Session.putValue() and session.setAttribute
do I have to use session.putValue() before using session.setAttribute() and session.getAttribute() ?
becuase I have one JSP page include one form (action=TheSameJspFile.JSP) several Submit bottuns each Bottun has its Value.
in the JSP I request the submit value and depends on it doing stuff ...
each Value I have to get and to set a session Attribute, if I want to putValue it will delete the old value.
how can I solve this?
You need to store something in the session before you can retrieve it.
So, you need to do a setAttribute() to place something in the session. Then you use getAttribute() to retrieve it. DO NOT use putValue as it is deprecated and has been replaced by setAttribute(). DO NOT use getValue() as it is deprecated and has been replaced by getAttribute().

Session Id, Unified Session ID and session shadowing
Hi,
It looks like we've got a problem with session shadowing in our 2012R2 deployment. Trying to shadow a session from server manager returns an error "the session identification does not specify a valid session", but running a command "Mstsc.exe
/v:RDS2012 /shadow:2 /noConsentPrompt" and using SessionID opens correct session without a problem. I noticed that there are two different ID's for each session, SessionID and UnifiedSessionID which are different. When I'm trying to shadow a Uinified
one I'm receiving an error, but with SessionID it opens it. I can see that server manager is using UnifiedSessionID and that's why I can't open a shadowing session with GUI.
Is there a way to sort it out so we will be able to shadow a session from Server Manager?
Best,

Upload file with iframe loos session user and session id in wwv_flow_files
Hello every one, hope someone could help us with this problem.
What we are trying to do is to upload a file from a jquery dialog in a appex page by redirecting the POST action of the wwvFlowForm to the iframe.
*1. In the javascript there is the function call to open my modal window with the input*
function add_fichier_form(numeroProjet,idCat){
$("#div_upload_fichier").dialog(
modal : true ,
autoOpen : false ,
resizable: false ,
width: 700
$('#div_upload_fichier').parent().appendTo('#div_base');
$('#upload_button').unbind('click').click(function(){
if ($('#P4010_FILE_FICHIER').val() != '') {
$('#upload_iframe_v2').unbind('load').load(function () {
$('#upload_status').html(' déplacement du fichier...');
// move the file
$('#upload_status').html('Fichier transféré avec succès');
//file transfer ok
//calling the javascript function to add everything in my own table;
//we see the file in the wwv_flow_file_objects$ without
add_fichier_form_db();
// set the form target to the iframe, submit, then remove the target
$('#wwvFlowForm').attr('target','upload_iframe_v2').submit().removeAttr('target');
$('#upload_status').html(' Téléchargement du fichier...');
}else {
alert('Veuillez sélectionner un fichier');
$("#div_upload_fichier").dialog("option", "title", "Ajout d'un fichier");
$("#div_upload_fichier").dialog("open");
}*2. At this point we see the file in the table but without the user and session credential*
select *
from wwv_flow_file_objects$
The result is that the field security_group_id is assign to 0 AND created_by = APEX_PUBLIC_USER
*3. add_fichier_form_db(); the javascript function making the ajax call to a procedure plsql*
function add_fichier_form_db(){
//alert ('Dasn fichier form db');

vIdCat = document.getElementById('P4010_CAT_ID').value;
vFichierNom = document.getElementById('P4010_NOM_FICHIER').value;
vFichierDesc = document.getElementById('P4010_DESC_FICHIER').value;
vFichierFile = document.getElementById('P4010_FILE_FICHIER_NAME').value;

