Question

Access SPRING_SECURITY_LAST_EXCEPTION from Wicket

Answer 1

A:

While I have never tried it, I think this should be the way:

EDIT: I fixed the bug now

    Request request = RequestCycle.get().getRequest();
    Object lastException = WebUtils.getSessionAttribute(
        ((ServletWebRequest) request).getHttpServletRequest(),
        WebAttributes.AUTHENTICATION_EXCEPTION
    );

See

WebAttributes (Spring, Javadoc)
WebUtils (Spring, JavaDoc)
Constant Field Values: AUTHENTICATION_EXCEPTION (Spring, JavaDoc)
RequestCycle (Wicket, JavaDoc)

Thanks, but this ends up with a java.lang.ClassCastException: org.apache.wicket.protocol.http.servlet.ServletWebRequest cannot be cast to javax.servlet.http.HttpServletRequest.

Ok, I just found a way to get the HttpServletRequest: HttpServletRequest req = ((ServletWebRequest) getRequest()).getHttpServletRequest(); So, now I have no Exceptions, but the getSessionAttribute method returns null, even if I provide the wrong credentials.

OK, I fixed my bug now, but I'm amazed it doesn't work because that's pretty much what the spring guys are doing e.g. here: https://src.springframework.org/svn/spring-webflow/branches/spring-webflow-2.0-maintenance/spring-webflow-samples/booking-faces/src/main/webapp/WEB-INF/login.xhtml
