<h2>Using OpenOffice Base</h2>
OpenOffice.org Base supports database access over the JDBC API. To connect to a H2 database
using OpenOffice Base, you first need to add the JDBC driver to OpenOffice.
The steps to connect to a H2 database are:
<ul>
<li>Stop OpenOffice, including the autostart
<li>Copy h2.jar into the directory &lt;OpenOffice&gt;\program\classes
<li>Start OpenOffice Base
<li>Connect to an existing database, select JDBC, [Next]
<li>Example datasource URL: jdbc:h2:c:/temp/test
<li>JDBC driver class: org.h2.Driver
