GetMaxInactiveInterval() I

I get following error while running my servlets can any body tell about it
java.lang.NoSuchMethodError: javax.servlet.http.HttpSession: method getMaxInactiveInterval()I not found
How to remove this error?

Hi,
Is there a typing mistake in your getMaxInactiveInterval()I method call ? Remove the last character 'l'.
cheers.

HttpSession::getMaxInactiveInterval method not found

Hi,
I am trying to run a servlet on iPlanet Web Server 4.1 SP7.
The servlet uses the getSession methods to access the session data. However, when I make the getSession call, an exception is thrown from NSHttpServletRequest indicating that the method HttpSession::getMaxInactiveInterval() cannot be found.
(See below for stack trace.)
Has anyone come across anything similar?
Thank-you,
Mike

Session time out problem

Hi guys
I am using WSAD 5.0. the problem that i am having is that i have a properties file where i give the session time out value along with many other things. and when a user logs in a servlet takes those values from the properties file and sets the session time out value, using session.setMaxInactiveInterval(). but the problem is the session is still maintained even after the stipulated inactive time. Can any one tell me what could be the problem.
Note: when i say session.getMaxInactiveInterval(), i get the value that i have set in the properties file.
Thanks

You're sure you specified seconds rather than milliseconds?

Session Time Out and Redirect to login page - urgent

My problem is I want to display alert message and redirect to the home page when session expires.
Iam using TimeOutListener in my application as follows.
public PhaseId getPhaseId() {
return PhaseId.ANY_PHASE;
public void beforePhase(PhaseEvent phaseEvent) {
     FacesContext facesContext = phaseEvent.getFacesContext();
HttpSession sessionx = (HttpSession)facesContext.getExternalContext().getSession(false);
if(sessionx == null) {
     FacesUtils.sessionCheck = true;
String ampee = (String)((HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest()).getAttribute("ampee");
if(ampee != null && ampee.equals("ampee")) FacesUtils.sessionCheck = false;
if(phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE) {
     if(FacesUtils.sessionCheck){
     facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, "", "sessionExpired" );
     FacesUtils.sessionCheck = false;
ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
          HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();
          HttpSession session = request.getSession();
          if (session.isNew()) {
               try {
               String errorPageURL = externalContext.getRequestContextPath() +
               "/index.jsf?errorpage=true";
               externalContext.redirect(errorPageURL);
               }catch(Exception e){
                    e.printStackTrace();
here i have appended param errorPage=true...
in jsp page i have used following code to get the param<% if(request.getParameter(errorPage)!=null && request.getParameter(errorPage).equals("true")){%>
<script>alert("session expired");</script>
<%
%>
Can any one help me how to Implement this?
Do u know another way pls let me know...

Consider using the Javascript setTimeout() function in conjunction with HttpSession#getMaxInactiveInterval(). The HttpSession#getMaxInactiveInterval() returns the remaining seconds of the session lifetime.
Basic example:<script>
    setTimeout("alert('The session will timeout after one minute.')", <%= (session.getMaxInactiveInterval() * 1000) - 60000 %>);
</script>I've given the client one minute (60000ms) extra time space to respond accordingly.
Use this in combination with the following head:
<meta http-equiv="refresh" content="<%= session.getMaxInactiveInterval() %>;url=login.jsf">which will redirect to login.jsf if the session is timed out. You can also redirect to another page of your taste, e.g. error.jsf or so.

Session scope and request scope

Hi,
I've a manage bean in session scope and within this bean I've a reference of another
object (class person) . My question is, do i have to register this class in my faces-config-xml and if yes which scope should it have? session or request?
Or it isn't necessary to register it?
thanks

helllo,
can someone tell me what the line in the preceding coed means?

