The principle of DWR:One, what is DWR?DWR: (Direct Web Remoting) is an open-source class library that helps developers develop Web sites that contain Ajax technology. It allows code (JavaScript) in the browser to use Java functions running on the WEB server as if it were in the browser .It consists of two main parts:A. Allow JavaScript to get data from a servlet (small application) that adheres to Ajax prin

If DWR is used, the effect is immediate. Although it may damage the MVC design pattern, its low-coupling programming method is as simple as developing a CS program. In the past, when I used ajax to write a program, the most time spent was the JS part. Now with DWR, I don't have to debug complicated JS and focus on the business logic, this will surely get twice the result! I just learned an entry-level insta

Background introduction: The project is a city credit Office system, before it seems to be a company in Shijiazhuang responsible. I belong to the halfway take over. After getting the source code, the project was set up according to the instructions they gave Jane (Shao) (de) Ming (ke) (lian). As a result, the project file is red. So we start to solve these mistakes, but many of them are similar. After some tinkering, most of the bugs were resolved, with a spring and

Matching Java objects with JavaScript objects Public Class Remote { Public void setperson (person p ){ This. Person = P; } } And classes person looks like this:Public person {Private string name;Private int age;Private date [] appointments;// Getters and setters... be sure to add getter and setter} // Then you can call this from JavaScript like this:VaR P = {Name: "Fred Bloggs ",Age: 42,Appointments: [new date (), new date ("1 Jan 2008")]};Remote. setperson (P ); Because setperson () is modifie
