Simulate doNothing(minutes) in JSP

I am trying to simulate browser behaviour during extensive server processing. To do this I have a JSP which I pass a parameter of how long to sleep, so the JSP is still processing, but nothing is returned to the browser.
What is the best way of doing this? At the moment I am using a loop that keeps using Calendar.getInstance(), but obviously this eats up my system resources.
Suggestions with code really appreciated :)

Thanks - this works perfectly.
I didn't think of using Thread.sleep() because I didn't think it could be that simple.

Optimal XP Configuration for Workshop

We've put Workshop 8.1 SP1 on WinXP Pro workstations (2.3GHZ, 1Gb RAM, 20Gb HD). We used them for our week of BEA Portal training. The performance was miserable - it took minutes for jsps to compile and open for debugging - and they locked up or crashed at least twice a day. After class, we upgraded to SP2 (we couldn't during class to avoid conflict with class examples) but have seen no appreciable difference in stability or performance. BEA provides "minimum" requirements (PIII 700Mhz, 1 Gb RAM), which we exceed. Before I go essentially sell my first born to get our PC guys to get me some newer PC hardware (we buy Dell OptiPlex as our corporate standard - can get 3.2GHz w/ 2Gb RAM), are there other tweaks which may help? I've received internal suggestions to possibly get the Dell Precision WinXP workstation to get:
* A bigger, faster disk (70 Gb, 7200rpm SATA) and create a much bigger swap file (15-20Gb).
* A dual proc XP box
But before we sink $3,500 into these, would this help my problem? Or is Workbench just slow and unreliable?

Mike,
Have you tried running with SP2 yet? You should notice perf
improvements with SP2.

Problem in setting up schedule push

Hi every body,
I have a multimaster advance replication environment and we have less than 10 transaction per day. I am not sure what is the correct set up for my case.Could you please help me?
My first question is:I want to propagate data as soon as possible like sync if I setup the schedule push to propagate transaction every 5 seconds as below
BEGIN
DBMS_DEFER_SYS.SCHEDULE_PUSH(
destination => 'orc2',
interval => 'SYSDATE + (5/60*60*24)',
next_date => SYSDATE,
parallelism => 1,
delay_seconds => 10);
END;
is it correct approach?
in other hand ,book(I mean Advance Replication) has written that for simulating continuous push we should setup it as below so it will propagate transaction every 1 minute.
My second question is:I know interval >= 'SYSDATE + (1/144)' means every 10 minutes a job will start and delay_seconds => 1200 means each job remain aware for 20 minutes,
but I can't understand why it can simulate 1 minute propagation? anybody knows?
BEGIN
DBMS_DEFER_SYS.SCHEDULE_PUSH(
destination => 'orc2',
interval => 'SYSDATE + (1/144)',
next_date => SYSDATE,
parallelism => 1,
execution_second >= 1500,
delay_seconds => 1200);
END;
My thrid question is :Which of the above setups is a better solution for my environment?I mean 5 second interval (interval => 'SYSDATE + (5/60*60*24)') + delay_second = 10 and parallel or 10 minute interval (interval => 'SYSDATE + (1/144)') + delay_second = 1200 and parallel + execution_second =>1500)
Thank you in advance.
Mery

