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 :)

Retrieving a session variable from a php script and putting it in an applet

I have a chat applet and i'm trying to have a session variable in one my php scripts be setted onto the user area of my chat. Would it start out by doing this?
<object codetype="application/java"

No.
Use the parameter tags.

Passing Session Variable from PHP to Applet

I'm trying to pass a session variable from a PHP script to a third party applet. The applet needs to accept the variable as a string into a parameter. I think the htnl has to be dynamically created to turn the session variable into a string for the parameter value. Any suggestions ?

This is really a PHP question. You might get better results on a PHP forum.

Servlet/PHP Session Variables

Hello Everyone,
I am running an servlet that requires authentication. The authentication is done by a PHP program, while the heavy lifting is done by a servlet. How do I pass a session variable from my php to my servlet so that my servlet knows the user is allowed. I have tried
Object done = session.getAttribute("loggedIn");
with "loggedIn" being set by my php file, but done is always null. Any help is greatly appreciated especially if it is cookie free.
Sincerely,
Chem E

You could consider the following solution: on click of the link, fire a specific Ajaxical request from the server where PHP runs to the server where Java runs to obtain an lengthy and unique key which expires within a few seconds, use JS+DOM to add that key as a query parameter to the link value and after opening the link let the Java side determine the key and handle accordingly.
You only need to write code so that it is hack safe.

Help with session variable please - CS5.5 PHP

Hi all,
I am needing a little assistance with using a session variable and hope that someone may point me in the right direction.
I have created a PHP page that uses the Dreamweaver 'User Authentication' feature, and the basics of this works fine, directing a user to the correct pages depending on whether they are or are not a valid user. I would like however to personalise the 'valid user' page with the persons Username as entered in the User Authentication table....a seemingly simple task using a session variable, but one that I just don't seem to be able to get working!
The code generated for the UA on page 1 is as follows:
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
session_start();
$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
$_SESSION['PrevUrl'] = $_GET['accesscheck'];
if (isset($_POST['txtfirst_name'])) {
$loginUsername=$_POST['txtfirst_name'];
$password=$_POST['txtsurname'];
$MM_fldUserAuthorization = "";
$MM_redirectLoginSuccess = "member_update.php";
$MM_redirectLoginFailed = "login.php";
$MM_redirecttoReferrer = false;
mysql_select_db($database_panto, $panto);
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND surname=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
$LoginRS = mysql_query($LoginRS__query, $panto) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
     $loginStrGroup = "";
    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
   $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
    header("Location: " . $MM_redirectLoginSuccess );
else {
    header("Location: ". $MM_redirectLoginFailed );
?>
Firstly, the text highlighted in red above appears to be setting the session variable that I require. Is This correct?
If so, what is the code that I need to place in page 2 to use that session variable? or
Do I need to do something else on page 1 to properly assign the session variable?
Would really appreciate your expertise
Mark

It looks as though you've set the columns incorrectly in the User Authentication server behavior. This is the SQL query that checks the user's credentials:
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND surname=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
You're looking for firstname and surname, whereas you should be looking for the user's login name and password.
$_SESSION['MM_Username'] is a session variable that stores the user's login name. To use it in a subsequent page, all that's needed is for the page to begin with session_start(). You can then echo the value to display it.
If you want to display the person's real name, you need to create a recordset in the second page using $_SESSION['MM_Username'] to find the firstname and surname. Alternatively, you can edit the existing code like this (I've copied only part of it):
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND password=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
$LoginRS = mysql_query($LoginRS__query, $panto) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
     $loginStrGroup = "";
    $row = mysql_fetch_assoc($LoginRS);
     $_SESSION['full_name'] = $row['firstname'] . ' ' . $row['surname'];
    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
   $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
You can then use $_SESSION['full_name'] in a subsequent page that begins with session_start().

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);

Jsp session variable in javascript

hi,
i want use a jsp session variable inside a javascript code, for this i am using the following function,
function checkList()
<% String ecode1=(String)session.getAttribute("e_numb"); %>
var code=<%=ecode1%>
alert (code)
this is showing an error can any one please help me,
thanks
saurabh

You have ',%String ecode1' within the javascript. JSP will not recognize 'String' as a java class unless you import the String class. Something like <%@ page import = "java.util.* " %> Incorrect. String is part of java.lang, which is always imported into a java class.
Most probably what is missing in the javascript is
- missing quotes ? Not sure if this value is meant to be interpreted as a number or not.
- missing semicolon
function checkList()
<% String ecode1=(String)session.getAttribute("e_numb"); %>
var code="<%=ecode1%>";
alert (code);
}Lets assume that the value of e_numb is "42"
after running this as a jsp, it should produce the following on the resulting html page. You can see it by viewing the source.
function checkList()
var code="42";
alert (code);
}Check that to see it has produced valid javascript
