Hi, most probably your have an hsqldb-jdbc2-state-service.xml file lying around in or beneath your deploy/ directory (probably deploy/jms). The SQL code it is failing on is the CREATE CACHED TABLE - so far as I know postgres does not support the CACHED keyword in this context. In my server.log (you should have the same indicator to the smoking gun here) : 2007-09-02 10:51:11,622 DEBUG [org.jboss.mq.pm.jdbc2.PersistenceManager] Could not create table with SQL: CREATE CACHED TABLE JMS_MESSAGES ( MESSAGEID INTEGER NOT NULL, DESTINATION VARCHAR(255) NOT NULL, TXID INTEGER, TXOP CHAR(1), MESSAGEBLOB OBJECT, PRIMARY KEY (MESSAGEID, DESTINATION) ) | org.postgresql.util.PSQLException: ERROR: syntax error at or near "CACHED" at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:1548) | ...<snip> | Don't ask me why this is different to the INFO log output which reports 10:51:11,634 WARN [ServiceController] Problem starting service jboss.mq:service=PersistenceManager org.jboss.mq.SpyJMSException: Could not resolve uncommited transactions. Message recovery may not be accurate; - nested throwable: (org.postgresql.util.PSQLException: ERROR: syntax error at or near "TXID") Kind regards, ROb View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080284#...