Thanks in advance
jocelynFinally we find what was wrong so i give you the solution.
In the javascript on the function add_fichier_form
We need to append the div of the form to the default form of apex wwvFlowForm
so the line*
$('#div_upload_fichier').parent().appendTo('#div_base');
should be change to*
$('#div_upload_fichier').parent().appendTo('#wwvFlowForm');Edited by: jocbed on 2012-01-26 11:08 -
Session.removeAttribute and session.invalidate
I pass a scoped object from one JSP #1 to JSP #2 in a session.
In JSP #1, I did:
<c:set var="cr" value="${articleForm.creator}" scope="session"/>In JSP #2, I did:
<bean:define id="author" name="cr" scope="session" type="java.lang.String"/>
<html:text property="receiver" value="<%=author%>" size="82" maxlength="25" tabindex="1"/>Immediately after I output the value, I want to remove the object from the session. I have two questions:
1. which one of the following should I do:
session.removeAttribute( "cr" );or
session.removerAttribute( "author" );or
session.removeAttribute( "receiver" );2. Do I have to invalidate the session; i.e. session.invalidate(); after all the objects in the session are removed?I pass a scoped object from one JSP #1 to JSP #2 in a session.
In JSP #1, I did:

Session timeout and session.invalidate() -- are they the same?
I was just wondering when a session timeout occurs (either by setting the session-timeout in web.xml or the server's default timeout), is the session automatically invalidated? Or should we call setMaxInactiveInterval() instead? Or is calling session.invalidate() the only way to invalidate a session?
Hello all,
Both are same in terms of functionality, but if you use both of them like
1: You specified the tag sessionTimeout and
2: in your program the session.maxInactiveIntervalTime( value ) here if the value is(we gave it in terms of seconds like for 40 minutes we give 2400) then the program code will override the value previously set in web.xml
Thanks

This problem seems to be there in version5.1 too , as per another post , it
seems to be solved in WLS5.1 sp 8
Could anyone pls confirm in which patch in WLS 4.5.1 is the problem

Under Excel Service Application --> session management; what is the difference between Session timeout and Short Session timeout?
Any call made from the API will automatically be set to the “Session Timeout” period, no matter
what. Calls made from EWA (Excel Web Access) will get the “Short Session Timeout” period assigned to it initially.

Session/jstl and load balancing - need expert advice
After user loggs in, I am getting locale from db and storing it inside userSession along with userLogin. Inside jsp using <fmt> tag to display locale based resource property.
HttpSession userSession = request.getSession(true);
userSession.setAttribute("UserLogin", oRS.getString("user_login"));
Config.set(userSession, Config.FMT_LOCALE, currentLocale);Also using filter after login page to check for User Session. Currently all working fine .
But if i want to make use of load balancing, whether still it will work?
1)I understand that if i depend on network config i.e. session request sticks to one server then i believe shld not be a problem
2)But if that is not the choice then what else ? Client want to make use of serialization technique. I do not know much about it, how to implement it, any sample is greatly appreciated.
3)what about jstl Config.set(..) whether any changes needed here?
4)Do i need to change filter code.
Pls pls help me, i really need expert advice on this.
regards
Manisha1)If i want cluster server to replicate the session
then all attributes saved in the session have to be
serializable.yes.
2)In docs it is mentioned
Use setAttribute to Change Session State
In an HTTP servlet that implements
javax.servlet.http.HttpSession, use
HttpSession.setAttribute (which replaces the
deprecated putValue) to change attributes in a
session object. If you set attributes in a session
object with setAttribute, the object and its
attributes are replicated in a cluster using
in-memory replication. If you use other set methods
to change objects within a session, WebLogic Server
does not replicate those changes. Every time a change
is made to an object that is in the session,
setAttribute() should be called to update that object
across the cluster.
Whether it means that if I want to store a object
(which is serializable) e.g. 'String' inside session
and use setAttribute() method then I do not need to
make that object implicitly serializable?No, you still need the objects to be serializable. -

