Since its hanging during the Connect phase then the content-length property wouldn't come into play here since you aren't at the point of even sending or receive Stomp Send / Message Frames, the exchange at this point would either be the Connect / Connected exchange or a Subscribe if you are getting to the point of actually creating a Consumer. The content-length is optional in Stomp 1.0 for Send / Message frames and the frame must end in a newline either way so in that regards AMQCPP is stomp compliant. > > > Timothy Bish wrote: > > > > Can I ask why you need to use ActiveMQ-CPP to talk stomp to OpenMQ, > > don't they have a C client for OpenMQ? > > > > We already have an exisitng broker cluster of OpenMQ brokers, and we need a > C++ client to interact with them, but we also need it to use failover, which > their C client does not.
