Redirection in JSP

Dear All,
I have the following requirement and I am not able to find a solution.
I have four jsp files called one.jsp, two.jsp, three.jsp, four.jsp.
On clicking the submit button in one.jsp, the request goes to two.jsp. two.jsp will do some processing and will redirect to three.jsp after passing some condition. If the condition fails, the request ends there. Now my requirement is to display the four.jsp if the condition fails, after waiting for about 30 seconds. 30 seconds is because it is assumed that it will take a max of 30 seconds to check the candition. The catch here is that two.jsp is not my control and its somewhere in a different web server.
I will be really thankful if anybody can give some idea. Is this really possible ????

Ramya,
use URL and URLConnection to connect to the two.jsp which is in some
other server, get the response and on the basis of the response do
the further operations.
Regards

How to redirect a JSP page after the session is killed

Hello!
I am quite new to JSP. I have a question about how to redirect a jsp page after the session is killed. Could anyone help?
thanks a lot in advance!

You can't, directly. There's no connection betweenthe server and browser.
even after invalidating the session. we can do it
directly using the statement
response.sendRedirect("....");
or we can use the meta refresh tag.if session is invalidated and if we try to do response.sendRedirect(".. ") it throws IllegalStateException

Redirect from JSP to JSP

Hi,
I want to know how i can redirect a page from a jsp page. It's a simple question but i'm beginnner...
Best regards...

This works me perfectly:
your webapp can be also structured to directories.
for normal visible link:
<a href="<%= response.encodeURL(../index.jsp")%">">back to index</a>
for automatic redirection (like jsp:forward):
response.sendRedirect(response.encodeRedirectURL("../index.jsp"));
NOTE:
URLs are wrapped by response.encode*URL() methods to allow URL rewriting in case when cookies are disabled by client.

Redirect from jsp bean to jsp or html page

I am facing a problem in redirecting to a jsp page from jsp bean
How do i redirect from jsp bean to any other page like jsp or html.
[email protected]

Hi
The solution you suggested we tried it long before only but it is not feasible for us as we have to implement it in all web pages which are in thousands.
My need is like this.
We have given specific time to each of our registered user , as user logs to our portal we calculate session time in bean and as he logs out is new time gets updated. (its like dial up connection)
Now what happens consider user has left only 10 minutes balance, I can calculate and keep track for his time in bean.Now as the time becomes zero I want to redirect him to home page.
As u said i can get return value zero for bean and can do it ,but our webpages are near about thousands.

Redirection to JSP page from Applet not working...

Hello,
I have some JSP pages that obtain information and set session variables. Once they have gotten the information, they call an applet to perform some processing, then the applet redirects back to the calling page. My problem is that when the applet redirects using
getAppletContext().showDocument(reportJspUrl, "_self");
it seems to be unable to see the session variables that I set in the beginning - consequently I am getting a faulty session timeout error. Has anyone seen this problem? I don't understand why it is happening. It seems that when the applet causes the page to be shown, the page should be able to see the session since it is in the same browser, even in the same frame of the browser.
Thank you for your help in advance.
Ali

Have you tried getting the session in the jsp with req.getSession(false) and confirming that the session returned is not null.

WebCenter RIDC DataControl always redirects any JSP page to login page

Hi
I have created a Data Control which connects to the UCM data repository and created a plain JSP page to return the results. I have used RIDC Connection settings and authentication details are tested and they look fine to me.
RIDC Socket Type: socket
Server Host Name: localhost
Content Server Listener Port: 4444
Authentication: Identity Propagation
Username/Password: weblogic/weblogic
But when ever I ran the test JSP page, it always redirects the page to login page. For example: http://127.0.0.1:7101/RIDCDocumentManager-Portal-context-root/faces/oracle/webcenter/portalapp/pages/login.jsp
Any suggestions?
Thanks
Khad

Thanks for the details Yannick. The home.jspx works as expected. Thanks for that.
I have got one more question on passing username through RIDC api.
Via RIDC, how can I pass the UserName to the IdcContext object dynamically [IdcContext userContext = new IdcContext("weblogic");]. I mean how to retrieve the logged in user name for the person requesting the page instead of hardcoding the username. Below is the code fragment:
// create the manager
IdcClientManager manager = new IdcClientManager();
// build a client that will communicate using the intradoc protocol
IdcClient idcClient = manager.createClient("idc://localhost:4444");
// get the config object and set properties
idcClient.getConfig().setSocketTimeout(30000); // 30 seconds
idcClient.getConfig().setConnectionSize(20); // 20 connections
//create a simple identity with no password (for idc:// urls)
IdcContext userContext = new IdcContext("weblogic");
// create an identity with a password
//IdcContext userPasswordContext = new IdcContext("weblogic", "idc");
// get the binder
DataBinder binder = idcClient.createBinder();
// populate the binder with the parameters
binder.putLocal("IdcService", "GET_SEARCH_RESULTS");
//binder.putLocal("QueryText", parameter);
parameter = getInputParameter();
binder.putLocal("QueryText", "<qsch>" + parameter + "</qsch>");
binder.putLocal("ResultCount", "20");
// execute the request
ServiceResponse response = idcClient.sendRequest(userContext, binder);
// get the binder
DataBinder serverBinder = response.getResponseAsBinder();
DataResultSet resultSet = serverBinder.getResultSet("SearchResults");
// loop over the results
for (DataObject dataObject : resultSet.getRows())
dataObject.get("dDocTitle");
dataObject.get("dDocAuthor");
dataObject.get("dInDate");
System.out.println("Title is: " + dataObject.get("dDocTitle"));
System.out.println("Author is: " + dataObject.get("dDocAuthor"));
System.out.println("Author is: " + dataObject.get("dInDate"));
}

