Unfortunately, it seems Struts doesn't have any further component for
more than two selects (3, 4, 5, ... n dependent selects). However, you
can use java-script as advised (Strut's doubleselect also generates
java-script for client). Or more harder but nicer and cleaner, you can
review current Strut's doubleselect implementation and see if you can
improve it to accept N sequentially dependent selects! Then you can try
a share/merge into Struts :)
