I had seen many new deveopers looking for jsf login example. So I decided to write a small example.
Below are the required libraries to run this example which are easily availabel
commons-beanutils
commons-collections
commons-digester
commons-el
commons-logging
jsf-api
jsf-impl
jstl
myfaces-all
standard
el-ri
el-api
The structure of the applictaion which I am following is (Eclipse IDE)
JSFLoginExample
|---src
| |----com
| | |----raj
| | | |----SimpleLogin.java
| | | |----LoginBean.java
|---WebContent
| |---WEB-INF
| | |---lib
| | |---faces-config.xml
| | |---web.xml
| |---login.jsp
| |---resultforfail.jsp
| |---resultforSuccess.jsp
It is true that different IDE's use different structure, but at last when war is build they follow same structure.
Lets start...
SimpleLogin.java
package com.raj;
/**
* @author nagarajuv
*
*/
public class SimpleLogin{
private LoginBean loginBean;
public SimpleLogin(){}
public String CheckValidUser(){
if(loginBean.loginname.equals("chandan") && loginBean.password.equals("chand")){
System.out.println("chandan");
return "success";
}
else{
System.out.println("Going to failure page");
return "fail";
}
}
public LoginBean getLoginBean() {
return loginBean;
}
public void setLoginBean(LoginBean loginBean) {
this.loginBean = loginBean;
}
}
LoginBean.java
package com.raj;
/**
* @author nagarajuv
*
*/
public class LoginBean {
String loginname;
String password;
public LoginBean(){
}
/**
* @param loginname
* @param password
*/
public LoginBean(String loginname, String password) {
super();
this.loginname = loginname;
this.password = password;
}
public String getLoginname(){
return loginname;
}
public void setLoginname(String loginname){
this.loginname = loginname;
}
public String getPassword(){
return password;
}
public void setPassword(String password){
this.password = password;
}
}
