How do I get the user information for a page?

Question

I would like to display information about the person that created a page in CQ.  I know I can get the createdBy information from the page properties, but how can I turn that into a user object where I can get more detialed information about that user?

If you are within an OSGi bundle you can use the SlingRepository Service. Now it depends how you develop your OSGi services and components. I use the maven scr plugin for this. With this plugin it is possible to get references to services with java annotaions.
Example:
@Component(name="SampleService",
        label = "SampleService",
        description = "SampleService",
        immediate = true, enabled = true, metatype = true)
@Services({ @Service(value = SampleService.class) })
@Properties({
@Property(name = "service.description", value = "SampleService"),
@Property(name = "service.vendor", value = ") })
public class SampleServiceImpl implements SampleService
@Reference(policy = ReferencePolicy.STATIC)
private SlingRepository repository;
    public void openAdminSession() {
        Session session = null;
        if (repository != null) {
            try {
                session = repository.loginAdministrative(null);
                //do something here
            } catch (RepositoryException e) {
                LOG.error("Unable to open admin session:" + e.toString());
            } finally{
                                          if(session != null){
                      session.logout();
To access a service from a JSP page you can use the reference of the SlingScriptHelper. You have to use the <cq:defineObjects/> tag.
Example jsp:
<cq:defineObjects/>
SlingRepository repository = sling.getService(SlingRepository.class);
Session session = null;
        if (repository != null) {
            try {
                session = repository.loginAdministrative(null);
                //do something here
            } catch (RepositoryException e) {
                LOG.error("Unable to open admin session:" + e.toString());
            } finally{
                                          if(session != null){
                      session.logout();
