Require a Session variable

Hi
how a variable in a servlet in the others servlets can use?
think you

Hi
if you dlike to send em over a httprequest or so you always first have to define the as follow.
req.getSession().setAttribute("sessionname", "value");
to retrieve the session values you use the getAttribute method!
String sessionsample = req.getSession().getAttribute("sessionname");
Cyrill

Urgent help required...for replacing JSP session variables

I am trying to enhance the performance of a j2ee based webapp which use session variables to store the data...
Is there any alternative for session variables..The project is based on j2ee-Struts frame work..But the amount of code maintainance should be minimum ....so i can't create beanforms for all these data...
Is there any XML based methods available...??

ok... thanks... i created a fla file and inthe action script
pasted the following code

To pass new session variable value to stored proc before running a report.

Hi,
Below is summary of the report requirement -
Database level design
1. Created a view and a global temporary table (GTT)
2. Created an Oracle package procedure to accept from and to business dates on basis of which it will fetch, process and populate the GTT.
Repository level design
1. Created a business model containing the view and the GTT (mentioned above)
2. Created two SESSION variables "from_dt" and "to_dt" to be initialized by their respective init blocks. Each of the variable is initialized with a DATE column value (of type DATETIME) from a database lookup table. I have also set the option "Enable that variable to be set by any user" for both variables.
Query for these variables :
from_dt = select from_date from <table>
to_dt = select add_months(from_date,12) from <table>
Presentation level design
1. Using a text box, i display the default/initialized values of these variables like this -
Current business date:@{biServer.variables['NQ_SESSION.from_dt']} Future business dt:@{biServer.variables['NQ_SESSION.to_dt']}
Dates get displayed in YYYY-MM-DD 00:00:00 format
The text msg displays these default dates and allows the user to specift different date range for which i create prompts as shown below.
2. Using any random two columns of date type from the business model, i create two date dashboard prompts with labels "From Dt" and "To Dt".
i select Calender Controls for both; setting Default To = Report Defaults.
The Set Variable is set to Presentation variables - such that pv_from_dt maps to "From Dt" and pv_to_dt maps to "To Dt".
3. i create the report using the business model created above. In the report "Advanced Tab" => "Prefix" field i specify the following -
SET VARIABLE from_dt='@{pv_from_dt}',to_dt='@{pv_to_dt}';
Note : The logic here is to display the default dates and allow user to specify different date values which will be stored in presentation variables.
If the user does specify different "from dt" and "to dt" values, then using the presentation variables, i want to "write" back these new values to the corresponding session variables mentioned above.
If the user does not specify different date range, then the default/initialized dates must be considered.
I also display the default and new date values in the report title.
Back to Repository level design
To execute the stored procedure that will load the GTT before running the report I need to pass two date parameters to the stored procedure on basis of which it will fetch data, process and populate the GTT.
In the Connection Pool --> Connection Script Tab --> Execute before query, I wrote the below query using the repository variables FROM_DT and TO_DT to execute the procedure -
DECLARE
v_from_dt date;
v_to_dt date;
BEGIN
v_from_dt := VALUEOF(From_Dt);
v_to_dt := VALUEOF(To_Dt);
package_name1.package_body(v_from_dt,v_to_dt);
END;
Now when i try to run the report i get the following error :
[nQSError: 10058] A general error has occurred. [nQSError: 23006] The session variable, NQ_SESSION.to_dt, has no value definition. (HY000)..
Need help on this.
Is it possible to "write back" a new value to a session variable ?
Any other alternatives.
Thanks

Sandeep, I found a several topics where users describe saving values in DB through stored procedure or function. For example, [How to store OBIEE presentation level variable values in DB |http://forums.oracle.com/forums/thread.jspa?threadID=892006] I tried it and get an error
*10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 14551, message: ORA-14551: cannot perform a DML operation inside a query ORA-06512*
It's not a BI error. This error are generated by Oracle DB. If I write next:
SELECT MyPLSQLFunction(p1,p2) FROM DUAL
I get the same error.
Oracle doesn't allow DML operations in SELECT.
Did you relalize this feature yourself? Where did I mistake?

