How can I retrieve the email address of a user ?

[goschan]

I though that the email address of a user was stored in the set of Principals of a user, I try to list it :

Identity identity = ConversationState.getCurrent().getIdentity();
Iterator<Principal> u = identity.getSubject().getPrincipals().iterator();

Utils.trace(getClass(), "Principals:");

while (u.hasNext())
{
  Utils.trace(getClass(), u.next().toString());
}

And for the user root :

[2010-04-01 19:54:50,573] TRACE [AuthenticatorBean] Principals:
[2010-04-01 19:54:50,573] TRACE [AuthenticatorBean] Roles
[2010-04-01 19:54:50,573] TRACE [AuthenticatorBean] root

According to Portlet 2.0 Specification PLT.21.2 you should get the user's email (if it's available) by using the following code:

{code}
Map userInfo = (Map) request.getAttribute(PortletRequest.USER_INFO);
String userEmail = (userInfo!=null) ? (String)
      userInfo.get(PortletRequest.P3PUserInfos.USER_HOMEINFO_ONLINE_EMAIL) : null;
if (userEmail == null)
{
   userEmail = (userInfo!=null) ? (String)
         userInfo.get(PortletRequest.P3PUserInfos.USER_BUSINESSINFO_ONLINE_EMAIL) : null;
}
{code}

However, at the moment GateIn doesn't make it available in this way (file a feature request here).

Using GateIn specific API you can get it by:

{code}
PortalContainer container = PortalContainer.getInstance();
OrganizationService orgService = (OrganizationService) container.getComponentInstanceOfType(OrganizationService.class);
UserHandler userHandler = orgService.getUserHandler();
User user = userHandler.findUserByName(request.getUserPrincipal().getName());
String email = user.getEmail(); 
{code}

Where 'request' is RenderRequest.

I didn't test this, but maybe it will work

Thank you, it works

PortalContainer container = PortalContainer.getInstance();
OrganizationService orgService = (OrganizationService) container.getComponentInstanceOfType(OrganizationService.class);
UserHandler userHandler = orgService.getUserHandler();

User user = null;

try {
     user = userHandler.findUserByName(FacesContext.getCurrentInstance().getExternalContext().getUserPrincipal().getName());
} 
catch (Exception e1) {
     // TODO Auto-generated catch block
     e1.printStackTrace();
}

String email = user.getEmail();

Now I want to retrieve all the users of one group. Do youknow how can I do that?

Thank you.

Take a look at UserHandler class. You have many methods there. This one looks promising:

{code}
public ListAccess<User> findUsersByGroupId(String groupId) throws Exception;
{code}

Hi Benjamin!

I tried your code, but I don't know which classes or packages do I need to import. For example I've already imported org.exoplatform.services.organization.OrganizationService class, but the getComponentInstanceOfType method on container variable is not recognised by my environment (NetBeans 6.8). I also tried to look for the UserHandler class, but unfortunately I did not manage to find it.

Could you please, provide me all imports needed for your example (or the whole .java file, which you works for you)?

Thanks a lot

the org.exoplatform.container.PortalContainer is located in the exo.kernel.container project.

you can look for its binaries at : http://repository.jboss.com/maven2/org/exoplatform/kernel/exo.kernel.container/
