SimpleCallbackHandler no longer in weblogic.jar for WebLogic 10.3g

Question

I was using the weblogic.security.SimpleCallbackHandler in WebLogic 9.2 to authenticate users. I looked at the documentation for 10.3g and it still mentions this class is available, however it is not in the weblogic.jar file nor in the javadocs. Here is the URL where I was looking. http://e-docs.bea.com/wls/docs103/security/thin_client.html#wp1035574.
The only CallbackHandler in the 10.3g release seems to be the weblogic.security.URLCallbackHandler class. I tried replacing the SimpleCallbackHandler with this class. When I put the weblogic.jar in my classpath and build, I get the following error.
class file for weblogic.security.acl.internal.AuthenticatedSubject not found
ServletAuthentication.runAs(mySubject, request);
Indeed, this class is not in the weblogic.jar file. Both SimpleCallbackHandler and AuthenticatedSubject were in the weblogic.jar for WebLogic 9.2
<code>
import javax.security.auth.Subject;
import weblogic.security.SimpleCallbackHandler;
import weblogic.security.services.Authentication;
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
LoginForm loginForm = (LoginForm) form;
Subject subject = Authentication.login(new SimpleCallbackHandler(loginForm.getUsername(), loginForm.getPassword().getBytes()));
weblogic.servlet.security.ServletAuthentication.runAs(subject, request);
<./code>
Why were these removed and not deprecated???

Answer 1

SimpleCallbackHandler does not exist in weblogic.jar. Used the following code to get around this. WebLogic documentation offers this as an alternative to using SimpleCallbackHandler.
Subject subject = Authentication.login(new URLCallbackHandler(uid, pwd));
weblogic.servlet.security.ServletAuthentication.runAs(subject, request);
This code agrees with the snippet provided in WebLogic documentation
