how to startup the xindice server in a java program

[showery <sh...@ccs2000.cla.kobe-u.ac.jp>]

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.
