Several Java Servlet Authentication Methods

Is it possible to have multiple authentication methods for a Java servlet? For example, in addition to forms-based authentication, in addition to opening an id-based identifier , so that users can choose how they enter the system.

Yes.

However, I would suggest doing this using servlet filters, and not just on the servlet itself.

Follow the steps in this article and override the method isAuth()so that it authenticates in any mode. In (very rude, unverified) code:

@Override protected boolean isAuth()
{
    String authMode = (String)(getSession(true).getAttribute("authMode"));
    if (authMode == null) { return false; }
    if (authMode.equals("open id") {
        //do open id authentication steps here
        //return true if authentication passes
    }
    else if (authMode.equals("some other authentication") {
        //do some other authentication steps here
        //return true if authentication passes
    }
    ...
    return false;    
}
