JSF 2.1
Tomcat 7.0
Is this a wrong use of dependency injection?
It works ok moving around the page. But "it works" is not the same as "it's correct".
I would use this pattern also for search purpose. I have a request and i like to use it to populate a table in the same page. Is this possible?

UserBean.java
#ManagedBean (name="user")
#SessionScoped
public class UserBean implements Serializable {
private String Username;
private String Password;
private String Roles;
/** Creates a new instance of UserBean */
public UserBean() {
}
/**
* #return the Username
*/
public String getUsername() {
return Username;
}
/**
* #param Username the Username to set
*/
public void setUsername( String Username ) {
this.Username = Username;
}
/**
* #return the Password
*/
public String getPassword() {
return Password;
}
/**
* #return the Roles
*/
public String getRoles() {
return Roles;
}
/**
* #param Roles the Roles to set
*/
public void setRoles( String Roles ) {
this.Roles = Roles;
}
/**
* #param Password the Password to set
*/
public void setPassword( String Password ) {
this.Password = Password;
}
change password also use the userBean and has his changePasswordBean.
JSF 2 allows you injecting managed beans in other managed beans. This is only limited by the scope of the bean you're actually injecting, which has to be greater than the scope of the bean you actually are in. I mean, you can inject #SessionScoped bean in a #ViewScoped one, but not in the other way. As you follow that convention, I think you're doing it well.
Generally, your application should be composed by #ViewScoped or #RequestScoped beans to handle current user input/outputs and wider scoped beans for session or application means. So, when user logs in, it's a good idea to maintain his data in a session context, however I suggest you not to maintain user's password into session, at least if you're not going to use it once the login has been succesfully done.
Finally the question you make about search requests, I think you can implement a search input in your page and make your result table load dinamically depending on the search. Just use ajax to obtain it without having to reload the whole page. You can implement everything in a #ViewScoped bean, but remember not to return navigation results in your listener methods if you want to maintain the bean working.

I'm new to jsf technology and I'm trying to understand when and how the ViewScoped jsf bean is initialized.
I have a sample app with 2 beans
ApplicationScopedBean.java
#ManagedBean
#ApplicationScoped
public class ApplicationScopedBean implements Serializable {
private int incrementedCounter =0;
public int getIncrementedCounter() {
incrementedCounter += 1;
return incrementedCounter;
}
}
ViewScopedBean.java
#ManagedBean
#ViewScoped
public class ViewScopedBean implements Serializable {
#ManagedProperty(value = "#{applicationScopedBean}")
private ApplicationScopedBean applicationScopedBean;
private int reincarnationNumber;
private int accessCounter;
#PostConstruct
public void initialize() {
accessCounter = 0;
reincarnationNumber = applicationScopedBean.getIncrementedCounter();
System.out.println("Initializing viewScoped stateManager with reincarnationNumber value = " + String.valueOf(reincarnationNumber));
}
public void noAction() {
//do nothing
}
public int getReincarnationNumber() {
return reincarnationNumber;
}
public int getAccessCounter() {
accessCounter += 1;
return accessCounter;
}
public ApplicationScopedBean getApplicationScopedBean() {
return applicationScopedBean;
}
public void setApplicationScopedBean(ApplicationScopedBean applicationScopedBean) {
this.applicationScopedBean = applicationScopedBean;
}
}
ApplicationScoped bean is created only once for the application launch.
Every time ViewScoped bean is being created, the reincarnationNumber is being increased by 1.
I also have a simple jsf page to display these values:
index.xhtml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>View Scoped bean test</title>
</h:head>
<h:body>
<h:form>
<p>ViewScoped bean reincarnation is <h:outputText value="#{viewScopedBean.reincarnationNumber}"/></p>
<p>ViewScoped bean access counter is <h:outputText value="#{viewScopedBean.accessCounter}"/></p>
<h:commandButton type="submit" value="no action" action="#{viewScopedBean.noAction()}"/>
<h:commandButton type="submit" value="reload this page" action="index"/>
</h:form>
</h:body>
</html>
The problem:
When I launch the application the first time, I already have reincarnationNumber value equal to 3.
In other words, I have this info displayed in browser:
ViewScoped bean reincarnation is 3
ViewScoped bean access counter is 1
Why is that?
Why ViewScoped bean has bean created 3 times?
Thanks in advance!
SOLUTION
As it is stated in the comments, the cause was "start browser" checkbox checked in Run Configurations in my IntelliJ IDEA. The trick is when browser is auto-started from IDE I have viewScopedBean initialized 3 times.
It's not created 3 times, just called the getter several times... and that's because... you can check this answer:
Why JSF calls getters multiple times
i have a datatable with one row , i need to edit the fields of this row so i have a few inputText with the values, but when i edit them and click on the commandbutton(that calls the method "actualizarUsuario" the values are passed as null.
this is my bean code:
#ManagedBean(name = "user")

