BaseInfoNotifyLocalHome.java
5.local home jndi name is:BaseInfoNotifyLocal.
6.I deploy the EJB by Jbuilder automatically.
Then I want to access the EJB throuth a servlet by the following code:
Context context = new InitialContext();
baseInfoNotifyLocalHome = (BaseInfoNotifyLocalHome)context.lookup("BaseInfoNotifyLocal");
exceptions:

why?
how can i get a locahome outside a jar?
thank you very much!

Problem calling ejb in oas from non-oracle java client
I am trying to call an ejb that is deployed in OAS 9i from a java server page running another non-Oracle app server.
I continue to get the following error:
java.lang.ExceptionInInitializerError: org.omg.CORBA.INITIALIZE: can't
instantiate default ORB implementation com.visigenic.vbroker.orb.ORB minor
code: 0 completed: No
I don't think it's a classpath problem. In desperation, I added every jar file in the Oracle directory structure to my classpath.
The ejb works fine with jsp on OAS, but (at the moment) using OAS as our production web container is not an option.
Is this even possible?
nullHi Andrei,
is that all you get? No more nested exceptions? This snippet isn't really explaining thery much...

Weblogic startup class: problem calling EJB's
Has anyone ever experienced a problem in using a startup class (registered in weblogic.properties)
and tried to lookup and use an EJB in the same application?
Basically, I have a startup class which registers to receive messages from an
MQ queue, and when it receives a message, it tries to do a lookup of a bean and
use it, but I receive a 'NullPointerException'.
I'm running Weblogic 5.1
(I know that Weblogic 6.0 makes use of MessageDrivenBeans, but my app isn't using
6 or EJB 2.0)
Thanks...Can you post weblogic.log? Are you sure that EJB was deployed successfully.
Also comment the PROVIDER_URL in initial context and see if that solves the problem

The exception is simply a 'NullPointerException' coming from the startup class
(I don't have the old log file or I would include the trace here.). Basically,
when my startup class receives a call to the onMessage(...) method (from listening
for messages), it looks up an EJB on the server, through the InitialContect class
and gets a 'null' returned back, thereby throwing the NullPointerException.
If anyone else is successful in having a startup class which can lookup and call
an EJB within the same Weblogic server, please help.
Thanks again....

Problem calling a EJB Java Client from Java Activity Agent
Hi,
We have a wrapper java class that calls to an EJB through a JNDI lookup. The wrapper class is called from a workflow. The problem is that the call fail with the following message error:
Error : getRemoteHome Lugar: ServiceLocator NamingException Mensaje Error: Receive timed out
Mon Jan 09 15:32:13 EST 2006 Enqueuing VIC/97513 com.tallion.tax.workflow.assessment.Update

The wrapper class has in their classpath a jndi.properties as follows:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=69.0.137.120:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
The call just works fine when we restart the Java Activity Agent and then, after a while it fails again with the same error.
Any ideas/workaround?
Thanks.I have a situation that is a bit similar. I have successfully used beans for storing methods used in JSPs and used by other methods in the same class as was suggested above. Now I would like to break some methods into another (utility) class since they are lower level and can be used by lots of things. They are for database operations (given a String query and String dbname, it queries and returns ResultSet for example). I want to have them in a separate class for reusability and OOP.
I am having problems calling those public static methods in the public class from my bean that communicates with the JSP. I can't compile the class that calls the method in the database ops class. I get an error like :
loginHelper.java:45: cannot find symbol
symbol : variable sqlHelper
location: class dbHelperBean.loginHelper
and when I include the package name in the call I get
loginHelper.java:45: cannot find symbol
symbol : class sqlHelper
location: package dbHelperBean
That's strange since the package of both classes is dbHelperBean and the class is indeed called sqlHelper. I tried to compile it in the same directory as sqlHelper as well. What am I doing wrong?
Thanks for any help. -

How can I set dependencies to get this running?
Thanks to all
VolkerHi,
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 !

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?Jeff,
I am also trying to make an applet client for an EJB deployed to OC4J.

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 AgarwalI 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!

Do i require home & remote interface of that ejb on client side also
Help me, pleasethe problem is actually i require that is specific to websphere
for example i want to call a method ion that ejb
say my ejb name is myejb
so the normal way i should call is
InitialContext initialContext = new InitialContext();
Object homeObject = initialContext.lookup("ejb/MyEjbHome");
MyEJBHome myEJBHome =(MYEjbHome )javax.rmi.PortableRemoteObject.narrow(homeObjectMYEjbHome.class);
myEJB = lSHome.create();
myEJB.someMethod();
but here i am having class for home and remote available
now if other app server i am not having this classes then what to do -
I am having problem calling a session bean from servlet. I got the
following ClassCastException when try to 'narrow' the home interface

Tuxedo calling EJB in pub/sub model

does this call EJB(java)in my WLE Domain 5.1v . does JOLT/JET help in such scenarios?
Just wondering JOLT enabling of the server (the server which subscribes for the

OHADNo, there are certain server features that require 1.3 to operate, but
it's not every weblogic class. JDK 1.2 is supported for clients of 6.0,
