public class samaction
     sambean bea =  new sambean();
     public String getSuc(){
          System.out.println("hi");
          return "success";
}2 error are
cannot resolve symbol sambean and the bean declaration is
sambean.java
package com.mycompany.messages.bean;
import java.util.*;
import javax.servlet.ServletContext;
import javax.faces.context.FacesContext;
public class sambean{
     private String sam;
     public javax.faces.model.SelectItem[] getSam(){
          javax.faces.model.SelectItem[] sam = {
               new javax.faces.model.SelectItem(new Integer(1),"Peas"),
               new javax.faces.model.SelectItem(new Integer(2),"Cheese")
               return sam;
     public void setSam(String sam){
          this.sam=sam;
