Unable to deploy stateful session bean in weblogic6.1

Hi there, I am trying to deploy an OrderSession.jar into weblogic6.1 sp 5. But it keeps throwing errors whenever I install the jar file. Following is the error message received. Can someone help me what causes this problem and how to solve it? Thanks!!
I have copied part of the error messages as it is too long. Hope the message helps. There are 3 sections of it.
Part 1:

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

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).

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:

Does anyone know what this error means and how to resolve it. I searched the forum but only found errors that look like this relating to XI not to Webdynpro.......

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

Hi,all
I create a stateful session bean in jbuilder 7 and deploy it to weblogic7,it
successed.The Home interface have a method like this:
public TestRemote create(int var) throws RemoteException,CreateException;
But the client test bean call the create(int var) method throwing
a exception :

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

Hello Björn,
I am not quite sure what your problem is but did you have a look at these articles:
http://help.sap.com/saphelp_nw04/helpdata/en/4d/993441c73cef23e10000000a155106/frameset.htm

I hope they can give you some idea.

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
Vijay

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.

Stateful session bean does not rollback TX

I am unable to figure out why my stateful session bean is unable to rollback transactions
when I throw an EJBException. My stateful session bean has an ejbCreate method
which calls 2 other creates on 2 entity beans. If one of the entity beans successfully
creates and the other throws a CreateException, i catch it and throw an EJBException.
The created entity bean should roll back but it doesnt. Can it be because I
am calling the beans from within the session bean's ejbCreate method?
All beans are set to transaction REQUIRED, using bea's TXDatasource, and running
WL 6.1 sp2 on windows 2000.
help!

Session bean create methods run in an unspecified transaction. So your two calls to the
entity bean are running in separate txs.
