These are the files:

test.jsp (which gets open when I access test.faces)
--------
 
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> 
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> 
<html> 
<body> 
<f:view> 
    <h:form >
<h:outputText value="Enter username (between 3 and 15)"/> 
<h:inputText id="username" value="#{LoginBean.username}" required="true"> 
        <f:validateLength maximum="15" minimum="3" /> 
    </h:inputText> 
    <h:message for="username" />
<h:commandButton id="submit" action="#{LoginBean.login}" value="Login" /> 
</h:form>
</f:view> 
</body> 
</html>

LoginBean.java
--------------
 
package jsflogin;
 
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
 
public class LoginBean {
 
String username;
 
public String getUsername() {
return this.username;
}
 
public void setUsername(String data) {
this.username = data;
}
 
public String login() {
if (username.equals("james")) {
System.out.println("success");
return "success";
} else {
System.out.println("failure");
FacesContext context = FacesContext.getCurrentInstance();
FacesMessage message = new FacesMessage("username is wrong");
context.addMessage("loginForm", message);
return "failure";
}
}
}

faces-config.xml (to avoid any error, I am providing navigation rule for both test.jsp and test.faces)
-----------------
 
<?xml version="1.0"?> 
<!DOCTYPE faces-config PUBLIC 
  "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"

         </navigation-case> 
    </navigation-rule>

        <managed-bean-scope>session</managed-bean-scope> 
    </managed-bean> 
 
</faces-config>

            <url-pattern>*.faces</url-pattern> 
        </servlet-mapping> 
  
</web-app>

greeting.jsp and greeting.faces (why two...again to avoid error)
-------------------------------
 
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> 
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> 
 
<html> 
  <head> <title>Greeting Page</title> </head> 
  <body> 
     <f:view> 
        <h3> 
           <h:outputText value="Welcome" />, 
        </h3> 
     </f:view> 
 </body> 
</html>

Now, when I access test.faces, I can see my test.jsp file.

When I give any input less than 3 or greater than 15, it shows validation error. So for good.

But when I give valid input, it goes to the login() method of LoginBean class, I can see 'success' and 'failure' depending on the input, on console, but can't see the next page (means, navigation rules defined in faces-config.xml are not working...)

What could be the reason??

Thanks a lot.

I got it working. It was very silly mistake. I was not specifying correct path of JSPs in faces-config.xml.

I didn't say it. I'm just telling you what this tiny ad said.