Session migration and replication
Hi All,
I am having a hard time in configuring my application for HTTP session migration. Our weblogic server consists of two managed servers running in same cluster. Each server has an Ehcache that stores some information of user with key as session ID and value as info object. In case, if a server needs restart, we would want to take this updated info Object from cache residing on server being restarted to another managed server within the same cluster.
I browsed through many documentations online. Most of them explained about session replication but not migration. so I followed replication (I don't want a real time sync up of HTTP session. I want it to migrate if something goes wrong with one of the managed server).
However, I could not achieve this task after following the steps to configure this feature. I would appreciate a lot if someone can help me figuring out the issue here.
Here is what I did.
1) Weblogic.xml
<session-descriptor>
<persistent-store-type>replicated_if_clustered</persistent-store-type>
</session-descriptor>
2) An implementation class of HttpSessionActivationListener, HttpSessionListener, HttSessionAttributeListener:
public void sessionDidActivate(HttpSessionEvent sessionEvent) {
// NEVER GETS CALLED
over here i would check if session has any attribute with name 'CACHE_ELEMENT'. If yes, then it is a migration case for current managed server
Log.info(UserCacheMigrationListener.class, "inside sessionDidActivate");//
public void sessionWillPassivate(HttpSessionEvent sessionEvent) {
// NEVER GETS CALLED
Over here I would set attribute 'CACHE_ELEMENT' so that it is available for target managed server when it's sessionDidActivate is called
Log.info(UserCacheMigrationListener.class, "inside sessionWillPassivate");
public void sessionCreated(HttpSessionEvent sessionEvent) {
THIS GETS CALLED! and I set the following attribute
sessionEvent.getHttpSession().setAttribute(UserCacheMigrationListener.class.getName(), this);
public void sessionDestroyed(HttpSessionEvent arg0) {
THIS GETS CALLED!
public void valueBound(HttpSessionBindingEvent arg0) {
THIS GETS CALLED! WHICH MEANS THAT I WAS ABLE TO setAttribute this class's instance in sessionCreatedMethod
In the above code, the setAttribute method used inside the sessionCreated(..) method successfully sets the attribute to this session. This is apparent because valueBound(..) method is called when session is created. But why does it not call the sessionWillActivate method???
3.) An entry in web.xml for this listener.
<listener>
<listener-class>com.xyz.UserCacheMigrationListener</listener-class>
</listener>
4) from weblogic config.xml. I am copying all meaning stuffs from config.xml to describe as much as I can.

Session: Waiting and Working Chart
I am using OEM 10g (Grid control) to monitor my database.
But I don know what does the Y axis on the chart (Session: Waiting and Working) mean ?
Thanks for your help.
Note: Click Home page -> Database -> Performance -> Sessions: Waiting and Working.2 store the user name in the session to display as a welcome message to the user when they are logged in.]
in class where you match the username and password .if given user is exist in records then set it into session
HttpSession session =request.getSession();
session.setAttribute("",);
3 tell the user they dont exist in the database or that there password is wrong and give them the option to either A) reset the password or B) create a user
in same class if user does not exist the redirect the request to different pages in that pages you put these two like A) reset the password or B) create a user -
Hi,
I have questions about "Accounting-Start" and "Accounting-Stop".
1.If a NAS configured to have a primary and a backup RADIUS server. To start with all the “Accounting-Start” records will be in the primary RADIUS server. Later on the primary server goes down (Primary server won’t tell the NAS?). When sessions stop, the NAS sends the “Accounting-Stop” to the secondary. I understand the “Start-Stop” record with the same “user name” and “session-id” ideally should be recorded in the same server. If this situation happens what should both the NAS and RADIUS server do?
2.A NAS configured to have a primary and backup RADIUS server. To start with all the “Accounting-Start” records will be in the primary RADIUS server. Later on the administrator decided to change the primary server (as there are problems with the previous primary). sessions stop, the NAS sends the “Accounting-Stop” to the new primary. This ends up the “Accounting-Start” and “Accounting-Stop” with the same “user name” and “session Id” in two RADIUS servers.
To summarize, how to avoid the ”start-stop” pair ends up in different servers ? If it does, is it an issue for RADIUS application ?
Cheers,

Cheers,vignesh and BalusC,
following is the code in front controller's doFilter method. is this not thread safe?
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
HttpSession session = req.getSession();
somepackage.User user;
if(session.getAttribute("user") == null){
user = new somepackage.User();
session.setAttribute("user", user);
}else{
user = (somepackage.User) session.getAttribute("user");
}user object maintains all information about a user. if it is in session scope, everything should work fine.
another observation is after some time of usage, both people in different systems are getting same session.getId()
in my logout page i am using
session.invalidate();
thanks,

