Tree in a portlet
Hi!

Well, I think a jsp or a velocity portlet can work.
There are a lot of Java tree API available, and putting data into session
should be quite straightforward.
A jsp submitting a form to itself when clicking on an item could put the
item in the session, couldn't it?

See the example of the Portal Site manager, it works with a Tree :)

What I have is a tree structure of "products", a dynamic structure. I want
to show this structure for the user, and when the user selects
one I want to put that product in the session for other portlets to use.

A tree of what?
Maybe you can use a jsp portlet...
If you need an example, www.euroworksafe.org, click on Free Tour, then
OntoSafeBrowser.
It is a JSP/Servlet application shown through a IFramePortlet.
Cheers,
Stefano

Configure the dojo location in your desktop-theme:
djConfig.baseScriptUri =
de_jsessionid_url('$jetspeedDesktop.getPortalResourceUrl("/javascript/dojo/")'
);
djConfig.desktopThemeRootUrl =
de_jsessionid_url("$jetspeedDesktop.getDesktopThemeRootUrl()" );
<script type="text/javascript"
src='$jetspeedDesktop.getPortalResourceUrl("/javascript/dojo/dojo.js")'></script>

Oh, one more thing:
Is it easy to change the location of dojo.js? Hopefully it is a
configuration somewhere that only needs to be changed in the one spot?
The reason I ask is that I would prefer to host it on the web server
rather than the app server for performance reasons...

Ah, sweet. I'll look at what's done in AbstractDojoVelocityPortlet
and I'm sure I can figure out something for my specific case in the
mean time...

This solution could be better designed to work with JSP or any other
dispatched template. In fact, I think it should be refactored and more
formalized to a complete doHeader phase in the portal itself.
I look at this as a prototype we came up with for a need. Now we need to
refine the solution and align it with the upcoming standard.

The AbstractDojoVelocityPortlet uses the HeaderResource component to
ensure that any header resources added via addHeaderInfo or
addJavaScript or addStyleSheet are unique.

Re: Tree in a portlet
Posted by Aaron Evans <aa...@gmail.com>.
David,
I will take a look at that example for sure, however, I don't use
velocity in my portlets, so I'll have to figure out exactly what needs
doing for a portlet in general in order to join in the "doHeader"
phase.
One question I have though is how we prevent multiple portlets from
including the same resources multiple times? (Eg. if 5 portlets in
the page all need dojo.js, then how do we prevent it from being
needlessly included 5 times).
Perhaps this will become obvious when I look at the example, in which
case, disregard the question.
I use dojo heavily though, so I'm sure when I upgrade to 2.1, I'll
have a few things to figure out...

Dojo also has a tree widget
You can use Dojo in any portlet running in Jetspeed, either in /desktop
or /portlet. Take a look at the SecurityPermissionsPortlet.java for an
example of how to do this (and its vm, view.vm)
Important:
SecurityPermissionsPortlet extends AbstractDojoVelocityPortlet
You will need to extend AbstractDojoVelocityPortlet (just add a dep to
the jetspeed-gems jar)
This is necessary to join in the "doHeader" phase of the portlet request
cycle. Currently there are two cycles for a portlet request:
1. action
2. render
With JSR-286, there will be 3 phases:
1. header
2. action
3. render
The AbstractDojoVelocityPortlet handles the header phase
There are two methods to override for your dojo imports:
1. includeDojoRequires
2. includeDojoWidgetRequires
See the SecurityPermissionPortlet for examples of including in dojo
imports into the <head> area
All of this will get sorted out with the new spec
I really don't like that we have to include dojo imports via java
It would be much better via a vm or jsp file
But, this is where its at right now...
