1. Advantages of dwr compared with ajax ..

Dwr is built on ajax .. More dsl-based ..

It greatly simplifies the workload of compiling ajax.

2. working principle of DWR

The Java class is generated as Javascript dynamically. Its code is like Ajax. you feel like calling occurs on the browser side, but actually code calling occurs on the server side. DWR is responsible for data transmission and conversion. This remote call function from Java to JavaScript enables DWR to use a common RPC mechanism like RMI or SOAP, the advantage of DWR is that it can run on a webpage without any web browser plug-ins.

Java is basically a synchronization mechanism, but AJAX is asynchronous. So when you call a remote method, when the data has been returned from the network, you need to provide DWR with the callback function.

DWR places an engine. js on the client as the client engine, and a dwr. jar on the Server as the Server engine.

Then, it can be described in RPC mode.
