Strange response.sendRedirect() problem

[Stan Ca]

Hello all,

First off, I'd like to say that I did search these forums for a solution to my problem, but none seemed similar to mine. Also, I'm using Oracle Application Server 10.1.3 (which uses a modified Apache HTTP server), and the problem might just as well lie there. Anyway, I though I'd ask here to see if anyone has a clue as to what might be the problem.

When users arrive at the web app, index.jsp is loaded, which is a page containing several frames. They enter their user name and password here, and press the "login" button. The data is posted to a page called LoginAction.jsp. This checks the request data, and then performs a sendRedirect. However, the page doesn't seem to be redirected (or cannot be found).

This is the redirect code in LoginAction.jsp:

  
Collection roles = userSession.getRoles(user.getId());
if(roles != null && roles.size() > 0) {
  session.setAttribute("roles", roles);
  System.out.println(new Timestamp(System.currentTimeMillis()) + 
         "\t Web user " + username.toUpperCase() + " successfully logged in");
  if(new JspHelper().showUserNotification(user.getId())) {
    redirectUrl = request.getContextPath() +
"/UserMessage.jsp" +
"?uid=" + user.getId();
  } else {
    // Login was successful, so redirect the user based on his/her permissions
    redirectUrl = request.getContextPath() +
        "/MainOverview.jsp" +
"?uid=" + user.getId();
  }
  response.sendRedirect(redirectUrl);
  return;
} else {
  session.setAttribute("errorMessage", "User " + user.getLogin() + " has no roles yet.");
  response.sendRedirect(redirectUrl);
  return;
}

As you can see, I do have a "return;" behind the sendRedirect(). Now, when I login with IE, I get an "Action canceled" page, stating IE was "unable to link the web page you requested". When I use Mozilla, nothing happens after pressing the button.

Now, when using a <jsp:forward>, it does work. You may call me lazy, but I used the sendRedirect throughout several web apps, and I would like to get this working.

Something else I should mention... We're behind a firewall here. The server is inside the LAN (obviously), and when I browse to it from within the LAN, it works just fine. When I use an outside line, and enter through the firewall to access the web app, the sendRedirect fails.

Reading over this post, it's probably not the code that's at fault, but some setting somewhere... On the http server or on the firewall...

Anyone have a clue?
Also, would you advise me to use <jsp:forward> instead of sendRedirect?

Thanks,

sca

Found it.

Some silly setting in the httpd.conf configuration file of the Apache server was the cause. Namely UseCanonicalName, which defaults to 'On' but should be 'Off' in this case.

Moved to the Oracle forum as this turned out to be a configuration problem.
Thanks for posting back.

Welcome to JavaRanch!

We're pleased to have you here with us in the Oracle/OAS forum, but there are a few rules that need to be followed, and one is that proper names are required. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

You can change it here

Owkay. Changed.

[Bear Bibeault]

Sorry, not owkay.

Please read Ben's instructions once more and change your display name to a first name and a last name. Initials for a last name are not acceptable.

Okay, sorry, merely skimmed the contents of that name policy.
Never meant to be obtrusive (or offensive or whatever).

Anyway, changed the name again. Please review it to see whether it is "real" enough. Unfortunately, the name in the posts doesn't seem to get updated (though the topic starter name is correct). Need I create a new login?

EDIT: never mind, the display name in the posts did change too.
EDIT2: slightly changed name again; sorry for that.
