here is my example :
1.view
| <h:form id="login">
| <rich:panel style="width: 400px;">
| <f:facet name="header">Login</f:facet>
| <p class="LogintCaption">Please login using any
username and password</p>
| <div class="dialog">
| <h:panelGrid columns="2" rowClasses="prop"
columnClasses="name,value" style="text-align:left">
| <h:outputLabel
for="username">Username</h:outputLabel>
| <h:inputText id="username"
| value="#{identity.username}"
styleClass="LoginInput"/>
| <h:outputLabel
for="password">Password</h:outputLabel>
| <h:inputSecret id="password"
| value="#{identity.password}"
styleClass="LoginInput"/>
| <h:outputLabel
for="language">Language</h:outputLabel>
| <h:selectOneMenu id="language"
styleClass="LoginLangCombo" value="#{localeSelector.language}"
| onchange="submit();"
|
valueChangeListener="#{localeSelector.select}">
| <f:selectItems
value="#{localeSelector.supportedLocales}"/>
| </h:selectOneMenu>
| <h:outputLabel for="rememberMe">Remember
me</h:outputLabel>
| <h:selectBooleanCheckbox id="rememberMe"
|
value="#{identity.rememberMe}"/>
| <h:outputLabel
for="LogInButn"></h:outputLabel>
| <h:commandButton id="LogInButn"
value="Login" action="#{identity.login}"/>
| </h:panelGrid>
| </div>
| <h:messages id="modalError" layout="table"
style="padding:0px;"/>
| </rich:panel>
| </h:form>
|
1. Backing bean :
| @Name("authenticator")
| public class Authenticator {
| // logger instance
| @Logger
| Log log;
| // Seam Identity Session Bean For User Identification
| @In
| Identity identity;
| // UserName Fro Session Context.
| private static final String USER_VAR = "currentUser";
| // Session Context
| @In
| Context sessionContext;
| // Database Entity Manager
| @In(value = "#{entityManager}")
| EntityManager em;
| // Faces Messages
| @In
| private FacesMessages facesMessages;
|
| public boolean authenticate() {
| try {
| facesMessages.clear();
| log.info("authenticating = " + identity.getUsername());
| List<Users> users = (List<Users>)
em.createNamedQuery("Users.findByUserName").setParameter("userName",
identity.getUsername()).getResultList();
| if (users == null || (users != null && users.isEmpty())) {
| facesMessages.addToControl("username", "User
#{user.username} does not exists");
| //FacesMessages.instance().add("User #{user.username} does not
exists");
| return false;
| } else {
| for (Users user : users) {
| byte dbpaswd[] = user.getUserPwd();
| String strpwd = identity.getPassword();
| MessageDigest md5 = MessageDigest.getInstance("MD5");
| md5.reset();
| md5.update(strpwd.getBytes());
| byte[] userpasswd = md5.digest();
|
| boolean result = MessageDigest.isEqual(userpasswd, dbpaswd);
| if (result) {
| identity.addRole("admin");
| sessionContext.set(USER_VAR, user);
| return true;
| }
| }
| }
| facesMessages.addToControl("password", "Incorrect Password
For This User");
| //FacesMessages.instance().add("Incorrect Password For This
User");
| return false;
| } catch (Exception e) {
| e.printStackTrace();
| facesMessages.add("Could not login. System Error");
| //FacesMessages.instance().add("Could not login. System
Error");
| return false;
| }
| }
| }
|
|

| Incorrect Password For This User
| Incorrect Password For This User
