Question

How can i make the success message display out? I have the following code, but only the warning message appear. What do i have to change so that the success message will be display out in my success page ?
userbean.java :
public String Login() throws Exception {
String status = "failure";
current=userBo.validateUser(getLogin(),getPass());
if(current!=null){ exist=false; status = "success";
String message = "submitted successfully !!";
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(message)); }
exist=true; return status; }
login.xhtml :
<f:view>
<h:form>
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<th>Username</th>
<td><h:inputText value="#{user.login}"
styleClass="login-inp" /></td>
</tr>
<tr>
<th>Password</th>
<td><h:inputSecret value="#{user.pass}"
onfocus="this.value=''" styleClass="login-inp" /></td>
</tr>
<tr>
<th></th>
<!-- <td><input type="button" class="submit-login" /> -->
<td><h:commandButton action="#{user.checkUser}" styleClass="submit-login" />
<h:messages globalOnly="true" />
</td>
</tr>
</table>
</h:form>
</f:view>
success.xhtml :
<h:form>
<h:body>
<h1>heyyyy ,y sucseded !!!</h1> <br/><br/>
<h:commandLink action ="#{user.logout}" > disconnect </h:commandLink>
</h:body>
</h:form>
warning message :
Infos: WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=null[severity=(INFO 0), summary=(submitted successfully !!), detail=(submitted successfully !!)]

Answer 1

Your <h:messages globalOnly="true" /> is been placed in the wrong view. You placed it in login.xhtml, but you're navigating to success.xhtml on success instead of returning to login.xhtml. If you put the <h:messages globalOnly="true" /> in success.xhtml, then it will be displayed the way you expected.

Answer 2

on your action method i.e. action="#{user.checkUser}" return a string that string will decide which page to show using your faces-config.xml file.
eg.
< navigation-rule>
< from-view-id>*< /from-view-id>
< navigation-case>
<from-outcome>ReturnedString</from-outcome>
<to-view-id>success.xhtml(path of your file)</to-view-id>
<redirect/>
</navigation-case>
< /navigation-rule>
this will definately work.
