[xwiki-users] ERROR: XWiki 3.0M1 + Postgres + JBoss4.3 not working

Hi all, I'm trying to set up a fresh install of XE 3.0 on a JBoss 4.3 + Postgres 8.3 production environment. XE application deploys, but it does not start at all when I point the browser to it. The stack trace root cause is: "org.postgresql.util.PSQLException: ERROR: schema 'wikinf' does not exist". I've change the default database name from xwiki to wikinf, to attend our app names. I've set it properly in xwiki.db property from xwiki.cfg and, as well, in hibernate.cfg.xml file, on the postgres config section (jdbc:postgresql://<server>/wikinf), and I followed just exactly the Postgresql installation database creation instructions on Config pages from Xwiki.org. My database, called "wikinf", has nothing but the default public schema with the proper rights according to instructions (users and groups created accordingly). I'm using the postgresql-9.0-801.jdbc4.jar connector. Why it says the schema does not exist, if the database indeed exist, with the default public schema? I'm getting really annoying with this no-explication error, and could not find any instructions on Web. Could you help me please? Regards, Ramon Gomes Brandão
