Hi, I'm using Tomcat 4.0.x. I have a requirement to have a login box on the first page of my site. This cannot be done in this version of Tomcat as we get "Invalid Reference to Login Page", as the requestURI is set to null ( java realms require us to try and access a protected resource, then get transferred to the login page ).
I came up with the solution to post the login details to a servlet. This would look a little like this: http://localhost:8080/mysite/LoginProxy?j_username=administrator&j_password=midletsite&j_forward=/index.jsp My program would then alter the Request object, changing the requestURI field with the j_forward parameter. I couldn't get access to any setter properties of the request, so I subclasses HttpServletRequestWrapper and overrode the getRequestURI method to return the j_forward parameter's value if the requestURI was null. I then call dispatchRequest() with my HttpServletRequestWrapper object. However this does not work. I get the error The requested resource (/mysite/j_security_check) is not available. However, if I simply put in http://localhost:8080/mysite/j_security_check, I do hit the login target. I expect this has something to do with the way that the request comes to tomcat. Maybe it checks for j_security_check when it checks whether my Proxy can be accessed. I'd hoped that it was some kind of accessible virtual page that could be accessed. Is my line of investigation doomed? Here's the code exerpt.... public void service ( HttpServletRequest a_Request, HttpServletResponse a_Response ) throws java.io.IOException, ServletException /* ----------------------------------------------------------------------------- 20 July 03 Ben Jessel Created. ----------------------------------------------------------------------------- */ { // Method Location final String ksLocation = "service ( HttpServletRequest a_Request, HttpServletResponse a_Response )"; // Get the map of parameters from this request. Map paramMap = a_Request.getParameterMap(); String sUserName = a_Request.getParameter ( c_ksUserNameParam ); String sPassword = a_Request.getParameter ( c_ksPasswordParam ); String sForward = a_Request.getParameter ( c_ksForwardParam ); LoginRequest tst = new LoginRequest ( a_Request, sForward ) ; tst.setAttribute("j_username", sUserName ); tst.setAttribute("j_password", sPassword ); System.out.println( tst.getContextPath() + "/j_security_check?j_username=" + sUserName + "&j_password=" + sPassword ); // Get the RequestDispatcher RequestDispatcher rd = getServletConfig().getServletContext().getRequestDispatcher( tst.getContextPath() + "/j_security_check?j_username=" + sUserName + "&j_password=" + sPassword ); rd.forward(tst, a_Response); } } class LoginRequest extends HttpServletRequestWrapper { String m_sForwardURI = ""; String requestURI = "/midletsite/index.jsp"; /** * @param arg0 */ public LoginRequest(HttpServletRequest arg0) { super(arg0); } /** * @param arg0 */ public LoginRequest(HttpServletRequest arg0, String a_sForwardURI ) { super(arg0); m_sForwardURI = a_sForwardURI; } public String getRequestURI() { return ( ( super.getRequestURI()==null ) || ( getRequestURI().trim().length()==0 ) ) ? m_sForwardURI : super.getRequestURI(); } __________________________________________________________________________ Join Freeserve http://www.freeserve.com/time/ Winner of the 2003 Internet Service Providers' Association awards for Best Unmetered ISP and Best Consumer Application. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
