Thank you for your response. I did actually find the getText() and
setText() methods before writting this, I was just a little unsure as
to how to implement them. the URL feature is an essential element of
the program I am trying to write. Since I can't do this with GWT and I
can't do this using an applet either (applets can only connect to the
same server as well i believe), I think I have hit a dead end. What
other options do I have? What do you recommend I use to create this
type of web application?
Thanks for your help.