Javacard and session variables

Hello,
I'm trying to find a reasonable Javacard technique to handle "session variables" that must be kept between successive APDUs, but must be re-initialized on each card reset (and/or each time the application is selected); e.g. currently selected file, currently selected record, current session key, has the user PIN been verified...
Such variables are best held in RAM, since changing permanent (EEPROM or Flash) variables is so slow (and in the long run limiting the operational life of the card).
Examples in the Java Card Kit 2.2.2 (e.g. JavaPurseCrypto.java) manipulate session variables in the following way:
1) The programmers group session variables of basic type (Short, Byte, Boolean) according to type, and map each such variable at an explicit index of a vector (one per basic type used as session variable).
2) At install() time, each such vector, and each vector session variable, is explicitly allocated as a transient object, and this object is stored in a field of the application (in permanent memory), where it remains across resets.
3) Each use of a session variable of basic type is explicitly translated by the programmer into using the appropriately numbered element of the appropriate vector.
4) Vector session variables require no further syntactic juggling, but eat up an object descriptor worth of permanent data memory (EEPROM or Flash), and a function call + object affectation worth of applet-storage memory (EEPROM, Flash or ROM).
The preparatory phase goes:
public class MyApp extends Applet {
// transientShorts array indices
    final static byte      TN_IX = 0;
    final static byte      NEW_BALANCE_IX=(byte)TN_IX+1;
    final static byte      CURRENT_BALANCE_IX=(byte)NEW_BALANCE_IX+1;
    final static byte      AMOUNT_IX=(byte)CURRENT_BALANCE_IX+1;
    final static byte   TRANSACTION_TYPE_IX=(byte)AMOUNT_IX+1;
    final static byte     SELECTED_FILE_IX=(byte)TRANSACTION_TYPE_IX+1;
    final static byte   NUM_TRANSIENT_SHORTS=(byte)SELECTED_FILE_IX+1;
// transientBools array indices
    final static byte      TRANSACTION_INITIALIZED=0;
    final static byte      UPDATE_INITIALIZED=(byte)TRANSACTION_INITIALIZED+1;
    final static byte   NUM_TRANSIENT_BOOLS=(byte)UPDATE_INITIALIZED+1;
// remanent variables holding reference for transient variables
    private short[]     transientShorts;
    private boolean[]   transientBools;
    private byte[]      CAD_ID_array;
    private byte[]      byteArray8; // Signature work array
// install method
    public static void install( byte[] bArray, short bOffset, byte bLength ) {
         //Create transient objects.
        transientShorts = JCSystem.makeTransientShortArray( NUM_TRANSIENT_SHORTS,
            JCSystem.CLEAR_ON_DESELECT);
        transientBools = JCSystem.makeTransientBooleanArray( NUM_TRANSIENT_BOOLS,
            JCSystem.CLEAR_ON_DESELECT);
        CAD_ID_array = JCSystem.makeTransientByteArray( (short)4,
            JCSystem.CLEAR_ON_DESELECT);
        byteArray8 = JCSystem.makeTransientByteArray( (short)8,
            JCSystem.CLEAR_ON_DESELECT);
(..)and when it's time for usage, things go:
    if (transientShorts[SELECTED_FILE_IX] == (short)0)
        transientShorts[SELECTED_FILE_IX] == fid;
    transientBools[UPDATE_INITIALIZED] =
        sig.verify(MAC_buffer, (short)0, (short)10,
            byteArray8, START, SIGNATURE_LENGTH);I find this
a) Verbose and complex.
b) Error-prone: there is nothing to prevent the accidental use of transientShorts[UPDATE_INITIALIZED].
c) Wastefull of memory: each use of a basic-type state variable wastes some code; each vector state variable wastes an object-descriptor worth of permanent data memory, and code for its allocation.
d) Slow at runtime: each use of a "session variable", especially of a basic type, goes thru method invocation(s) which end up painfully slow (at least on some cards), to the point that for repeated uses, one often attain a nice speedup by caching a session variable, and/or transientShorts and the like, into local variables.
As an aside, I don't get if the true allocation of RAM occurs at install time (implying non-selected applications eat up RAM), or at application selection (implying hidden extra overhead).
I dream of an equivalent for the C idiom "struct of state variables". Are these issues discussed, in a Sun manual, or elsewhere? Is there a better way?
Other desperate questions: does a C compiler that output Javacard bytecode make sense/exists? Or a usable Javacard bytecode assembler?
Francois Grieu

