Listener Servlet storing session variables

hi all,
i have a listener servlet class which is performing tcp/ip socket communication. now i want this class to store session variables. i have tried to implement it and access the stored variable values from other pages, but i am unable to access them, which tells me that the servlet is not storing the values in the first place.
any help. thanks in advance.

can you post some code.
it is also posible that those values are stored in a different session that in the one you try to read from

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.

Storing session variables

Any way to effectively bring 3 different column values into a session upon login and store them as variables or application items for later use for auto populating fields? Also, these values need to be session related, and there may be more than 10 sessions at one time, meaning up to 30 values, 3 x 10 users.
Thanx
Jacob

OK, got application items set. I still have another question about choosing one of two item values. The information I pulled into application items was like the following: Emp No, Unit Assigned, Unit Detailed. The question is, everyone has a value in column Unit Assigned, but not everyone has a value in Unit Detailed. I pulled both assigned and detailed into the application as I couldn't see how to pull one or the other based on null values. What I had wanted to do was set just one UNIT value based on whether or not there was data in the Unit Detailed column. Something like: if unit detailed is null, then unit assigned. Problem was I couldn't get the syntax into a computation using if then. My idea was to set a session value for each one then try to compare them while the page rendered with a similar formula but I still can't get the correct syntax.
How and where should the assigned vs. detailed formula be used? Should I create just one UNIT application item and fill it with an output from a formula or should I set both and choose either one somewhere in the page rendering?
i got halfway, this seems easy I just can't get the if then portion going.

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?

Session variable not storing in custom trigger

I have a custom trigger in which I want to store a session variable , so i can use the value in the insert transaction which happens after. But for some reason the session variable is not stored, resulting in the data not being stored.
any clues would help.
rudi
here are the relevant code:
//start Trigger_Custom_Subject_Mentor trigger
function Trigger_Custom_Subject_Mentor(&$tNG) {
//Check subject exists
@session_start();
$_SESSION['sb_id'] = $subject_id;
//end Trigger_Custom_Subject_Mentor trigger
// Make an insert transaction instance
$ins_share = new tNG_insert($conn_smart);
$tNGs->addTransaction($ins_share);
// Register triggers
$ins_share->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "KT_Insert1");
$ins_share->registerTrigger("END", "Trigger_Redirect", 90);
// Add columns
$ins_share->setTable("`share`");
$ins_share->addColumn("share_item", "NUMERIC_TYPE", "POST", "share_item");
$ins_share->addColumn("share_subject", "NUMERIC_TYPE", "SESSION", "sb_id");

hi User,
1) Pull a dummy column in Fx use the Session variable --->(Variable -->session )
2) Next, goto narrative view in Narrative view section use @1
3) If u want you can hide the column that we created in criteria section

How to use session variable in JSP function & How to use both JSP Servlet

Hi,
I am new to JSP and servlets
Still I am devloping a website in JSP. I am not mixing JSP with servlets, but I do create Java files for bean, logic and database works.
I try to keep the hard coding part out of JSP.
I dont how to use both JSP and Servlets in combination.
Hence If needed I write some functions in JSP.
but it gives me error
+<%! public void abc()+
+{+
int intUserId = Integer.valueOf((Integer) session.getAttribute("MySession_UserID"));
+}+

Saying cannot find symbol session
1) So can u please tell how can I access session variables within JSP function
2) And also give me some links/tutorials about useing both JSP and Servlets in combination.

Session variables dropping

I've been having this problem for a long time so I thought
I'd post again and maybe get a hit this time.
We run off windows cfmx 7.x now fully patched, prior to that
we were on cfmx 6.x. We use session management only. Many times on
a new page hit the user loses about half of their session variables
up to all of them. Typically we have them test on the same machine
using different browsers. 99% of the time switching from IE to
firefox solves the problem, most of the users have had IE 6.x.
I experienced this problem myself for about 4 months time and
I could reproduce it daily when neccessary by simply opening a new
window to our application and the session information would persist
to the new window but the parent window would receive a new cfid
and lose all session information. New windows aren't the only
issue, we see a lot of lost session variables in one click, same
window, functionality. I've had hooks in place to test if the
domain was different on page hits removing the www or something but
so far have not found anything there. Each time a new CFID is being
issued and they are losing the original. We attempted to put CFID's
in the URL at all times but that leads to other issues and didn't
solve the problem for us anyhow.
This has been a serious issue for awhile and browsing these
forums I see others are experiencing it to some extent too. I'm
wondiner if anyone has any tips or can confirm the CF Admin/app.cfc
setup you use if you're not seeing any problems like this.

