Alternatives to RMI for IPC?


I have 2 processes that need to communicate over the same PC and different PCs. In the local case the process communication is among different processes e.g Process A and Process B.
In the remote case it will be among 2 instances of Process A running in different PCs.
I will create them from scratch and I am wondering what is the best approach. I am aware of RMI and sockets but I was wondering for my case as described, and taking also into account that the messages exchanged are small and the number of APIs really small, if there is a standard approach/library for this.
Any suggesstions are highly welcome

Update after @EJP comments:
My interest is 1)to implement the requirement for communication in a light manner since the API exposed will be really small and the messages as well 2)use and learn a new popular framework if possible (I already know RMI and sockets)


Solution

  • If you are just looking for messaging frameworks, there's a bunch available out such as

    But when you use a 3rd party framework, you are then adding an additional dependency to your application. If it is something very simple like your case, perhaps writing a TCP client/server would be sufficient for a client/server paradigm or if you are looking for publisher/subscriber paradigm then you can look into using UDP multicast. You just need your data class to extends Serializable if you want to be able to marshal and unmarshal your data to buffer and send it over to network using typical JAVA socket API.
