No that is not what I mean. It is just I still have no idea of what u r
doing. Do you mean that program is:
1. a CGI residing on some webserver
2. that is just a stand-alone program you can borrorw (this stand-alone
program will do all the interface for you, you just need to grab stuff from
standand input/output
3. or that is some server program listen on some port?
for 1, anything will do, you can use Socket to get it direcly or URL class
for 2, Runtime.execute
folr 3, use Socket to do the job.
Servlet and JSP are basically got the same functionality, whatever you can
do with servlet you can do with JSP. not much difference, except in JSP it
is more convient to put html text (but if you want to be able to support
foreign langanuges as well, JSP and servlet has no differences at all then.
Cause everything will be ResourceBoundles).
