  • Deploying Stateful Session Bean

    hi!
    I've got a problem when deploying a Stateful SessionBean. It worked well for about 1 week. I changed a little thing in the BeanClass, and afterwards only got deployment errors. taking back the changes had no effect.
    Furthermor the Error seems to be nonsens, because I deploy from a EAR, and this ear contains all Files of the Stateful SessionBean. The container seems to have problems to read the jar file within the ear file ...???

    hi Jeff!
    I tried some different tasks.
    1.) removing all deployments (incl. app in server.xml) -> still error
    2.) manually deploying to a "virgin" container -> still error
    3.) manually deploying an old and stable version (runs on a colleages oc4j instance) -> still error
    4.) copying app-dirs + config-dir from a colleage (its his running instance) -> STILL ERROR!!
    5.) copying his whole J2EE-dir -> deployment works!
    It looks like, that one of my deployments (out of Jdeveloper with admin.jar) has kicked my container and the container kept in tilt mode (to use a little flippermachine slang ;o)
    Besides from joking, I still think it's a serious thing. I'm now going to install a whole fresh instance of Jdeveloper and OC4J. Hopefully afterwards I won't have these probs again.
    If someone @ Oracle wants to take a look at these instance (like bugsearching) dont hesitate to contact me (I'll keep both version of the OC4J, running and tilt one).

    Try unpacking the jar using a compression tool like winzip or any other tool and just check if extracted classes files are in the same package hirerachy as u have coded if not that is would be the problem

  • Deploy Error when using Stateful Session Bean inside Webdynpro

    Hi,
    I'm trying to create a webdynpro project that uses a stateful session bean
    I have created DC's for a EJB Module project, Enterprise Application and Webdynpro component. Created the bean, built it, added it's package to the public part, added the EJB Module to the EAR project. Built the EAR project. Added the EJB Module project and Enterprise Application project as a used DC in the Webdynpro DC.
    In the Webdynpro DC I added com.sap.archive-packaging.default.update-descriptors=true in the build.properties file of the cfg directory. (using the navigator view) That resolved an error while building it.
    Deployed the Enterprise Application DC without problems.
    Tried to deploy the Webdynpro DC but I get the following error:

    Default is 30mts.
    This is done as a parameter in orion-ejb-jar.xml. Please look at the EJB Guide at http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/a97677/dtdxml.htm#634197 for details

  • Stateful session bean hot deployment error?

    Hi,
    i'm getting an exception ...
    1. Deploy a stateful session bean.
    2. Hit the server and create an instance, then remove it.
    3. Change Stateful session bean source compile and hot deploy it.
    4. Hit the server and try creating an instance...exception !!!!
    "IllegalArgumentException: Object is not an instance of declaring class"
    Please help!!!

    Hi Navin,
    Firstly could you let me know , what option did you set in Jdeveloper to perform hot deploy ??
    I would like to hot deploy Stateless Session beans on Embedded OC4J using JDeveloper.

  • 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.

  • How can I create a stateful session bean?

    I created a stateless session bean. Now I want to make it be a stateful session bean. How can I do? Where can I find a session bean sample?
    Thanks
    Qing

    Look at this site. The tutorial explains it all.
    Well if you want to convert your stateless EJB to stateful, all you have to do is change the deployment descriptor and re-deploy the ejb. You should be ready to go.
    All the best.

  • 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 ?

  • Web Service from stateful Session Bean deleted after server restart

    Hi,
    i created a stateful session bean and from this a web service.
    I am able to deploy it and it works really fine.
    My problem is: after a server restart the web service is gone and i
    have to deploy it again.
    I have some other web services (but these are web services from stateless session beans)
    but they "survive" the server restart.
    I don't want to deploy the web service after every server restart, did I forget something or
    is it a general problem of stateful session beans or web services?
    Thanks in advance
    Jens

  • 1) Second thread call to stateful session bean.

    Hi Friend,
    I read your threads on otn and i compared your problem with us and i analysed that your application and my application is same, So Plese can you help me in some issues.
    Friend, Please help me in these issues, Thanks for this
    We have very big ADF Swing+BC Application and deployed as Stateful Session Bean. in my application there are 500 Application Modules,For each application module i created Stateful session beans and deployed it on OC4J Container but when working on deployed application then i am getting time out error after 15 min of working.
    1). I set that parameter that you mentioned i.e jbo.ejb.txntimeout = 86400,but still it is giving me same error.
    2). Second Issue is of ---ORA-01000: maximum open cursors exceeded
    For this issue i chaged the Database Parameter i.e OpenCurser=2000, but still it is giving me same error,
    is there any parameter on application module required to change so that this error will not come.
    3). When i close the form then application module is not releasing database connection.
    4). (oracle.oc4j.rmi.OracleRemoteException) Second thread call to stateful session bean
    This error is also coming when I am using deployed application for long time i.e more than 15 min for Heavy Transactions

    Hi Suyog,
    How r u?
    We all are fine.
    I alerady tried for the Max Curser Property but it is not helpfull.
    I think again i have to go for closing opened db RS and statements.
    Thanks

  • Problem using application client for local stateful session bean

    Hi,
    I have deployed a local stateful session bean in Sun J2EE 1.4 application server.
    On running the applclient for the stateful session bean application client i get the following error:
    Warning: ACC006: No application client descriptor defined for: [null]
    cant we use application client for local stateful session beans. becoz the application runs smoothly when i changed the stateful sesion bean to remote.

    Hi,
    No, an ejb that exposes a local view can only be accessed by an ejb or web component packaged within the same application. Parameters and return values for invocations through the ejb local view are passed by reference instead of by value. That can't work for an application client since it's running in a separate JVM.

  • HttpSession vs. Stateful Session Bean ---- when State Session is large

    I hope most of the people come across with this issue where to put the state
    for the internet/intranet based applications when they are using
    servlet/jsps calling session beans. Weblogic 4.5.1 does support httpsession
    in-memory replication for the servlets but the stateful session beans are
    not replicated in clustered environment. Plus with stateful bean u get
    activation/passivation overhead too. So one tempts to use stateless session
    beans and store state in httpsession?
    Then what is the upper limit for the session state one can put in
    HttpSession with the weblogic? Is there any way to configure it?
    One way to overcome the httpsession size limitation is to use database for
    storing state and just store some unique Ids for the session info in
    httpSession. But then there will be overhead for database connection?(jdbc
    connection pool can provide some help here). So what is the recommended way
    for doing this provided few thousand concurrent clients with session size
    say exceeding 4kb per client?
    Thanks
    Usmani

  • When will Stateful Session Bean be removed?

    I develop a stateful session bean and deploy it in the oc4j server successfully.
    I write a java GUI Frame.
    This Frame call this stateful Session bean and get some data,
    and hold its remote interface reference as Frame's private member.
    Code like that:
    public class CargoFrame extends JFrame
    //private member
    private DataPager dataPager;
    I found that before i release CargoFrame, Stateful session bean will be removed.
    And System report session time out.
    And i want to know when stateful session bean will be removed,
    and how to set the session time?

    Default is 30mts.
    This is done as a parameter in orion-ejb-jar.xml. Please look at the EJB Guide at http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/a97677/dtdxml.htm#634197 for details
