 Very strange error, never seen that before (in Jigsaw servlets). 
 does it happens with every servlet? Did you test these servlets with
 the servletrunner? Which jdk are you using? Can you give me more 
 details?

 What is a servlet file? is it the class file? I'm not sure to understand
 your question. 
 You can configure it by hand, but you can also create a servlet 
 indexer.

 Yes you can configure an indexer in order to index all .class files 
 to a ServletWrapper (with a servletWrapperFrame). see [1]

 Yes, but you can create a cgi-indexer that create a 
 FileResource+CGIFrame for each file in WWW/cgi-bin (see [1])

 BROWSE is a special method of aolpress brother, not really useful.
 Don't take care about that.
