Problem accessing session variables in JSP

          Hi all,
          i am retrieving the value of session variables in a JSP page. the session varibale
          is set at the
          server side. sometimes the jsp is able to retrieve the value and sometimes it
          doesn't.
          Thanks & Regards
          Tarun

if getAttribute return null so there is no such session attribute,anyway
          check your browser if cookies are enabled.

Problem accessing session variable from jsp

Hi!
I get an error retrieving a session variable from inside a JSP declaration scriptlet....
Something like this code in a JSP page:
<%!
public void funtion1() {
String parameter1 = session.getAttribute("parameter1");
%>I have seen that I have available getContextServer() method and from there I could call getAttribute("parameter1") . But the thing is that the attribute I want to retrieve was stored in session by another Jsp page.
Any solutions are welcome
Cheers
Victor

Appropriately the above is one the reasons also You cannot use JSP implicit objects from the declaration tag. However we can think of a small workaround by passing the reference like the one discussed below
<%!public void funtion1(HttpSession session) {
String parameter1 = session.getAttribute("parameter1").toString();
}%>
<% funtion1(session);%>Hope that helps :)

Problems accessing session variables from a pop-up

I am working on a webapp and I when I click on a certain button I need to have a pop-up appear that will either prompt a user to enter log-in info if they haven't already, otherwise the pop-up just needs to display a report. Users can navigate around on the main page and select various reports so multiple pop-ups could possibly be opened. When a user logs in I save the login info in session variables, but for some reason whenever I click to have another pop-up open it always says that my session variables are null. Is there a way to have more global session variables so that multiple windows (the pop-ups) can touch session variables? Would there be a way to pass the login info in session variables back to the main page and then pass those session variables back out to each pop-up that opens? Thanks so much.

Have you got session cookies enabled?
The most common way to keep track of the session id is via a session cookie.
This cookie gets shared by all windows of the same browser session.
You are opening these pop-up windows with window.open?
Print out the session id <%= session.getId() %> on each page to see if it is the same.

Accessing session variables

Hi ,
I have session variable defined using portals (forms or plsql portlets).
Can i access these variables using jsp portlets ??
This is an urgent requirement ..
Regards,
Vijaya

"145822",
If your application with application id 100, for example, uses a common authentication scheme with application 200 (using the same cookie name in the case of an HTML DB style authentication scheme), then the two applications can run in the same session. A potential benefit of this, even if the two apps are not intricately related, is that the user has only to authenticate once per new session and will have access to both apps. If you set it up this way, then app 100 can access app 200's items in the same session using this function from within app 100: htmldb.application.fetch_app_item(p_item=>'ITEM_NAME',p_app=>200);Scott

Accessing session variables with php

I am trying to access the session variable $_SESSION['MM_Username'] in one of my php pages, but it is somehow showing empty (i.e it does not contain the username that was entered during login).
I checked and confirmed that my login.php function is properly setting the MM_Username session variable by echoing it from the login function.
So why can't I read it from another php file in the same session? Do I need to do something else before the session variables can
be properly read from any php file in the same session? Any help would be appreciated.

Here is a test code I am using to access the session variable $_SESSION['MM_username'] from the php page test.php. But it is not working.
I get an empty string all the time for $username. Can any one see something wrong with this code?
<?php require_once('Connections/MyTestingConn.php'); ?>
<?php session_start(); ?>
<?php
$username = "-1";
if (isset($_SESSION['MM_username'])) {
$username = $_SESSION['MM_username'];
echo $username;
else
echo "Eror: can not access session variable";
?>

Access Session variable inside Transaction

Hi All,
Is it possible to access session variables inside Transaction.
Create session variable.
Update session variable value
acccess Session variable.
(user session)
Regards,
Sachin

Hi Sachin,
Here is the snapshot:
1. Take session variable in a local JS variable in HTML page.
2. Create a transaction with a input type variable in Transaction Properties.
3. Create a Xacute query and link the above transaction.
4. Creata a iCommand applet on HTML page and link the query template:
<PARAM NAME="QueryTemplate" VALUE=".../QueryName">
Call the function in the below way in HTML:
Applet.getQueryObject().setParam(1,vaiable)
So, the session variable will go to TRX (BLT) and perform the operations as per your need..
You can pass it to other TRX by the same way.
To fetch the value: Create output type variable in TRX 2. Create Xacute query.
Get the value with : Applet.getValue(1,1)
Hope it is useful.
Best Regards,
Kedar

