I had "JBossPortal 2.2.1RC3+JBoss AS bundle" installed on Linux Debian, behind an Apache web server, and using PostgreSQL 8.1.3. It worked fine !
I've installed "JBoss 2.2.1 SP1+JBoss AS bundle" to fix some problems, and now I see the JBossPortal pages with no decoration, and no pictures at all ! It seems there's no theme, no layout, and no pictures (except the pictures of the default page : jboss_logo.gif, support.gif, plugin.gif and project.gif). Don't see any pictures of the themes, even if I change it.
I have no errors on the log (just one that I had before : "Locale name null or empty, ignoring"). That's all !
The database seems to be ok : I can see the records in the PostgreSQL tables...
