Closing/ending a session in jsp

Hi guys i need help ending my session. I am using session just for parameter passing, my webpages doesnt need login logout function.
These are my basic code:
page1.jsp
<%
String prodlinesel = request.getParameter("prod_line");
session.setAttribute( "sessprodline", prodlinesel );
%>
page2.jsp
<%= session.getAttribute("sessprodline") %>
how,when &where do i end my session ? thanks so much

You can use session.removeAttribute("sessprodline");
Calling session.invalidate() will invalidate the session.
Otherwise it disappears after it times out - normally after about 30 minutes of inactivity from that session.

Session in JSP

Hi all,
I used session in my JSP pages. Now when user click Logoff link the page goes to a JSP page and there i invoked
session.invalidate();to end the session.
On that page there is a link to login again.
If the user use that and then login with a different ID and store some info in database it still shows previous users ID meaning that session is still getting old value although i invalidated it.
Can anyone please help me.

Hi CodeYoda,
Thanks for reply. I tried your code but still it doesn't work.
Now let me explain the situation, When i turned the machine this morning and started tomcat and run my application with a different ID, and i did some updates in database and it still shows the ID that i used when i created the session couple of weeks back.
Now i think this is a serious matter because it remembrs that ID only.
Now let me clear the concept again. my jsp pages are not linked by data transfer but they have links of all pages on the menu in every page so when they login and in the second page i stored the login name in session after that i used it in a page which has no connection with any other pages. Now what i did is i made the page available for session and then i used the login name.
Now is that mean that the login name is stored in that pageforever and since it doesn't send anything to logoff page and when we kill the session inlogoff page it is only killed in logoff page. That's my assumption. Can you please confirm me.
Thanks

...I'm using a separate DHCP on LAN. DTU & TSE (W2K8) are working 95% of time and sometime and randomly, one DTU has a full black screen. The only way to get the login screen of win 2K8 is to reset his own session.
Help will be really appreciated.

I have the same issue . . .
1. Sun Ray 5 (Sun Ray 4.2)
2. SRWC 2.2
3. Solaris 10 u9 X86 on two x2200
4. Terminal Server on Win2K3 R2 Standard x64 Edition SP2
I have a handful of users and they all logon the same way, which is to enter username & password then I have the following lines at the end of the users' individual .dtprofile file . . .
<begin snip>
DTSOURCEPROFILE=true
/opt/SUNWuttsc/bin/uttsc -b -m -O -u uname 192.168.100.29
exit
<end snip>
Of course 'uname' is actually the user name followed by the Terminal Server IP address and as you can see I am using the '-O' option, but every morning all the users on a server have their Sun Ray sessions reset and I find this in the messages file . . .
Mar 16 09:38:31 sunraya Sun Ray Connector proxy:[12941]: [ID 855542 user.error] Child closed socket prematurely, session shutdown
. . . . Using cron, I reset the Sun Ray service twice a day on both servers at 7AM and 7PM . . .
# cat /sunray-restart.script
# This is to restart SunRay 5 service due to
# what I think may be a memory leak that disconnects
# the SunRay Windows Connector every day

Handling Session in jsp and bean scope

i have problems with handling session in jsp
I want to check on all jsp pages
first thing is session is null
i want to him to be redirected to first page
and he should not be able to go ahead
I tried
if(session ==null)
response.sendRedirect("Login.jsp");
but this does not seem to work
It is very crtical problem can any one answer
this asap
Also i wanted to know that
I have bean which in turn calls static methods of another class which holds all DomainTable(database tables which do not change frequently)
Information .
This is bean is being implemented by me
in seession scope in a jsp
Do u guys think it would be goo idea to change
scop of this bean as Application in jsp
if so what would be advantages for same
I would appericate if i could a quick reply on both
question
as i am time crunch
arsh

You will always get some value of session and your code wont work. At the end of your Login.jsp, you should create a sesssion and store attributes. Check for these attributes in session, rather than checking session==null.

Handling End of Sessions

Hello,
          I want to handle end of a session. I want to redirect the user to the Login
          page when the session ends.
          What is the best way to do it? Is there an event that is generated when the
          session ends? If so how will my Servlet get that Event?
          I am using a combination of Html, Servlets, and JSP (transparently compiled
          to Servlets).
          Thanks in advance

          You cannot find when the WLS ends your session unless & until you write
          your own version of Event class.
          HttpSessionBindingListener is a best bet to implement this feature.
          (Causes an object to be notified when it is bound to or unbound from a
          session. The object is
          notified by an HttpSessionBindingEvent object)
          1. Create a class say NotifySessionTimeout that implements
          javax.servlet.http.HttpSessionBindingListener
          2. create an object of the above class and attach it to user session
          3. when the session is removed NotifySessionTimeout.valueUnbound( ) will
          be called by the servlet engine.
          4. you can implement valueUnbound( ) to do whatever you want.

How to Handle user Session in JSP

How to handle user session in JSP.......

tell me some Debugging tech. so i can overcome from my problem.....Do you use an IDE? Any IDE ships with a decent debugger where in you can just execute the code step by step, explore the current variable values and check what exactly is happening. For example Eclipse or IntelliJ. If you don´t use an IDE, then just place some System.out.println() or Logger.debug() statements at strategic locations printing the variables of relevance so that you can track in logs what exactly is happening.
or tell any other way to find is my page is thread safe or not...Just write correct code and narrow the scope of the variables as much as possible. If you for example assigned the user object to a static variable or as a servlet´s instance variable, then exactly the same user object would be used everywhere in the application. That kind of logical things.

How to end user session correctly as sys or system user

Hi,
Database version Oracle 10.2.0.3
We have to end user sessions to update database content. We cant stop/shutdown the instance but we have to assure that some users are not logged on.
So we are looking for a solution to end some arbitrary user sessions as sys or system user without using the KILL USER SESSION option. We want to assure that the user sessions end correctly.
Is there a possibility or a command in Oracle 10g to end a user session correctly ?
Thanks for your assistance.

http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_2013.htm#i2053602
I think DISCONNECT SESSION Clause is what you are looking for.
Let us know if this is not the case.

How to clear session in JSP?

I searched yahoo, and found that it seemed not easy to force invalid the session using jsp, compared to php just three lines:
session_start();
session_unset();
session_destroy();
How to acheive this using JSP? Must I follow these (quite complex) steps like this one?
http://sdc.sun.co.jp/javasystem/technote/cluster/jsp.html
Any simplier method?
Thx.

Not at all, it's very simple.

session.removeAttribute("attributeName");

Want to get ApEx session in JSP

Hi Pals,
From my ApEx application, I am calling a JSP by providing a direct URL.
THe JSP does some specific function here.
If the user get the JSP url by right click and view source, they can very well use this outside my ApEx application.
I want to apply security like, the JSP url only works inside my ApEx application.
My thought, if I can share ApEx session with JSP session I can impose the security check in JSP level.
Any idea would be appreciable.

Hi,
Im using below method to call jsp page and passing UserName, application id and Session as
<iframe src="http://apex.oracle.com/pls/otn/...javaapplication.jsp?userId=&USER.&appId=&APP_ID.&sessId=&SESSION."></iframe>
Vailidation is done against the table "wwv_flow_sessions$" of schema : flows_030100 ,whether those values are exist in table.
But if user is already logged into apex application, he can run the jsp independantly taking the url from "view source".
Im also looking for more solid validation
Regards,
Benz