Interesting post.
I don't have a solution to your problem, but caching the session variables arrays in local variable arrays is a good start. This should be only done when the applet is in context, e.g. selected or accessed through the shareable interface. This values should be written back to EEPROM at e.g. deselect or some other important point of time. Do you run into problems if a tear happens? I don't think so since the session variables should be transactional, and a defined point will commit a transaction.
Analyzing the bytecode is a good idea. I know of a view in JCOP Tools (Eclipse plugin) where you can analyze the bytecode and optimize it to your needs.

Using Session Variables for User Login - sometimes they don't persist... what am I doing wrong?

Hi all,
I'm running a site that requires user login. I approached the building of this site as almost a complete newb to CF (and dynamic coding in general), and it's been a great learing experience (with lots of help from you guys).
However, I guess I never learned the correct way to handle a user login. It seemed to me that I could just test the user-entered credentials against those stored in a database, then set a session variable containg that user's record number. Then, not only would I have an easy way of knowing who this user was and therefore what info to serve him, but I could test for the existence of a valid login on every page in the protected folder, by adding this code to my application.cfc in that folder:
<cfset This.Sessionmanagement=true>
<cfset This.Sessiontimeout="#createtimespan(0,8,0,0)#">
   <cfif NOT isDefined ("session.username") or NOT isDefined ("session.password") or NOT isDefined ("session.storeID")>
     <cflocation url="../index.cfm" addtoken="no">
   </cfif>
...and it goes on to run a query and verify that the session.username and session.password match for the store defined by session.storeID. If not, all session variables are cleared and it bounces you back to the login page. When the user clicks Logout, all I do is delete all the session variables.
This seemed to work great for like a year, but lately I've been getting reports that the login doesn't seem to persist for longer than approx. 20 minutes of inactivity. You can see I specified session variables to remain active for 8 hours (I know that seems like a drastically long login, but it's what's necessary for this application). I've only gotten this report from a few people, and I myself can't seem to duplicate it... I've tested an inactive login for 45 minutes now and it held.
SO: any reason you can think of why session variables would be spontaneously clearing for some people? Would having your router reset its IP address invalidate the session or something? Also, the problem seemed to begin appearing after my host upgraded all their servers to CF9... could there be any relation?
And on a more general note... did I go about this completely the wrong way to begin with? If so, what's the standard way to manage a login?
Lots of questions, I know... thanks very much for any answers or suggestions!
Joe

Ian,
Thanks very much - very helpful information.
Sounds like passing the tokens in every request is probably the way to go for this. I don't think it's likely that any users will be sharing links, unless they actually intend for the recipient to see their info anyway.
Is that all I would have to do, is add the tokens to every path? Would that guarantee that all the session variables would remain valid until timeout or being cleared?
Again, thanks, you've been really helpful.
Joe

