using the latest postgresql jdbc jar (http://jdbc.postgresql.org/download/postgresql-9.2-1002.jdbc4.jar) I tried to configure a jdbc connection pool.
resource type of javax.sql.DataSource
database driver vendor: postgresql
introspect: not checked.
On the next page (after clicking 'next') I was presented with the usual suspects in terms of additional properties, and I populated these:
and hit 'finish'
the admin gui reported that the ping had failed.
I then checked the additional properties page, and found that only the 'user' value appeared.
I found that this was the only value for this connection pool that was present in the domain.xml file.