Access session variable in Java Function in JSP

Hi Experts !!
I am developing an application using STRUTS MVC...
Very sorry if u have problem understanding my question, i ll try to improve... and sorry if i can't post codes here
Basic question is ....
I want to open a word document on pageLoad of JSP, the word document is not a single document, there is a form in which there is a "name" and "template" whenever user clicks on a button there is one action attached to it which creates a copy of that template in a different folder.. on the next page OnLoad i want to open that particular document. for that i have created a variable and also have set in the session, just want to access it in the below code.
I have a formbean in which i have a variable, the scope is session, that variable i have put it in session also. but i want to access that variable in a "java function" in JSP so that "onLoad" page that function should work.
JSP---
<script type="text/javascript">
function openDocument() {
var w = new ActiveXObject("Word.Application");
var docText;
var obj;
var a;
if (w != null) {
w.Visible = true;
obj = w.Documents.Open(I HAVE TO ACCESS THAT VARIABLE HERE);
</script>
FORMBEAN----
public class CreateSOWFormBean extends ActionForm {
private String workflowName;
private String comment;
private String sowTemplate;
private String sowFileCreated;
public String getSowFileCreated() {
return sowFileCreated;
public void setSowFileCreated(String sowFileCreated) {
this.sowFileCreated = sowFileCreated;
sowFileCreated is the variable that i have accessed in session and that value i have to pass in that function in JSP....
I am aware of something like
obj = w.Documents.Open(<%'sowFileCreated'%>);
but i m not sure how to write....
Plz help.....

If you're working under a framework like struts you should definitely be using JSTL tags rather than scriptlet code to access variables within the page. With JSTL code <% codes can be almost entirely avoided.
To transfer a value from a Servlet to a JSP don't use a session variable, use a request attribute. Session variables should only be used when values have to survive from one transaction to another.
You can write something like:
obj = w.Documents.open('<c:out value="${openURL}"/>');in the Javascript portion of your JSP.
Just beware of potential problems with quotes. The coresponding code in the Servlet would be like:
request.setAttribute("openURL", openUrl);

Problem with session variable

Hi,
After I insert a record into my MS Access database, it seems
to me that the session variable got destroyed so the next page
display the session variable as undefined. Has anyone have similar
problem? If so, how to work around that?
Thanks.

but its leading to jsp page error...For starters: never, never, ignore errors (exceptions and stacktraces). Those contain very, very, worthful information about the cause of the problem and what exactly went wrong. This way you can easily trackback the problem and solve it.
If you're unable to think logically and smart so that you can interpret the error yourself, if necessary with help of Google, then post it here. Then we'll tell you about the actual problem and possible soltions.
At any way:
iam displaying some data in a table using resultset object,now at the same time iam using to session variable to use the resultset object in my other applications...This already doesn't sound very good. You should never pass expensive resources around like that. You should acquire and close the Connection, (Prepared)Statement and ResultSet in the shortest possible scope. Preferably already in the same method as where you query the data.

Problem in session variables

hi ,
Is it not correct to assume that ones we close the browser the session losts and all the session variables also?
Actually i have design an authentication page which takes userid and password from user and supply this to servlet which after authentication sets a variable "validity" in session to true.
And in every other jsp page first i m checking this variableis true or not if not then i m redirecting it to authentication page with this tag
<jsp:forward page="authentication.jsp" />
now if i have authenticated correctly and close browser and try to access other pages directly then browser allows me to access any page and infact when i print "validity" variable from session then it prints true. That means even after closing the browsing session remains.
I tried to print session id then after opening a new browser it is showing the same browser.
In web.xml file i have mentioned the session time to 60 minutes . Is it because of this?. If it then how these standard sites sun, yahoo maintains session time out as well as browser dependent session.
Right now what i have to do is before setting the variable i have reset the variable to null. But wher shud i reset the validity variable . in destroy method?
manish

Your problem is not due to session time out in the xml
file.
I think whenever you close your browser the session
does not exists.
Remember to invalidate the session while logging off.
It should workThat is not true. The session will exist for as long as the session timout option is set. Although invalidating the session at logoff is a good idea, there is no real method to force people to log off when the leave your site/close the browser.
There are a couple of possibilities why the session would still be used after a browser is closed, although normal behavior is to create a new one. The main reason is because the cookie on the browser that maintains the jsessionid is not destroyed. This often occurs in browsers like NS 7 with a "quick-load" app running in the taskbar area (next to the clock). These little parts of the application never close, and hold on to browser cache and cookies, so as to make it quicker to open and surf.
How do you ge around this? I do not know, except perhaps by preventing the session from using cookies for tracking...

