Getting http session attributes

Hello,
Perhaps the question here may sound stupid, but I have real problem with that:
Is it possible to obtain http session attributes from the client side
(and even worse) in other languages like VB or VC++? What i mean is that after creating Http session by servlet, and setting some attributes, is it possible to get them by VC or VB app? Thanks in advance :)

What i mean is that after creating Http session by servlet, and >setting some attributes, is it possible to get them by VC or VB app? >Thanks in advance :) What do you mean by "VC or VB app" ?
A desktop app written in VC or VB ? a web app in VBscript/ASP ? (but as far as I know there is no web language based on VC, unless you're talking about executable CGIs that can be written in any language).
Assuming that you talk about VB-ASP, I don't think it possible "out of the box" to retrieve session variables created by a servlet in an ASP page.
That would be possible if HTTP supported sessions.
Sessions are implemented at the application level on top of HTTP; they reside in the application that handles requests. Outside it, they don't exist.
It doesn't mean that you can't do that, but that you have to do that using HTTP constructs like URL rewriting or form submission.
For example you could set session variables in a JSP page, and then forward the request to an ASP page through a GET request with all session variables written in the URL.

You can, but that's not a best practice.
Re: How to reach HttpContext from model Project

How can I flag HTTP session attributes to not be replicated ?

          WLS 5.1 SP8 - In memory replication of a stateful servlet. Is
          there any way to flag data that has been, or is being, loaded into
          a HTTP session so as to not be replicated ? It's a long story,
          but we have some data loaded into a hashtable, more specifically
          a Properties object, stored in our session. With the hastable
          already loaded into the HTTP session, weblogic does not detect
          when we add values to the table, and therefore does not replicate
          the changes. Which is ok since WLS is working as designed. To
          get around this we load the hashtable back into the session everytime
          we add a value to the hashtable. Yup, I know that's ugly. Anyway,
          what I'm trying to find out if is there is an attribute that we
          can set to indicate, to not replicate this data or that data.
          Something along the lines of a attribute on a per hastable value
          basis. For example, I load value A into my hashtable, then I
          need to put my hashtable into the session to get it replicated.
          Next I load value B into the hastable, and again to get it replicated
          I have to load the entire hashtable back into the session. The
          problem here is that the entire table gets replciated. Does anyone
          know if I can set an attribute on value A, when I'm adding value
          B, so as to not replicate value A when I reload the table ? Of
          course all goal is to not store so much data in the session, but
          I'm trying to find a work around until that is completed.
          Thanks,
          David


          Where can I find documentation on the details of how Weblogic decides what will
          be replicated in the HTTPSession object (for example, it only replicates attributes
          which are set or updated using "setAttribute()"?

Getting a session-attribute

Hi
I have managed to store a session-attribute containing user-info:
HttpSession session = request.getSession();
session.setAttribute(Constants.USER_KEY, user);
when the current user gets to the mainmenu I want to show different content depending the users authority, problem :
How do I in my menubean (extending org.apache.struts.action.ActionForm)
retrieve this users sessionvalues ?
I can get the servlet but I can't figure out how to get hold of the session
thanks in advance

Hi,
Set you session variable like this and put it in a session for you to read it at a later stage:
HttpSession session = request.getSession();
session.setAttribute("USER_KEY", user);
Read it from you jsp/servlet/bean like:
HttpSession session = request.getSession();
String usr_key = (String)session.getAttribute("USER_KEY");

Define HTTP Session Attribute in a Custom Authenticator

Hello everyone I developed sucessefully a Custom Authenticator for WLS10 that interacts with a web service.
But now I need to provide an object to the web applications with the some user information.
I was wondering defining the object in the HTTP Session but I dont know how to do it via de LoginModule of the custom authenticator.
Can anyone provide me some tips?
thanks in advance.

What kind of user information do you need to pass on to the webapplication ? username can be retrieved by request.getRemoteUser() (after successful login).
May be you need to clarify little bit more on what you want to achieve.

HTTP Session replication problem

Hi all,
After 3 days trying to make the http session replication work in my cluster is time to ask some help.
I´m trying to make a simple application (only a servlet) simulate a http session replication.

