Getting user's email in a Workflow Action

[Johannes Goerke <jo...@wsi-gris.uni-tuebingen.de>]

Hello,

I'm just trying to get the email address from a user in a Workflow
Action.
I have the userID (I extended the Workflow - AbstractAction-execute -
method a little bit so that I have the situation available), but for now
I don't see how to get the email address of the user.

For now, I try something like:
public class HelloWorld extends AbstractAction {

 public void execute(Situation situation, WorkflowInstance instance)
throws WorkflowException {
	    System.out.println("HelloWorld: Hello World");
	    System.out.println("HelloWorld: Parameter: " + params);
	    System.out.println("HelloWorld: User: " +
((CMSSituation)situation).getUserId());

		// now get the user's email address
	    try {
		PublicationAccessControllerResolver pacr = new
PublicationAccessControllerResolver();
	    	DefaultAccessController dac =
DefaultAccessController)(pacr.doResolveAccessController("/default/index.
html"));
		AccreditableManager am =
(AccreditableManager)dac.getAccreditableManager();
	        UserManager um = am.getUserManager();
	        User u =
um.getUser(((CMSSituation)situation).getUserId());
	    
    	        System.out.println("HelloWorld: User - email: " +
u.getEmail());
	    } catch (Exception e){
		System.out.println("Hello World: no email! ");
		e.printStackTrace();
 	    }
}
}

Unfortunately, I get an exception from
PublicationAccessControllerResolver, because this class cannot open the
logging (NullPointerException) in the method
doResolveAccessController().

Does anybody kow how to get the user's email?

Thank you in advance!

Johannes

Your approach would basically be correct, but unfortunately it is not
possible to implement this.

The access control components use the Avalon framework, they can only
be obtained by Avalon components. The workflow action is not based
on Avalon, therefore you can't access these components.

You could implement a dirty solution by accessing the user XML files
directly, but of course that will cause trouble when the implementation
changes, or you use LDAP, or other changes occur.
