Thanks to all of you who offered advice before: I'm now a bit more confident that this can be made to work. I'm still using JDK 1.4, JBoss 3RC1, Postgres 7.2.1 and the pgjdbc2.jar driver on Linux and I now have a "PostgresDS" appearing in my list of MBeans. I've bound this to the JNDI name "DefaultDS" in the "postgres-service.xml" file and removed the corresponding db-service.xml file for hsql.
JBoss now appears to start up cleanly, but as soon as I copy my ".ear" file to the deploy directory, I get a string of Exceptions being thrown. The first of these appears to be the most serious, and the reason why the later exceptions are thrown: 2002-04-16 13:10:25,422 DEBUG [org.jboss.ejb.plugins.jaws.jdbc.JDBCCommand] Load SQL: SELECT OSUser.id,OSUser.passwordHash,OSUser.name FROM OSUser WHERE id=? 2002-04-16 13:10:26,052 ERROR [org.jboss.resource.security.ConfiguredIdentityLoginModule] The ConnectionManager mbean: jboss.jca:service=LocalTxDS,name=PostgresDS specified in a ConfiguredIdentityLoginModule could not be found. ConnectionFactory will be unusable! 2002-04-16 13:10:26,114 ERROR [org.jboss.ejb.EntityContainer] Exception in service lifecyle operation: create java.lang.SecurityException: Invalid authentication attempt, principal=null at org.jboss.resource.connectionmanager.BaseConnectionManager2.getSubject(BaseConnectionManager2.java:542) So it looks like in the postgres-service.xml file, I need to specify a different ConnectionManager. Anyone out there know which one?
