If we are not allowed to use static variables in the beans session, how do we determine the registrar?

Question

I read from time to time that we should not use static variables in a bean session. Then, how should I get the logger for this bean and use it in all bean methods?

( ) - . IMO Logger, / :

public class SomeTypeOfBean {
    private static final Logger log = Logger.getLogger(SomeTypeOfBean.class);
    //...
}
