i am trying to access MQ queues using JMS. i am getting the below
java.lang.UnsatisfiedLinkError: no mqjbnd05 in java.library.path
i am passing
-Djava.library.path="C:\Program Files\IBM\WebSphere MQ\java\lib"
as the VM argument while running the program in eclipse. This issue is discussed quite a lot on the net but with out any conclusion. Has anyone resolved this? TIA.
Answer
As I had to deal with this error myself; and it took me a lot of time to find the right answer, I'd like to share it with the next one, who comes along this thread...
Actually the solution to the problem was very simple (at least in my case). It was not related to any CLASSPATH, java.library.path or installation issues.
I simply forgot to switch the MQConnectionFactory into the Client mode.
This has to be done, by simply calling
cf.setTransportType(WMQConstants.WMQ_CM_CLIENT);
or
cf.setTransportType(WMQConstants.WMQ_CM_BINDINGS_THEN_CLIENT);
or any other connection type, that fits your needs.
By default, the ConnectionFactory is in "Binding" mode (WMQ_CM_BINDINGS), which is intended for local server installations, as it is is stated in the IBM Documentation:
To connect to a queue manager in bindings mode, a WebSphere MQ classes for JMS application must run on the same system on which the queue manager is running.
This transport type is the same as the XMSC_WMQ_CONNECTION_MODE (WMQConstants.WMQ_CONNECTION_MODE) property, when using JNDI or the JmsFactoryFactory.
The same should apply to the other ConnectionFactory types: MQQueueConnectionFactory, MQTopicConnectionFactory, MQXAConnectionFactory, MQXAQueueConnectionFactory and MQXATopicConnectionFactory
Check the IMB Knowledge Center for more information about the different connection/binding options:
