Is there anyone out there that has succeded in putting a tree structure

What techs did u use?

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...
