?
     I want to be able to connect to the database files using hsqldb 1.8. I can 
do this
if I use hsqldb 2.2.8. How do I do this using Base?



The Datasource URL:
        hsqldb:file:/home/<user 
name>/.openoffice.org/3/user/database/budget-personal/
The JDBC driver class:     org.hsqldb.jdbc.JDBCDriver
Class Path: /usr/local/hsqldb-2.2.8/hsqldb/lib/hsqldb.jar

     I removed 2.2.8 version of hsqldb from the Class Path.
Closed AOO.
Opened AOO.
Tools > Options > Java > Class Path.
There are not class paths listed.
Add Archive
Browsed to /opt/openoffice.org/basis3.4/program/classes/hsqldb.jar
Click OK twice.
Closed AOO
Opened AOO
Open the Base Wizard selecting "Connect to an existing database": JDBC.
Click Next.
Entered the Datasource URL as above.
Entered the JDBC driver class: org.hsqldb.jdbc.JDBCDriver

I missed the wrong driver: org.hsqldb.jdbcDriver is the correct one.
This will work with 2.2.8, too.

Clicked "Test class".
Error message appears: The JDBC driver could not be loaded.

What is wrong with these steps? I can follow the very same steps, this time 
using the
latest version of hsqldb (/usr/local/hsqldb-2.2.8/lib/hsqldb.jar entered in the 
Class
Path). Then instead of an error message, the message tells me that the JDBC 
driver was
successfully loaded.
