Does Webservices support Statefull EJBs?

Hi all,
My questions are
1.Is it possible to implement stateful EJB'S using webservices?
2. is it possible to identify dynamically the webservices in a distributed environment.
i mean is it possible for the server to identify at runtime that the webservice is
local or remotely located? is this a standard way for identification or vendor specific?
In concurrance does it make any difference in performance by accessing webservices
from remote or localhost?
would be delighted to have some insight and some documentation regarding it.
thanx in advance!
regards

Hi Arif,
You can use a conversational web service to maintain the conversational
state of client across multiple calls, just like a stateful session EJB does
for a web/java client. However, please don't confuse this with using a
stateful session EJB from within a web service using an EJBControl. The
state maintained by a stateful session EJB invoked through a web service,
does not span across multiple client calls to the web service. Hence, even
though your web service might be using a stateful session EJB behind the
scenes, the state of the client should be maintained in the web service
itself, and not in the stateful session bean.
Regarding your question about the performance implications of having a local
webservice as compared to a remote one, as of now we do not do any
shortcircuiting of the calls to a local service. However, you obviously
would still see a better performance while using a local service as compared
to a remote service, due to the network overheads and latency.

Weblogic 8.1 SP2 does not support 'Order by' clause in EJB-QL

It seems that Weblogic 8.1 SP2 does not support 'Order by' clause in EJB-QL. EJB 2.1 spec supports 'Order by' clause in EJB-QL. Am I right when I say that it indicates : "Weblogic 8.1 SP2 does not support EJB 2.1" ? In that case, what can be the alternative since I am using Weblogic 8.1 and I require 'Order by' clause in Ejb-QL as well.

In WL 8.1 SP4 I can use the ORDERBY just fine.
Try ORDERBY instead of Order by

Does Tomcat support EJB's?

Does Tomcat support the deployment of EJB's? If so how do you go about deploying them. i cant seem to find anything on the apache web site

Hi,
Does Tomcat support the deployment of EJB's? If soNo, Tomcat is the open source servlet Container by Apache and to my knowledge they dont have any ejb Container as open source,so you have to make the tomcat configure with the EjbContainer for EJB to be deployed.......
how do you go about deploying them. i cant seem to
find anything on the apache web siteYou require the EJB Container for deploying the EJB's.You can go for Jboss,Weblogic,Websphere.....

Does OC4J support RMI/IIOP connections ?

Hi,
I have only one question :
Does OC4J support IIOP connections ?
I'd like to connect as EJB client to OLAPService on Oracle9i server (CORBA object), but I can't.
Thanks in advance

Thanks for your timely post Debu.
I would like to state that I read and followed the guides (same files as those ponted by the links you just provided) and tried this:
1. Sample J2EE Application using ORMI in OC4J Standalone (this works ok)
2. Same but now using ORMIS (this also works fine)
3. Tried same J2EE App using IIOP; took these steps:
3.1 commented out the rmi.xml security lines,
3.2 enabled ports in internal-settings.xml,
3.3 changed the jndi.properties - now using corbaname URL,
3.4 enabled the IIOP stub generation in the JVM settings at oc4j startup, and finally
3.5 deployed the EAR using the generateIIOP flag.
The result: the exception I posted above
4. Tried with IIOP/SSL, did these steps:
4.1 configured the keystore settings in both internal-settings.xml and ejb_sec.properties
4.2 and added <ior-security-config> config elements to orion-ejb-jar.xml.
The exception here is a little bit different:
client started...
In IIOPInitialContextFactory ..
In IIOPInitialContextFactory getInitialContext..

"Multicast" support for EJB-EJB calls to cluster

What I have to work with:
+ WebLogic Server 5.1 cluster
+ Stateless session EJBs
What I want to do:
+ Be able to know list of available servers in the cluster
and use this list to broadcast same information to all EJBs
with same name in cluster
+ I understand that the cluster-aware EJB stub has this list
when a client gets a home reference to the EJB Object
+ I have not seen any specific WebLogic API to get this list
either by accessing the cluster-aware JNDI table or the
cluster-aware EJB stub.
+ Othwerwise, I would then need to implement my own server
list manager to get this list. Such task should not be that difficult.
Why I want to do the above:
+ I would like to implement a EJB sendAll() method that will
send the same request to all EJBs of the same JNDI name in the cluster.
+ Please correct me if I am wrong but I have not seen anywhere
in the WebLogic 5.1 documentation regarding the automatic multicast
ability of broadcasting EJBs calls via EJB-to-EJB communication to a
cluster.
+ I understand that multicasting is only used internally, ie,
heartbeats.
Plus, I believe that RMI does not support multicasting.

I'd like to hear a bit more about what you are trying to do. (at a
higher level)
RMI / EJB is a point-to-point model. A client is making an RMI call to
a server. Granted, in our clustering solution, there may not be one
physical server, but the idea is to give the appearance of one big,
reliable server.