</HTML>hi all,
thanx a lot for your help,specially hari52
hari52 strangely enough the code started working,but
now i have another problem
after a while my server hangs or gets shutdown ,a
message is shown as
"java.exe has generated error and will be shutdown"
i know that more connections can be a prob. but i
make sure that connections r closed on each page,also
i am a newbie and do not have the time at present to
learn abt. connection pool ,can this problem be
solved easily?
it would be a great help again on your part,
thanx again,You remove the System.exit(1) line from the code inside the catch block
and try again. That's the reason tomcat getting down. System.exit(1) should not be used inside jsp. it will make the underlaying Servlet Engine to shutdown. -
Oracle portal and session tracking
Friend I am working in JDeveloper in my PC and my statements in with setAttribute and getAttribute does work ,but the same statement doesn't work when I use this jsp as my portlet.The error is given below.So portal doesnot support this method's ?
Method getAttribute(java.lang.String) not found in interface javax.servlet.http.HttpSession.
OConnect = (Connect)Session.getAttribute("OConnect");
Method getAttribute(java.lang.String) not found in interface javax.servlet.http.HttpSession.
OMainMenu = (MainMenu)Session.getAttribute("OMainMenu");
Method setAttribute(java.lang.String, ccrspackage.Connect) not found in interface javax.servlet.http.HttpSession.
Session.setAttribute("OConnect",OConnect);
Method setAttribute(java.lang.String, ccrspackage.MainMenu) not found in interface javax.servlet.http.HttpSession.
Session.setAttribute("OMainMenu",OMainMenu);
please help

%>If Oracle Portal is running on Apache/Jserv, which is the only application server it runs on as far as I know, then that's your problem. JDeveloper uses one of the newer Servlet specificatione, 2.1 or 2.2, where as Jserv is using a very old one. 2.0, which doesn't support the session.setAttribute() method.
I happen to know a little bit about portal and the JPDK. You do have the option of using the ProviderSession object that is provided by the JPDK PortletRenderRequest.getSession() method. I believe they have a setAttribute() method in there. In fact, if you want this object in the user's session, then you HAVE to use the ProviderSession from the JPDK.
There are some other configurations you have to set to use this, you must specify to use session in your provider.xml, and you must also set the login frequency on the provider registration page to "Once per user session".

JSF - spring - hibernate and session
Hi,
I'm currently using hibernate spring and JSF
1/ the first problem
In the JSF common header page I try to test if a bean is in the session scope in order to show login or logout link, and the test always fails : the logout link is always displayed.
the JSF page :
<f:subview id="header" >
<h:form id="headerForm">
<table cellspacing="0" width="100%">
<tr>
<td align="left" valign="middle">
<a href="front.jsf"><img border="0" src="images/logo1.jpg"/></a>
</td>
<td align="right" valign="middle"> <br>
<!--<a href="front.jsf" rendered="#"> Accueil<</a> -->
<c:choose>
<c:when test="${empty sessionScope.accountBean}">
<h:commandLink action="Sign on">
<h:outputText value="Sign on"/>
</h:commandLink>
</c:when>
<c:otherwise>
<h:commandLink id ="logout" action="#{accountBean.logoutAction}" >
<h:outputText value="log out"/>
</h:commandLink>
</c:otherwise>
</c:choose>
</td>
</tr>
</table>
<table cellspacing="0" width="100%">

HttpSession session = (HttpSession) fc.getExternalContext().getSession(false);
session.invalidate();
this.logger.debug("Logout successfully.");

<value>#{adminService}</value>
</managed-property>2/ the second problem :
my application shows a list of datas.
I log on the application , i update this list outside the application ( by using sql command) , i try to list my data using the application : the application does not reflect the modifications. I logout using the log out link, then i log on and the application does not reflect the modifications.
what happens?
How could I resove these problems.
How can i logout properly?
how can i show logout link when the user is logged in? and hide the log out link when the user is logout
Thanks.It depends on how you want to reprecate the session btwn instances or cluters
there are three kinds File System, Memory to Memory, HA
You can configure it from this property in the admin console
