There are post about this.
Search with the "default" and "url" key words.
ho ho... I answered to quickly...
first level :
build your own pages, with the portal/windows/instances/portlet manager in the default portal.
or by defining it in the *.xml descriptor files.
second level :
if you want to define your own portal, with your own url etc...
and not have the default portal running on your server, then see the other posts....
Thank you Antoine,
I have my own default-object.xml definition into my war file, so I don't want to have to do that into the server descriptor.
I've been looking for that, but I haven't found a good answer. I'll continue researching.
Anyway, thanks a lot, I've written several posts without answers. It's great receive response from anyone.