How to stop a pop up window if the session expires

Hi
I have a situation wherein i have my jsp page. in that i have a button on clicking it a pop up window will open to take a input parameter.
Now what we want is that if the session is not valid than the pop up shud not open.
Currrently what is happening wen the session is not valid the popup gets open and in that popup a login page is coming.
The logic for pop has been put in a javascript code which gets executed when the page was first loaded . So even if i put a logic for checking the session before the popup opens it wont work. So what can be a possible way i can do it?
I am writing a scriptlet to check the logic for valid session.
function changeLimitFunc(count)
     <% if ((request.getSession(false)== null)) {%>
          return false;
     <%}
     else {%>
popUp('');
          openedForm.target = 'change_download_limit';
          openedForm.submit();
<%}%>
and in the page which geot loaded the same code appears like
function changeLimitFunc(count)
     popUp('');
               openedForm.target = 'change_download_limit';
               openedForm.submit();
this popUp is amethod where we are createing our popup.
please help me out to resolve it

I have written this javascript code to block the popup
function changeLimitFuncUnopened()
if (checkIfValidSession()) {
          popUp('');
          unopenedForm.target = 'change_download_limit';
          unopenedForm.submit();
          else {
          return false;
function checkIfValidSession() {
<% HttpSession httpSession = request.getSession(); %>
var lastAccessTime = <%= httpSession.getLastAccessedTime() %> ;
var maxInactiveTime = <%= httpSession.getMaxInactiveInterval() %> ;
var date = new Date();
var time = date.getTime();
if( (maxInactiveTime > 0) && ((time - lastAccessTime) > (maxInactiveTime * 1000))) {
     alert("Session TimedOut. Please Re-login!!!");
     return false;
else {
     alert("inside else true shud go");
     return true;
The code is working fine and blocking the popup. But I am not sure if this will be a correct fix.

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,

PROBLEM USING FILTER TO KNOW SESSION EXPIRATION

Hi, i'm using a filter to know when the session expires but it appeasr not to work, so i am a bit confuse because the filter always executes well but when the session gets the timeout and the user send a request it isnt executed, the server redirects the user to the login page.
I am not sure about it, but is it possible that the reason of why the filter is not executed, is becuase i am using the apache form-authentication????
filter's code:
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest req;
RequestDispatcher disp;
HttpServletResponse res;
boolean userInSession;
String forward = getConfig().getInitParameter("sessionClosed");
req = (HttpServletRequest) request;
res = (HttpServletResponse) response;
System.out.println("InFilter");
userInSession = req.getUserPrincipal() != null;
if(userInSession) {
chain.doFilter(request, response);
System.out.println("Session: " + req.getSession(false).getId());
System.out.println("Session: " + req.getSession(false).getMaxInactiveInterval());
System.out.println("getSessionTime: " + req.getSession(false).getCreationTime());
} else {
disp = req.getRequestDispatcher(forward);
disp.forward(request, response);
res.sendRedirect("http://www.google.com");
System.out.println("outFilter");

I haven't used it because it is deprecated but I think it does what

How to invalidate session in absence of activity

hello ppl
i hav a prob...i want to invalidate my session if no activity happens on my screen for a specified period...how do i
chk the time and also how do i track my activity....
i also need to display a prompt to the user informing of the time expiry and need a response from him

i also need to display a prompt to the user informing of the time expiry and need a response from himHTTP disallows push, so forget about it. Best what you can do is to use Javascript's setTimeout() function in combination with HttpSession#getMaxInactiveInterval(). This way you can use Javascript to show some message in the page when the session is timed out.I'm afraid that wass what was explained under the URL(Earlier Post) which was what metioned in my earlier reply.
Why are repeating the same solution out here ??

How to send a Keepalive from a solaris machine???

Hi,
Do we have any Java API or way to send a Keep Alive from a client before the server sends a RST.
I have done the following kernel level settings in the Solaris box -:
ndd -set /dev/tcp tcp_keepalive_interval 14000
The reason we wanted to use keep alive was because we are seeing increasing number of IDLE connection in the Solaris box which is resulting in "too many open files error" and degrading the performance of the application.
netstat -an | grep IDLE | wc -l
65000
Do we have any other way to flush these IDLE connections?

