#2 Email Verification

[Eduardo de Vera]

The verification of the email must take place in order to avoid mock users.

[Eduardo de Vera]

Once a user has submitted a registration form, the system must verify that the supplied email address is valid. This will be done by submitting an email to the user with link which includes a nonce token that once clicked will activate the user account.

[Eduardo de Vera]

Steve, I have temptavely assigned to you this task.

I would like to discuss the implementation details with you if you don't mind. What is your preferred way? gtalk? irc? forum? email?

[Steve Hoeksema]

We can try forum/email for now, if that becomes tedious, we can look into IRC. Cool?

Looking forward to hearing your thoughts.

[Eduardo de Vera]

Use Case:

User submits a registration form (User registration is a different task)
User details are stored on a database table together with a nonce token.
Email is sent to the user with a link containing that token.
User clicks on the link to activate the account.
User gets successfully registered in the application.

We need a mail server. I suggest you take a look at http://james.apache.org but you are free to use whatever email server you wish.

We need the mail server configured on the web application level. I suggest you take a look at the following web sites:
http://blog.valotas.com/2010/05/mail-session-on-tomcat-and-jetty-via.html (jetty configuration)
http://static.springsource.org/spring/docs/2.0.3/reference/mail.html (spring configuration)

Create a spring service that uses the mailSender and mailTemplate explained on the spring example and sends an email to the user upon registration.

If doubts/questions dont hesitate to contact the team.

[Steve Hoeksema]

Thanks for use case.

I am setup, and have site running locally.

James is perfect because I have used it before.

Looks like I will have a couple hours to work on this today and will post questions if they arise.

Thanks!
Steve

[Steve Hoeksema]

Can you help me understand below calls?

1. I Hit "http://localhost:8080/mpango/" in browser

2. index.jsp is called and re-directs to "http://localhost:8080/mpango/helloWorld.jsf"

3. Spring then serves up http://localhost:8080/mpango/helloWorld.xhtml in browser

I am confused by the magic that is happening between steps 2 and 3.

I have been looking in pom.xml and web.xml, but cannot immediately determine what is happeneing here?

Thanks,
Steve

[Eduardo de Vera]

Take a look at the following article explaining "the magic":

http://www.javabeat.net/articles/39-integrating-spring-and-jsf-1.html

[Steve Hoeksema]

Thanks for link, that helped.

If I am understanding correctly...

1. /mpango is defined in pom.xml here: <artifactId>mpango</artifactId>

2. /mpango is then mapped to here in web.xml:

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

3. index.jsp calls/redirects to hellowWorld.jsf and is mapped in web.xml here:

<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>

4. FacesServlet then takes over, looks in webapp directory for a file that matches "helloWorld," and then displays that file in browser

So the lesson here for me is that the details of how FacesServlet serves up that page is not necessary, and treat FacesServlet as a blackbox...?

Thanks,
Steve

Question/Exception - java.lang.ClassCastException: javax.mail.Session cannot be cast to javax.mail.Session

I am getting this exception, can anyone please help?

Here is where I am at so far:

I setup james mail server on my local, added users and tested.

Added register.jsp and register.xhtml to webapp directory

Copied helloWorld.xhtml contents into register.xhtml, copied index.jsp contents into register.jsp and changed response.sendRedirect parameter to register.jsf

Added registerBacking.java to web dir. and copied helloWorldBacking.java contents into registerBacking.java

All is well up to this point, then...

I added:

To jetty-env.xml:

<New id="mailsessionid" class="org.mortbay.jetty.plus.naming.Resource">
<Arg>mail/Session</Arg>
<Arg >
<New class="org.mortbay.naming.factories.MailSessionReference">
<Set name="user">root</Set>
<Set name="password">root</Set>
<Set name="properties">
<New class="java.util.Properties">
<Put name="mail.host">localhost</Put>
<Put name="mail.debug">true</Put>
<Put name="mail.smtp.auth">true</Put>
</New>
</Set>
</New>
</Arg>
</New>

To pom.xml:

<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.1</version>
</dependency>

To context.xml:

<ResourceLink name="mail/Session"
global="mail/Session"
type="javax.mail.Session"/>

To web.xml:

<resource-ref>
<description>Session</description>
<res-ref-name>mail/Session</res-ref-name>
<res-type>javax.mail.Session</res-type>
<res-auth>Container</res-auth>
</resource-ref>

To registerBacking.java:

public String send() throws NamingException {

InitialContext initial = new InitialContext();

System.out.println("******** initial.lookup(java:/comp/env/mail/Session) = "+initial.lookup("java:/comp/env/mail/Session").getClass()+" ***********");

Session session = (Session) initial.lookup("java:comp/env/mail/Session");

return "success";
}

I then run mvn jetty:run and server starts with several points of interest(see console output below)

I then fill out user/email fields in form, click register button, and I get this exception:

java.lang.ClassCastException: javax.mail.Session cannot be cast to javax.mail.Session

In console output you can see from the System.out I added, that lookup is returning a javax.mail.Session class, so I am confused by this exception.

Complete console output:

[Eduardo de Vera]

Hi Steve,

I think it is my fault that I miss guided you pointing you to a Jetty Mail JNDI resource on one of the links I posted here. According to what I read on the Spring documentation you can work your way around it and not use JNDI but connect directly to the SMTP server from Spring making it easier for you to implement your solution.

I think you can by pass your problem if you follow the instructions found on the next link:
http://static.springsource.org/spring/docs/3.0.x/reference/mail.html

Take a look at it and see if it helps!

Besides this problem, I don't understand why you have created register.jsp and register.xhtml as I believe you should be able to reuse the same screens that Jay has delivered as we should send an email to users that register using the userRegistration.xhtml.

[Steve Hoeksema]

Hi,

I will implement using link you provided, thanks.

Regarding your question about files I created...I had old code base, did svn update, and I now see Jay changes.

I will use userRegistration.xhtml moving forward.

Thanks for quick response!

Steve

[Eduardo de Vera]

Steve,

Please document the installation of the James server (or post a URL on which it's documented) so that we can follow a step by step instructions in order to execute the feature you are developing.

Thanks!

[devdlee]

Please provide resources that will help me implement this with JMS.
I am also searching on my own.
