Setting up eXist database with OpenLaszlo

While trying to install eXist in the OL environment, I did the follwing changes to make it run.

1. Make the standalone installation by using the eXist.jar file ( installation is a simple process ).
2. Then copy exist[ver..].war file to the C:\Program Files\OpenLaszlo Server 4.0b1\Server\tomcat-5.0.24\webapps\exist" location. Start OpenLaszlo, it will extract all files there.
3. Copy the lib folder from the exist installation to "C:\Program Files\OpenLaszlo Server 4.0b1\Server\tomcat-5.0.24\webapps\exist" location.
4. Go to the C:\Program Files\OpenLaszlo Server 4.0b1\Server\tomcat-5.0.24\bin folder and edit the catalina.bat file. Add the following lines :

set JAVA_ENDORSED_DIRS=%CATALINA_HOME%\webapps\exist\lib\endorsed

Restart OL and then eXist will start running by this URL : http://127.0.0.1:8080/exist/index.xml
