Hi there, I'm cuurently replacing JSF RI of Sun By Myfaces. The problem I ran into is the following: we had subclassed the sun ViewhandlerImpl class and re-implemented the createview method. Basiccaly this reimplementation checked the viewid to see wether or not it was pointing to a public or private section of the webapp. If it pointed to the private section and the User was not logged in, a view was created for the login page otherwise the requested page view was created. This worked OK for the sun RI.
For Myfaces I did the same (subclassed JspViewHandlerImpl). The problem here
is that although I call the super.createView(...) for the login page, the
original requested page is created.
How can I fix this?. Is there another way to solve this problem neatly?

Here is the subclass code snippet of the overridden method :
public UIViewRoot createView(FacesContext fc, String viewId) {
// The pageUrl is the ViewId, check if it is a public or private
// page....
if (viewId.indexOf("jsp/public/") < 0) { // If the page is
considered
// to be private
HttpSession session = (HttpSession)
fc.getExternalContext()
.getSession(true);
String userId = (String)
session.getAttribute("_login_");
if (null == userId) {// check if user is logged in....
// user is not authenticated yet, see if the
uid and pwd is
// supplied on the request
// >>>>>>>>> check if uid and pwd are send alog
with the request
String uid = (String) fc.getExternalContext()
.getRequestParameterMap().get("uid");
String pwd = (String) fc.getExternalContext()
.getRequestParameterMap().get("pwd");
if (uid != null) {
// try to simulate the login using the
uid and pwd value
LoginManager loginManager = null;
javax.faces.context.FacesContext
context =
javax.faces.context.FacesContext
.getCurrentInstance();
javax.faces.application.Application app
= context
.getApplication();
javax.faces.el.VariableResolver
resolver = app
.getVariableResolver();
Object obj =
resolver.resolveVariable(context,
"loginManager");
if (obj != null) {
loginManager = (LoginManager)
obj;
loginManager.setUserId(uid);
loginManager.setPassword(pwd);
String result =
loginManager.login();
if
(result.equals(LoginManager.AUTHENTICATION_OKE)) {
return
super.createView(fc, viewId); // send the
// original
// requested
// page
}
}
}
// if not logged in (or implicit login failed ,
redirect to the
// loging page
// store the requested page on the session for
redirect after
// succesfull login
session.setAttribute(REQUESTED_PAGE, viewId);
session.setAttribute(REQUESTED_PAGE_QUERY_STRING,
((HttpServletRequest)
fc.getExternalContext()
.getRequest()).getQueryString());
return super.createView(fc, LOGIN_PAGE);//
Redirect to the login
// page
}
}
if (viewId.indexOf("originalRequestedUrl.jsp") >= 0) { // show
the
// previous
// requested
// page (the one
// before
// redirect to
// login
HttpSession session = (HttpSession)
fc.getExternalContext()
.getSession(true);
String originalUrl = (String)
session.getAttribute(REQUESTED_PAGE);
if (originalUrl != null) {
// restore original query string
Object queryString = session
.getAttribute(REQUESTED_PAGE_QUERY_STRING);
if (queryString != null) {
HttpServletRequest request =
((HttpServletRequest) fc
.getExternalContext().getRequest());
request.setAttribute(REQUESTED_PAGE_QUERY_STRING,
queryString);
session.removeAttribute(REQUESTED_PAGE_QUERY_STRING);
}
}
// if no original url, just show the login page again
if (originalUrl == null)
originalUrl = LOGIN_PAGE;
return super.createView(fc, originalUrl);// Redirect to
the login
// page
}
return super.createView(fc, viewId); // send the original
requested
// page
}
