Spring Web Flow with JSF navigation

Hi,

I'm writing a sample spring web flow (2.2.1) app with jsf2 as view technology. I guess I've got everything right in terms of configuration. However when I click on the "login" commandbutton of the jsf page, the flow does not go the next view (Welcome). Am I missing something ?

main-flow.xml

<flow xmlns="http://www.springframework.org/schema/webflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/webflow
http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">

<view-state id="Login">
<transition on="login" to="Welcome" />
<transition on="cancel" to="Cancel"/>
</view-state>

<end-state id="Welcome" />
<end-state id="Cancel" />

</flow>

Login.xhtml

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">

<h:head><title>Spring Web flow with JSF</title></h:head>

<h:body>
<h5>Please login to continue</h5>
<h:form>
<h:panelGrid columns="2">
<h:outputText value="Username"/>
<h:inputText value="#{loginBean.username}"/>

<h:commandButton id="loginButton" action="login" value="Login" />
<h:commandButton id="cancelButton" action="cancel" value="Cancel" />
</h:panelGrid>
</h:form>
</h:body>
</html>

Welcome.xhtml

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">

<h:body>
Welcome to Spring Web flow with JSF, <h:outputText value="#{loginBean.username}"/>
</h:body>

</html>

@Component("loginBean")
public class LoginControllerBean implements Serializable {

private String username;
private String password;

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
System.out.println("Setting username to " + this.username);
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
System.out.println("Setting password");
}

}

Where did you define your "login" in <transition on="login" to="Welcome" />
"login" is not defined in the loginbean which is your container for login.xhtml

login is the name of the action attribute of CommandButton in Login.xhtml. I got it working just now. I had to replace end-state with view-state and write a different end-state. With the previous flow, the end state was bringing up the Login state again.

This is the new main-flow.xml:

<view-state id="Login">
<transition on="login" to="Welcome" />
<transition on="cancel" to="Cancel"/>
</view-state>

<view-state id="Welcome">
<transition on="thankYou" to="end"/>
</view-state>

<view-state id="Cancel">
<transition on="noProblem" to="end"/>
</view-state>

<end-state id="end"/>

I am trying to do something similar.
I am not able to show the login page it self
When I had login.xhtml out of webflow, everything worked fine. But I am not bale to start login page with webflow.
Would you mind sharing your config files??

Thanks
Vinaya

Hope you find these useful.

Hi,

I have the same configurations.
I have the loginbean as

Code:

public class LoginBean implements AuthenticationManager, Serializable{ private String username; private String password; 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 LoginBean() { super(); } public void reset(){ this.username = null; this.password = null; } @Override public Authentication authenticate(Authentication authentication) throws AuthenticationException { System.out.println("In auhenticate :" + username + ":" + password); return authentication; }

My login.xhtml is

Code:

<table border="0" width="100%"> <tr> <td align="center" colspan="2"><img src="images/master_ui/logo.gif" /></td> </tr> <tr> <td colspan="2" align="center"> <h:messages style="font-size: 10px; font-weight: bold;color: #E90649" id="messages" layout="table" globalOnly="true" showDetail="true" /> </td> </tr> <tr> <td align="center"> <font color="#0000CC" face="Arial, Helvetica, sans-serif" size="1.5">User Name:</font> </td> <td> <h:inputText id="j_username" value="#{loginBean.username}" size="20" maxlength="80"></h:inputText> </td> </tr> <tr> <td align="center"> <font color="#0000CC" face="Arial, Helvetica, sans-serif" size="1.5">Password: </font> </td> <td> <h:inputSecret id="j_password" value="#{loginBean.password}" size="20" maxlength="80" redisplay="true" tabindex="0"></h:inputSecret> </td> </tr> <tr> <td colspan="2" align="center"> <h:commandButton action="j_spring_security_check" value="Login" tabindex="0"/> <h:commandButton value="Reset" action="reset" tabindex="0"/> </td> </tr> </table>

my login.xml is

Code:

<view-state id="login"> <transition on="authenticate" to="main" /> <transition on="reset" to=""/> </view-state>

The authenticate action is not being called and the flow goes to main even though the authentication failed.

Any ideas??

Thanks
Vinaya

Hi Deepak,

Would you mind posting your LoginController??

Thanks
Vinaya

Good shot deepak,

actually this is a bug spring webflow. in the end-state the view is not getting rendered. But the same would work when you use JSPs. That is obvious that we need to have a view in end-state.

See in your workaround user have u invoke 'thankyou' action then only it reaches to end-state.
