Re: how to run Ejb program on geronimo
Posted by atul12345 <at...@gmail.com>.
Sir this is openejb-jar.xml. I have already mentioned my xml file in previous
mail.
I think there is no solution to specified own jndi name in geronimo instead
of system generated jndi.
if possible how ? Anyone tell me how to resolve this problem........One more
problem is that i want to execute my client to other system means i have
deployed my jar file on server successfully and using client that wanna run
other system call the method which contain in remote interface.means server
running in one system where my jar file deployed and client program run on
other system where i call those method which contain remote interface. so
tell what i have to do for its.
I mean what step i have to follow to run client program to other system.

Re: how to run Ejb program on geronimo
Posted by atul12345 <at...@gmail.com>.
Thanx for response but sir according to you that link u have provided, when i
specified jndi name in openejb.xml and that jndi name call from the client
program, get this exception...........
NamingException:
javax.naming.NameNotFoundException: /foo does not exist in the system.
Check that the app was successfully deployed.
at
org.apache.openejb.client.JNDIContext.lookup(JNDIContext.java:251)
at javax.naming.InitialContext.lookup(InitialContext.java:392)
at Client.main(Client.java:26)
This is my openejb.xml file.........
<openejb-jar xmlns="http://www.openejb.org/xml/ns/openejb-jar-2.1"
xmlns:naming="http://geronimo.apache.org/xml/ns/naming-1.1"
xmlns:security="http://geronimo.apache.org/xml/ns/security-1.1"
xmlns:dep="http://geronimo.apache.org/xml/ns/deployment-1.1">
<enterprise-beans>
<session>
<ejb-name>DemoBean</ejb-name>
<jndi name="foo" interface="My.DemoInter"/>
<!--<ejb-ref>
<ref-name>ejb/CustomerEntityBean</ref-name>
<ejb-link>Entity</ejb-link>
</ejb-ref>-->
</session>
</enterprise-beans>
</openejb-jar>
but when i specified system generated jndi name in client program that run
without any exception.
please anyone know about this problem what i m doing wrong and what step i
have to follow to creating own jndi name..

Re: how to run Ejb program on geronimo
Posted by David Jencks <da...@yahoo.com>.
My apologies for not seeing that you are trying to name your ejb the
same as the spec required MEJB. I recommend you remove the jndi-name
tag from your openejb-jar.xml plan and use the default binding
location that you can see by looking at the log of deployment of your
app.
In the future please examine the environment for signs of errors and
report them all. In this case the deployment error occurred well
before you tried to access the ejb and knowing about it would have
helped give better advice sooner. BTW my previous comment that you
are actually looking up the spec-required MEJB home rather than your
ejb is borne out by the deployment error.
thanks

Re: how to run Ejb program on geronimo
Posted by atul12345 <at...@gmail.com>.
Dear Sir,
Thanks for help but this is not my solution. Anyway sir i have
already provided all code that i am using for simple stateless session
bean.I am using two interface one is remote interface with one method that
is add and second is home interface and one bean class which implements the
sessionBean interface.and two xml which are ejb-jar.xml and other is
openejb.xml.after i created one jar file that include the two interface,one
bean class and two xml which are exist in meta-inf.when i deployed this jar
file into the server that show successfully deployed.bt when i checked
server log file it show Jndi(name=ejb/mgmt/MEJBRemoteHome) cannot be bound
to Ejb(deployment-id=ejbsample1.jar/ejb/mgmt/MEJB). Name already taken by
Ejb(deployment-id=mejb/ejb/mgmt/MEJB).
and when i run my client program get this kind of na error ...........
java.lang.ClassCastException at
com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableR at
javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
at HelloWorld.main(HelloWorld.java:31)
Caused by: java.lang.ClassCastException: $Proxy0 cannot be cast to
org.omg.CORBA at
com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableR
... 2 more
And my client code is
import java.util.*;
import javax.rmi.PortableRemoteObject;
import javax.naming.*;
import javax.rmi.*;
import javax.ejb.*;
import java.rmi.RemoteException;
//import com.prokriti.server.*;
public class Client {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
try {
Properties properties=new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
properties.put("java.naming.provider.url","ejbd://localhost:4201");
//
Context context = new InitialContext(properties);
Object homeObject =
context.lookup("mgmt/MEJBRemoteHome");
System.out.println("ic = "+homeObject);
//Object abc=PortableRemoteObject.narrow(homeObject,
DemoHome.class);
DemoHome home =
(DemoHome)PortableRemoteObject.narrow(homeObject, DemoHome.class);
DemoInter remote =home.create();
//remote.display();
} catch(Exception e) {
System.err.println("NamingException: " + e.getMessage());
}
// catch(RemoteException e) {
// System.err.println("RemoteException: " + e.getMessage());
// } catch(CreateException e) {
// System.err.println("FinderException: " + e.getMessage());
// }
}
}
Problem is i think could not get the correct jndi name. so where to find

