Another Problem with servlet mapping

[pawan <pa...@apar.com>]

Hi,

Tomcat 4.1.24, Win 2000, Oracle 8i

here is my directory structure :-

shyam(which is my context root)
|
|___jsp
|       |____ams
|               |_____<my files in this directory>
|
|___servlets

now let say my url is:

http://localhost:8080/shyam/jsp/ams/viewAccount.jsp

This jsp has a form which actually sends this request to
viewAccountDetail.js... I am using this action :-

action="<%= request.getContextPath()
%>/manageAccount/viewAccountDetail.jsp">

now here "manageAccount" is just a keyword which i am using for url mapping
in my web.xml file....and its calling my controller servlet....which is
working fine. Now this servlet creates an instance of my bean
"AccountData.java" and then i have to forward this request to the actual
"viewAccountDetail.jsp"

http://localhost:8080/shyam/jsp/ams/viewAccountDetails.jsp

to forward i am using :

req.getRequestDispatcher("/jsp/ams/viewAccountDetail.jsp").forward(req,
resp);

Its finding the targeted page as i can see some console output but the url
in the browser doesn't change. It remains
http://localhost:8080/shyam/manageAccount/viewAccountDetail.jsp

Because of this my page is not able to load any images or style sheet.... so
how can i change actual url in the browser address bar????


Please show me a way or an alternate way to achieve this MVC.

Thanks In Advance

Pawan

As it should.  The browser doesn't know or care about what you've done with
a rd.forward :).

If you need to change the actual URL in the browser, then use
response.sendRedirect.  However, for MVC, this is bad-practice.  You should
set your img and stylesheet references to be absolute (e.g.
<img src="<%= request.getContextPath() %>/images/foo.jpg>">).

The (simplified) rule for URLs is:
1)  If it starts with http://server/path then use it verbatum.
2)  Otherwise if it starts with '/....', the use
http://<server>:<port>/....., where <server> and (if not the default port,
port) are copied from the current page.
3) Otherwise, take the URL of the current page, strip off every thing from
the final '/' character, and concatinate the given URL onto it.
