<jndi-name>DefaultDS</jndi-name>
<connection-url>jdbc:postgresql://localhost:3306/istraining</connection-url>
<driver-class>org.postgresql.Driver</driver-class>
<user-name>root</user-name>
<password>password</password>
<!-- sql to call when connection is created. Can be anything, select 1 is valid for PostgreSQL
<new-connection-sql>select 1</new-connection-sql>
-->

<!-- sql to call on an existing pooled connection when it is obtained from pool. Can be anything, select 1 is valid for PostgreSQL
<check-valid-connection-sql>select 1</check-valid-connection-sql>

I am slightly confused. You claim to be using JBoss AS 4.2.3, but then mention placing the JDBC driver JAR files in common/lib which is a JBoss AS 5.0 directory. Which version are you really using?

Your *-ds.xml files looks OK to me, nothing obviously wrong. But the settings you have given must be incorrect because PostgreSQL doesn't like them. Try running the pgsql client, connecting to the istraining database using the user-name and password given in the *-ds.xml file.

I also googled and found this: http://archives.postgresql.org/pgsql-general/2007-04/msg01210.php. Seems there could be a bug in the driver. Perhaps try a different driver version. I know that I have had success with postgresql-8.3-603.jdbc3.jar
