I am using session.invalidate() to clear session and

sendRedirect to login page but .. when i am click back button again it going my home page....
how to avoid this problem....

The browser stores the page in the cache and renders the cached page when you press the back button. You can use headers to stop the browser from caching the pages that you don't want to be cached. Like in your example you can apply the headers to the home page. Look here for more info...

How to use session and cookies in struts

I have login page. If user enters his username and password go to other page. then i copy this url and put the address bar automatically go to this page without enter username and password. So this time i want to send one message "Your session is expired". How can i tell this message page in struts. Please tell me.

I don't want to sound like a jerk (but I often do), but wouldn't it be easier to look for a good struts manual to look this stuff up in?
If each time you don't know something you ask people in this forum to explain it to you then you'll be developing for a LONG time. If you do find a good manual (hint: a book might help a lot), then your lack of struts knowledge isn't really a problem anymore.

Can you use Crystal Reports on a webpage without having to use session?

In all of the examples I have seen it shows using the session to store the reportdocument object between postbacks. That means that clicking the page buttons fires a postback. Other reporting tools such as PDF, ActiveReports, and others do not have to do this. Is this a limitation of Crystal and a COM backend or is it just a common sample and not the only option?
How do you get paging to work without having to use session and do postbacks? AJAX, Javascript, converting to a PDF, etc. would all be possible ways to not require a postback.
My problem is that I am using SQL Server to store the session and the reportdocument object is not serializeable. I have been told I can buy Crystal Report Server for $5000 and this will work. But in reality I can buy other reporting tool for $500 or convert them to SQL Reporting and it will work as well. So I am trying to be reasonable and figure out what I need to do. That seems like a bit much to need a whole server application to serve the reports just to turn on paging for a couple of simple reports. I'm hoping there is a way to not use session to get paging to work.
I have consider pushing the report into viewstate and not session. But I would rather not push it into either. Is this a valid option?
What is the typical way to handle this sort of thing? Do you really have to push it into session to get the CrystalReportViewer control to page on an ASPX page. What other options are there?
Any suggestions, thoughts, or ideas would be very much appreciated. This is causing enough of a problem where the company is asking me to look at alternatives if we cannot solve this.
Best regards,
Jon

Acrobat doesnu2019t cause postbacks when paging because the acrobat reader installed locally, so its viewing is in a client-side control. I imagine the same thing is the case for ActiveReports (some sort of client-side activex control installed).
If the winform viewer was used on in your web page, then you wouldnu2019t get postbacks either, but then you'd need Crystal Reports runtime on the client to view in that control. And placing a winviewer in a web page give me shivers...
So, to avoid using session, recreate the reportdocument and re-load the report on postbacks.
As Surabh mentioned, you can serialize the report but you will have to use teh InProc RAS. There is an issue thought; you start to get load errors and otehr errors after viewing 3 reports. I belive this has been reported to R&D for a fix comment, but I do not have and ETA at this time. The code for the InProc RAS SDK would be as follows:
           If Not IsPostBack Then
            Dim rpt As New CrystalDecisions.CrystalReports.Engine.ReportDocument
            Dim boReportClientDocument As CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument
            '           rpt.ReportAppServer = "Inproc:multithreaded"
            rpt.Load("c:inetpubwwwroot     estSerializeInprocRASEmployee Profile.rpt",
           OpenReportMethod.OpenReportByTempCopy)
            boReportClientDocument = rpt.ReportClientDocument
            Dim x As String = boReportClientDocument.DataDefController.Database.Tables(0).Name
            '     boReportClientDocument.DatabaseController.logon("sa", "admin")
            Dim convertUtil As New CrystalDecisions.ReportAppServer.Utilities.Conversion()
            Dim serializedDoc As String
            serializedDoc = convertUtil.ToString(rpt.ReportClientDocument)
            Session.Add("SerializedDoc", serializedDoc)
            'ViewState.Add("SerializedDoc", serializedDoc)
            Response.Write("The document has been serialized.")
            CrystalReportViewer1.ReportSource = boReportClientDocument.ReportSource
        Else
            Label1.Visible = False
            Button1.Visible = False
            Dim x As String
            x = ViewState("SerializedDoc").ToString()
            Dim deSerializedDoc As ISCDReportClientDocument
            Dim convertUtil As New Conversion
            deSerializedDoc = convertUtil.ToReportClientDocument(Session("SerializedDoc").ToString())
            'deSerializedDoc = convertUtil.ToReportClientDocument(ViewState("SerializedDoc").ToString())
            CrystalReportViewer1.ReportSource = deSerializedDoc
            Response.Write("You are viewing a de-Serialized report" & "<BR>")
            Response.Write(ViewState("SerializedDoc").ToString())

