Connecting Java Application to Ruby on Rails SQLite3 Database -

I am currently working on an electronic gradebook which allows the user to store students and grades in the Java desktop application, among other things. I want to be able to send that information to the Ruby on Ruby SQLite3 database through a stream on the Internet. The purpose of this is that students can use the Ruby report related to their grades on Rail application. Ia ???? I am hoping to make the connection as simple as possible in both Java and Rail applications are mostly complete (although the Rail SQLite3 database is required to be normalized). The problem is that I do not have the experience of connecting applications and I'm not getting any information specifically to connect to a Java desktop application on Ruby on the Railway SQLite3 database. If I can get an example or book that works specifically with him, then it will be something to do the work. So far, my understanding, which is very common for me to do anything, is that I might have another API And should use JSON or JRUB. My rail application has been made mostly already, so I really want to be with the standard rail if someone can tell me an example of doing one thing or provide some information, I would be grateful.

Your Java app should be in the Rail app, on the railway side, you can find it similar to another type of request Can keep If you need to get data from the Rail app, then the concerned railways will need to return the data in your Java application format, and in nearly every language there are already written libraries to parse JSON.