In your servlet that controls the AJAX requests, set the session's timeout interval to 2 minutes less than its current interval. That way, the timeout gets shorter every 2 minutes with every AJAX call (which occurs every 2 minutes). In your servlet that controls your non AJAX requests, set the session's timeout to 1 hour.
//In the AJAX controlling servlet:
int twoMinutes = 2 * 60;
int inactiveInterval = session.getMaxInactiveInterval() - twoMinutes;
session.setMaxInactiveInterval(inactiveInterval);
//in the normal request controlling servlet:
int oneHour = 60 * 60;
session.setMaxInactiveInterval(oneHour);
Another way around it would be to store current request time in the session. For your AJAX requests, compare the current request time with the last request time and subtract that from the MaxInactiveInterval, which would give you more accuracy and less cross-dependence on the interval of your AJAX requests.
Ok,
I got the answer by this way...
Thanks to ALL.

InfoView Timeout Crystal Report Server 2008 Business Objects 3.1

After two days of digging, poking, prodding and fumbling around in the dark I finally found a method (one that actually works!) to change the timeout period for InfoView. Venkat Patnaik (second message) posted an excellent procedure in a place that is not readily apparent:
/message/8250448#8250448 [original link is broken]
Following his method, my InfoView seems to timeout after about 3 minutes. I am going to play with the settings to see if I can get it dialed in a bit more, but I wanted to post this so there is a thread with a relevant subject so people can find Venkat's excellent post. Thanks Venkat!

Wow I am getting really tired of SAP's constant broken links and moving things around. That link worked great a couple of weeks ago when I posted this message. I did some digging around for that particular thread but I was not able to find it this morning. Maybe it was deleted....
Luckily I documented my procedure for making these changes and I did not stray from Ventak's original procedure except for making paths and such specific to my environment.
Basically the timeout values need to be changed in several places:
1. Stop the TomCat server via the Central Configuration Manager before doing anything else.
2. Modify the web.xml file in each of the following directories:
C:\Program Files\Business Objects\Tomcat55\webapps\InfoViewApp\WEB-INF\web.xml
C:\Program Files\Business Objects\Tomcat55\webapps\InfoViewAppActions\WEB-INF\web.xml
C:\Program Files\Business Objects\Tomcat55\webapps\CmcApp\WEB-INF\web.xml
C:\Program Files\Business Objects\Tomcat55\webapps\CmcAppActions\WEB-INF\web.xml
Parameters to change:
***This parameter may not exist in all web.xml files.***

    <context-param>
        <param-name>logontoken.enabled</param-name>
        <param-value>true</param-value> (Change to false)
    </context-param>

    <session-config>
        
        <session-timeout>20</session-timeout>   (Change to 5)
    </session-config>
3. Modify the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 12.0\CMS\Instances\<SERVER NAME> u2013 IdleSessionTimeout=0x927C0 (600000)
The key is a REG_DWORD value and the value is in hexadecimal. Set the timeout value to 90,000 ms u2013 1.5 minutes with the value 0x15F90. You can use other hex values as desired, 90,000 ms worked for me.
4. Restart the TomCat server.
5. Add the following command line parameter to the CrystalManagementServer parameters in the server properties window of the Central Management Console <-failovertimeout 1.5>
6. Restart the CrystalManagementServer via the CMC
Good luck, let me know if you have any questions.

Send message to client before session invalidated

i am using jsp and java servlet tech. for my web application.
my problem is :
i want to send a message to client before session invalidated.
please help me to find the best way to solve my problem.

You can detect session termination by putting an object in the session attributes which implements HttpSessionBindingListener. What you can't do is send a message to a client, basically because all http transactions are initiated by the client. The only way I can see you could do this is to put an applet on your web pages which periodically consults the server concerning the session state.
Then the problem is that there's no obvious way of determining if the session is about to timeout, only whether it has or not. Your applet couldn't return the session cookie (as such) because that would reset the session timeout and the session would never expire. If you could obtain the session without reseting the expiry (perhaps from SessionContext though that's depracated) you could look at getLastAccessedTime() and getMaxInactiveInterval, but I don't know that this can be done. You can't even count, on some systems, on the session remaining in memory.
If you really need to do this you may need to consider implementing sessions for yourself. I've done this for non-webapp based logins and it's not too hard.
