Thanks very much for AMQ CPP. Our legacy system using the stomp library from http://stomp.codehaus.org and write stomp frame to socket directly.
The impls of commit and abort are "COMMIT" and "ABORT" in the stomp frame header. With regards to "ABORT", the message acknowledge are abort and MQ broker still keep this message. We expect on the next call of stomp_read, MQ broker deliver this pending messages. However it does not unless reconnect and subscribe to the queue. Is there any header attribute or configuration to let pending messages redeliver on the next call stomp_read ?
