MQSeries.net :: View topic - Simple Java application fails with 2058

sebastian · Posted: Fri Dec 31, 2004 10:08 am Post subject:

I am trying to run a simple MQ java application from page 73 of the WMQ Using Java manual. The program compiles okay but when I try to run it, I get an error of 2058 - qmgr name error. The queue manager name looks correct to me. Our queue manager is named PR01U64D and this matches the java code.

Code attached:

I know that with some other Perl MQ scripts I wrote, I needed to define the MQSERVER set to a server connection channel. Do I need to do something similar with this code as well?

any feedback is appreciated,
Sebastian