this.u=controlador.getUser(iduser);
}
public Usuario getU() {
return u;
}
public void setU(Usuario u) {
this.u = u;
}
public long getSelection() {
System.out.println("selection value----------->"+selection);
return selection;

}
public void setSelectionrol(long selectionrol) {

}
public String getNombres() {

}
public void setNombres(String nombres) {

public void setCheck(Boolean check) {
this.check = check;

ExternalContext externalContext = facesContext.getExternalContext();
Map<String, String> parameterMap = (Map<String, String>) externalContext.getRequestParameterMap();

apellidoM=parameterMap.get("apellidoM");
check=Boolean.parseBoolean(parameterMap.get("check"));
//test
System.out.println(nombres+" "+apellidoP+" "+apellidoM+" "+check);
u.setNombres(nombres);
u.setApellidoPaterno(apellidoP);
u.setApellidoMaterno(apellidoM);
u.setActive(check);
controlador.saveUsuario(u);
}
}

Your concrete problem is caused because you used the wrong parameter names. Look in the generated HTML output and the HTTP traffic monitor for the right parameter names.
However, your actual problem is bigger: your view/model approach is completely wrong. You shouldn't be using a <h:dataTable> at all. It is intented for a collection of entities like List<User>, not for a single entity like User. You should be using <h:panelGrid>. You don't need to explode/flatten model properties in controller at all. You have those properties already in the model itself. You don't need to manually traverse the request parameter map. JSF will already do all the job for you.
I won't rewrite this mess for you, but to the point you should follow the following kickoff example:
Model:
public class User {
private Long id;
private String username;
private String firstname;
private String lastname;
// ...
// Autogenerate standard getters/setters.
}
Controller:
#ManagedBean
#ViewScoped
public class EditUser {
private User user; // Initialize it in postconstruct or as viewparam.
private UserService service; // Initialize it as #EJB or in postconstruct.
public void save() {
service.save(user); // That's all. Really.
}
public User getUser() {
return user;
}
// No other getters/setters! They are all already in User class.
}
View:
<h:panelGrid>
<h:inputText value="#{editUser.user.username}" />
<h:inputText value="#{editUser.user.firstname}" />
<h:inputText value="#{editUser.user.lastname}" />
<h:commandButton value="save" action="#{editUser.save}" />
</h:panelGrid>
That's all. See also among others this JSF 2.0 tutorial. As to your attempt to get the user by ID, you should rather use <f:viewParam>, see also What can <f:metadata>, <f:viewParam> and <f:viewAction> be used for? and communication in JSF 2.0.
I put this problem in a simple example, a composite component that calculates the sum of 2 inputs and prints the result in an outputText
Main JSF page:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ez="http://java.sun.com/jsf/composite/ezcomp/">