Unfortunately this is the nature of HTTP web applications. There is NO state maintained from HTTP request to request. This is by design in the HTTP protocol specifications.
ColdFusion provides two methods to circumvent this limitation. Each method has limitations and caveats. They both rely on the passing of tokens between the client and the server with every request. These tokens can be passed as cookies OR URL (GET) variables. You are using the cookie method, which is the simpler and most common. You may be experiencing the limitation of this method. If something happens to the cookies the session can be lost.
You could pass the (CFID & CFTOKEN) OR JESSIONID tokens through the URL query string with every request. This requires one to add these values to every link, form action, cflocation or other request path in our application. ColdFusion provides the session.urltoken variable to make this easier to do. The tokens will be visible to the user. Also if the links with an individual token is share with other users, via e-mail, chat, social networks, etc and one of these users utilize the link during the life of a session (8 hours apparently in your case). Then that user will access the session of the original user.
Cookie session management is by far the most common choice by CF developers. If these methods do not meet your needs you would need to go beyond the HTTP limitations of web applications. One might be able to accomplish this with a Flex|Air|Flash applications that can be configured to use a continuous connection to the server. Thus not suffer the stateless nature of the normal HTTP request-response cycle.
I do not know if a router resetting would cause cookies to be discarded or otherwise invalidated. But I would not think it is beyond the relm of possibilities.

Session variable causing ADODB.Field error '800a0bcd'

i have a page that before the session variable was added,

How to default bind variable using session variable at run time

Hi All,
I have a requirement where all VO queries (multiple VOs) produce only records that meet a certain value.
For example, I have three tables with 3 VOs and each of them has a one-to-many relationship to another table (let's call it ref table and this table has a field called release). One of the 3 VOs is a parent/master table, and the other two are child tables. I created a VO for master table that linked to the ref table and created a view criteria using the release (use bind variable) field from the ref table. The other child tables have their own VO that has view criteria that also linked to ref table using the release field.
On the UI page, I created a query component and a table from the master table VO. I also dropped the child table VOs in a tabbed panel which partial triggered by the master table. When I ran a query for a 'release' (hint: ref table value), the table for master table was filled the correct records that meet the criteria. Unfortunately, the child tables were not correct due to the query didn't use the bind variable that filter only records for the same 'release' value as the master table.
The question is how do I 'default' or dynamically set the bind variable on the child tables based on the selection criteria from the query component. I am thinking to set a session variable from the query and use it in the bind variable in the child table, but not sure how to do it.
Any suggestion how to do it or better solution to achieve the same effect?

Hi,
How about creating a custom AMImpl method, that takes parameters as required, and set the bind variables for all the desired VOs and perform executeQuery on them.
You could expose this as client interface, and then use the method as parameter form.
Check this thread for ex.

Issue with session variable

Hi,
I'm trying to setup a session variable to filter an Answer query based on the user login name. I've created the following
- A database table that contains a user name and its related filter (Entity)
- An initialization block for the session variable to issue the following sql: select Entity from table where user_name = ':USER'
- Created a target session variable called CURR_ENTITY as the target and assign a default value as 'No entity'.
- Filter my Answer query to use the session variable CURR_ENTITY
After restart of BI server and Presentation services and opening the report, CURR_ENTITY is always set to the default value. I've checked NQQuery,.log and looks like the initialization block was not returning any rows.
Any ideas on how to get around this issue? Thanks.
Regards,
Gerd

Hi gerd,
select Entity from table where user_name = ':USER'Check if this query is returning values in the backend DB.If so it is returning then it should work fine in session variable.
After defining the target variable CURR_ENTITY and test it in the screen.That shows you is it picking all the values or a single defaulted value.
If its showing all values then re-check your block once again.
(OR)
In the target variable instead of variable define row-wise initialization (i mean check it) and change the SQL in the variable to this
select 'CURR_ENTITY',Entity from table where user_name = ':USER'
and test it so you can use it in answers .....it should work with what is required.
hope answered the question.
Cheers,

Row level security with session variables, not a best practice?