How the page should redirect when we click a link using sessions

Hi Friends,
I have two links namely Gujarati and English in the page. before logon to the application, when i click the Gujarati link, the total content of the page should change to Gujarati and for english as same..How to do this using sessions and Internationalization(i18n).
It can be easy if anybody is using Property files and resourcebundle.
Thank you..

I will give u a very simple example of using session here.
Lets say you have 2 links in your HTML or JSP page: Gujarati | English
In you nextPage.jsp, you need to do the following:
<%@ page session="true" %>
By using page directive with session attribute to true will make HTTPSession implicit object available with you in your JSP.
Now you can save your request parameter lang to this session for further identification of user's selection for the language.
This is how it can be add user selected language into sessions in JSP:
<%
session.setAttribute("Language", request.getParameter("lang"));
%>
To retrieve this value for further usage, you can use the following:
<%
String lang = (String)session.getAttribute("Language");
%>
If you are using servlet instead of JSP, you can handle the same by having following lines of code in your servlet:
To set a value or object in the session:
HttpSession session = request.getSession();
request.setAttribute("Language", request.getParameter("lang"));
to retrieve a value or object from the session:
HttpSession session = request.getSession();
String language = (String)request.getAttribute("Language");
I hope this helps to solve your problem for having selected language using sessions. Once you know which language the user has selected you can use internationalization to convert your pages to other languages.

Examples with JBeans / Session and Entity

I wish if you could give links to web pages were to download examples of Java Beans
using Session and Entity. In whole, JB that access relational databases.
Best, would be an example to test and also that include the source code. Maybe
an open source.
Thanks for your directions,

Thanks for your fast answering!
Another thing: if I plan to use this way of developing my applications, could be a good idea putting my Session EJB with my business methods in session, instead of calling a new EJB and removing it each time I load a servlet?
Thanks again.That depends on what you need to do. If you need to retain state between business method invocations (like a shopping cart) then store a Stateful Session bean in your http session. If you do not need to retain state then simply lookup a Stateless session bean each time you need it.

Urgent!! Problem in using session invalidate()

Dear all,
I think may be the problem has been posted here before, but i can't find the solution yet. I hope you can help me about this.
My case is that i wrote a logout servlet for my web site. So i use session.invalidate() in the servlet. After that it will redirect to the home page again. At this time, NullPointerException is thrown. I have tried many ways to solve this problem, but still failed.
Can anyone help me? Thanks for advanced.

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this?

First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

How to use session in webservice?

In C#, can use session variable in a webservice object.
How to use session in Java webservice?
Who can give me a example?
Thanks a lot

Did I use session in a wrong way?No, you are using the session correctly. The code looks fine.
Check
- your spelling of the attribute names - obviously they must match
- the ids of the sessions you get both times: session.getId(). If they have different ids, then most probably the session is being lost somewhere.
There are a number of reasons to lose a session. If you close the browser, invalidate the session in code, or lose the cookie recording the id. This happens when you change from https to http, so a session can be lost that way.
The session is normally maintained by session cookies. If you close your browser you lose the cookie. If you have disabled cookies on your machine then it also might not work.
In cases such as that you should be using the method response.encodeURL() to maintain the session for you in any hyperlinks you produce. Struts normally handles that for you though if necessary.
Hope this helps,

How to use session in Struts

Hello, there:
It's a simple question.
I have a web app which has a login page, in its action class I create an object, user, and save it into session by using request.getSession(true).setAttribute("user", user).
In another action class, I want to use the info of user then I use request.getSession(true).getAttribute("user"); however, the returned object is NULL. Did I use session in a wrong way?
Thanks,
Sway