<h:body>
<ez:Calculator />
<br/>
<br/>

<br/>
<br/>
<ez:Calculator />
</h:body>
</html>
Composite component XHTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>This content will not be displayed</title>
</h:head>
<h:body>
<composite:interface componentType="calculator">
</composite:interface>
<composite:implementation>
<h:form>
<h:inputText id="first" value="#{cc.firstNumber}" />
<h:commandButton value="+" action="#{cc.sum}"/>
<h:inputText id="second" value="#{cc.secondNumber}" />
</h:form>
<h:outputText id="result" value="#{cc.result}" />
</composite:implementation>
</h:body>
</html>
Composite component backing bean:
package ez;
import javax.faces.component.FacesComponent;
import javax.faces.component.UINamingContainer;
#FacesComponent("calculator")
public class Calculator extends UINamingContainer {
private Long firstNumber;
private Long secondNumber;
private Long result;
public Calculator() {
}
#Override
public String getFamily() {
return "javax.faces.NamingContainer";
}
public void setFirstNumber(String firstNumber) {
this.firstNumber = Long.parseLong(firstNumber);
}
public String getFirstNumber() {
if(firstNumber == null) {
return null;
}
return firstNumber.toString();
}
public void setSecondNumber(String secondNumber) {
this.secondNumber = Long.parseLong(secondNumber);
}
public String getSecondNumber() {
if(secondNumber == null) {
return null;
}
return secondNumber.toString();
}
public String getResult() {
if(result == null) {
return null;
}
return result.toString();
}
public void setResult(String result) {
this.result = Long.parseLong(result);
}
public void sum() {
this.result = this.firstNumber + this.secondNumber;
}
}
So, I have 3 Composite Components that all should do the same thing, but when I press a SUM button, after the server processes the request, the result is printed out on the page, but the other 2 components are cleared of their values.
How can I prevent this? How can I force it to retain those values?
UIComponent instances are recreated on every request, hereby losing all instance variables everytime. They basically act like request scoped managed beans, while you intend to have them in the view scope. You need to take view state saving into account on a per-attribute basis. This is normally by default already done for all attributes of #{cc.attrs}. So, if you can, just make use of it:
<cc:interface componentType="calculator">
<cc:attribute name="firstNumber" type="java.lang.Long" />
<cc:attribute name="secondNumber" type="java.lang.Long" />
</cc:interface>
<cc:implementation>
<h:form>
<h:inputText id="first" value="#{cc.attrs.firstNumber}" />
<h:commandButton value="+" action="#{cc.sum}"/>
<h:inputText id="second" value="#{cc.attrs.secondNumber}" />
</h:form>
<h:outputText id="result" value="#{cc.attrs.result}" />
</cc:implementation>
with just this (nullchecks omitted; I recommend to make use of required="true" on the inputs)
#FacesComponent("calculator")
public class Calculator extends UINamingContainer {
public void sum() {
Long firstNumber = (Long) getAttributes().get("firstNumber");
Long secondNumber = (Long) getAttributes().get("secondNumber");
getAttributes().put("result", firstNumber + secondNumber);
}
}
Otherwise, you'd have to take state saving into account yourself by delegating all attribute getters/setters to UIComponent#getStateHelper(). Based on the very same Facelets code as you have, the entire backing component would look like this:
#FacesComponent("calculator")
public class Calculator extends UINamingContainer {
public void sum() {
setResult(getFirstNumber() + getSecondNumber());
}
public void setFirstNumber(Long firstNumber) {
getStateHelper().put("firstNumber", firstNumber);
}
public Long getFirstNumber() {
return (Long) getStateHelper().eval("firstNumber");
}
public void setSecondNumber(Long secondNumber) {
getStateHelper().put("secondNumber", secondNumber);
}
public Long getSecondNumber() {
return (Long) getStateHelper().eval("secondNumber");
}
public void setResult(Long result) {
getStateHelper().put("result", result);
}
public Long getResult() {
return (Long) getStateHelper().eval("result");
}
}
See, no local variables anymore. Note that I also removed the need for those ugly manual String-Long conversions by just declaring the right getter return type and setter argument type. JSF/EL will do the conversion automagically based on default converters or custom Converters. As there's already a default one for Long, you don't need to provide a custom Converter.
Unrelated to the concrete problem, you can safely remove the getFamily() method. The UINamingContainer already provides exactly this. If you were implementing NamingContainer interface instead, then you'd indeed need to provide it yourself, but this is thus not the case here. The above backing component examples have it already removed.
I like to know whats the correct way to create a login/logout mechanizm in jsf2 environment.
I have created a login xhtml form and a Admin bean that stores a static boolean (is_authenticated) . I want to check that variable in every xhtml page , if true? continue , else redirect to login page.
this is Admin.java bean:
#ManagedBean
#SessionScoped
public class Admin implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
static Boolean authenticated;
String username;
String password;
#PostConstruct
public void initialisation() { // init bean on new instance
Admin.authenticated = false;
}
public Boolean getAuthenticated(){
return Admin.authenticated;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String doLogout() {
Admin.authenticated=false;
return "login?faces-redirect=true";
}
public String validity() {
if(username.equals("admin") && password.equals("admin")) {
Admin.authenticated=true;
return "success";
} else {
Admin.authenticated=false;
return "failure";
}
}
}
and this is the main.xhtml:

</ui:composition>
Two questions:
in the jstl 'if' ,I get : "Property 'authenticated' not found on
type com.pkg.name.Admin"
How can I update Admin.authenticate to false from the xhtml file(sorry for the lame question, i'm really new to jsf and web dev in general)
is it good practice to use this static variable? (like an instance of the session variable)
According to me the correct and cleaner way to implement login/logout is to create a filter and apply it to the urls that should be protected(e.g. /admin/*).
If the user sucessfully logs in load his details in session bean. When the user requests a protected page the filter runs first. In the filter get the session from request and call its getAttribute method to get the session bean(jsf stores the session scoped beans as session attributes). If you get the bean object then he is logged in else if you get null he is not authorized and you can redirect him to login page.
For logout you can just call invalidate on the session and all the session scoped attributes will be destroyed.
A working example will be like following:
The SessionScoped bean which will save login information:
UserBean.java
#ManagedBean
#SessionScoped
class UserBean implements Serializable{
private User user;
//getter/setter for user
}
LoginBean.java
#ManagedBean
class LoginBean
{
#ManagedProperty(value="#{userBean}")
private UserBean userBean;
public UserBean getUserBean(){
return userBean;
}
public void setUserBean(UserBean userBean){
this.userBean=userBean;
}
private String username,password;
//getter and setter for username,password
public String checkLogin(){
//check database for user
if(user!=null){
userBean.setUser(user);
}
//...
}
}
LoginFilter.java- We apply this filter to url pattern: /admin/*
#WebFilter("/admin/*")
class LoginFilter implements Filter{
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException {
HttpSession session=((HttpServletRequest)request).getSession();
userBean userBean=(userBean)session.getAttribute("userBean");
if(userBean!=null){
User user=userBean.getUser();
if(user==null){
((HttpServletResponse)response).sendRedirect("login.jsf");
}
else
chain.doFilter(request, response);
}
else
((HttpServletResponse)response).sendRedirect("login.jsf");
}
public void init(FilterConfig fc){}
public void destroy(){}
}
login.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

</h:head>

<h:form>
Username : <h:inputText value="#{loginBean.username}"/>
Password : <h:inputSecret value="#{loginBean.password}"/>
<h:commandButton value="Login" action="#{loginBean.checkLogin}" />
</h:form>
</h:body>
</html>
For log out you can simply call session.invalidate() which will destroy the session along with any session scoped attributes.
This way you don't have to write conditional jstl tags to determine whether the use is logged in or not.
Hope this helps.
i am busy writing a very simple login page using JavaEE6, JSF 2.0 and CDI.
My login page looks as follows (some stuff is removed for clarity):
<html>
<head>
<title>HomeBase - Login</title>
</head>
<body>
<h3>Login</h3>
<h:form>
<div>
<label>UserID:</label>
<h:inputText value="#{loginBean.userid}" />
</div>
<div>
<label>Password:</label>
<h:inputSecret value="#{loginBean.password}" />
</div>
<h:commandButton value="Login" action="#{loginBean.login}" />
</h:form>
</body>
</html>
and the backingbean looks as follows:
#ManagedBean
#RequestScoped
public class LoginBean implements Serializable {
#Inject Logger LOG;
private String userid;
private String password;
public String login() {
LOG.info("Start login procedure.");
if ("gast".equalsIgnoreCase(userid) && "gast".equals(password)) {
SessionBean sessionBean = (SessionBean) FacesContext.getCurrentInstance()
.getExternalContext().getSessionMap().get("sessionBean");
User user = new User();
user.setUserid(userid);
user.setPassword(password);
user.setUsername("Gast");
sessionBean.setUser(user);
return "loginSuccess";
}
return "loginFailure";
}
public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Now when i call the loginpage it gets correctly displayed. Both inputfields are empty. When in debugmode, i can see the getters for both fieldvalues are getting called. Next, i fill in the fields and press the submit button and an immediate nullpointer exception occurs. Clearly the LoginBean is instatiated the first time (when the page is displayed), but NOT when i press the commandbutton.
What happend?
The CDI #Inject doesn't work in a JSF #ManagedBean. Hence LOG remains null.
Use CDI #Named instead of JSF #ManagedBean and make sure that you import #RequestScoped annotation from CDI javax.enterprise.context package instead of JSF javax.faces.bean.
