Unable to read from Java MQ Queue in Unix

Question

Hi,
I developed a small application that uses a scheduler as an input to a jcd. Once invoked, the jcd reads from a Java MQ queue and writes the result to the log.
I developed the application on CAPS 6 in Solaris 10.
We are however unable to read from the queue in Unix. The code returns an empty queue, even though the queue does have messages in it. Below is the code in the jcd used to read from the queue:
int recCount = 0;
+while (true) {+
com.stc.connectors.jms.Message txtMsg = JMS_1.receiveNoWait();
+// break out of loop, if no more messages+
+if (txtMsg == null) {+
logger.info( "Record Count is :: " recCount );+
break;
+}+
recCount+;+
+}+
The same project, imported into CAPS 6 on a Windows platform, works without issue.
Has anyone experienced compatability issues like this with Java MQ between Windows and Unix?

This is probably coz of the JMS header.
Try setting MQJMS_CLIENT_NONJMS_MQ as the target client and also try retrieving the message as ByteStream rather than TextMessage.
