Hi Nic:
Thanks for your reply.
First of all I will give you some information about my project, my prject
involves B2B integration between two sites using a third party called
iMediation. The only part which we have to implement is "Add to Bag". Lets say
site1 is primary vendor and site2 is secondary vendor, since both are having
B2B relation, site1 allows customer to do shopping of site2 from their site.
Initially customer will come to site1 and if he requests a product which is
available in site2, then site1 will simply redirect to site2. There user can
selects any product and if user clicks "Add to bag", it should add that product
in site1 cart.
Now my requirment is that, after performing "add to bag", my program should
return to site1 and additonally display a popup window saying "This item has
been added to site1 cart".
- Site2 will pass the url as parameter which will act as return path.
In order to simulate this, I am having two servlets which will perform this
process, you may assume that servlet1 and servlet are in two different
domains..
Now your first question:
>When you say "calls" I presume you mean that:
> - the submit goes to servlet1
> - servlet1 gets a RequestDispatcher for servlet2
> - servlet1 forward()s the request to servlet2
No, when I say "calls", the submit directly calls "Servlet2" since its
specified in <Form action>.
Servlet2 is getting RequestDispatcher for Servet1
Servlet2 forward()s the request to Servlet1
Your second question:
>1. Before redirecting to servlet 1, servlet 2 should produce html which will
display a popup window.
No, since the control is in servlet2, it should return to servlet1 but
addionally displays a popup window.
Now regarding forward(), if Servlet2 is forward()s to Servlet1, then what
should be the url in the browser, I am seeing the url for servlet2. This result
is same for both include() and forward().
Thanks,
Sushil
