helping hand required

i'm developing a web app using struts and jsp. jsp are for presentation and struts as controller.
what i need is to redirect to a page soon after the request is completed.
E.g. if user wants to change his password then next page should display a confirmation message and now page must be redirected (to the home or somthing else as needed by situation) here in this example it must be the page where the change password link is selected.
the best example to discribe what i want is whenever we post or reply to some thread then a message is displayed and we are redirected to the same therad again, jsut like this i want to implement in my app.
please suggest me how to implement it??
what i tried :
<jsp:forward -- this happens at sever i want to display a message and then move to another page!!
even i tried to use scriptlet response.sendRedirect("someUrl"); but i think using scriptlet in jsp is not good practice!!

beans are used to retrive data from browser.

please help

Using HTML (which is I presume what your web app spits out), use the meta tag to redirect a user. An example:
Tryit Editor v1.4

Re: helping hand required

that was really helpful! but the problem is that i'm using struts-tiles to create pages. every time i want to display a page i just create that page and then insert layout page into that and provides the necessary details which are needed to name sections to be displayed!
here is the layout.jsp

Code JSP:

<%@taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>
<%@taglib prefix="tiles" uri="http://struts.apache.org/tags-tiles" %>
 
<html>
    <head>
        <title>Rainbow Entertainment<tiles:getAsString name="subtitle"/></title>
    </head>
    <body bgcolor="white">
    <center><table border="0" cellspacing="0" cellpadding="0" width="860">
            <tr height="71">
                <td align="center" valign="center" width="160" height="71">
                    <img src="<c:url value="/images/rainbow_Entertainment.jpg"/>"
                         alt="Rainbow Entertainment logo">
                </td>
                <td bgcolor="#CCCCFF" align="center" valign="center" width="700" height="71">
                    <c:set var="subtitle"><tiles:getAsString name="subtitle"/></c:set>
                    <jsp:include page="/WEB-INF/layout/banner.jsp">
                        <jsp:param name="subtitle" value="${subtitle}"/>
                    </jsp:include>
 
                </td>
            </tr>
            <tr valign="top">
                <td bgcolor="#CCCCFF" width="160" align="left">
                    <jsp:include page="/WEB-INF/layout/navigation.jsp"/>
                </td>
                <td width="700" align="left">
                    <div style="margin-top: 0.1in;margin-left: 0.1in;margin-bottom: 0.1in;margin-right: 0.1in">
                        <tiles:insert attribute="body" />
                    </div>
                </td>
            </tr>
            <tr>
                <td width="160"></td>
                <td align="right" width="700">
                    Copyright © 2011 Rainbow Entertainment
                </td>
            </tr>
        </table></center>
 
 
    </body>
</html>

Re: helping hand required

i just don't understand that
in my app if i click a link once it works fine but if it is clicked twice then an error page is displayed stating that resource not found, the most intresting thing is that the path to resource in error message was never provided in the link!!
E.g link is set to "views/admin/home.jsp" then it works for the first time but if it is clicked twice then then error genrated will show "views/admin/views/admin/home.jsp" not found!!
if really confused why this is happening!!
please hep!!
