Question

Answer 1

+2 A:

These files are loaded from the client which will interpret relative links to the base URL. If you are internally forwarding a request to a different servlet, you have to pay attention to what the client thinks is the URL. It may be necessary to switch to absolute links or generate a base tag.

These types of problems are easily seen client-side debugging with Firebug or Safari for example. You're probably getting 404s on the css and javascript links.

Answer 2

A:

I'd examine the server logs to find out the URLs that are being requested by the browser when it loads this page and its dependents.

how to examine the server logs ?

That depends on what webserver you are running.

Answer 3

+2 A:

Use <c:url> to resolve absolute URIs (this example assumes that ".." in your code is a webapp root):

<%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
<HTML> 
 <head> 
 <link rel="stylesheet" type="text/css" href="<c:url value = "/CSS/home.css" />" /> 
 <link rel="stylesheet" type="text/css" href="<c:url value = "/CSS/left.css" />" /> 
 <script type="text/javascript" src="<c:url value = "/js/friend_request.js"></script>  

 </head> 
 <body> 
 <div class="menu"> 
 <form name="search_form" method="post"> 
<table id="menutabel" class="color"> 
  <tr> 
   <td class="alt"><A class="one"HREF="<c:url value = "/home.jsp" />">Home</A></td> 
   <td class="alt" ><A class="one"HREF="<c:url value = "/HTML/falbum.html" />">My Album</A></td> 
   <td class="alt" ><A class="one"HREF="<c:url value = "/HTML/MyDiary.html" />">My Diary</A></td> 
   <td class="alt" ><A class="one"HREF="<c:url value = "/HTML/MyFriends.html" />">Myfriends</A></td> 
      </tr> 
    </table> 
 </form> 
 </body> 
 </html>

(+1) <c:url is the way to do it

All those `c:url`'s in the JSP is a bit messy. But another major advantage of `c:url` is that it automatically does the "URL rewriting" for the case the session plays a role in the whole story and the client has cookies disabled. If this is the case, I would go for it as well.

Answer 4

+2 A:

Make use of the HTML <base> tag. It denotes the base URL of all relative URL's used in the final HTML output. If you set it with HttpServletRequest#getContextPath(), then ALL links in your page will be relative to the http://example.com/contextname URL, which is http://localhost:8080/Projectname in your case.

<!doctype html>
<html lang="en">
    <head>
        <base href="${pageContext.request.contextPath}">
        <link rel="stylesheet" type="text/css" href="css/style.css">
        <script type="text/javascript" src="js/script.js"></script>
    </head>
    <body>
        <ul>
            <li><a href="html/page.html">HTML page</a></li>
            <li><a href="jsp/page.jsp">JSP page</a></li>
        </ul>
    </body>
</html>

Note that you should not start the relative URL's with /, otherwise they will lead to the domain root, e.g. http://example.com/yourlink.

By the way, links doesn't need to be placed inside a form. Also HTML tables ought to be used for tabular data only, not for other content. Learn semantic HTML as well.

(+1) didn't know that tag existed.. :)

Bozho 2009-12-30 19:52:15

thank for the tip, i was just trying to create a navigation bar which looks aligned perfectly, for this purpose i used the table. Now will work on the hint u provided.
