If we need to provide our own JSF login page then we can use following JSF code and corresponding managed bean code :
JSF Code:
<af:panelFormLayout id="pfl1">
<af:message for="loginname" partialTriggers="cb1" />
<af:inputText label="Login Name" id="loginname" />
<af:inputText label="Password" id="password" />
</af:panelFormLayout>
<af:panelGroupLayout id="pgl2">
<af:commandButton text="Submit" id="cb1" actionListener="#{MyApp_ManagedBean.Login}"/>
<af:commandImageLink text="SignUp" id="cil1"/>
</af:panelGroupLayout>
Managed Bean Code:
public void Login(ActionEvent actionEvent) {
FacesContext fctx=FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest)fctx.getExternalContext().getRequest();
HttpServletResponse response = (HttpServletResponse)fctx.getExternalContext().getResponse();
UIViewRoot viewRoot=fctx.getViewRoot();
RichInputText userName = (RichInputText)viewRoot.findComponent("pt1:loginname");
//pt1 indicated the page template naming container.
String userNameStr = (String)userName.getValue();
RichInputText password = (RichInputText)viewRoot.findComponent("pt1:password");
String passwordStr = (String)password.getValue();
try
{
int authSuccess=ServletAuthentication.login(userNameStr,passwordStr,request,response);
if(authSuccess==ServletAuthentication.AUTHENTICATED)
{
try{
ExternalContext ectx=fctx.getExternalContext();
//Using Controller Context is recommended to implement redirect logic instead of directly calling //External Context redirect method and passingredirect URL in it "faces/RedirectPage".
ControllerContext controllerCtx = null;
controllerCtx = ControllerContext.getInstance();
String activityURL = controllerCtx.getGlobalViewActivityURL("WelcomePage");
ectx.redirect(activityURL);
}catch(IOException ioex){ioex.printStackTrace();}
}
}
catch(LoginException loginex)
{
String message="Authentication Failed. Please try again";
fctx.addMessage("pt1:loginname", new FacesMessage(FacesMessage.SEVERITY_ERROR,message,null));
}
}
}