With a "delay" of 20minutes, the push job will "hang around" for 20minutes waiting for new transactions. If it receives no new transactions to push, it will go to sleep. However, with the job interval at 1minute, it will "wake up" one minute later and push
transactions that were created in that last 1 minute. Again, it will "hang around" for the next 20minutes.
This is what I see from the 9i documentation (for advanced replication not using streams, I find the 8i and 9i documentation better
than the 10g documentation)
Delay Seconds
Though not directly a performance mechanism, properly configuring the delay_seconds parameter can give you greater control over the timing of your propagation of deferred transactions.
When you are pushing deferred transactions, you set the delay_seconds parameter in the SCHEDULE_PUSH procedure or the PUSH function. When you are purging deferred transactions, you set the delay_seconds parameter in the SCHEDULE_PURGE procedure or the PURGE function. These procedures and functions are in the DBMS_DEFER_SYS package.
The delay_seconds parameter controls how long a job remains aware of the deferred transaction queue. The effects of the delay_seconds parameter can best be illustrated with the following two examples:
delay_seconds = 0 (default)
If a scheduled job with a 60 minute interval wakes up at 2:30 pm and checks the deferred transaction queue, then any existing deferred transactions are propagated. The propagation takes 2 minutes and therefore the job is complete at 2:32 pm.
If a deferred transaction enters the queue at 2:34 pm, then the deferred transaction is not propagated because the job is complete. In this scenario, the deferred transaction will be propagated at 3:30 pm.
delay_seconds = 300
If a scheduled job with a 60 minute interval wakes up at 2:30 pm and checks the deferred transaction queue, then any existing deferred transactions are propagated. The propagation takes 2 minutes and therefore the job is complete at 2:32 pm.
If a deferred transaction enters the queue at 2:34 pm, then the deferred transaction is propagated because the job remains aware of the deferred transaction queue for 300 seconds (5 minutes) after the job has completed propagating whatever was in the queue. In this scenario, the deferred transaction is propagated at 2:34 pm.
Why not just set the job to execute more often? Starting and stopping the job has a greater amount of overhead than starting the job and keeping it aware for a set period of time. In addition to decreasing the overhead associated with starting and stopping these jobs, using the delay_seconds parameter can reduce the amount of redo logging required to support scheduled jobs.
As with most performance features, there is a point of diminishing returns. Keep the length of the delay_seconds parameter in check for the following reasons:
Parallel Propagation: Each parallel process that is used when pushing the deferred transaction queue is not available for other parallel activities until the propagation job is complete. A long delay_seconds value may keep the parallel process unavailable for other operations. To use parallel propagation, you set the parallelism parameter to 1 or higher in the SCHEDULE_PUSH procedure or the PUSH function.
Serial Propagation: If you are using serial propagation (not parallel propagation), then the delay_seconds value causes the open session to "sleep" for the entire length of the delay, providing none of the benefits earlier described. To use serial propagation, you set the parallelism parameter to 0 (zero) in the SCHEDULE_PUSH procedure or the PUSH function.
Precise Purge: If you specify the purge_method_precise method when using the DBMS_DEFER_SYS.PURGE procedure and you have defined a large delay_seconds value, then you may experience performance degradation when performing the specified purge. Using purge_method_precise is more expensive than the alternative (purge_method_quick), but it ensures that the deferred transactions and procedure calls are purged after they have been successfully pushed.
As a general rule of thumb, there are few viewable benefits of setting the delay_seconds parameter to a value greater than 20 minutes (which is 1200 seconds for the parameter setting).
Additionally, if you are using serial propagation by setting the parallelism parameter to 0, then you probably do not want to set a large delay_seconds value. Unlike parallel propagation, serial propagation only checks the queue after the duration of the delay_seconds value has elapsed. If you use serial propagation and set delay_seconds to 20 minutes, then the scheduled job will sleep for the entire 20 minutes, and any deferred transactions that enter the deferred transaction queue during that time are not pushed until 20 minutes have elapsed. Therefore, if you are using serial propagation, then consider setting delay_seconds to a value of 60 seconds or lower.
If you set a value of 20 minutes for parallel propagation, then the parallel push checks once a minute. If you can afford this resource lock, then the relatively high delay_seconds value of 20 minutes is probably most efficient in your environment. If, however, you cannot afford this resource lock, then consider setting the delay_seconds value to 10 or 20 seconds. Although you will need to execute the jobs more often than if the value was set to 1200 seconds, you still gain many of the benefits of the delay_seconds feature (versus the default value of 0 seconds).

JSP Page getting expired with in 2 or 3 minutes.

Hi Experts,
We have developed an j2ee application which runs on Oracle 9ias application server v 1.0.2.2. The operating system is IBM AIX so we are using IBM JDK 1.3.1. The problem we are facing is the session get's expired with in two three minutes. But the application server session time by default is set to 1200 seconds that is 20 mins. Initially we had a problem that the server often crashes writing some core dump. We could find a ultimate solution for this either from IBM or Oracle side.
Right now we r able to run the applciation by specifying the heap with Xmsize option. Does this heap size setting have any relation with session object.
How are session objects garbage collected. Is there a different algorithm for session object garbage collection.
Expecting timely help from the Experts as this is crucial for us.
Regards
Barath Kumar

