Howto call the @Remove method of a stateful session bean after JSF page ...

I use EJB3, JPA, JSF in my web application. There are 2 database tables: Teacher and Student. A teacher can have many (or none) students and a student can have at most 1 teacher.
I have a JSF page to print the teacher info and all his students' info. I don't want to load the students' info eagerly because there's another JSF page I need to display the teacher info only. So I have a stateful session bean to retrieve the teacher info and all his students' info. The persistence context in that stateful session bean has the type of PersistenceContextType.EXTENDED. The reason I choose a stateful session bean and an extended persistence context is that I want to write something like this without facing the lazy initialization exception:
<h:dataTable value="#{backingBean.teacher.students}" var="student">
    <h:outputText value="${student.name}"/>
</h:dataTable>Because my session bean is stateful, I have a method with the @Remove annotation. This method is empty because I don't want to persist anything to the database.
Now, my question is: How can I make the @Remove method of my stateful session bean be called automatically when my JSF page finishes being rendered?

  • How do i get back my stateful session bean after it has been passivated

    hi ,
    How do i get back my stateful session bean after it has been passivated by container.
    i'm confused that is it possible or not .......give me answer
    i've one stateful sessionbean which i'm accessing throgh my normal java client . now what i'm doing is when i first time call a method it is running ......then i'm shutting down the server jboss .......it is calling my ejbPassivate() method ... at this particular time client program doesn't do anything.....
    now after i restart my server i'm again calling back that business method with that last object reference.......it gives me the exception given below.....

    Stateful session beans are not persisted across restart of the EJB server instance(s) hosting them. You can't treat a Session bean as one would an entity bean.

  • Stateful Session Bean, After remove is called how do I create a new SFSB?

    The application when is deployed creates a new SFSB, after the remove method is called the SFSB does not exist anymore, also the same happens in a timeout. How do I create a new SFSB without restarting the server?
    I am using EJB 3.0
    I don't understand really how in a shopping cart examples through different uses the correct SFSB is called for each user, with EJB 3.0
    Also how should I store the SFSB, I always called it through JNDI lookup.
    Thanks,
    Zoe

    How do I create a new SFSB without restarting the

    I am using EJB 3.0
    Just as you created the firwst one. Assuming that you have a handle to the home object stored somehwere from your first call, you use home.create(var1, var2) or else look up the home using jndi and then call create on the home object.
    I don't understand really how in a shopping cart
    examples through different uses the correct SFSB is
    called for each user, with EJB 3.0
    Through your remote object. Each user has got his own remote object and for SFSB, one and only one bean is tied to a remote object. It's the container's responsibility to relate the remote object and the bean.
    Also how should I store the SFSB, I always called it
    through JNDI lookup.Store? Use a handle and if the handle is lost or an attempt to retrieve the remote object using the handle fails, look at #1 above (lookup home, create on home etc)

  • Share stateful session bean in JSF managed beans with different scope

    Hi,
    I have a JSF application and I want to try to use of stateful session beans.
    So I created a new stateful session bean and its local interface.
    @Stateful
    public class StatefulSessionBean implements StatefulSessionBeanLocalInterface{
    private String name;
    @Local
    public interface StatefulSessionBeanLocalInterface {
    ...In my JSF application I have a mananed bean with session context which registers the new interface by
    this annotation
    @EJB(name="sessionbeanref", beanInterface=StatefulSessionBeanLocalInterface.class) and set the name to something.
    Now I want to fetch this name in another managed bean with request scope. So I looked up the bean and tried to get the name.
    StatefulSessionBeanLocalInterface = (StatefulSessionBeanLocalInterface) new InitialContext().lookup("java:comp/env/sessionbeanref");
    System.out.println(currentmailingbean.getName());but the name is null.
    Why?

    The xsd was created via the netbeans J2EE enterprise application dialog and I think its the most recent.
    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">All other annotations seem to work.
    Wouldnt the lookup completely fail if the deployment process thought that it is version 1.4 ?

  • How to call the show method of Popup from backing bean?

    Hi!
    I wanted to display the results of a search form in a dialog that is placed in popup.
    That is The content of the popup will be rendered from the backing bean, dynamically .
    And so when the form is filled and the submit button is clicked, the form fields have to be submitted to the server, and the results are to be displayed in the dialog,after the PPR response has arrived, and not at the time of calling the PPR.
    Could you explain How this can be achieved?
    Samba

    Samba,
    The fix for the popup in a template is to give the template an id say "template" and reference the popup in the JavaScript as "template:popupId", where popupId is the value of the af:popup's id attribute.
    Regarding DWR, Joe really did a nice job with this framework. I have to say he got my attention. The one issue though is that JavaScript is an absolute must when using DWR and other frameworks that have a heavy JavaScript tilt. Dealing with JS can be a bit of a hassle due to x-browser idionsyncrascies as well as slow exection of JS. That said I believe Joe has one of the best JS solutions around.
    On the flip side of this ADF Faces is trying to do something a bit different. Firstly, we want to avoid JS. The user should handle as little as JS as possible. In addition,
    ADF Faces has the benefit of a server-side component framework we want to leverage this to make sure there is a limited amount of JS execution on the client.
    So if you want to work with JS, DWR is a good solution. If you want to work with, Java, standards, and a great tooling environement ADF Faces is a better choice.
    Finally, "Reverse AJAX" is a marketing term for "Push". You probably have also heard the term Comet. There are some varations on the protocols used but all-in- all. We are talking about one thing, the ability for the server to "Push" information to the client. Luckily, we provide this ability in a feature called active data channels. You will see this feature in the next preview. By setting an attribute value in a pageDef trees, tables, and BAM components can recieve data from the server via "Push".

