Well, it's tough to help you with your code when you paste the "wrong" thing and say it doesn't work. If you haven't read the guide yet, please do so. There is a chapter on customer request/reply routing using ROUTER/DEALER sockets. There was a Java code example attached to part of it that you can read here: http://zguide.zeromq.org/java:rtdealer This is the same code example you posted above. If it isn't working, then please tell us what kind of error it is producing or what behavior you see. If it *is* working, then please explain what part of it confuses you. At this point, I'm curious to know if you are using 2.1.10 for testing or if you are using 3.03 for testing. In 3.x, the API changed such that XREQ/XREP are no longer synonyms for DEALER/ROUTER, so connecting the two of them may or may not work since the routing envelopes are handled a bit differently. There was a recent thread started on this topic (within the last week). cr
