Do you want to run it embedded or start a no-kidding network server? 
The documentation for using it as an embedded server is reasonably 
good, but I could send you and example if you want.

Subject: how to startup the xindice server in a java program
Hi,
I am a beginner in Xindice and not a skilled programmer in java. I am 
trying to write something like a Xindice GUI.The first problem which 
I encounterd is how to startup the Xindice server in the java program 
but not in a command line. In javadoc I find a class named Shutdown, 
but nothing about the startup of the server. and in startup.bat, they 
use the class org.apache.xindice.server.Xindice. but that is a 
abstract class. I don't know how it worked.
How could I startup the xindice server in a java program not in a 
command line?
Any suggestions would be appreciated.

For what it's worth, here's my XMLDBUtil class. You must do 
XMLDBUtil.initializeDatabase() first, then you can add, remove, etc, 
collections and documents. I'm just not sure about index creation at the mo.
