import javax.faces.bean.RequestScoped;
import javax.faces.webapp.FacetTag;
@ManagedBean(name = "facet")
public class facetBean extends FacetTag {
private String table, Fname, Lname, fullName;
private Integer age;
private boolean flag = false;
public String getTable() {
return table;
public void setTable(String table) {
this.table = table;
public String getFname() {
return Fname;
public void setFname(String Fname) {
this.Fname = Fname;
public String getLname() {
return Lname;
public void setLname(String Lname) {
this.Lname = Lname;
public Integer getAge() {
return age;
public void setAge(Integer age) {
this.age = age;
public boolean isFlag() {
return flag;
public void setFlag(boolean flag) {
this.flag = flag;
public String getFullName() {
return fullName;
public void setFullName(String fullName) {
this.fullName = fullName;
/* -- submit method -- */
public String submit() {
flag = true;
fullName = Fname + " " + Lname;
age = age + 1;
return "submit";
 /* -- reset method -- */
public String reset() {
flag = false;
age = null;
Fname = null;
Lname = null;
return "reset";
