request.getUserPrincipal() != null seems to be valid only the first time a
request is made. The following requests (made by the requestFactory),
getUserPrincipal() returns null. Here´s my code in my AuthFilter class:
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse, FilterChain filterChain) throws IOException,
ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse) servletResponse;
if(request.getUserPrincipal() == null) {
response.setHeader("WWW-Authenticate", "FORM realm=\"userRealm\"");
response.sendError(HttpServletResponse.SC_UNAUTHORIZED);
return;
}
What am I doing wrong?
