Paul:
Something like this may work; we have a similar logic working elsewhere (on
code we control).
As I understand your question, two implementations are possible. Both assume
knowledge of external html Form source code.
FIRST IMPLEMENTATION: Automate form default values for user input.
We use code that allows us to fill-in forms that we control. The logic
seems applicable to any form code, following something like this pseudo
code:
1) JSP/Servlet opens second page url; reads source into local String
var, say strVar.
2) Look for input vars (find strVar.indexOf( somevarname )
3) Find positions of related html <input> tag (index of nearest < and >
tag delimiters)
4) replace entire <input ...> tag with a <input name=... [value] >
string for somevarname
5) send strVar as response to client
SECOND IMPLEMENTATION: Automate second Form POST from first Form data (does
not require user input).
(This would be like having form ONE capture information to be posted so
an external server, say as an automatic submission to Yahoo.com, for
example.)
Simply create hidden html form with the new data and post it to the
external form server... (I think Real Gagnon
(http://tactika.com/realhome/realhome.html) discusses Post to a url. If not,
someone else here has posted information on how to do it -- check the
archives.)
Your choice of languages for either of these implementations; Java is my
preferred choice -- much easier to do in Java than in C and I think
performance is comparable. ( Zhu Jiang suggested JavaScript; don't know if
his idea is plausible and can find no reason to use client side technology
in this application. Besides, this is a server side technology group ;-)
If you need help or an example, let me know.
Good luck.
Phil