right... response.sendRedirect(). sendRedirect works by sending a repsonse to the browser with a location header. The browser sees that header and makes a new, separate request to the new location. It's no different then typing the location in the location bar in the browser or clicking a link.
But that doesn't matter. If you have 2 web applications (aka 2 servlet contexts) on the server, they are not going to share sessions between them. So the first page is working off one session in one context with some ID. Then the redirect sends it to another page in a different context. That session ID is not valid in that 2nd context, so a new session is created like it was a first time user. And if you redirect back, you may not get the same session for the first context, unless the session ID cookie defines the path as well (I'm not sure offhand).
The "application" object is the servlet context, specifically a javax.servlet.ServletContext object (or implementation of the interface, technically). Nothing is shared between contexts.
Now, you can always share things in one way or another. Store things in a database or in files. Use a messaging system like SOAP or JMS. Maybe the server allows for contexts to access each other (they aren't shared in that case, just that you can get a named context and read what's stored in it).
Or don't have your separate contexts, use subdirectories in the same context.

Problem storing sessions

My system is set up to redirect based on the group stored in
the database. My problem is that my code is not retrieving the
group and storing it as a session. Here is my code:
include("config.php");
session_start();
$connection = @mysql_connect($server, $dbusername,
$dbpassword)
or die(mysql_error());
$db = @mysql_select_db($db_name,$connection)
or die(mysql_error());
$sql = "SELECT * FROM $table_users WHERE usr_username =
'$username' and usr_password = md5('$password')";
$result = @mysql_query($sql, $connection) or
die(mysql_error());
//get the number of rows in the result set
$num = mysql_num_rows($result);
//set session variables if there is a match
if ($num != 0)
while ($sql = mysql_fetch_object($result))
$_SESSION[usrid] = $sql -> usr_id;
$_SESSION[name] = $sql -> usr_name;
$_SESSION[username] = $sql -> usr_username;
$_SESSION[password] = $sql -> usr_password;
$_SESSION[email] = $sql -> usr_email;
$_SESSION[verified] = $sql -> usr_verified;
$_SESSION[datereg] = $sql -> usr_date;
$_SESSION[phone] = $sql -> usr_phone;
$_SESSION[cell] = $sql -> usr_cell;
$_SESSION[fax] = $sql -> usr_fax;
$_SESSION[group] = $sql -> usr_group;
$_SESSION[squestion] = $sql -> usr_squestion;
$_SESSION[sanswer] = $sql -> usr_sanswer;
$_SESSION[company] = $sql -> usr_company;
$_SESSION[member] = $sql -> usr_member;
}else{
header("location:../no_acess.php");
if($_SESSION[group] == "admin"){
$_SESSION[redirect] = "admin/index.php";
}else{
$group = $_SESSION[group];
$_SESSION[redirect] = "lindex.php";
header("location:$_SESSION[redirect]");
exit;

I'm thinking that you are using URL re-writing for session management. This is the method where the session id must be written in the URL string of every request. This is probably where your problem lies. To start you should wrap the value you are passing to the sendRedirect() method in a call to response.encodeURL() to ensure the URL maintains the session id. Also any Javascript code that uses URLs should also use the response.encodeURL() method to encode the URL strings.
For instance, this is what you should do. In your code find the line that says "sendRedirect(someValue);" and change it to "sendRedirect(response.encodeURL(someValue))". If the Javascript is defined in a static HTML file or a .js file change this file to a JSP and make sure the value passed to the open() function is wrappered in a call to response.encodeURL().
To further explain what I think the problem may be, you have to understand session management as it is implemented in JSPs/servlets. There are various tutorials on this site that will explain it in detail.

Avoiding a session variable

Hi guys. I have the following problem. I have kind of a search engine that uses a servlet and normal java classes. When the user searches for something I get a list of objects. Thanks, when he follows a link I perfom an action on one of this objects.
At the moment I store the object list as a session variable which means that they will be moving back and forth (from server to client) all the time. These objects contain a lot of information so I want to avoid that, by keeping them in the server. Is there any way to do that?
Thanks

At the moment I store the object list as a session
variable which means that they will be moving back
and forth (from server to client) all the time.All the Objects are always stored in memory on the server, they never get sent back and forth between the server and the client. The server maintains the session with the client by using something like cookies or rewriting URLs.

