Response not received in jmeter.

[Vishwa119]

I am sending a request to a switch with header and no trailer. I am using log channel because i dont need any length bit at start, no trailer or padding at end. I can pack and send req to switch and able to receive the succcessful response from switch , which i can see in wireshark. but Jmeter iso8583 plugin couldnt receive it , hence its getting timeout. Also no issue beinglogged like issue in unpacking any fields. Seems all that are okay. I tried using differernt channels and same is the case. Even tried adding MTI mapping, mux configuration. No Success. What could be the issue.



i have put a mock server to test

Wireshark dump:
port 12015 is the mock server

My Observation:
when Req having field 41 and if response doesnt have field 41 , then response is not received ( Concern !!)
Additionally , When log channel is used , then response is not received

Appreciate if any input on this.. can DE 41 be bypassed if its an expected behaviour or is it a bug.. please assist in overcoming this..Thanks in Advance!

@Vishwa119

1. Don't use LogChannel.
2. The MTI Mapping is wrong. Remove.
3. If DE41 is not present, the Mux Key Configuration needs to be defined as above with e.g. 11 37.
4. Try again.

Yeah its working Now..Thank you .. But only log channel mimics the message i am having.. without any length bit, trailer , header in ascii... Any way to add custom channel ..

If you look at what LogChannel does ("Extracts <isomsg> blocks from standard jPOS log") you'll find it is almost certainly not what you are after.

You can of course implement your own custom channel class, by extending BaseChannel, though I would recommend you double check that none of the standard channels work.

Are you sure there is no length prefix? Have you confirmed that via a Wireshark trace from your actual switch and/or your messaging specification?
