Thanks Phil,
I implemented something similar to your first suggestion and used javascript
form.submit() to submit the form.
This seems to work well - with two slight issues .....
(1) It works fine for the first form, but if I want to fill in multiple
forms in sequence (such as doing a registration or soemthing) then it
becomes a problem - because the first form needs to keep control throught
the whole process.
i.e if test.jsp is the first form ... it needs to
--- get form1.htm
--- prefills and submits form1.htm
--- parses the response ...
--- get form2.htm
--- prefills and submits form2.htm
--- parses the response ...
--- get form3.htm
--- etc ...
the problem is that as soon as the form is posted the result is returned to
the browser and test.jsp no longer has control. Is there anyway to avoid
this?
(2) In testing I have actually been reading and posting forms on a local
server. I just tried to auto post some forms to external (internet) servers
and I'm having problems ... the request for the page timesout and throws a
"NoRouteToHostException" which I think is because it cant find it way
through the firewall. How can I setup the URL connection to go through the
firewall?