J2EE session variables & Non Random Session IDs

Our server keeps failing our PCI compliance test due to the Session ID's being non random.
Description: Web Server Uses Non Random Session IDs Synopsis: The remote web server generates predictable session IDs. Impact: The remote web server generates a session ID for each connection. A session ID is typically used to keep track of the actions of a user while he visits a web site. The remote server generates non-random session IDs. An attacker might use this flaw to guess the session IDs of other users and therefore steal their session. See also : http://pdos.csail.mit.edu/cookies/seq_sessionid.html Data Received: Sending several requests gives us the following session IDs : CFID=896744 CFID=896745 CFID=896746 CFID=896747 CFID=896748 Resolution: Configure the remote site and CGIs so as to use random session IDs. Risk Factor: Medium/ CVSS2 Base Score: 6.4 AV:N/AC:L/Au:N/C:P/I:P/A:N
We are using J2EE session variables which I though was the more secure option. Is there something else you have to do to guarentee that the Session ID's are non random or is this the Compliance test picking up on a false positive?
P.S. It's a recent migration to CF10, don't know if that has anything to do with it.

Personally, I use the client scope instead of the session scope so that I don't have to worry about sticky sessions. That has always worked out nicely for me.
I read that article you referenced, and it's got some interesting stuff. In particular, I have seen the client scope database tables not purge as they're supposed to. And the stuff about preparing, executing, and then unpreparing SQL statements on each request is alarming, if true.
However, I have to say that I have never, ever, ever, ever had performance issues due to client variables. Not once. Whatever performance hit my application may incur from using client variables has, to this point, been completely dwarfed by the performance of the application itself. And, c'mon, the stuff about being lazy because you don't want to spend precious engineering time worrying about something like session management (which is never going to add value to your product) rather than coding something actually useful to your end users...that seems overly harsh to me.
I completely agree that storing client vars in the Windows Registry is bananas, as is the defualt 90 day purge limit (though as of CF 9.0.whatever, the default is 1 day, 7 hours, so clearly they've made some changes since this article was written). But I'm loathe to throw away client-based management.
I think, getting back to the issue at hand, that this may be a false positive. CFID is sequential, but CFTOKEN is not; that should really be the end of the story. I'll see if McAfee will listen. (-;

How to retrieve sessions variables in JSP

hi,
I am trying to retrieve session variable from servlet to JSP.
In the servlet i am retrieving employeenames from database and storing them in a ArrayList variable then i am setting this variable into the session.
When retrieving the session in the jsp it displays as [empname1, empname2].
Please help how to retrieve them
Thanks in Advance,
sha

At the servlet:
ArrayList<String> employeeNames = new ArrayList<String>();
employeenames.add(blahBlahblah);
session.setAttribute("eNames", employeeNames);
At the JSP:
ArrayList<String> names = (ArrayList<String>) session.getAttribute("eNames");
for (String nom : names) {
do something with the name stored in String variable nom...
}

Session variable size limitation (LV Webservices)

Hi community,
I read couple dozen email addresses from an XML and trying to write them into a session variable. The email addresses are comma separated and have a total string length of about 1100 characters. When I try to write it into a session variable LabVIEW drops an error message (-67158).
It is very clearly related to the size of the string as if use lets say only 200 characters I dont receive the error message.
How can I get rid of this limitation?
Thanks!

I am writing a general purpose webpage where I need email notifications. I have the workaround ready (before I send out the emails I dont read the emails from a session, but using the userID stored in the session to read the email from the xml). But generally having this limitation is annoying and unnecessary as normally you easily can store 100kB in one session. (probably even more, but that was the max I have ever did)

Trying to move a list of form variables to session variables of the same name

I am trying to move a list of form variables to session variables of the same name and I am having a lot of trouble.
I have never had to post of this forum with a language question in all the 10 years I have been using ColdFusion. I was a qa Engineer @ Allaire/Macromedia back when it was going from one to the other. I have a pretty good grasp of the language.
I have software that runs off a list. The fieldnames are variable and stored off in an array. It's survey software that runs off a "meta file". In this example; I have the number of fields in the survey set to 12 in the "metafile". I have each field declared in that file in array Session.SurveyField[1] and the above loop works fine. I include this "metafile" at the start of the process.
I cfloop around a struct and it works wherever I have needed to use it; such as here - writing to the database for example;
<CFQUERY NAME="InsertRec" DATASOURCE="Survey">
INSERT into #variables.SurveyTableName#
(EntryTime
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
,#Session.SurveyField[arrayindex]#
</cfloop>

   VALUES
    ('#EntryTime#'
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thisname = "Session." & Session.SurveyField[arrayindex]>
,'#evaluate(variables.thisname)#'
</cfloop>

