I am using the following:
URLConnection uc = url.openConnection();
uc.setDoOutput(true);
I've not had any problems with it using the doPost() method in the servlet.
I think it's probably a matter of the correct connection parameters when I
run the web page which has the applet button on it. This starts up the
applet and from there, I'm not sure what I need to specify for the
connection to work and debug into the servlet running in the VisualCafe
environment. Somehow, I (mentally) can't make the picture work as to how the
connection is made from the applet to the servlet that I have started and
running in the VisualCafe environment in the debug mode, and physically it
doesn't work either. I know on the purely html post page, it is post like
<form action=http://demo:8080/servlet/survey method=POST> and this works
fine.
Does anyone have any ideas on the specific connection info here?
Thanks,
Gary
