10:13 a.m.
I need to send an email to a user when they register on my website that includes a link
back to the website to confirm their email address. I want to dynamically build the URL
depending on the server it is deployed to.
I am trying to use a variable defined in components.xml:
<factory name="basePath"
value="#{facesContext.externalContext.request.scheme}://#{facesContext.externalContext.request.serverName}:#{facesContext.externalContext.request.serverPort}#{facesContext.externalContext.request.contextPath}/"/>
|
NOTE: This text is all one line in components.xml. The forum is wrapping the text here
for display purposes.
I have a SLSB that is invoking Renderer to send an email to the user:
| public String register()
| {
| List existing = em.createQuery("select u.username from User u where
u.username=#{user.username}")
| .getResultList();
|
| if ( existing.size()==0 )
| {
| // save the user
| user.setValidated(false);
| em.persist(user);
| log.info("Registered new user #{user.username}");
| FacesMessages.instance().add("An account has been created for
#{user.username}.");
|
| // setup a verification token
| Token verificationToken = new Token(user.getUsername());
| em.persist(verificationToken);
|
| // place the token hash into the session for use by email verification
| Contexts.getSessionContext().set("outtoken",
verificationToken.getHash());
| log.info("Created a new Token for #{user.username}: #0",
verificationToken.getHash());
|
| // send an email verification
| try
| {
| renderer.render("/emailverification.xhtml");
| FacesMessages.instance().add("An email has been sent to
#{user.email}. Please follow the instructions sent to you via email to complete the
registration process.");
| }
| catch (Exception e)
| {
| log.error("Error sending mail", e);
| FacesMessages.instance().add("There was a problem sending your
verification email. Please try again later.");
| }
|
| return "success";
| }
| else
| {
| FacesMessages.instance().add("User #{user.username} already
exists");
| return null;
| }
| }
|

Here is a sample of the email that is generated:
| Dear Bob,
|
| Thank you for registering for a new account. In order to use your account,
| you must complete your registration by clicking on the link below.
|
| /validate.seam?tk=gnqerr
|
| Regards,

The raw email message shows that the href is not set correctly:
| From: Support <no-reply(a)example.com>
| To: Bob <me(a)glennmarcus.com>

| Content-Type:
multipart/mixed; boundary="----=_Part_28_7998763.1178031447360"

The other variables #{user.name}, #{user.email}, #{outtoken} ) all get resolved correctly.
The #{basepath} does not.
1) Why doesn't #{basepath} resolve?
2) Is there a better way to dynamically build an href in an email message being sent by
Renderer?
Thanks,
Glenn
