Calling EJB 3.0 from ALBPM

Hi,
I tried calling EJB 2.1 from ALBPM and it worked.
But I was nto able to call EJB 3.0.
Is calling EJB 3.0 supported from ALBPM 6.0.2?
If yes, how to call a business method in EJB 3.0?

Frank,
Thanks. The @LOB annotations are missing.

EJB 2.1 session bean calling EJB 3 session bean?

I have a WL 10 (JDK 1.5/EE 5) server that has several EJB 3 stateless session beans deployed and working well. But now I need to allow a JBoss 3.2.3 (JDK 1.4) EJB 2.1 session bean make remote calls into these EJB 3 EJBs. Can this even work?
It seems to me that EJB 3 calling EJB 2 would be fine, but not in the reverse?

How can I set dependencies to get this running?
Thanks to all
       Volker

Hi,
Is it available in the interface you are using..
If the answer is yes.. you might have probably forgotten to deploy the EJBs ear file after making the changes..
Rebuild it.. and deploy the EJB s ear file again..
It will solve the problem.. If that also does not work,it might be a problem with the cache.. restart the server..
It should work now !

How to Call EJB from coldfusion

I need to call EJB that's created in JBoss from coldfusion.
I'm getting different errors depending on how I set the home object
and provider url.
If I prefix provider url with jnp://, then I get the
following error
The connection to the remote JNDI server on host jnp at port
1099 has failed (as have all backup hosts listed, if any) - please
verify that the server is running and the NamingService is
available
If I take the jnp out and keep just the ip address and port,
then i get the following error
null (no security manager: RMI class loader disabled).
So I'm not sure what the issue is and I haven't used this
feature before.
Here's my code

I tries to call custom EJBfrom custom component received

How can I call EJB from JSP/Servlets in iWS?

Hi!!
My JSP/Servlets are on iWS, and I deploy EJB on iAS.
In this case, I don't know how JSP/Servlet call EJb on iAS.
I'd like to know how I can set JNDI name in JSP/Servlet on iWS.
I will thank you if you give me a simple example source using JSP/Servlet
and EJB.
Thanks in advance!!!
- Park-

Park,
Why Are you running your JSP/Servlets in iWS instead of iAS? For whatever
reason,
look at the Converter sample from iAS. You will be doing RMI/IIOP in this
case and the sample explains in detail what to do.

Call EJB from a XI Javamapping

I have developed a simple EAR which contains a CMP with local and remote interfaces. This cmp may be successfully called using the remote-interface from a client (j2se) project. Now i like to call the same CMP from within a XI JavaMapping. In the execute method i am using the following code:
          InitialContext ctx;
          MeraConfigurationLocal configLocal = null;
          try {
               ctx = new InitialContext();
               Object obj = ctx.lookup("localejbs/mgb.ch/XIMera_EAR/MeraConfigurationBean");
               if (trace != null)
                    trace.addInfo("Got object from jndi: "+obj);
               MeraConfigurationLocalHome configHome =     (MeraConfigurationLocalHome)obj;
               if (configHome !=null) {
                    if (trace != null)
                         trace.addInfo("ConfigurationLocalHome: "+configHome);
               configLocal = configHome.create();
          } catch (Exception e) {
               throw new StreamTransformationException(e.getMessage(), e);
          int port = Integer.parseInt(
                    configLocal.ReadParam(MeraResourcePoolDispatcherService.CFG_GENERAL_LISTENER_PORT));
          if (trace != null)
               trace.addInfo("Got listenerport from localejbs/mgb.ch/XIMera_EAR/MeraConfigBean: "+port);
after calling ctx.lookup ... i got the following traceentry in xi:
<Trace level="1" type="T">*** START APPLICATION TRACE ***</Trace>
<Trace level="2" type="T">Got object from jndi: [email protected]30</Trace>
<Trace level="1" type="T">*** END APPLICATION TRACE ***</Trace>
when i try to cast this obj into a MeraConfigurationLocal the system is throwing a ClassCastException

Call ejb from browsers

Hello Developers!
I deployed my ejb to OAS4081. I call that
from JDeveloper so it good. But when I try
to call from applet in IExpl5 I can't
instantiate the ORB. I've got a com.ms.security.SecurityException : oracle.oas.orb.CORBA.ORB.init
I coded the CLASSPATH(oasoorb(yoj),client,
ejbapi...) perfectly, I think.
If anybody could help, please...
Thanx!

Hi there,
          I saw someone on this group had a problem to locate proper classpath
          to call EJB from JSP. I thought if you call EJB from classpath, you are
          calling the bean. But you loss all the EJB functions. To be able to utilize
          EJB features like object pooling. You need to call it from Weblogic server
          using url/jndi, not from the jar directly.
          Any comment? Am I right?
          BTW, my question about calling EJB from JSP means calling through URL,
          not a local path.
          Thank you

Calling EJB from an applet in 9iAS Release 2?

Hello!
In 9iAS Release 1 it is not so easy to call an EJB from an applet. First the applet needs special privileges and then the applet starts only once. The cause of problem is the implementation of ormi.
Will 9iAS Rel. 2 support Applets calling EJBs?