Hi,
I sent an earlier response, but it seems to have bounced. Trying again.
Apologies, if this is redundant.
The above stacktrace indicates a "HelloWorld" class. Yet, the code you
supply below is a "Client" class and the line numbers don't match. Thus,
we're not sure what you are actually running with... Please make sure you
are running the code you think you are. Then, if you still have a problem,
give us the code which matches your symptoms.

Re: how to run Ejb program on geronimo
Posted by atul12345 <at...@gmail.com>.
Dear Sir,
Thanks for help but this is not my solution. Anyway according
to u i am showing the ENTIRE stack trace for this exception and include the
exact source code........
This is my Exception which is generated during the client program
execute.......

hearing from you.

Re: how to run Ejb program on geronimo
Posted by David Jencks <da...@yahoo.com>.
Thank you for supplying the code you are actually running. With this
available the mistake is rather obvious:
//Object is a MEJBHome
Object object=ctx.lookup("ejb/mgmt/
MEJBRemoteHome");
//You are casting it to DemoHome
My.DemoHome ejbHome=(My.DemoHome)
PortableRemoteObject.narrow(object,My.DemoHome.class);
The easiest way to determine the correct jndi name to look up is to
examine the server log when you deploy your ejbs, as there will be
log messages indicating where the ejbs are bound.
Many people find it more convenient to rely on the openejb transport
and avoid corba and just cast the result of the jndi lookup rather
than using PortableRemoteObject.narrow. Both will work using the
proprietary openejb transport but the error messages from PRO.narrow
can sometimes be difficult to decipher.
While I doubt it would make any difference in this use of PRO.narrow
to perform a cast using the yoko corba implementation we ship with
geronimo may produce fewer corba related errors.
thanks

Re: how to run Ejb program on geronimo
Posted by atul12345 <at...@gmail.com>.
Dear Sir,
Thanks for help but this is not my solution. Anyway according
to u i am showing the ENTIRE stack trace for this exception and include the
exact source code........
This is my Exception which is generated during the client program
execute.......
java.lang.ClassCastException

Caused by: java.lang.ClassCastException: $Proxy0 cannot be cast to
org.omg.CORBA
at
com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableR

Could anyone tell me what I’m doing wrong? Thanks a lot. Looking forward to
hearing from you.

Re: how to run Ejb program on geronimo
Posted by atul12345 <at...@gmail.com>.
Dear Sir,
Thanks for help but this is not my solution. Anyway according
to u i am showing the ENTIRE stack trace for this exception and include the
exact source code........
This is my Exception which is generated during the client program
execute.......
java.lang.ClassCastException
at
com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableR
at
javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)

Caused by: java.lang.ClassCastException: $Proxy0 cannot be cast to
org.omg.CORBA
at
com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableR
... 2 more
Could anyone tell me what I’m doing wrong? Thanks a lot. Looking forward to
hearing from you.
These are my code..........

Re: how to run Ejb program on geronimo
Posted by David Jencks <da...@yahoo.com>.
We seem to be going around in circles. I don't believe the exception
you show is consistent with the client code you show. Please show
the ENTIRE stack trace for this exception and include the exact
source code as a file so I can see the line numbers from the client
code matching up with the stack trace. I cannot investigate further
without some definite correspondence that I can see clearly between
the pieces of information you supply.
thanks

Re: how to run Ejb program on geronimo
Posted by David Jencks <da...@yahoo.com>.
Are you sure you are running the client code you show? The error
indicates you are using PortableRemoteObject.narrow() rather than the
simple cast in the client code you showed earlier.
Is the CCE happening on the client?
I'm unable to see how the exception you show can be coming from the
code you show. More of the exception stack trace might possibly be
helpful.

Re: how to run Ejb program on geronimo
Posted by Viet Nguyen <vh...@gmail.com>.
Hi Atul,
It looks like you're doing a remote lookup. I think your client code
should look something similar to
My.DemoInter remoteObj =(My.DemoInter)ctx.lookup(<jndi for remote interface>);
Let me know if this works.
Thanks,
Viet

Hi Atul,
I am not sure but did you specify the home and remote
