Hi Dmitry
The entries for PostgreSQLPool that you have provided do not seem to
be correct. Can you send out these pool entries as they appear in your
domain.xml associated with your server.
The entries should be pointing to a valid postgresql database. Again my
suspicion is that the jdbc/PostgreSQL jdbc resource is not configured
correctly.
Let me explain w.r.t the postgres connection that I have set up here :
<resources>
<jdbc-resource enabled="true" jndi-name="jdbc/PostgreSQL"
object-type="user" pool-name="PostgresPool"/>
...
<jdbc-connection-pool allow-non-component-callers="false"
connection-validation-method="auto-commit"
datasource-classname="org.postgresql.ds.PGSimpleDataSource"
fail-all-connections="false" idle-timeout-in-seconds="300"
is-connection-validation-required="false"
is-isolation-level-guaranteed="false" max-pool-size="32"
max-wait-time-in-millis="60000" name="PostgresPool"
non-transactional-connections="false" pool-resize-quantity="2"
res-type="javax.sql.DataSource" steady-pool-size="8">
<property name="PortNumber" value="5432"/>
<property name="Password" value="postgres"/>
<property name="User" value="postgres"/>
<property name="serverName" value="postgres-machine-name"/>
<property name="DatabaseName" value="test"/>
</jdbc-connection-pool>
...
</resources>
I have copied the postgres client jar -
"postgresql-8.2dev-500.jdbc3.jar" into the application server lib
directory and restarted the machine.
The server works correctly i.e it connects to the database and also
creates the tables with the correct database field types.
Thanks
Pramod