JDBC driver does not support XA, hence cannot be a participant in two-phase

Hi
I have a question, we enabled "One Phase Commit", even though we are getting "javax.transaction.xa.XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source =nested exception is: javax.transaction.xa.XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source". Why is that?
Thanks
Edited by: user7256072 on Apr 10, 2012 12:35 PM

Is there more than one resource participating in the transaction?
If this is the case, and the resources are for example a database and JMS, you can emulate XA
by using the logging last resource setting on a non-XA driver.
An example of the above is presented here: http://middlewaremagic.com/weblogic/?p=7716 (the section my first JavaEE6 application)
Here a stateless EJB is used that has an insertPerson method that uses a datasource and JMS in a transaction.

SAP NetWeaver CE 7.1 EHP1 does not support version 1.5 JCA?

Hi,
I've been following the documentation of SAP NetWeaver CE 7.1 EHP1 regarding creation of a version 1.5 resource adapter. When I finally got to "Add/Remove projects" in the server view to test my adapter, I get this error:
The server does not support version 1.5 of the J2EE Connector module specification
Is this true? Then why does the documentation explain how to do it?

Hi Johan,
I agree with you that this does not seem clear enough throughout the Resource Adapters documentation.
Generally speaking about the Developer Studio, there are two equivalent options to add your project (be it JCA, EJB, Web, JPA, etc.) to an EAR project:
While creating your project, you can specify that you want it to be added to an EAR project - either a new one or an existing one (you can create the new EAR project also in the meantime, while creating your JCA project). This is done using the "Add your project to an EAR" checkbox and the relevant dropdown list and button...
Create your project. Then create a new EAR project and specify which projects you want to be included in the EAR.
As I promised, we will improve that part of the documentation for the next release.
Thanks again, and best regards,
Yordan

Does WLS support Debugging Servlets with JBuilder 3 ?

Or should I just buy another web server ?

To be more precise, one dc uses another from a public part that is "assembly" - so it's made the way it should be (both dc's are libraries, one java dc and the second one is server library)

Hi,
we are with NWDS 7.20 but afaik the "J2EE Server Component Library" in your version was replaced by Enterprise Application DCs in the meantime, so it is quite simple:
An assambly PP on a J2EE Server Component Library really does not make sense. The J2EE Server Component Library is the final assembly unit. You may use such a DC in two ways:
1. You want to use the classes that are bundled into the J2EE Server Component Library for compilation in another DC (Java or EJB). To achieve this you may create a COMPILATION PP on the J2EE Server Component Library that references compilation PP e.g. of your java DC. (The alternative is to let the using java DC directly reference the compilation PP of your Java DC.)
2. You have another assembly unit - e.g. an Enterprise application or another J2EE Server Component Library - that needs the classes in your J2EE Server Component Library at runtime. This is done by an application reference (in 7.20 defined in META-INF/application-j2ee-engine.xml of the DC that uses your J2EE Server Component Library). At runtime, the result is that your (initial) J2EE Server Component Library is the "parent class loader" of a using DC.
So indeed, there is no need for a PP of type assembly for a J2EE Server Component Library. This DC does not contrubute anything for assembly into another DC.
Rework your dependencies and PPs.

Help in creating simple statefull EJB program

Hello , i m new to EJB and right now i m developing statefull ejb application. I have created stateless ejb application and it was working well but now facing some problem with maintaining state in statefull ejb application.
Here i m simply developing one counter application ... what i have done is as below ....
============================ CounterBean ================
package ejb;
import javax.annotation.PostConstruct;
import javax.ejb.Stateful;
@Stateful (mappedName="ejb/CounterBean")
public class CounterBean implements CounterBeanRemote {
private int _count;
@PostConstruct
public void initialize()
_count = 0;
public int increment() {
_count++;
return _count;
=================Remote interface for CounterBean==========================
package ejb;
import javax.ejb.Remote;
@Remote
public interface CounterBeanRemote {
public int increment();
=========================index.jsp===================jsp page to get result from ejb ========

===============================================================
so, here every time i refresh my page counter should be increase as i m using statefull bean ...
but its not happening ....
every time i refresh page, all time result coming is only 1 ... its not incrementing .... can any one tell me what i m doing wrong ..... i m not able to maintain state ....
thnks .... please reply ....

The issue is not where to put the lookup code. The issue is that each call to InitialContext.lookup() produces a new Stateful session bean instance. It's the reference that is returned from lookup() that represents the interaction with a particular client. You'll need to store that reference somewhere across the multiple client interactions in order to maintain the statefulness you're looking for. Typically, that means storing it within the HttpSession.

OC4J support local ejb?

It seems OC4J does not support local ELB, as it complains the local-home tag with session tag.

Hi Patrick,
As far as I know, OC4J only partially implements EJB 2.0 -- it
doesn't implement local interfaces. However, there are several,
different versions available. Which version are you using?
If you haven't already found it, there is a version of the pet
store application available for download from:
http://technet.oracle.com/sample_code/tech/java/oc4j/content.html
but it's an implementation of the 1.1.2 version.
Hope this helps,
Avi.