Hello,
We are about to implement row level security in our BI project using OBIEE, and the solution we found most convenient for our requirement was to use session variables with initalization blocks.
The problem is that this method is listed as a "non best practice" in the Oracle documentation.
Alternative Security Administration Options - 11g Release 1 (11.1.1)
(This appendix describes alternative security administration options included for backward compatibility with upgraded systems and are not considered a best practice.)
Managing Session Variables
System session variables obtain their values from initialization blocks and are used to authenticate Oracle Business Intelligence users against external sources such as LDAP servers or database tables. Every active BI Server session generates session variables and initializes them. Each session variable instance can be initialized to a different value. For more information about how session variable and initialization blocks are used by Oracle Business Intelligence, see "Using Variables in the Oracle BI Repository" in Oracle Fusion Middleware Metadata Repository Builder's Guide for Oracle Business Intelligence Enterprise Edition.
How confusing... what is the best practice then?
Thank you for your help.
Joao Moreira

authenticating / authorizing part is take care by weblogic and then USER variable initialized and you may use it for any initblocks for security.
Init block for authenticating / authorizing and session variables are different, i guess you are mixing both.

Clearing custom session variable in 5.0

I have set a custom session variable in a method called in the OnAfterLogin PEI.
Do I need to ckear this session variable on logout? If so, how do I do that?
Or does the session variable clear on its own if teh session is abandoned or killed on logout?
I just want to make sure I am not leaking any memory and do proper housekeeping.
Thanks!
Vanita
Staples

Sam,
It appears that you are one of the few installations that actually used a display/formatting page under 4.x. Under 5.0 you have the option of going directly to the source of the card or gatewaying the card. Those are your only two options to my knowledge. I suppose that the answer might rest on using docfetch but this would require a custom CWS.
Good Luck

Using row-wise multi-value GROUP system session variable in report filter

The title says it all except I am using 10g OBIEE.
What I want to do is filter on the dynamic system session variable GROUP created in a row-wise initialization block.
The GROUP vriable is being set up correctly and it shows the user dynamically put into the correct groups in Answers.
(Using the admin tool and looking at the user session, only the initial authentication block variables show up.)
But if I want to filter using the value of GROUP it doesn't work.
The obvious way is to choose the filter icon, then choose Add -> Variable -> Session, enter GROUP, and then display results.
It comes back with no rows.
Any idea how to do this? I've tried lots of things but none of them work either producing no rows or an error.
This is the kind of Answers SQL this report is resulting in, which makes sense to me, but produces no rows.
SELECT "Package Virtual Group (Dim)"."Package Virtual Group" saw_0, "Contact (Fact)"."Contacts All Count" saw_1 FROM "Case/Transaction/ABC" WHERE "Package Virtual Group (Dim)"."Package Virtual Group" = VALUEOF(NQ_SESSION."GROUP") ORDER BY saw_0

Errors come from trying things that don't work.
For example, instead of =, using IN VALUEOF(NQ_SESSION.GROUP) or @{session.GROUP} or lots of other things.
The question is this:
how can I filter a column in Answers using the GROUP session variable which had been initialized in a row-wise initialization block?
I can find no way to do it. Mostly it returns no rows.Hi,
we had a similar requirement, where we have an external name that has project number values. We used row wise initialization to capture all the projects that a user belongs to. Then, we applied the filters at the RPD level, instead of doing it at the report level. From you requirement I see that you are trying to filter the groups based on user login. When a user logs in, he will see the information about the groups that he only belongs to. Correct me if I am wrong here.
Assuming I am right about your requirement, providing the filter that you need apply in RPD.
On all the fact tables are joined to the Package Virtual Group dimension, apply the below filter.
case when 1=1 then (Dim)"."Package Virtual Group" END = VALUEOF(NQ_SESSION."GROUP");
The reason for use of case statement here is, it converts the logical sql to IN Clause, helping us acheive the exact query that we would want.
Please Award points if this helps.
Thanks,

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

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().
