I don't think you can use BTree class directly. Take a look at BTreeFiler - that 
should be better fit. Once you instantiate it, you need to pass in configuration 
and open it. Once you are done working with it, it needs to be closed.

See also org.apache.xindice.core.Collection, there you can see how to work with 
Filers.

PS Have you seen JISP?
