webeans demo 2: Login

Steps to run demo2:

1. modify Login.java ( see below )
   
2. using ant to generate the anotations. ( when using Java 5, no this step)
   
3. compile it, hot-deploy it ( done by ide and framework runtime automatic)
   
4. retest it
   
5. ok, it will be improved than demo1

Features from this demo:

• webeans is POJO with metadata for extra information(we call model information)


• webeans is Model-Driven-Application without complex MDA tool, just using java to do the model

Login.java

public class Login{

/** @webeans.field length=16 maxlength=16 label="User Name" */
private String userName;

/** @webeans.field input=password length=12 maxlength=12 */
private String password;

.... getter/setter method ....

/** @webbeans.action */
public String login(){
// do login like
if( "admin".equals(userName) && "password".equals(password) ) return "Login Success"
else return "Login Failure";
}

}
