Servlet session managment

Hi
I am trying to set object in session
first I set object in session in first servlet as session.setAttribute("name"object);
this session obj can retrive in jsp page
I make one link <a href="abc which call another servlet
I want this session object can retrive in that servlet but this get null
How yo solve this problem

Are both the servlets in the same web app?
Your session cannot be accessed across multiple webapps

  • Session management in servlet

    Hi,
    I am using OC4J Server.
    I know the session in servlet can be managed with cookies. In addition, the session can be managed in HTTP session of OC4J. And How about the URL rewriting? Does it mean there are 3 methods to keep track of the servlet session. What are the difference of them. I am quite confused.
    Thanks in advance

    I see. Thanks.
    So it means there are two kinds of cookies, permanent cookies and session cookies.
    session cookies are used to store the session information.
    I have another question. I want to write a permanent cookies to the browser and get it again even if the browser is closed.
    The source code is like:
    Cookie cookie = new Cookie(cookieName, cookieValue);
    response.addCookie(cookie);
    Then I try to write some cookies in the browser, close the browser and open the browser again and I try to retreive the cookies using the following codes but the cookies disappear.
    Cookie[] cookies = request.getCookies()
    if (cookies != null && cookies.length > 0) {
    for (int i = 0; i < cookies.length; i++) {
    Cookie cookie = cookies;
    Is this the correct way to store and retrieve permanent cookies?
    thanks in advance

  • Session Manager not thread safe

    We are running 6.0 web server with IWSSessionManager turned on. We have the failover set to true so that we always load from the persistent store.
    We had a situation where a frame set invoked 2 requests to the application. The logic in the session manager seems to be for each request:
    1) the session is loaded from the database.
    2) the new session overwrites the session in memory.
    3) the servlet/jsp uses that session.
    4) that session is persisted.
    Now.. if only one of the requests actually modifies the session then threadA and threadB have 2 session instances which have unique objects with the same session id. The last one to complete is stored in the database. This would result in data loss. (btw.. the code in question is IWSSessionManager.getSession(String id, ServletContext context)).
    Has anyone else seen this, or have we set up something really wacky?
    Thanks!

  • Plugin based Web Service with session management

    I am trying to make a web service in java with jax-ws that should support extensions to the service without rebuilding the project. I thought it might be possible to make a standard web service and the let each plugin create their own service, making the client side plugin point to both the standard service and the plugin specific one. This way I could have user management and such in the standard service and the more plugin specific one in an other service. The problem is though, how do I make a common session for all the services? All services are running at the same server and on the same domain name.
    I checked the HTTP headers and found out that the JSESSIONID was changing when I created a new port on the client side. I was trying to implement a SOAPHandler to edit the cookie in the HTTP header, hoping that this will lead to the same session across the services. But found it hard. It was no problem reading the "Set-cookie" header, setting the cookie on the new requests was harder, as the CookieJar object seems to be internal [1]. And the MessageContext.HTTP_REQUEST_HEADERS wasn't created at the time my handlers run. Is there an easy solution to this?
    I am not sure if my idea is a good solution to the main problem, and all other ideas are more than welcome. I hope it is possible to extend the features of my server without rebuilding the project. If anything is unclear, feel free to ask :)

    Could you explain plug in scenario with one example?Ok. We have not chosen exactly how to do this, but the idea is that someone may be able to extend the functionality of our server without rebuilding the project. We thought of something like a jar file with a implementation of some abstract classes. It should at least only be necessary to redeploy the project into the web container. The problem is; how do we let the plugins extend our web interface? One solution we thought of was to let each plugin have it's own service and dynamicly link to the plugin services from the main service that we provide as standard in our server. This way we may have some kind of plugin support on the clients as well, making the client side plugins know what kind of service it needs on the server side and thus extending the functionality all together.
    Hope that explains our scenario. Feel free to comment and add new ideas :)
    Regarding session management, its not advisable to manage the session in web services since that way it will become non interoperable.The documentation we found regarding sessions and jax-ws was all doing sessions with HTTPSessions, and to let the web container handle that.
    On the server side
        @Resource
        private WebServiceContext wsContext;
        private HttpSession getSession() {
            MessageContext mc = wsContext.getMessageContext();
            return ((javax.servlet.http.HttpServletRequest)mc.get(MessageContext.SERVLET_REQUEST)).getSession();
        HttpSession session = getSession();
        session.setAttribute("User", user);On the client side
    ((BindingProvider)port).getRequestContext().put(BindingProvider.SESSION_MAINTAIN_PROPERTY,true);Do you have other standard options for us on how to do session management? All ideas are more than welcome

  • Setting secure on session management cookie only in production

    I am faced with the following:
    In our developmentcycle we deliver full application exports to an acceptation environment and after testing to a production environment.
    However, only our production site does HTTPS. Development and acceptation only do HTTP.
    In production we have to set the "secure"flag on the session management cookie.
    We would like to set this flag in our deployment scripts.
    So,
    Is there an API we could use to set the "Secure" flag in the APEX metadata using SQL*Plus?

    hi
    ->Use request.getParameter(String s) to recieve the infomation from the html page into your servlet.for storing session specific info go for
    session.setAttribute(vble,value;
    hope it'll solve your problem.

