The text of the topic is shown below:

Hi,

I 'm trying to run Vacuum Database ext but I can't. I know that it is ext for 
PostgreSQL (My DB is Oracle), but I only want to know how to create and add ext 
to LiquiBase, because I gonnna create my own for Oracle.

I have already done all the steps (LiquidBase 2.0.1b is installed)

1. Add to classpath ext jar file.
2. Create XML file with simple example from web.
3. Create BAT file.

All files are in the same catalogue.

Content of files

#liquibase.properties

Code:
#liquibase.properties
driver: oracle.jdbc.OracleDriver
classpath: ojdbc14.jar;liquibase-vacuum-1.0.jar
url: jdbc:oracle:thin:@<myIP>:1521:XE
username: <myLogin>
password: <myPass>

#vacuum.xml

Code:
<databaseChangeLog
       xmlns="http://www.liquibase.org/xml/ns/dbchangelog";
       xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext";
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
       xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog 
http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-2.0.xsd
       http://www.liquibase.org/xml/ns/dbchangelog-ext 
http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd";>
   <changeSet id="1" author="nvoxland" runInTransaction="false">
       <ext:vacuum/>
   </changeSet>

</databaseChangeLog>

#update.bat

Code:
@echo off
call liquibase --changeLogFile=vacuum.xml update

Massage during executing update.bat

Code:
org.xml.sax.SAXException: Unknown LiquiBase extension: vacuum.  Are you missing 
a jar from your classpath?

Migration Failed: Unknown LiquiBase extension: vacuum.  Are you missing a jar

I have no idea why it doesn't work.