The heap size shouldn't have anything to do with the expiration of the session. The only factors affecting session timeout should be the web.xml file (<session-timeout> tag under <session-config>) and any instances of session.setMaxInactiveInterval(int) in your code.
There is a question that you should resolve before going any further; is your session timing out or is the container losing it?
To test, create a class that implements HttpSessionListener and implement the sessionCreated and sessionDestroyed methods to give yourself a status message when the session is created and destroyed; a simple System.out.println will do the trick.
Add your new class to the web.xml with a listener tag:<listener>
<listener-class>somepkg.ListenerClass</listener-class>
</listener>The new class should bind to the session on creation and let you know when the creation and destruction events take place; if you get a status message when the session is created, and subsequently lose session information without a message when the session is destroyed, then the container has dropped your session and you need to complain to Oracle.
I've had exactly this problem; I believe there is a bug already filed, but I couldn't locate it quickly.

Can JSP be used to simulate Multi Document Interface?

I am new to JSP and I am trying to reimplement (migrate) a PowerBuilder based GUI application, with heavy use of "Multi Document Interface" (multi frames).
My questions are:
1- Does JSP supports "Multi Document Interface (MDI) like" functionality? Can anyone send me a simple JSP example where a click on a one JSP page causes multiple frames (pages) to appear in the same browser?
2- How one can implement Multi Documment Tabbed Interace? This is where JSP renders more than one page each with a tab. Clicking a tab brings its corresponding page.
Thanks again,
Devel1

JSP is loaded in a web-browser. Hence there is no MDI possibility. What you can do is for each click open a new window. Consider each window like a separate MDI form.
Otherwise you can generate an applet that uses Swing/awt and use the MDI capabilities in these technologies. Of course this is a much more cumbersome method than the previous one.

Servlet/JSP client timeout handling

Hi,
Is it possible to detect a client timeout in a servlet / jsp ?
Example,
I go to a page that is displayed by a servlet. I put Thread.sleep in the servlet to simulate the request processing time.
Assuming now I close the browser (or any other client) and the servlet tries to write the response, will it throw any exceptions ?
What can I do to check the client status before trying to write the response back ?
Thanks
Mandar

Hi,
The servlet did not throw any exception when I tried to write the response back after sleep.
Code is as shown below
try{
Thread.sleep(60000);
catch (InterruptedException ie){
logger.error("Someone interrupted my sleep",ie);
logger.info("End sleep for 1 minute");
try{
response.getOutputStream().write(2);
response.flushBuffer();
catch (IOException ioe){
logger.error("IOException occured",ioe);
throw ioe;
}

How can I stop the execution on a JSP page and start it again

Hi
I am making a program that simulates how to manage transactions when accessing a database by using locks. I have run into a problem and I hope someone has the time to help me.
When a user does an update the transaction commits and releases its locks when the program executes
<%stmt.executeUpdate("commit!"); %>
I need to put a break in to stop the program executing this statement, to illustrate the lock is set correctly.
I have tried to put in an alert box but this does not prevent the rest of the java code being executed.
I have tried to use prompt boxes, JavaScript functions, but these functions cannot have any java code in them.
I have tried using the java.swing JOptionPane boxes but this didn?t work either
I have tried to get input from the user but I don?t know how to retrieve this data on the same page. (As far as I know you have to use submit and even refresh the page or retrieve it on the next page).
Does anyone know how I can stop the execution on a JSP page and start it again (on same page)
Mette

I already have another client (Tomcat jsp application) running and it throws a SQLException correctly when I don�t put in a commit=true statement and don't close the database connection.
But the problem is how to get the code above to stop to illustrate I have set this lock.
I have tried to use the JOptionPane but because my program is running in a web browser I cannot use the JOptionPane dialog box.
I have tired using an alert box but it executes the commit statement before the alert box is dispayed. So this does not work
While (i < 2)
if( i==1)
%>alert(�The transactions commits when you press Ok�); <% //what it to stop execution here
else
stmt.executeUpdate(�commit�);
I am not using threads so I cannot use the sleep function.
I am using mysql and have already configured it to detect deadlocks and how long to wait for locks.
Thanks for your help
Mette

