The simple bean on JOnAS A needs to connect to its local JORAM server and access the remote queue. The following is an example of consistent resource definitions in the deployment descriptors:
Standard deployment descriptor:
<resource-ref> <res-ref-name>jms/factory</res-ref-name> <res-type>javax.jms.ConnectionFactory</res-type> <res-auth>Container</res-auth> </resource-ref> <resource-env-ref> <resource-env-ref-name> jms/sharedQueue </resource-env-ref-name> <resource-env-ref-type> javax.jms.Queue </resource-env-ref-type> </resource-env-ref> |
Specific deployment descriptor:
<jonas-resource> <res-ref-name>jms/factory</res-ref-name> <jndi-name>CF</jndi-name> </jonas-resource> <jonas-resource-env> <resource-env-ref-name> jms/sharedQueue </resource-env-ref-name> <jndi-name>scn:comp/sharedQueue</jndi-name> </jonas-resource-env> |
The ConnectionFactory is retrieved from the local JNDI registry of the bean. However, the Queue is retrieved from the distributed JORAM JNDI server because its name starts with the scn:comp/ prefix. It is the same queue to which the Message-Driven Bean on JOnAS B listens. To do this, its activation properties should be set as follows:
<activation-config> <activation-config-property> <activation-config-property-name> destination </activation-config-property-name> <activation-config-property-value> scn:comp/sharedQueue </activation-config-property-value> </activation-config-property> <activation-config-property> <activation-config-property-name> destinationType </activation-config-property-name> <activation-config-property-value> javax.jms.Queue </activation-config-property-value> </activation-config-property> </activation-config> |
