15.12. Extending the Identity component

If your application has special security requirements, you may need to extend your Identity component. The following example shows an Identity component extended with an additional companyCode field to handle credentials. (Usually this would be handled by a Credentials component.) The install precedence of APPLICATION ensures that this extended Identity is installed instead of the built-in Identity. 
@Name("org.jboss.seam.security.identity")
@Scope(SESSION)
@Install(precedence = APPLICATION)
@BypassInterceptors
@Startup
public class CustomIdentity extends Identity {
  private static final LogProvider log = 
                       Logging.getLogProvider(CustomIdentity.class);

  private String companyCode;

  public String getCompanyCode() {
    return companyCode;
  }

  public void setCompanyCode(String companyCode) {
    this.companyCode = companyCode;
  }

  @Override
  public String login() {
    log.info("###### CUSTOM LOGIN CALLED ######");
    return super.login();
  }
}

Warning

An Identity component must be marked @Startup so that it is available immediately after the SESSION context begins. Failing to do this may render certain Seam functionality inoperable in your application.