</CFQUERY>
NOW HERE'S THE PROBLEM: I am running into trouble when trying to move the form variables to session variables of the same name. It is the only part of the software that I still need the datanames hard coded and that is a roadblock for me.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thissessionfield = "Session." & Session.SurveyField[arrayindex]>
<cfset thisformfield = "Form." & Session.SurveyField[arrayindex]>
<cfset #thissessionfield# = #evaluate(thisformfield)#>
</cfloop>
I have tried it with or without the "evaluate"; same result. It doesn't give an error; it just ignores them (session variables look as such in the next page in the chain)
q01_name=
q02_acadtechorna=
q03_water=
q04_firstaid=
q05_cpr=
q06_lifeguard=
q07_aed=
q08_projadv=
q09_color=
q10_santaclaus=
q11_supervisor=
q12_supervisoropinion=
Note: they exist because I CFPARAM them in a loop like the above at the start of the procedure) - and this works just fine!
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset dataname = "Session." & Session.SurveyField[arrayindex]>
<cfparam name="#variables.dataname#" default="">
</cfloop>
</cflock>
I EVEN tried exploiting the Form.Fieldnames list using CFLoop over the list and the same sort of logic within and it still gives me nothing....
Here's the FORM.FIELDNAMES value
"Q01_NAME,Q02_ACADTECHORNA,Q03_WATER,Q04_FIRSTAID,Q05_CPR,Q06_LIFEGUARD,Q07_AED,Q08_PROJAD V,Q09_COLOR,
Q10_SANTACLAUS,Q11_SUPERVISOR,Q12_SUPERVISOROPINION"
Here's the logic; SAME RESULT - The session variables don't get set.
<cfoutput>
<cfloop list="#Form.FieldNames#" index="thisfield">

<cfscript>
thisSESSIONfield = "Session." & thisfield;
thisFORMfield = "Form." & thisfield;
#thisSESSIONfield# = #thisFORMfield#;
</cfscript>
</cfloop>
</cfoutput>
The CFPARAM in a loop with variable output name works just fine; so does the post (which I included above) as does the SQL Create, Param Form Variables, Param Session Variables, etc.
THIS even works for moving BLANK to each session variable, to zero them all out at the end of the process;
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
</cfscript>
<cfset #thissessionfield# = "">
</cfloop>
</cflock>
Expanding on that code, you would think this would work, but it doesn't;
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
thisformfield = "Form." & thislocalfield;
</cfscript>


<cfoutput>
<cfset #thissessionfield# = "#evaluate(thisformfield)#">
</cfoutput>
</cfloop>
And see that debug code in the middle? To add insult to injury... When I uncomment that it shows me this. So it certainly looks like this should work....
Session.q01_name = "Me"
Session.q02_AcadTechORNA = "N/A"
Session.q03_Water = "Yes (certificate expired)"
Session.q04_FirstAid = "Yes (certificate is current)"
Session.q05_CPR = "No"
Session.q06_LifeGuard = "Yes (certificate expired)"
Session.q07_AED = "Yes (certificate expired)"
Session.q08_ProjAdv = "Yes (certificate expired)"
Session.q09_Color = "Gray"
Session.q10_SantaClaus = "Yes"
Session.q11_Supervisor = "Da Boss"
Session.q12_SupervisorOpinion = "Not a bad thing"
There must be some simpler way to do this. This way won't work against all odds even though it seems so much like it should.
So I end up having to hardcode it; still looking for an automated way to set these #@%$*@!## session variables over the list from the form variables of the same @#@!$#%$%# name. Do I sound frustrated???
No matter what I do, if I don't HARDCODE like this;
<cfset Session.q01_name = Form.q01_name>
<cfset Session.q02_AcadTechORNA = Form.q02_AcadTechORNA>
<cfset Session.q03_Water = Form.q03_Water>
<cfset Session.q04_FirstAid = Form.q04_FirstAid>
<cfset Session.q05_CPR = Form.q05_CPR>
<cfset Session.q06_LifeGuard = Form.q06_LifeGuard>
<cfset Session.q07_AED = Form.q07_AED>
<cfset Session.q08_ProjAdv = Form.q08_ProjAdv>
<cfset Session.q09_Color = Form.q09_Color>
<cfset Session.q10_SantaClaus = Form.q10_SantaClaus>
<cfset Session.q11_Supervisor = Form.q11_Supervisor>
<cfset Session.q12_SupervisorOpinion = Form.q12_SupervisorOpinion>
I always get this from my next page because the session variables are empty;

I tried duplicate as well, but I can not get the above to work...
Can anyone help me do this thing that one would think is simple????

I think if you use structure array syntax you should get the results you want.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
      <cfset session[Session.SurveyField[arrayindex]] = Form[Session.SurveyField[arrayindex]]>
</cfloop>
Or probably even easier.
<cfset session = duplicate(form)>
