I stumbled across Hunt and Mirror and wondered how to be able to use it.

I am using Greenstone 2.40 on a Windows XP Professional computer.

The help file says you have to use the
-mirror
Argument. I tried it in the command line and changing the gatherer.bat file.
Neither worked.

Next, I modified the GLIconfig.xml file:
I changed workflow.mirror argument to TRUE.
This brought up the Mirror tab (tho not the Hunt tab mentioned in the help
file).
It also caused the following Java error, reported in the Command Prompt box:

java.lang.NullPointerException
at org.greenstone.gatherer.gui.GUIManager.afterDisplay(GUIMana39)
at org.greenstone.gatherer.Gatherer.run(Gatherer.java:268)
at org.greenstone.gatherer.Gatherer.main(Gatherer.java:532)

When I tried entering a URL and downloading, nothing happens

What am I missing?