Menu in jsp page

Hello!
Here is the error I obtain while opening the jsp page where I added a menu as follow:
<h:selectOneMenu value="#{MyNewUserWizard.name}" style="width:150px" >
<f:selectItems value="#{MyNewUserWizard.names}" />
</h:selectOneMenu>
The error:
javax.portlet.PortletException: org.apache.jasper.JasperException: Value binding '#{MyNewUserWizard.names}'of UISelectItems with component-path {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /jsp/wizard/new-user/my_person-properties.jsp][Class: javax.faces.component.html.HtmlForm,Id: person-props][Class: javax.faces.component.html.HtmlSelectOneMenu,Id: handleMetaDataEvent_id25][Class: javax.faces.component.UISelectItems,Id: handleMetaDataEvent_id26]} does not reference an Object of type SelectItem, SelectItem[], Collection or Map but of type : null
Does somebody know what is this error?
Thanks.

I've done this very recently. In fact, tiles has very little to do with the menu itself.
In your layout, define where you want the menu to go.
<tiles:insert attribute="menu" />Now, in the actual file, create your menu structure. This part is up to you. I've used http://www.brainjar.com/ as a starting point for the client side actions.
On my menu page, I call a method on a custom object that returns the menu bar object. Currently, I'm working on putting this menu into some sort of cached object so it doesn't have to rebuild it on every page request.
Perhaps I've misread your post and you're looking to use tiles, in and of itself, to simulate menus? Otherwise, I hope my post helps.

Java code in jsp source files is not allowed in ojsp.next mode.

Hi,
I’m working on WC Spaces Customization library “com.acme.custom.webcenter.spaces.war”. From time to time, when I deploy the library to WC Server, it errors out.
weblogic.management.DeploymentException: Cannot undeploy library Extension-Name: com.acme.custom.webcenter.spaces, Specification-Version: 11.1.1, Implementation-Version: 11.1.1.2.113 from server WC_Spaces, because the following deployed applications reference it: webcenter-rest.war, spaces.war, sharepoint-servlet.war, webcenter-rss.war
If I try to login the Spaces, I get “Java code in jsp source files is not allowed in ojsp.next mode.” Should I stop the Spaces server before the deployment? In this case, other people won’t have accesses to Spaces? The deployment error doesn’t happen all the time.

I don't think that this error is based on ojsp.next mode. The first error I see is that the application can't be undeployed. After that you get the 'ava code in jsp source files is not allowed in ojsp.next mode.' error. As you said this only happens sometimes which also point to an other problem and not to the jsp error.
Have you ask this on the {forum:id=354} forum?
For me it's more a deployment/redeployment question.

JSP works in IE 7 and Opera 9.1 but not Firefox 2.0

Hi everyone,
I have a JSP with a form and a list box. When the user selects a value in the list box the form is submitted:
<form id="ampForm" method="POST" action="AMPSearch">
    <fieldset>
        <p>
            <label for="amp">
                Actual Medicinal Product Search Result:
            </label>
            //Here is where I think the problem lies the "onchange" method does not appear to be recognised by Firefox.
            <select size="10" name="amp" onchange="ampForm.submit()" class="listbox">
                <c:out escapeXml="false" value="${requestScope.ampList}" />
            </select>
            <input type="hidden" name="ampList" value="<c:out escapeXml="true" value="${requestScope.ampList}" />" />
               </p>
        <p>
            <label for="ampp">
                Actual Medicianl Product Pack Sizes:
            </label>
            <select size="10" name="ampp" class="listbox">
                <c:out escapeXml="false" value="${requestScope.amppList}" />
            </select>
        </p>
        <c:if test="${!empty requestScope.amppList}">
            <p>
                <label for="quantity">
                    Quantity:
                </label>
                <input type="text" name="quantity" value="" />
                <input type="submit" value="Add Order" name="addOrder" />
            </p>
        </c:if>
    </fieldset>
</form>This all works fine in IE7 and Opera 9.1 and Netscape 8.1 when it is set to display like IE, but not in Firefox 2.0 or when Netscape is set to display like Firefox.
Does Firefox not recognise the "onchange" method? What should I use instead? Any help would be much appreciated.
Tom

Not to worry people, I have done it again.
For some reason when I post on here a few minutes later I figure the problem out even though I have been struggling with it for ages.
The form should have had name="ampForm" not id="ampForm". Stupid thing.