Problem in using XSQL-session and connecting database

Hello
Let me explain clearly. We have some data entry screens for which we want to use session with time out option. Normally in Servlet, we use to create a session with max age option. Then everytime the browser call the servlet we use to check for session.isnew(). If it is new session then we will forward the page to Relogin (because session is timed out) or we proced with further action.
In XSQLServlet, how will do this. Do I have to create my own servlet extended from XSQLServlet ? Override the Service method and write about the session part and call
super(). Here only I am getting confused. In servlet mapping we have given for every .XSQL call run the XSQLServlet. How will I override this ?
And also we have problem with user id and password. We don't want to use the same id (system id as defined in XSQLConfig.xml) for every database connection. We want to define only the connection information like SID, Server, Port number. But user id and password should be dynamic. How can I achieve this ?
Please help us on solving these problem. Thanks.
Lakshmi

You'll need to implement your own classes that implement the:
oracle.xml.xsql.XSQLConnectionManagerFactory
and
oracle.xml.xsql.XSQLConnectionManager
to change the way XSQL handles connections. Using this mechanism, you should be able to implement any alternative connection scheme you choose.
If you run into problems implementing these interfaces, give us a shout here in the forum.

How to use session state protection

I use Apex 3.2.1
I access my site by a url passing a parameter like this : f?p=101:1:0::::ITEM1:1234567. There is no login and password to access the site.
The value of the parameter ITEM1 is the authorization of the first page, with a database function for the verification.
To secure my site I want to use session state protection so, I enabled it , then I defined "Arguments Must have checksum" for the page 1.
Now , when i try to acces my site with the same url it does not work.
it is the first time a try to use session state protection, could someone tell me what's wrong?

Hi user5719906,
I would suggest that as you need to pass an item and are unable to generate a checksum as you are not yet logged in, that you will need to allow arguments without checksum for this page.
This could be a bit of a hole in your security, but as long as you know it is there and clear the cache for all pages that you branch to, you should be able work around it.
The issue is that a malicious user can set page and application items via the url to an unsecured page.
Regards
Michael

Please help me-it's urgent,maintaining session and security using cookies.

hi folks,
i presently developing a web site for an engineering colleege ,i am facing prob in maintaining the session using cookies,and destroying a cookie and keeping security to the user,There are four links on my webpage ,including a logout link,when i click the other links other than the logout,it works perfectly,and when i click the logout link,i am not able to disable the cookie and still able to visit previous pages by clicking the back button.please give a suggestion as such to disable the cokie and maintain the security for my web site.
Thank u....

Try out this login if it helps you.
Create a bean that stores some String value. Then make a object of this bean using the useBean tag with session scope when a user logs in. Store the name of the user in the bean and also set the same name value in the Session object. Then on every JSP page compare the value set in the session object with the bean variable (which will be having a session scope). If the value match, then the JSP page output must be displayed to the user. Then on the logout link, invalidate the session object using the invalidate() method of the session class. As a result now when you will try to navigate back to the old JSP page, null will be returned to you when you will try to retrive the name value from the session object. And since this null will not match with the value in the bean, you should not proceed further with generating the output. Hope this help

Using session variables

I use this session variable in an application.
<CFSET Session.CPActive = True>
I thought that the variable would be deleted when I close the
browser.
When I open a new browser window the Session.CPActive is
still defined and True!!??
Any comments on this?

Found the answer herre
http://livedocs.macromedia.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/common/html/wwhelp.htm ?context=ColdFusion_Documentation&file=00001156.htm
What is a session?
A session refers to all the connections that a single client
might make to a server in the course of viewing any pages
associated with a given application. Sessions are specific to both
the individual user and the application. As a result, every user of
an application has a separate session and has access to a separate
set of session variables.
This logical view of a session begins with the first
connection to an application by a client and ends after that
client's last connection. However, because of the stateless nature
of the web, it is not always possible to define a precise point at
which a session ends. A session should end when the user finishes
using an application. In most cases, however, a web application has
no way of knowing if a user has finished or is just lingering over
a page.
Therefore, sessions always terminate after a time-out period
of inactivity. If the user does not access a page of the
application within this time-out period, ColdFusion interprets this
as the end of the session and clears any variables associated with
that session.
The default time-out for session variables is 20 minutes. You
can change the default time-out on the Memory Variables page in the
Server Settings area in the ColdFusion MX Administrator.
You can also set the time-out period for session variables
inside a specific application (thereby overruling the Administrator
default setting) by setting the Application.cfc This.sessionTimeout
variable or by using the cfapplication tag sessionTimeout
attribute. However, you cannot set a time-out value for that is
greater than the maximum session time-out value set on the
Administrator Memory Variables page.
For detailed information on ending sessions and deleting
session variables, see Ending a session.