Purchased ColdFusion 10: Having problem with session variables

My Dept. has just bought CF10 and I'm finally updating my existing web app to CF10 from CF8. My First Problem with CF10 is using session variables.
When using the lower version of CF (since CF 4 to 8) I have never had any problem setting up session variables and getting or using these variables in other pages after a successful login but with CF 10 it seems setting session variables and using them in other pages are a major problems. I'm not sure where have I done wrong in the codes.
First I'm setting the session in my Application.cfc This way:
<cfcomponent displayname="Application" output="true">
<cfset THIS.Name ="MyNewApp"/>
<cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,20,0) />
<cfset THIS.SessionManagement ="YES"/>
<cfset THIS.SessionTimeout = CreateTimeSpan( 0, 0, 20, 0 ) />
<cfset THIS.SetClientCookies = false />
<cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">
<cfset application.Main_DSN = "TESTDB">
<cfreturn true />
</cffunction>
<cffunction name="onApplicationEnd" output="false">
      <cfargument name="applicationScope" required="true">
    </cffunction>
<cffunction name="OnSessionStart" access="public" returntype="void" output="false" hint="Fires when user session initializes.">
<cfset session.loggedin = "NO">
<cfset session.username = "">
<cfset session.userrights = "">
<cfset session.usergroup = "">
</cffunction>
</cfcomponent>
After login, user is validated and set values to those session.variables:
........user validation codes here......................
<cfif mylogin NEQ true>
      <cflocation url="/login/login.cfm">
      <cfabort
<cfelse>
      <cfset session.loggedin="Yes">
      <cfset session.username="#Trim(Form.username)#">
     <CFSET qUserRights = LoginObj.getUserRights('#Trim(Form.username)#')>
     <cfset session.userrights = qUserRights>
    <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>
        <cfloop query="qUserGroup">
           <cfset session.usergroup = user_group>
           <cfbreak>
        </cfloop>
    
   <cfdump var="#session.loggedin#">
   <cfdump var="#session.username#">
   <cfdump var="#session.userright#">
   <cfdump var="#session.usergroup#">
</cfif>
In index.cfm, Before Login I got:
session.loggedin = NO
session.username = ["empty string"]
session.userrights = ["empty string"]
session.usergroup = ["empty string"]
After a successful Login:
session.loggedin = NO
session.username = ["empty string"]
session.userrights = ["empty string"]
session.usergroup = ["empty string"]
Have I done something wrong? These codes work on CF8. Please help.
I need to mentioned:
CF10 is in Linux and my web app is under https not http. But these session variables should be shared bentween http and https because some older application are still in http.

On which page is the following code?
After login, user is validated and set values to those session.variables:
........user validation codes here......................
<cfif mylogin NEQ true>
      <cflocation url="/login/login.cfm">
      <cfabort
<cfelse>
      <cfset session.loggedin="Yes">
      <cfset session.username="#Trim(Form.username)#">
     <CFSET qUserRights = LoginObj.getUserRights('#Trim(Form.username)#')>
     <cfset session.userrights = qUserRights>
    <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>
        <cfloop query="qUserGroup">
           <cfset session.usergroup = user_group>
           <cfbreak>
        </cfloop>
    
   <cfdump var="#session.loggedin#">
   <cfdump var="#session.username#">
   <cfdump var="#session.userright#">
   <cfdump var="#session.usergroup#">

Access Session Variable

Hi All,
I am using cutom autentication schema called "My Auth Scheme". I want to hide some of the menu options (Tree List) based on the Role Type.
Could anybody give me any pointer about how to acheive this. And most importantly how to access the session variable (Though I am not even sure about Role Type is going into session or not). Please guide me..
Regards
Amit Arora

Amit,
You're using a lot of terms that you have not defined:
I am using cutom autentication schema called "My Auth Scheme". It's an authentication scheme but what is the relevance of it being custom (in what way is it custom and how is that relevant?) and why do we care what you named it?
I want to hide some of the menu options (Tree List) based on the Role Type. "Role Type" -- What is that?
And most importantly how to access the session variable ...What do you mean? What session variable?
Please describe your exact functional requirements, what you are doing now to achieve them and how your actual results differ from the expected results. Also, show us all of the code you are using and demonstrate the problem on apex.oracle.com so we can see exactly what you're trying to do.

Problem with Session variable initialization block

Hi,
I'm getting strange results when using session variables in my repository files.
I have created session variables as specified in the document which is available at
http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/bi_admin/biadmin.html
The main problem getting with the system session variable (USER) in the select statement.
My select statement is as follows,
select ':USER',case when upper(':USER') = 'KUMAR' then 'APR-05' end from Dual
The problem is while logging into the BI Answers it is allowing all the invalid users to login who does not exist.
when i remove the quotes and simply use :USER in the select statement it is not allowing the invalid users to login but giving error while displaying the results.
when i remove the user variable from select statement its giving correct results.
Can i know what is causing the problem.
Thanks,
Kumar.

Problem retrieving Session variables in Flex from Coldfusion

For about a year I've been using a cfc that allows me to remote call from within Flex to retrieve session-level variables. I much prefer this to using FlashVars because with the remote call the session values don't show up in the page source.
This was working fine when I was using an Application.cfm file to manage my Coldfusion pages. However when I switched to using an Application.cfc file, the cfc stopped working. Neither the cfc or the cfm file contain any code to manage these session variables (they are set in other pages), so the only real difference seems to be changing from Application.cfm to Application.cfc.
Any thoughts why? Thanks.

Ok, this is resolved.
The problem seems to have been related to the scope of Application.cfc and Application.cfm. The directory which contained the cfc files had an Application.cfm controlling the session, while the directory with the pages that included the flex swf files had an Application.cfc file. Apparently these two don't talk to each other.
The solution is to use either Application.cfc or Application.cfm files, but not to mix them. In other words, use either -- but be consistent.
