How to set MQ headers using JSR223 sampler in Jmeter - jmeter

Question

I am working on IBM MQ testing. I able to inject my payloads request in MQ destination. I need to put the headers values in MQ to get the correct response. I used various option but still i am unable to put headers values in MQ server. Kindly let me know how can i solve this in JMeter.
Option 1 :
sendmsg = new MQMessage();
sendmsg.setStringProperty("QueryName", "GetPortfolio");
sendmsg.setStringProperty("Country", "LV");
Option 2:
rfh2.setFieldValue('usr', 'QueryName=', 'GetPortfolio')
Option 3:
SampleResult.setRequestHeaders("QueryName=GetPortfolio")

Answer 1

Option # 1 is the correct way of doing it.
Option # 2 could be used but why? And the parameter should not include the equals sign ( i.e. "=").
I have no idea what option # 3 is.
Here is a sample Java/MQ program that puts a message on a queue with named properties .

When I look at the message in the queue with MQ Visual Edit, I see:
So, your 2 named properties are with the message.
The question becomes do you want JUST named properties attached to the message or are you really looking to create a JMS message with named properties?
Note: A JMS message is internally defined as an MQRFH2 message. i.e. JMS message ==> MQRFH2 message but the opposite may not be true.
Hence, if you want a JMS message with named properties then you need to uncomment those 3 lines in MQTest11P.java above.
i.e.
sendmsg.setStringProperty("mcd.Msd", "jms_text");
sendmsg.setStringProperty("jms.Dst", "queue:///"+outputQName);
sendmsg.setStringProperty("jms.Pri", "0");
