Auto log in from applet to web app.

Question

I'm trying to allow a user to jump from an applet to a web app.
The applet code I'm pretty sure is complete. It creates a URL and then calls container().getAppletContext().showDocument(new URL(path),name);
This opens a browser and seems to be sending the correct URL.
What I have done is send it to a URL like /appName/JumpFromApplet
Then I have created a filter in the web app to catch anything of that format.
The doFilter method is being executed and it the if statement is catching it appropriately.
But when the browser opens up the url is just http://localhost:9080/ with a page cannot be found. I'm not sure what I'm doing wrong. Here is the appropriate code. Am I way off base?
private static final String LOGGEDIN_URL = "login.do";
//inside doFilter method
Object o = httpRequest.getSession().getAttribute("LOGGEDIN");
if(o == null && url != null
         && url.indexOf(JUMP) > 0) {
     config.getServletContext().getRequestDispatcher(LOGGEDIN_URL).forward(request, response);
}else {
     chain.doFilter(request, response);
}edit:
This is basically the same code as in my LoginFilter, I just changed the URL and of course the if statement.

Answer 1

hmmm, strange. I added the code to the loginFilter as an else if.
If I enter the url in the browser that the filter is suppose to be catching then it works just fine.
If I jump from the applet it does not... but when stepping through the code in both instances it looks like everything is the same?
the else if is what is executed.
public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {
    HttpServletRequest httpRequest = (HttpServletRequest) request;
    Object o = httpRequest.getSession().getAttribute("LOGGEDIN");
    String url = httpRequest.getRequestURL().toString();
    if (o != null
            || (url != null && (url.indexOf(LOGIN_URL) > 0
                    || url.indexOf(LOGIN_FORM_URL) > 0
                    || url.indexOf(EXTERNAL_LOGIN_URL) > 0
                    || url.indexOf(EXTERNAL_LOGIN_FORM_URL) > 0
                    || url.indexOf("images") > 0 || url.indexOf(services) > 0))) {
        chain.doFilter(request, response);
        return;
    }else if(o == null && url != null
              && url.indexOf(JUMP) > 0) {
          config.getServletContext().getRequestDispatcher("/" + JUMP_URL).forward(request, response);
        return;
    config.getServletContext().getRequestDispatcher("/" + LOGIN_FORM_URL)
            .forward(request, response);
