What are some architectural solutions that can mimic eventing for systems (Java) that are too old to implement eventing solutions, such as conventional Queue/Topic based JMS messaging?
I have a system that is REST capable and needs to interface with other systems, but having it send messages would be the most ideal solution. However, it is too old to do so.
Are there any kind of architectural patterns/solutions that can provide capabilities like this?
Like perhaps some kind of framework which can act as a system in the middle, by fetching data from the legacy system over REST, then packing it into a format that's then sent over JMS?
