title: Alternatives to RMI
body: <p>I have a small Java SE application, it´s practically a fat client sitting on top of a database. To further my Java skills, I decided to make a client-server application out of it. The server application communicates with the database and handles all kinds of lengthy operations, while the client application only receives the results, mostly ArrayLists of moderate length and primitives. </p>
  
  <p>To this end, I started reading on RMI and did the Oracle tutorial, which I found surprisingly difficult to understand and even get to work.</p>
  
  <p>Is there anything else I can use instead of RMI, without having to dive into JavaEE? </p>