  • Accessing the same stateful session bean from multiple clients in a clustered environment

    I am trying to access the same stateful session bean from multiple
              clients. I also want this bean to have failover support so we want to
              deploy it in a cluster. The following description is how we have tried
              to solve this problem, but it does not seem to be working. Any
              insight would be greatly appreciated!
              I have set up a cluster of three servers. I deployed a stateful
              session bean with in memory replication across the cluster. A client
              obtains a reference to an instance of one of these beans to handle a
              request. Subsequent requests will have to use the same bean and could
              come from various clients. So after using the bean the first client
              stores the handle to the bean (actually the replica aware stub) to be
              used by other clients to be able to obtain the bean. When another
              client retrieves the handle gets the replica aware stub and makes a
              call to the bean the request seems to unpredictably go to any of the
              three servers rather than the primary server hosting that bean. If the
              call goes to the primary server everything seems to work fine the
              session data is available and it gets backed up on the secondary
              server. If it happens to go to the secondary server a bean that has
              the correct session data services the request but gives the error
              <Failed to update the secondary copy of a stateful session bean from
              home:ejb20-statefulSession-TraderHome>. Then any subsequent requests
              to the primary server will not reflect changes made on the secondary
              and vice versa. If the request happens to go to the third server that
              is not hosting an instance of that bean then the client receives an
              error that the bean was not available. From my understanding I thought
              the replica aware stub would know which server is the primary host for
              that bean and send the request there.
              Thanks in advance,
              Justin
              

              If 'allow-concurrent-call' does exactly what you need, then you don't have a problem,
              do you?
              Except of course if you switch ejb containers. Oh well.

  • Defining Stateful Session Bean Methods as Idempotent or NonIdempotent

    Hi,
              Is there any way to define a stateful session bean method as idempotent
              or non-idempotent. Is there a patch to do this if u want it in Weblogic
              6.0
              Thanks
              Sameer
              

    No, not right now... but BEA is looking into it. It has not been slated for
              a product release.
              They understand that certain getXXX methods of a stateful session bean could
              be idempotent and will look at that in the future.

  • Error in updating secondary stateful session bean

              Hi all,
              I have set up a cluster of 2 managed servers with WebLogic 6.1. I have a
              stateful session bean and several stateless session beans. the stateful
              session bean keeps user info and limited cached objects, all are
              serializable. it seems working fine, even after killing any one of the
              servers, as long as one is alive. a java application client creates a
              stateful session bean first, then calls stateless session beans with the
              remote interface of the stateful bean as a method parameter. No problem
              when stateful session bean is created. However, each stateless bean method
              generates the following error message if I turn the debug on (level 64). No
              exception stack traces, and all methods execute successfully.
              <Error> <EJB> <Failed to update the secondary copy of a stateful session
              bean from home:clientsession>
              I wonder what causes the error, and why it tries to update the stateful
              session bean. in all stateless session beans, only read into the stateful
              bean.
              Thank you,
              Fujin
              

    This has been fixed in WLS 6.1 SP2.

  • Losing UserTransaction state in Stateful session bean

    I have a UserTransaction I wish to begin and commit in different methods of a Stateful session bean. I have 2 methods to test this on the session bean:
    public void beginTransaction()
    trans = context.getUserTransaction() ;
    trans.begin() ;
    public void commitTransaction()
    trans = context.getUserTransaction() ;
    trans.commit() ;
    If I call these methods from one Perform method in a Struts action all works fine. If I call the methods in different Struts actions (storing the session bean handle on the HTTPSession in the first for retrieval in the second) the second call fails with the following exception:
    java.lang.IllegalStateException: No active Transaction
    The state of the transaction on the second call is STATUS_NO_TRANSACTION. I am certain that I have lost no state on the session bean and that using handles gives me the correct bean since I have written some state to test this. Basically something seems to close the transaction between the end of the first Perform method and the beginning of the second (I am of course assuming this is a valid thing to do).
    My session bean descriptor has <transaction-type>Bean</transaction-type>, and I am using OC4J.
    If anyone can point out what it is I am doing wrong I would be grateful!
    James.

    Sorry, I have re-checked my code and I believe I found the problem.
    I was beginning my transaction inside ejbCreate() and trying to commit/rollback in another method. This works in JBoss 3.2 but does not work in either OC4J or WebLogic 7.
    If I begin my transaction in a business method and commit/rollback in another method, everything works fine. (It also seems to work fine in 9.0.3 this way).
    So I am not sure whether this is a bug in 9iAS/WLS, or a bug in JBoss, or something that is left "vague" in the J2EE spec. Unfortunately, examples on bean-managed transactions are thin on the ground generally (the usual advice being not to use them, which I definitely agree with!).
    If you believe that the behaviour I describe is a bug in 9iAS, I can send a simple EJB test case.

