I finally got jboss 3.0.2 to work with CA-Ingres and the Caribou Lake JDBC driver. I copied the docs/examples/jca/postgres-service.xml file, which seemed to work. Here's my ingres-service.xml:

<!-- ************************************************ -->
<?xml version="1.0" encoding="UTF-8"?>

<!-- ======================================================================================== -->
<!-- New ConnectionManager setup for default PostgreSQL dbs -->
<!-- Build jmx-api (build/build.sh all) and view for config documentation -->
<!-- To avoid class not found headaches, copy your postgres driver to the jboss lib directory -->
<!-- ======================================================================================== -->




<!-- ======================================================= -->
<!-- You must include a login module configuration named PostgresDbRealm
in your login-conf.xml, here is an example for a
ConfiguredIdentityLoginModule:

<application-policy name = "PostgresDbRealm">

<login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule" flag = "required">
<module-option name = "principal">yourprincipal</module-option>
<module-option name = "userName">yourusername</module-option>
<module-option name = "password">yourpassword</module-option>
<module-option name = "managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=IngresDS</module-option>
</login-module>

</application-policy>

NOTE: the application-policy name attribute must match SecurityDomainJndiName, and the
module-option name = "managedConnectionFactoryName"
must match the object name of the ConnectionManager you are configuring here.
-->
<!-- ===================================================================== -->
<!--uncomment out this line if you are using the PostgresDbRealm above
PostgresDbRealm
-->