OracleAS - NULL ProviderSession after 15 minutes (Using Oracle PDK Portlet)

We have recently deployed an oracle pdk portlet java application (developed in JDeveloper 10.1.2.1) to an OC4J on a server running OracleAS 10g (9.0.4).
We are currently facing issues where our ProviderSession becomes null after 15 minutes.
In our jsp's we implement the following:
PortletRenderRequest pReq = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
ProviderUser pUser = pReq.getUser();
ProviderSession pSession = pUser.getSession(false); In our provider.xml file within our JDeveloper project/portlet we have set the following tag: <session>true</session>. In the provider itself, under the User/Session Information section, we have selected the User option, set the Login Frequency to Once Per Session and checked the box labeled 'Require portal user specific session information'.
In our web.xml file within our JDeveloper project/portlet we have set the following tag: <session-config><session-timeout>35</session-timeout></session-config>
As long as we stay within our portlet we don't seem to lose our ProviderSession, but after 15 minutes, if we try to access the portal page (to switch the language on the page for instance) the ProviderSession is null. This operation always works when we are under this 15 minute limit.
We have tried to change opmn.xml (increasing OC4J start timeout from 900 seconds to 1200 seconds),
modplsql conf (PlsqlIdleSessionCleanupInterval, changed from 15 to 30 minutes) and we have also tried disabling the Global Inactivity Timeout variables, but no luck as of yet.
Any help would be much appreciated !
Thanks

HI
i am also facing same problem with session but in simple portlet with ajax implementation.
i am setting session in portlet jsp with following code using oracle application server portal 10g.
(here portlet jsp means which is included from portlet.)
session.setAttribute("map",map);(here session is implicit object )
i want to call ajax jsp from portlet jsp with below code.(i.e setting session in portlet jsp and accessing in ajax jsp)
var url = "<%=renderRequest.getContextPath()%>/AjaxProcessRequest.jsp?q=" + random;
var pars = '&namespace=<portlet:namespace/>' +'&imagesPath=' + '<%=imagesPath%>';
var myAjax = new Ajax.Updater(
{success: 'emailbody'},
url,
method: 'get',
parameters: pars,
onFailure: reportError,
evalScripts: true
i am accessing map object from session in my AjaxProcessRequest.jsp as shown in below code.
Map map=(Map)session.getAttribute("map"); (here session is implicit object )
here map object is getting null from session.
Please help on this if u know about this session.
Regards
Raju

Client reconnection to conventional cluster taking about 9 minutes

Hi,
I've set up a 3 node OpenMq (4.4) conventional cluster and am having trouble with client reconnections when I simulate a halt on a node.
I have two threads within the same process, sending to a pre-configured destination and replying using a temporary queue. Each have a JMS connection to the same home broker. If I bring the home broker down with either the imqcmd command or with a ctrl+c, the goodbye messages are sent and the client connections are immediately reestablished by the connection factory with the next broker. But... if I remove the broker from the cluster by simulating a BSOD, power failure, etc, no goodbye messages are sent (obviously) and the connected clients are left 'connected' to the dead broker and only reconnect to another broker after about 9 minutes.
I read in the docs that the 'imqPingInterval' property can be used to test the client connections but it doesn't seem to be doing the trick. After I've cut the power to the broker's virtual machine, I'm seeing the ping messages in the logs, e.g.:
FINEST: Outbound Packet:PING(54):296-127.0.1.1(bd:ea:13:9b:ae:a)-51155-1267024410861;BrokerAddress=10.59.148.9:7676(1082), ConnectionID=4090718717872600064, ReconnectEnabled: true, IsConnectedToHABroker: falseAt this point, telnet cannot connect to 10.59.148.9:7676 so it's definitely gone.
Finally after about 9 minutes, the following shows up in the logs:
24-Feb-2010 15:26:26 com.sun.messaging.jmq.jmsclient.ExceptionHandler throwJMSException

Handling a machine failure seems like a pretty standard scenario for a cluster so I'm sure there's something I've mis-configured.
Is there something I can do to fix this?
If not, the only other alternatives I see are to either:
1) Try the HA custer. But I'm not sure this will fix the problem if the client is waiting on a dead socket.
2) Lower the message ack to something like 10 seconds and reconnect to the cluster for a retry every time we get a JMSException. But this is obviously not ideal either.
Any suggestions would be great.
Thanks,
Nick

Hi Nigel,
The producer is configured to send messages every 5 seconds and the consumer is sitting with a message listener on the queue.
The producer send is failing each time with the following trace...