Calling EJB with Annotation not successfull within Netbeans

I am trying to call EJB but my simple program can't find a ejb
within netbeans. I also download a stub file from the admin page and add to the ejb client path. but still without the luck
@EJB
private static ConverterBean converterBean;
public static void main(String[] args) {
// TODO code application logic here
BigDecimal param = new BigDecimal ("100.00");
BigDecimal amount = converterBean.dollarToYen(param);
System.out.println( amount );
}

Thanks for your pointer. Could you please help me out with a small code snippet example?
I want to make use of this existing bean (AMSProfileServiceBean ):
@WebService(targetNamespace = "http://www.ttt.de/ota")
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.BARE)
// standard EJB3 annotations
@Local(AMSAgencyWSPortType.class)
@Stateless
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
// jboss propriatary annotations
@WebContext(transportGuarantee = "NONE", secureWSDLAccess = false)
public class AMSProfileServiceBean extends AbstractProfileBuilder implements AMSAgencyWSPortType
private static Log log = LogFactory.getLog(AMSMappingServiceBean.class);
@EJB(mappedName = "PotsdamProfileService/local")
private PotsdamProfileService profileService;
private Security              security;
@EJB
private OTAProfileBuilder     otaProfileBuilder;
@EJB
private OTAProfileUpdater     otaProfileUpdater;
@Override
public OTATTProfileReadRS otaTTReadRQ(Holder<Security> wsseHeader, OTATTReadRQ request)
...in my soap-connector :
@WebServiceProvider(wsdlLocation = "WEB-INF/wsdl/PotsdamAMSAgencyWS.wsdl", targetNamespace = "http://www.ttt.de/ota", serviceName = "PotsdamAMSAgencyWS", portName = "PotsdamAMSAgencyWSPortType")
@ServiceMode(value = Service.Mode.MESSAGE)
public class PotsdamAgencyWSProvider extends WSProvider implements Provider<SOAPMessage>
@Resource
WebServiceContext     wsCtx;
...A small example would be really appreciated.
Thanks.

Calling EJB from Oracle via IIOP

I've spent the last two days trying to figure out how I can call an
EJB from an Oracle Stored Procedure. I first looked into WLS JNDI
(Using WLInitialContextFactory ), but my collegue recommended I look
into IIOP because it is "less proprietary". I was able to get a WL
example working that does a lookup on an EJB and "narrows" the IIOP
object...so it looked promissing, but then I tried to load the JAR
into Oracle and it said:
"referenced name javax/rmi/PortableRemoteObject could not be found"
So I did a quick check and it looks like this didn't come into
existance until JDK 1.3. By all accounts, Oracle 8.1.6 supports JDK 2
(1.2). So now I'm stuck. I've got a few examples about connecting to
the Oracle ORB using session-iiop, but I don't know if Weblogic will
be able to work with this. I don't know how I'd even call it because
the URL requires an Oracle SID...so now what? I see three options.
Please let me know which would be best (or another option that I'm
missing)
1. Try connecting with Weblogic "T3"
2. Try to get the right combination of classes loaded so 1.2 can work
like 1.3
3. Use the Oracle IIOP (I have no examples for connecting to other
ORBs so I have no idea how to lookup objects).

1. Try connecting with Weblogic "T3"It depends on what version of WLS you are using. If you are using 6.1
then you are out-of-luck because this only support JDK 1.3.1.We are using WLS 6.1 and Oracle 8.1.6. There's got to be a way to
connect what is essentially a 1.2 JVM to a 1.3.1 JVM. On my way home
yesterday I was wondering if just straight RMI would work...although
we need to encrypt the connection. I've seen several people talk
about calling EJB's from stored procedures so it seems like there is a
way. Any other ideas?The really gross way is HTTP. In a previous life I had a customer use
oracle's HTTP plug-in to do this. You could probably invert the
problem also. I.e. write CORBA objects that sit inside an Orb hosted
in WLS and invoke on those using oracle's CORBA support. But HTTP is
probably the way most likely to work. You probably couldn't use RMI
over HTTP either - you would have to write a servlet that delegated to
your beans.

Calling EJB from Java Stored Procedures

Hi,
I am trying to call an Enterprise Java Bean from stored procedure. This stored procedure calls a java program. As long as it is a simple java program it works fine and loadjava.exe does not give any problem (neither compile-time nor run-time).
It is not working when I am trying to call EJB from it. It is giving compile-time error.
If anybody has implemented the same please suggest how to go forward.
thanks in advance,
Shashank Agarwal

I tried the same thing without any luck. I assume you are using OC4J for your EJB ...
The compiling issue may be because you don't have the classes in your EJB client jar loaded into the database. Once those classes are loaded, you should loadjava without any problem.
However, you won't be able to call the EJB server because the EJB client (your Java code in the DB) will need the OC4J environment (oc4j.jar). I have tried to load oc4j.jar into the DB as well, and that was a big mess and nothing worked. My DB is 8.1.7, maybe the new 9i have OC4J libs bundled?!?
I looked around and only found 2 alternatives:
1. Write a JSP page that acts like an EJB client, then use URLConnection in your DB java code to send params to the JSP for it to invlode the EJB
2. Replace the JSP with RMI code, and use RMI instead of URLConnection in your DB code to invloke the EJB client.
If you find any other solution, please share it here.
Good luck!

Calling EJB from XI Mapping

Hello,
i try to call a ejb (deployed on the same machine) within a message mapping (userdefined function).
Is there any documentation how to do the jndi lookup?
Do i have to pass user credentials in order get working jndi-lookups. Currently i get only sap....UnsatisfiedReferenceImpl Objects from the context.lookup(...).
As far as i can see there is no binding of my ejb visible for lookups (tracing the content of context.list("")).
Do i have to load a foo_client.jar into xi or not. Are there other jars to load into xi to get it work .....?
Thanks
Peter
