JSON-RPC-Java provides an RPC implementation that allows JavaScript DHTML Web applications to call remote methods in a Java Application Server (AJAX functionality) without the need for page reloading. It is an enabler for the next generation of fast and highly dynamic enterprise Java Web applications. Minimal changes (if any) are necessary to existing server-side Java code to allow calling from JavaScript (such as the marshalling and unmarshalling of special types), as JSON-RPC-Java dynamically maps JavaScript objects to and from Java objects using Java reflection.