Help with 301 redirect code - jsp in url

I'm trying to set a 301 redirect in my jsp code (this is tomcat btw) using this:
<%
response.setContentType("text/html");
response.setDateHeader("Expires", 0);
response.setHeader("Location", "http://www.mysite.com/record/pleasehelpme /helpmeheretoo");
response.setStatus(301);
%>
the pleasehelpme and helpmeheretoo need to use variable values i get from mysql which i would normally express in the application like
<%=(((Recordset1_data = Recordset1.getObject("avariable"))==null || Recordset1.wasNull())?"":Recordset1_data)%>
so what do i need to stick in those parts of the path in the url?
it works great redirecting to a flat url but I need those variable (well, that's the point of this anyway).
sticking the <%= recordset stuff %> is breaking since it's like a tag in a tag (i guess) - have tried variations on sticking println around (String)Recordset1.getObject("avariable") like
"http://www.mysite.com/record/(out.println(String)Recordset1.getObject("avariable"))"
and variations with curly braces and semicolons and everything but i keep getting
Syntax error on token "avalue", invalid AssignmentOperator
errors. (i'm obviously tring to figure out just one variable before i stick both in the path while i get this figured out).
can someone hit me with a clue stick?

And then finally I found a .php option (which I saved in my root directory)
<?php
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.downtoearthlandscaping.ca/#!/page_Home");
?>
I
This works, does your server support php?
You don't need:
header("HTTP/1.1 301 Moved Permanently");
Just this:
<?php
header("Location: http://www.downtoearthlandscaping.ca/#!/page_Home");
?>
Saved as index.php
The server will find index.php and the first page should be displayed.

Losing beans after redirecting in jsp

hi , everybody
I am new in web programming.
this is my jsp :
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<bean:write name="mess" property="text"/><br>
your username: <bean:write name="user" property="name"/><br>
your password: <bean:write name="user" property="password"/><br>
To add the book to Database click <a href="/pages/BookAdding.jsp">here</a><br>
To rent the book click <a href="pages/RentBook.jsp">here</a>
</body>
</html>
<as you can see here i have 2 javabeans 1-mess 2-user
and 2 possibilities for redirection (<a href....>)
after redirection my beans are null....
somebody can help me please???
thanks

First of all, the taglib declaration should be on the top of you jsp.
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<bean:write name="mess" property="text"/><br>
your username: <bean:write name="user" property="name"/><br>
your password: <bean:write name="user" property="password"/><br>
To add the book to Database click <a href="/pages/BookAdding.jsp">here</a><br>
To rent the book click <a href="pages/RentBook.jsp">here</a>
</body>
</html>The beans are lost because they have either a page or a request scope.
To avoid this, put them in the session scope instead.

Redirecting in JSP

Hi all,
I have a file named session.jsp which i use to check the session value. If a session value is null, i want to redirect the user to login page. The Code for session.jsp is as:
<%
if((session.getValue("name") == null))
{ %>
<jsp:forward page ="index.jsp" />
<% } %>
Now I include this file in a new jsp file named xyz.jsp. Now i access xyz.jsp without logging in. So the session contains null in name variable (I have printed this value too and it contains null). But I am not redirected to index.jsp. I also tried using response.sendRedirect("index.jsp") but i m not redirected.
I am using Tomcat server
Secondly, I have a file named header.jsp Now whenever i change this file, i have to once again save all the files which use header.jsp ( i use include directive). Is there some method of avoiding this.
Thanks
Gagan Arora

if((session.getValue("name") == null))
try
if((session.getAttribute("name") == null))
nurettinThanks for ur support but even this doesnt works. I now recieve a Error message :500
IOExecption: Attemp to clear a buffer thats already been flushed

Redirecting with jsp

hi.
i need to check for the session on one of the page which located in the frame and if there is no session to redirect user to some page, which must be on the _top level of frameset, similar thing is in regular hyperlink people use:
target="_top" is it possible to do it with jsp response.sendRedirect? (response.sendRedirect("/index.jsp"); )
thanks in advance

frame is a HTML idea, so HTTP(and HTTP ridirection) has no idea about it. One solution is to use javascript.
You can also use jsp in the page that defines teh framesets. It can check for the session, and if necessary loads the new page rather than using the framset.
You may also consider not using frames as much as possible. Rather, you can use jsp templates which uses table to structure different parts of the page and use include(staic/dyn as needed) to construct the page.

Change protocol when redirecting a request for a servlet to jsp

Hello,
In my servlet, There is a line of code:
getServletConfig().getServletContext().getRequestDispatcher("/page.jsp").forward(request,response);
My question is: I'd like to change the current protocol (like http) to new protocol (like https) or versa vista before my servlet executes the above line.
Is this possible to implement that? If so, how can I do it?
If not implement, Is there any ways to convert back or forward between http and https protocols in java, servlet or jsp?
I did try to use window.location.href="protocol://myserver/..." in javascript to redirect the jsp page to the right protocol, but the session for the browser was lost, and the jsp page ran into infinite loop.
Thanks in advance for any helps.
Mike.

if (!request.isSecure()) response.sendRedirect("https://me.com/page.jsp");
(or visa versa)

How to redirect the to the file outside the context from jsp

Hello Everybody,
I am trying to redirect using jsp to the file available physically in the server machine out side the application.
How can I do it..
Thanks
Saikrishna

Write a servlet which takes the file ID as parameter, reads the file from the disk and writes it to the outputstream of the response. Finally redirect to that servlet with the file ID as parameter.
You can find here an example of such a FileServlet: [http://balusc.blogspot.com/2007/07/fileservlet.html].