Using a real file path to include a JSP using RequestDispatcher

Hi,
I am trying to figure out how to use RequestDispatcher inside a servlet to include a jsp page using a real file path instead of a context path. So for example I would want to do something like...
RequestDispatcher rd = this.getServletContext().getRequestDispatcher("c:/tomcat/conf/think.jsp");
Is this possible? tomcat is complaining that the path does not start with a "/"
From a higher level I am trying to setup a solution where all of my web applications can share a set of global jsp pages and other resources. I know the easiest solution would be to put everything into one web application but this does not make sense in my situation because I have differnet web applications for different companies on the same server. Any help would be greatly appreciated. - krebsnet

First of all...
My test environment is Tomcat 4.1.24 and it runs on port 80 as my webserver as well.
I can place the .jsp (or .html) in the shared folder. Not in the lib or class folders but right in the shared folder. I can then call it from multiple contexts without using the context path. Just tested it a minute ago. For example I have test.jsp in the shared folder and loaded it from two separate contexts (one named /demo and one named /inetapps) by calling Load test. It loaded in both of them and neither contain a test.jsp file.

Connection pooling in a JSP

I hava an application that uses both a servlet and a JSP and I need to use connection pooling. I have a connectionPool class that works fine in the servlet. I create the pool in my init() method and access it when needed in doGet(). I would like to do the same thing in my JSP, but since the server creates the servlet code, how can I create the connectionPool only once rather than every time the JSP is invoked? In other words, what can I do to simulate a servlet's init() method in a JSP?

If you read the JavaServer Pages specification, you will realize that there is provision for such things.
The following is an extract from the JavaServer Pages specification 1.1...
The contract also describes how a JSP author can indicate that some actions must be taken
when the init() and destroy() methods of the page implementation occur. In JSP 1.1 this is
done by defining methods with name jspInit() and jspDestroy() in a declaration scripting
element in the JSP page. Before the first time a request is delivered to a JSP page a jspInit()
method, if present, will be called to prepare the page. Similarly, a JSP container can reclaim
the resources used by a JSP page at any time that a request is not being serviced by the JSP
page by invoking first its jspDestroy() method, if present.
So, you should dfine a method with the signature public void jspInit() in your JSP and do the one time initialization therein. Also, you do the associated cleanup in a method with the signature public void jspDestroy()

Implementing session timeout in JSP - - Urgent help !

Hi
I have a requirement where I need to write a session timeout functionality in a JSP such that the page is redirected to a different page if there is no activity for 5 min.
I tried the following :
1.On the onload of my JSP, i created a new session from the current request using the following code snippet :
          HttpSession pSession = request.getSession(true);
          pSession.setAttribute("loggedin","true");
          pSession.setMaxInactiveInterval(10);
2. Then on any action performed on the JSP, i called the collowing JS function before invoking the server side code.
/** function to check the user session **/
function fnChkSession()
     alert('Inside check session');
     <%
          try
               System.out.println("The value of the session var loggedin : "+pSession.getAttribute("loggedin").toString());
               System.out.println(" getMaxInactiveInterval() value is : "+pSession.getMaxInactiveInterval());
          catch (Exception e)
               System.out.println("** Inside the fnChkSession exception catch block **");
          if (pSession.getValue("loggedin") == null)
     %>
          alert('Session has expired');
          document.forms[0].submit();
     <% } %>
But when I execute this code ,even after 10 secs my session seems to be alive.I can retrieve the session attribute after 10s.
I also tried setting the session-timeout value in the web.xml. It didnt work.
Can anyone pls help me on how to proceed further on this.
Thanks

You are confusing java with javascript.
These two things are not the same.
The lifecycle goes something like this
1 - Request is made to server
2 - Java/JSP runs java code, produces HTML page
3 - java stops running
4 - html is sent to browser, and javascript starts running.
You cannot call java code from browser events (such as onload, onclick, onchange...) The only way to run java code again is to submit a request (normally by submitting a form, or clicking a link. )
If you want a javascript solution, in IE, use the window.setTimeout() method to execute some javascript code after a certain period of time.
A more generic approach would be to use the refresh header. Set the timeout for the refresh header to be 300 seconds. If the user stays on the same page for more than 5 minutes, it will redirect to the new page.
Hope this helps,