  • Handling Transaction in Stateful Session Bean

    I wrote a public method like public void doTransaction()
    it will call 2 private method, like: methodA and methodB
    Both private methods have db accesss statement and will update the db. They got different db connection and will close the connection when method call finished.
    How to include them to one transaction? I want to be able to rollback the job of the first method when I catch exception thrown by the second method.
    I tried simply define transaction type of the public method to be Container and Required. But it doesn't work, the first method doesn't rollback. Of course I can let the 2 private methods share a same connection and commit after finishing calling them. But how if they are in different DB?

    Ok... Here it goes...
    You can do it in the following manner.
    As you said you have got 2 private methods doing d/b updates and these are called from a public method.
    Stateful session beans since associated with a client across methods, you can take advantage of it. Write your own user defined transaction.
    Begin the transaction scope in your public before calling the 1st private method. Call the 2 methods in a try block. Once you are done with these methods, you can commit and end the transaction. If you get any exception, rollback the transaction in the catch block. Otherwise if u get any exception in the 2nd method, you can rollback the transaction there itself.
    Stateful session beans lets u allow to spawn the bean managed transaction across methods. you can begin your transaction in one method and end it in a differnt method or you can end the transaction after calling the methods.
    The problem you are dealing with can typically very well handled by writing bean managed transaction.
    Hope this helps. If you need anymore clarity on my solution, please let me know.

  • EJB 3.0 Stateful session bean shared between Servlet's

    Hello
    I have a bit of a noob question regarding Stateful sessions beans.
    I am wanting to know if there is a way that I can share an instance of a session bean between multiple HttpServlet instances?
    I am sending XML messages from a mobile J2ME application, there will be several http POST's made from the mobile client to the server. I would like these multiple POST's to be passed from the handling servlet instance to the same uniquely identified single stateful session bean instance (i can then @Remove the stateful bean when I have finished my several requests).
    I would greatly appreciate any tips anyone could give me.

    If not, your only option is to maintain the
    association yourself by creating a unique id for
    each
    conversation and storing that id along with the SFSB
    reference in the ServletContext. Then you'll
    need to pass the id in along with each invocation to
    retrieve the appropriate SFSB reference.Thanks for your reply.
    Will I always be presented with the same ServletContext instance? Even if the time between requests might be many minutes? Where can I learn more about how to use the ServletContext?
    Thanks!

  • Help!!! Stateful session bean clustering

              I posted this message on interest.clustering.in-memory-replication. But there is
              no answer at all. Could anyone give me
              some hints? Thanks a lot. I am a student and this work is part of my course project.
              It is due soon.
              =================================================================
              I have a big problem to get stateful session bean in-memory replication run on
              clustering. I have three server instances on three nodes and there is always errors
              from the server instance like this when I run the client to invoke the bean methods:
              <Jan 4, 2002 6:47:31 PM EST> <Error> <EJB> <Failed to update the secondary copy
              of a stateful session bean from home:stateful.ejb.AgentSTF>
              Besides, the load balancing can not work probably too. Below is what I get.
              Statistics for different servers:
              "myserver" processed 160 (12%) of 1311 invocations "ejbperf-3" processed 1151
              (88%) of 1311 invocations
              End Client...
              Load balancing works fine with stateless and entity bean.
              Any comments are greatly appreciated.

  • How to get the Stateful Session bean instance in the second call

    Hi,
    I am new to EJBs. I have made a Stateful session bean on the first jsp page. In this page i am setting certain member variables of the EJB. Now in the second page i want to get these stored values in the EJB.
    In the second page do I...
    1. Store the instance of Remote Interface in the Session Context of the first JSP page and then in the second page get the Remote interface stored in its session context and call the business functions to get the values. If this is the case then what do u mean by Stateful Session beans??
    P.S.- This works fine.
    2. Try to get the Remote interface of that particular instance of the EJB(in which the values were stored) and call its business functions. IF this is possible. How do i do it??
    thanks in advance
    Anurag

    Hi,
    thanks for information. But i have one question. In a stateful session bean why do we have to store the Remote Interface on the client side.
    I expected in the second jsp page when i do a lookup or create, the container/server should find out whether there is a session bean already created for this session if yes, then return that particular instance of the session bean else create a new one.
    If this is not a possible case then a stateful session bean is nuthing but an instance of an object in the EJB container which does not get destroyed unless there is a time out or the remove method is called. It has nuthing to do with session because throughout the session I have to store the remote interface in the session context of the client( the client here means the jsp).
    thanks in advance

  • Call the remove() in the implementation of the finalize()

    In weblogic61 Is it recommand to call the remove() in the implementation of the
    finalize() ?

    Hi Yafit,
    If you mean ejbRemove, there is no need to call it
    from finalize(). It's a bean lifecycle method and
    it's called by the container.