  • Session management question

    I have a requirement to prevent multiple sessions per user id. So, when a
    user logs in to our app, any existing sessions he has must be invalidated.
    Does anyone know the correct WebLogic API call to use to locate a session
    object for a given user id? I need to call this so that I can invalidate the
    existing session.
    Thanks,
    Rob.

    Hi Rob,
    Using Servlet 2.3 features this can be done using the sessionCreated and
    sessionDestroyed API (chapter 10 of the servlet 2.3 Spec). This Spec has been
    implemented in WLS 61.
    These methods are provided by the HttpSessionListener interface and they are
    called by the container whenever a session is created or destryed as their name
    suggests. These methods take in HttpSessionEvent as their parameter which can be
    use to get a handle of the corresponding Session object. Once you get this
    handle you can store it in a Hashtable with userID as the key.
    You can use this Hashtable to verify if the session for a particular user
    already exists or not. Once the session is invalidated, the sessionDestroyed
    method will be called and this allows you to remove the session handle from the
    Hashtable. The Hashtable thus, maintains a list of active sessions in an web
    application.
    A sample impl:
    public void sessionCreated(HttpSessionEvent evt){
    sess = evt.getSession();
    /* have code to populate the sesion Attributes */
    log("\nsession created " + sess.getId() );
    log("Session id: " + sess.getAttribute("userID") );
    synchronized(this) {
    h.put(sess.getAttribute("userID"), sess);
    public void sessionDestroyed(HttpSessionEvent evt){
    sess = evt.getSession();
    log("\nsession destroyed: " + sess.getId() );
    synchronized(this) {
    h.remove(sess.getAttribute("userID"));
    hope this helps,

    It's a pretty simple task - provided you expect no more than a few hundred

    Anyone got any tips about how to implement this in scalable manner?

  • State management and session management

    Hi
    Can anyone tell me a good way to maintain state without using EJB?
    and is there a way to manage sessions without cookies and URL rewriting.
    Thanks

    Can anyone tell me a good way to maintain state
    without using EJB?Of course. Depends on what sort of state you are looking to maintain... if you are looking for alternatives to stateless session beans, you can simply use the servlet session i.e., via HttpSession.set/getAttribute().
    and is there a way to manage sessions without cookies
    and URL rewriting.Not really, cookies and URL rewriting are the only reasonable solutions. I suppose one could design an alternative approach. The bottom line is http is a stateless protocol -- to maintain state across requests a session id must be associated with the client.

  • WebService with Session manager and Connection pooling

    I've created many a Oracle users in our RDBMS. It comes to this, that every
    user in our Company has its own oracle account.
    We are developing now a Web application (Internal information system) for my
    Company.
    This Web application will have GUI created in perl and middle tier will be
    Oracle WebServices.
    This WebServices will be connected to the DB for every oracle user and it also
    must have a session management.
    And this is a Action plan:
    1. the user will log to the Web GUI with his oracle login name and a password
    2. this oracle user name and the password will be sent from this Web app to the
    WebService
    3. this WebService will create a connection over a JDBC (not over DataSources)
    and will create also a session (maybe like a servlet)
    4. in this session the instance of the created connection for this user will be
    saved and the WebService will return to the Web app the session id
    5. and this session id will be then used for further calling of WebServices
    Then comes another user, signs up over the Web app with his oracle account and
    this whole process repeats.
    Finally every logged user will have its own session id with his own connection
    instance to DB.
    Maybe it's possible, that it will work only with Servlet (with HttpSession) and
    WebService created from this Servlet.

    Take a look at the Statefull Java Web Services. It may be able to handle your use case.
    http://download-west.oracle.com/docs/cd/B14099_04/web.1012/b14027/javaservices.htm#i1027664
    You should be able to cache the database connection, directly in your service implementation class.

    Such API is not provided since it would constitute a security

    thanks in advance

    Um,maybe the port that you use for transmission is already occupied.
    Make sure that you are not using JMStudio to transmit streams while trying to receive streams from the same port.

  • What is new with MAX 2.0 and is it compatible with Session Manager?

    We added non-IVI instrument information in, basically the same structure as for IVI instruments,
    into the ivi.ini file to keep all instrument information in the same place. Using MAX Version 1.1 caused no problems whatsoever and the system worked fine. With the advent of MAX 2.0 you seem to use ivi.ini as well as config.mxs to store instrument information. What we have found now is that given a working ivi.ini file from MAX 1.1, we end up with 2 or 3 copies of all the devices in the IVI Instruments->Devices section! When the duplicate entries are deleted and the application exited, the
    ivi.ini file is updated minus the [Hardware->] sections which contain the resource descriptors that our appl
    ications look for. As an added complication, under MAX 2.1 (From an evaluation of the Switch Executive) It behaves the same, except that it almost always crashes with one of the following errors. 'OLEChannelWnd Fatal Error', or 'Error#26 window.cpp line 10028 Labview Version 6.0.2' Once opened and closed MAX 2.1 will not open again! (Note we do not have LabVIEW on the system.) What is the relationship between the config.mxs and ivi.ini now? Also, your Session Manager application (for use with TestStand) extracts information from ivi.ini and may expect entries to be manually entered into ivi.ini (e.g. NISessionManager_Reset = True) i.e. Is the TestStand Session Manager compatible with MAX 2.0?

    Brian,
    The primary difference between MAX 1.1 and 2.x is that there is a new internal architecture. MAX 2.x synchronizes data between the config.mxs and the ivi.ini. The reason you're having trouble is that user-editing of the ivi.ini file is not supported with MAX 2.x.
    Some better solutions to accomplish what you want:
    1. Do as Mark Ireton suggested in his answer
    2. Use the IVI Run-Time Configuration functions. They will allow you to dynamically configure your Logical Names, Virtual Instruments, Instrument Drivers, and Devices. You can then use your own format for storing and retrieving that information, and use the relevant pieces for each execution. You can find information on these functions in the IVI CVI Help file located in Start >> National I
    nstruments >> IVI Driver Toolset folder. Go to the chapter on Run-time Initialization Configuration.
    I strongly suggest #2, because those functions will continue to be supported in the future, while other mechanisms may not be.

  • Session management problems with SSO

    Hi all-
    I've been getting an Apex app tied to SSO as a partner app (per http://www.oracle.com/technology/products/database/application_express/howtos/sso_partner_app.html). So far, it sort of works. If I go to my apex app, it redirects me to SSO, where I authenticate and end up back in the apex app. Great. Here are two problems I've run into:
    1. If I am already authenticated to SSO, and I go to my apex app (url like: http://host/pls/apex/f?p=101:1), my browser goes into an infinite redirect (url like: http://host/pls/apex/f?p=101:1:::::FSP_AFTER_LOGIN_URL:\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|\\\\\\\\\\\\\\\\\\\). To resolve, I have to clear cookies.
    2. If I am using my apex app, then log out of SSO (in another browser window), I can still click around in my apex app (i.e., apex thinks I'm still authenticated).
    Anyone have any thoughts? I'm wondering if I need to do something in page session management (under authentication schemes) to fix #2, but I have no clue about #1.
    Thanks
    Rob

    Hi Scott-
    Thanks for the info on #2 - I'll work on that after I get #1 sorted out, since it's the more dire problem. Here's some more info:
    Apex version = 3.0.1.00.08
    SSO SDK = ssosdk902.zip
    I set it up as "My Application as Partner App." I used "MY_PARTNER_NAME" as SSO Partner Application Name. In the list of SSO Partner Apps on the SSO Admin page, my partner app name is also MY_PARTNER_NAME. It gives the following info:
    Login URL:      https://sso_host/pls/orasso/orasso.wwsso_app_admin.ls_login
    Single Sign-Off URL:      https://sso_host/pls/orasso/orasso.wwsso_app_admin.ls_logout
    Home URL: http://apex_host/pls/apex
    Success URL: http://apex_host/pls/apex/RBLICK.YOUR_PACKAGE.PROCESS_SUCCESS
    Logout URL: http://apex_host/pls/apex
    RBLICK is the schema owning the apex app. In there, I created a package called YOUR_PACKAGE:
    create package YOUR_PACKAGE as
    procedure process_success(urlc in varchar2);
    end YOUR_PACKAGE;
    CREATE PACKAGE BODY YOUR_PACKAGE AS
    procedure process_success(urlc in varchar2) as
    begin
    wwv_flow_custom_auth_sso.process_success(
    urlc=>urlc,
    p_partner_app_name=>'MY_PARTNER_NAME');
    end process_success;
    END YOUR_PACKAGE;
    Anything look obviously wrong to you?
    Thanks!
