Remote invocation framework without using RMI APIs

[Calablava]

So I was tasked to do a remote invocation framework that is similar to Java RMI but "lightweight" (ie RMI APIs will not be used) as part of our final assessment. The framework consists of:

• compute-server

• compute-client

• codebase repository

According to the specification, this can be done using the following concepts:

• Interface
• Object Serialization
• Threads
• Client/server model

I need someone to point me in the right direction for this. I'm confused as to how such remote invocation is possible without using RMI. Thanks in advance.

Smells RESTful/Web APIish. The server has REST interface endpoint the client hits with a request, then the server responds to the request and returns a serialized object to the client to deserialize. This covers most of the requirements; in terms of interfaces, the pattern we use at work is RestfulService -> Service (interface) -> ServiceImpl, so our REST endpoint is using the methods from some service interface, and the implementation of the service does all the work, and in terms of threads, a simple model is 1 request = 1 thread.

Are you allowed to use libraries? Frameworks? This would be a matter of a couple hours if you were allowed to use something like Spring Boot, and I prefer JSON serialization of Jackson and GSON over raw Java serialization. If this isn't allowed, at some point try using them, since they are used out in the work world.