Weblogic.XML descriptor

               <param-value>replicated</param-value>
          </session-param>
</session-descriptor>
CODE of the Servlet
HttpSession session = request.getSession();
          String sessionIdentif = (String)session.getAttribute("SESSIONIDENTIF");
          boolean boolNewSession = true;
          if(sessionIdentif == null) {
               session.setAttribute("SESSIONIDENTIF", "1234567890");
          } else
               boolNewSession = false;
As you can see the object that i put in session is a String, so Serializable....
All the requirements are validated (i think...) but it still not working ... i get the SESSION ID : WvHQMKzBh9T35BPhGJxyhQtGks5Q3qJmxnJwGn8mn7V24FM92cnh!949557342! NONE !1284141857480
And the NONE said that the session isn´t replicated.
Any idea what´s wrong with my try of getting http session replication working??
cheers,

Hi,
Thanks for your help.
I´ve tried your application with your proxy application but still no work...
I´m getting :

In my early post i forgot to mention that i´m using an Apache 2.2 in the front-end with Weblogic 9.2 (cluster).
What is happening in this weblogic configuration so that this session replication don´t work.

How to get from data entered on a form to a session attribute

I have a jsp with a form with fields that are updated by the user.
The values are in the fields value as I expected.
Example. document.frm.Name.value = "Me"
How do I populate a session variable with document.frm.Name.value?
I think I have to do a request.getParameter("Name") followed by a
session.SetAttribute. But the request.getParameter does not get populated with the latest value in document.frm.Name.value.
Any idea is welcomed. Thanks

bug fix for watson 2887837 Not getting duplicate session detected error when same flex client id is used from two different HTTP sessions in CRX.
get the sessions id before we invalidate the duplicate session.

For our profect I think this issue was caused as follows:
Believing that remoting was full asynchronous we fired a 2 or 3 remote calls to the server at the same time ( within the same function ) - usually when the users goes to a new section of the app.
This seemed to trigger the duplicate http session error since according to http://blogs.adobe.com/lin/2011/05/duplication-session-error.html two remote calls arriving before a session is created will cause 2 sessions to be created.
Our current solution ( too early to say it works ) is to daisy chain the multiple calls together .
Also there seemed to be an issue where mobile apps that never quit ( thanks Apple! ) caused the error when activated after a few hours.
I guess the session expires on the server and the error above occurs on activation.
So the mobile apps now ping the server with a remote call when activated after sleeping for more than one hour.
All duplicate http errors are silently caught and reported.
Fingers crossed we won't get any more!

Get Http Request in Session Listener?

Is it possible get Http Request in Session Listener when session is created? I need to get cookies when session is created.
anyone knows?

No, it is not possible.

URGET!!! Get Session Attribute On Form

Hi alls,
I develope application with Forms 9i and JSP.My Application Program is developed by Forms 9i but Menu,that call application program,is developed by JSP.I knew that if I want to call a Form from JSP,I have to append &otherparams on URL.
My Problems is :
1.I want to get some parameters,is seted to session attribute in JSP,from Menu to Forms and don't let the users to see these parameters on URL. HOW CAN I DO? (URGENT!!!!)
2.If I want the Menu always display on top and application display on botton of browser. HOW CAN I DO?
Thank you for advance.
PS. Menu develop in dropdown style,it will expand(drop) when move mouse on it.

Hi,
1.I want to get some parameters,is seted to session attribute in JSP,from Menu to Forms and don't let the users to see these parameters on URL. HOW CAN I DO? (URGENT!!!!)
You can't get session attribute from Forms because it runs as an Applet in the browser and does not have access to the server side request object.
You can access request parameters that are used to call Forms, but that's it.
2.If I want the Menu always display on top and application display on botton of browser. HOW CAN I DO?
Use HTML frames

Error in retrieving session attribute for ejb remote in clustered env

          We store EJB remote object in session and differnt clients retrieve it from sessionbefore
          making a business method call. This seems to work in most cases but sometimes
          it gives the exception attached. This happens only in a clustered environment.What
          has been observed is that if we put the remote object inside a hashtablewhich
          in-turn is stored in session retrieval from hashtable does not give thisproblem.
          Any suggestion / solution would be greatly appreciated.
          Regards,
          Shilpa

          The EJB is stateful session EJB. Have seen some posts pointing to problems
          with
          stateful session EJB and cluster and the suggested solution was SP4 (we are
          on 6.1 SP3).
          Hope this gets more clarity (and some solutions!!!).

URGENT http session HELP PLEASE

Hello all.
i work in http session...after i redirect in https(login.jsp for example)
in JavaBean for Login.jsp try get connection with all object or JavaBeans from last http session ...but i cannot do it.
Where my problem ?
How i can have access across sessions?
Help me please.

i don't understand your meaning exactly,but i think what you mean is maybe to make a bean accessible across the session?is that right?if yes,you can set the scope attribute to session,such as:
<jsp:useBean id="..." scope="session" class="...."/>

I am not sure if this solved the problem.
But now, I am using Sun One Web Server 6.1 sp1.
You can download it from
http://wwws.sun.com/software/download/products/4000635d.html
Try using this and see if the problem gets resolved.
