BEA Weblogic Interview Question:

I configured the messaging bridge to use the Exactly-once quality of service for two-phase transactions. So why am I getting a quality of service is unreachable error?

There are some additional configuration requirements for the messaging bridge to handle transactions between WebLogic domains:

* The supported adapters are located in the WL_HOMElib directory. For the Exactly-once QOS, the transaction adapter, jms-xa-adp.rar, must be deployed in the release 6.1 domain where the bridge is running, via the select Deployments -> Applications node on the console.
* This jms-xa-adp.rar adapter must also be identified in the Adapter JNDI Name attribute as eis.jms.WLSConnectionFactoryJNDIXA on the JMS Bridge Destination -> Configuration tab for both the source and target bridge destinations.
* For WebLogic JMS, verify that you are using the transactional XAConnectionFactory for the queue or topic destinations mapped to both the source and target bridge destinations. To verify this, the following attributes must be set on the JMS -> Connection Factory -> Configuration -> Transactions console tab or in the configuration file (config.xml):
UserTransactionsEnabled=true
XAConnectionFactory=true
* For third-party JMS vendors, verify that you are using a transactional connection factory for the destinations mapped to the source and target bridge destinations.
