A library for a simple integration of the JSON-RPC 2.0 protocol to a Java application.

The motivation of this library is to provide a simple, fast and reliable way to integrate the JSON-RPC 2.0 protocol into your application at the server or client side. For that you need to configure either JsonRpcClient or JsonRpcServer and implement transport code - the library takes care for the rest. No manual JSON transformation, reflection code, error handling - just a service interface with annotations. Even this is not a requriement - there is a fluent API at the client side if you like DSL builders. The library is a full-compilant JSON-RPC 2.0 protocol implementation, so it should handle all kind of JSON-RPC requests (correct or mailformed). It doesn't depend on any transport protocol, an application server, or a DI library.

The library has a few dependencies:

• Jackson, which is great for JSON parsing and databinding;
• Guava, which is great for caching and optional values (needed only for server)
• SL4J, which is the standard for logging (needed only for server)
• IntelliJ Annotation, which is great for providing compiler-time null checks.

• Client

• Server
