Hi,
I am trying to run the sample code from Willy Farrell's article http://www-106.ibm.com/developerworks/ibm/library/i-ad5mq53/,
I installed the Websphere MQ 5.3 and setup it up as the article said, also had all setup in WSAD 5.1, and run the
QReceiverUI, then put mq/MyQCF in the Connection, it give this error:
Exception: javax.naming.ServiceUnavailableException: Could not obtain an initial context due to a communication failure. Since no provider URL was specified, the default provider URL of "corbaloc:iiop:1.0@99b41p4:2809/NameService" was used. Make sure that any bootstrap address information in the URL is correct and that the target name server is running. Possible causes other than an incorrect bootstrap address or unavailable name server include the network environment and workstation network configuration. [Root exception is org.omg.CORBA.UNKNOWN: minor code: 0 completed: Maybe]
any idea?
Thanks.
David

Make sure you are using Embedded Messaging and not MQJD. This is explained here:
