How to remember previous page in a JSP page that's reloaded

I have a JSP page where i want a "back" link that brings me back to the previous page. The problem is, some actions on this page will call a servlet that reloads my page, so using history.back() brings me back to the previous version of the same page.
What is a good way to solve this in a servlet/JSP application?

I just wrote a simple bean with a few methods that i frequently use.
the bean is session scope, and you just call something like
setCurrentPagePath(), and you build your link up by calling getCurrentPagePath()
before settings the new one.

How do i use Connection pool in JSP pages

Hey everyone,
I am using a connection pool in my web application. I am using DbConnectionBroker from Javaexchange.com. It has a class that creates a connection pool available for the servlets. I am trying to figure out that how to use connection pool within the JSP pages if I want to connect to the database. In the servlets i am using DBConnectionBroker pool = (DbConnectionBroker) getServletContext().getAttribute("dbPool") to get database connection. How Can i use this in JSP page to get a db connection.
Thanks

If the reference to the connection pool is already stored as an ServletContex attribute, try:
<jsp:useBean id="dbPool" scope="application" class="com.javaexchange.dbConnectionBroker" />
<%
Connection con = dbPool.getConnection();
%>

Opening a seeded OAF page from custom JSP page.

Hi All,
We have requirement to open a seeded OAF page from custom JSP page.
When we try to open URL of an OAF page after passing URL input parameters, we are always getting following error:
'You have insufficient privileges for the current operation. Please contact your System Administrator.'
On directly accessing the seeded OAF page, its encoding all the input parameters passed in URL. Also some more encoded parameters are getting added to the URL dynamically.
Is there any standard way exists to invoke seeded OAF pages without passing encrypted parameters to it? Also where can we get more details about
encrypting OAF URL parameters.
Any pointers would be appreciated.
Thanks in advance!

Embed a jsf page in a jsp page -

Is there some way to included a jsf page inside a jsp page and code form action correctly ?
In my JSP page I have the following:
<jsp:include page="../user/unMapTrans.faces" />
The page loads correctly, however, when I submit the form I get "Cannot find FacesContext"
The way I'm coding form action in my JSP <form method="POST" action="../common/controller.jsp">
The way JSF generates <form id="utform" method="post" action="/riskdb/user/unMapTrans.jsp" enctype="application/x-www-form-urlencoded">
The JSP is another location than the JSF being called... http://localhost:7001/riskdb/common/controller.jsp

Is that maybe a browser memory auto-complete thing? It works on Netscape 7.2. But no, it's not a browser auto-complete thing (does NS have that? IE does... either way, I would've disabled that). It's definitely a Javascript trick, I'm sure of that. I know I haven't sent mail to all people in my address book from my work PC, but it doesn't stop them from showing in the list as I type...
Unless there is a special HTML tag option or browser extension that I've never heard of that allows you to supply a set of values to a text input field for auto-completion (as opposed to the browser remembering what was typed).

How to call a report from a jsp page

Hi
1) Can anyone please tell me how can i view Discoverer report from a jsp page instead of opening it directly thru plus/viewer.
2) Please clarify do i need to install Infrastructure and OID for it.
Please advice.
Thanks

You need the AS infrastructure if you want to use connections. If you do not intend using connections, you do not require the infrastructure.
Note that you cannot pass in passwords in the URL any longer. You do not need to pass passwords if you pass in a Discoverer connection id (but then again - if you don't use connections, then you do need to still pass in the connection information - username, password, database, language, EUL)
I have a post on my blog that describes how to pass a password using an HTML Form submit - http://oraclebi.blogspot.com/2005/08/passing-password-to-viewer.html

How can I pass a variable value from first jsp page to thired jsp page

In my program ,threr are three jsp pages . I want the first pages's variable value in to thired page .How can I acess.
I used the request.getparameter() ,but when I print the value , null value is getting .

request parameters only last for one request.
To save them longer than that you need to save them somewhere.
Couple of alternatives
1 - store them to session
session.setAttribute("username", request.getParameter("username");
2 - create a hidden field on page 2 and store the value from page 1 there. When you submit page2, you can get it on page3 with request.getParameter again.
<input type="hidden" name="username" value="<%= request.getParameter("username") %>">

How can I link to a jsp page from another jsp page within websphere portal?

Afternoon all,
I have a websphere portlet which displays a jsp page. I want to put a hyperlink on the jsp page which when clicked will open another jsp page.
Does anyone know how to do this?
Thanks,
Alex

The anchor tag is the correct one for generating clickable links.
<jsp:forward> is for transferring control at the server end. Its when you decide to change which page you want to show the user. ie check user is logged in. If not then forward them to login page, else display current page.
I tried that. It does open the jsp page
but the place and page links in the portal theme get screwed up.Whats mucked up about them? Do they point where they shouldn't?
You might try using a <base> tag to set where relative links are resolved from.

Hi,
so what source address of js file i have to give in jsp page.....in your case you can use below include command
<jsp:include page="script/test.js" /> // here test.js is your .js file nameGenerally we need to place all jsp and js files under "jdevhome\jdev\myhtml\OA_HTML". In this case you can use
<jsp:include page="test.js" /> // here test.js is your .js file nameor
<%@include file="test.js" %> // here test.js is your .js file nameregards,

How to configure .ocx file in a JSP page

Hi i am doing a project which involves data retrival from a Swipe card. I am going to retrive the id from the card and this data has to be sent to a JSP page. After retriving the ID from the card, we access the database and retrieve all the information required. The latter part is done thru JSP, STRUTS and EJB.
The swipe card reader is programmed in VC++ and an OCX file is created. Now i need to know how to configure this OCX file into Java technology thru web.
If anyone could help me, i'll be more thankful.
