#  Usage:
#     First cd to the directory you want to search, the current directory
#     and sub directories will be searched for jar files.  Each jar file will be
#     checked.  When an interesting jar is found, the directory will be printed
#     first, then all the interesting jars.  For each interesting jar, every
#     matching class will be printed as a fully qualified name.
#
#     	(A)  	looking for a class name that ends in ServletResponse:
# 			findj.sh ServletResponse
#
#	  	(B)  	looking for an exact class name 
#          		(prefix with a [/]):
#         	findj.sh /HttpServletResponse
#
#     	(C)  	looking for all classes in a package name, 
#				ending in 'servlet.http' 
#				(add the suffix [.*]):
#         	findj.sh servlet.http.*
#
#		(D) looking for all classes in a fully specified package name
#				(add prefix [' ] and suffix [.*']):
#			findj.sh ' javax.servlet.http.*'
