Hi Peter I'm building JBossAS from trunk (latest) source and I get my postgresql-persistence-service.xml from thirdparty/jboss/messaging/resources I really don't see how the version of the file matters considering the error. It can't find MOVE_REFERENCE which is in the file. But it can't find it because it JDBCSupport.java never loads the statements. Check these snippets : how could it ever work - for any database? | protected Map getDefaultDMLStatements() | { | return Collections.EMPTY_MAP; | } | | protected Map getDefaultDDLStatements() | { | return Collections.EMPTY_MAP; | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127639#...
