We have an EAR which contains a connector module and an EJB. This worked fine in 1.0. Now while migrating to 1.1, we put the geronimo-ra.xml file in the connectow META-INF to configure the data pool. But when we deploy the EJB now, we get the follwoing error: Geronimo Application Server started Deployer operation failed: Unable to resolve resource reference 'orcl_ds' (Could not auto-map to resource . Try adding a resource-ref mapping to your Geronimo deployment plan.) org.apache.geronimo.common.DeploymentException: Unable to resolve resource reference 'orcl_ds' (Could not auto-map to resource. Try adding a resource-ref mapping to your Geronimo deployment plan.) where 'orcl_ds' is the name of the data source. we have entries both in the openejb-jar.xml and ejb-jar.xml, which worked in 1.0.
