I'm experiencing problems with the portal CMS. After exporting content or copying content the exports or copies completely lack mime type information. It is completely impossible to change or delete reimported or copied content. Our backend database is Oracle 11g (and I inserted a driver entry in every hibernate.cfg.xml file I found). For now we can live with completely reinitializing our database but when we are going in production state this is no solution. Perhaps there is another configuration for Oracle I don't know about? The export/import problems didn't occur with JBossPortal 2.6.7, but we had the problems with JBossPortal 2.7.0 and now 2.7.1 as well.
