. Well i answered based on the exception you were
getting...java.io.FileNotFoundException: localhost:80//servlet/DbServlet
. but if the problem is with the inputstream that the servlet reads
from the applet...i really suggest you to use the class that Jason Hunter
developed in his Servlets book....it's called HttpMessage..it's really
useful and you dont' have to hardcode the Streams objects...you can find it
at www.servlets.com i think it's chapter 10 Applet-SErvlet Communicatoin....
. hope this helps,
. javier.
