My context.xml is quite straightforward.
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<Resource name="jdbc/postgres"
override="true"
auth="Container"
type="javax.sql.DataSource"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://SERVERNAME:5432/Dionysos"
username="FOO"
password="BAZ"
maxActive="20"
maxIdle="10"
maxWait="1000"
removeAbandoned="true"
removeAbandonedTimeout="15"
logAbandoned="true"
validationQuery="SELECT 1"/>
</Context>
I put it in the META-INF folder of my WAR.
But be advised: If you think you can change the url/username or passwd once the
app has been deployed in Catalina/localhost/WEBAPPNAME.xml it will NOT work.

OK, thanks, what does your context.xml look like for the jdbc/progress?
