Hi,
In a portal, we must integrate an application doing a search then
showing a result page.
This application should be implemented as a portlet.
Assuming we have 3 pages in the portlet:
Page 1: Simple search: a form with a single text field, whose action
is launching a search, this page contains also a link to Page 2 who
corresponds to Advanced search.
Page 2: Advanced search: a form with multiple fields, whose action
is also launching a search.
Page 3: list of results, who is used for displaying results of Page
1 and Page 2.
On the portal's permanent menu, a small region shows always the Page
1 (Simple search).
The central zone of the portal initially shows information from
other portlets.
When one click on the link of the Page 1, the central zone of the
portal must display the Page 2 (Advanced search).
When one type a name and submit the form of the Page 1 (Simple
Search), the central zone of the portal displays the Page 3 (List of
results).
When one type in information and submit the form of the Page 2
(Advanced search), the central zone displays the Page 3 (List of
results).
Beeing new to portlet, I've quite a few questions:
1) should Page 1 be defined as a portlet and the central zone as
another portlet ?
This is a hard one to answer, as it depends on your user requirements
etc. I have implemented a search form for a medical database search
application. In that case, I think I made the advanced search expand
out in a hidden div.
Its really up to you
2) if so, both portlets can be the same war ?
yes, of course
3) how can I show the portal page containg Page 2 (Advanced Search)
when I click on the link inside Page 1 (how to specify the good URL
inside my JSP) ?
you can make a link to a page by hardcoding it "/jetspeed/portal/
advancedSearch.psml"
4) is similar to 3), how can I trigger processAction() of my portlet
when submit the form from Page 1 (Simple Search) and at the same
time instruct the portal to switch to the page containing the Page 3
(List of results) ?
You have to send back to your own portlet for the processAction(), and
then redirect to Page 2 using the portlet api in your processAction.
The portlet api disallows calling the process action of another
portlet from your portlet (on the current or any page)
I usually do this with a redirect in the action such as
response.sendRedirect("/jetspeed/portal/search.psml");
