I am building a small hello world JSF application.
My index.xhtml is as follows
<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<body>
Hello user.
<h:form>
<h:inputText value="#{test.value}"></h:inputText>
<h:commandButton value="Enter" action="welcome"></h:commandButton>
</h:form>
</body>
</html>
My welcome.xhtml is as follows
<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<body>
<h2>Welcome #{test.value}</h2>
</body>
</html>
My managed bean is as follows
package com.test.testclass;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean

public class Test {
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
My web.xml is as follows
<?xml version="1.0" encoding="UTF-8"?>

I am getting the following error when I enter a string in the index page and hit enter
HTTP Status 500 - Internal Server Error
type Exception report
