    <p:fieldset legend="name of home">

        <!-- form to insert a user data -->
        <h:form>

            <b>name of User:</b>
            <h:inputText value="#{home.name}"/><br/>

            <p:commandButton action="#{home.res}" ajax="false"      
                value="Save" />                                         <!-- button to save -->

import javax.annotation.ManagedBean;
import javax.faces.bean.SessionScoped;

@SessionScoped
@ManagedBean

public class Home {

    //fields
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    //change a page
    public String res(){
        return ("results");
    }
}

  • Looks like your bean is not instatiated correctly. Try to add a constructor with no Parameter. – Jens Mar 16 '15 at 12:02
  • create a costructor -> public home(){} ... but error persist T.T... not change errors T.T – Bonni Mar 16 '15 at 12:10

Change the import of that bean to:

javax.faces.bean.ManagedBean;
