Hi,

I am using MQTT Subscribe node as input and I have Java compute node next to it. and then finally I have one publication node which is going to publish message to other MQ subscriber. Now my question is. the publication node doesn't work! in my java compute i have already created the psc folder and include "publish" command and topic. at first, I noticed that. because I used MQTT subscribe node as input which means the message will not have any MQMD header, this maybe the issues cause the publication node doesn't work. So I added some MQMD header in my compute node. and after this. I can see the queue depth of my subscriber queue increased 1. however. when I browse the queue. there is empty message inside (then, I try publish message again. and the subscriber queue's queue depth increased 1 again. but.. still empty message inside again.). And then, I tried to use a stupid way. i added 1 MQ output node after my java compute and added 1 MQ header node after MQ output. and connect the MQ header to the publication node. and this way everything works fine. except I have to put the message in that MQ output... Can someone please tell me why my publication node doesn't work the way I want? and how can I solve the problem? I dont want to have that extra MQ output and MQ header node in my flow. please help me
