Ok, I finally got my environment to work again and I am having the same
problems. I use the example exactly the way it is and I am getting the same
errors. This is the stack trace
java.lang.RuntimeException: Invalid response from server: -1
at org.apache.openejb.client.JNDIContext.lookup(JNDIContext.java:292)
at javax.naming.InitialContext.lookup(Unknown Source)
at appclient.ApplicationClient.main(ApplicationClient.java:32)

Subject: RE: JNDI in Geronimo 2
I want to thank you Wang, Tang and everyone else who has helped me. I have
tried everyone's suggestions and have even ran through the tutorial exactly the
way it is on the site with no success. This leads me to believe that there is
something wrong with my installation of Ganymede. I have since cleaned out all
of the plug-ins associated with the Geronimo App Server. Upon trying to
reinstall the plug-ins, I got errors saying that it could not be installed. I
will need to figure out what is wrong before I can continue. I think that once
I have those environment issues worked out, I will be fine. I will keep you
guys posted.

BTW
you should add
repository\org\apache\openejb\openejb-client\3.0\openejb-client-3.0.jar
to your client's build path.

Russell, could you provide the whole exception strack?
I can not got your problem.
here is my code:
public class Client {
public static void main(String[] args) throws Exception {
try {
Properties p = new Properties();
p.setProperty("java.naming.factory.initial",
"org.apache.openejb.client.RemoteInitialContextFactory");
p.setProperty("java.naming.provider.url", "ejbd://localhost:4201");
InitialContext context = new InitialContext(p);
FirstObjectRemote obj= (FirstObjectRemote)
context.lookup("FirstObjectBeanRemote");
System.out.println(obj.hello("Rex"));
} catch (Exception e) {
e.printStackTrace();
}
}
}
I try it with Tang's EJB code as follows:
import javax.ejb.Stateless;
@Stateless
public class FirstObjectBean implements FirstObjectRemote{
public String hello(String name){
return "Hello " + name;
}
}
import javax.ejb.Remote;
@Remote
public interface FirstObjectRemote {
public String hello(String name);
}

Thank you Wang and Tang. Here are the things that I have done.
* Changed the JDK to version 1.5.0_6
* Updated all of my classes to use this version of Java
* Changed the provider url to ejbd://localhost:4201
I get the error
java.lang.RuntimeException: Invalid response from server: -1

Yes, should be ejbd://localhost:4201. The same as the example in the
doc<http://cwiki.apache.org/confluence/display/GMOxDOC22/Deploying+and+running+EJB+application+clients>.

Tang, I believe Russell use a remote client, but not a application client.
to Russell, try "ejbd://localhost:4201"
Rex.

Hi Russell,
I suggest you use JDK 1.5 instead of 1.6. It is also recommended that Eclipse
and Geronimo use the same Java environment.
Please let me know if there is still any problem.

Thank you Tang. This should be real strait forward but there has got to be
some reason why this is not working. Here is the configuration that I have.
This may help in solving this issue.
Eclipse Ganymede
Java 1.6..0_11
Geronimo 2.1.2
Geronimo 2.1.3 (tried it on both)
There are a couple of other things that I tried that gave me different results.
1. Added a runtime dependency to the Geronimo Runtime. This gave me a
different error. It was a java runtime error that said that the response from
the server is: -1
2. Created a client j2ee application to run my app.
Basically, I am following everything in that link that you sent me. I am just
getting these errors when trying to look up the object. Any more insight would
be greatly appreciated.

Hi Error! Filename not specified.Russell,
I tried your example on Geronimo 2.1.4.
1. I renamed the implementation class as FirstObjectBean. A bit different
from your code:
---------------------------------------------------
@Stateless
public class FirstObjectBean implements FirstObjectRemote { import
public String hello(String name){
return "Hello " + name;
}
}
---------------------------------------------------
2. In the application client that referece the EJB, I used
---------------------------------------------------
import ejb.FirstObjectRemote;
...
FirstObjectRemote firstObject =
(FirstObjectRemote)context.lookup("FirstObjectBeanRemote");
---------------------------------------------------
3. Add the EJB project to the build path of the application client project.
4. Add the two projects to the Geronimo server, and run the application client.
The application works well and the "Hello Russel" message shows up.
For more detailed information, please refer to:
http://cwiki.apache.org/confluence/display/GMOxDOC22/Deploying+and+running+EJB+application+clients
Hope this helps.

Hello. I am new to the list, new to EJB 3.0 and new to Geronimo 2. I am
pretty sure I understand all of the concepts but I am having an issue with a
JNDI lookup in Geronimo. I have created a Bean and it looks as follows.
Interface:
@Remote
public interface FirstObjectRemote {
public String hello(String name);
}
Class:
@Stateless
public class FirstObject implements FirstObjectRemote {
public FirstObject() {
}
@Override
public String hello(String name){
return "Hello " + name;
}
}
Everything deploys just fine (at lease I think it does). I created a test
class:
public class TheClass
{
public static void main(String[] args)
{
Properties prop=new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
prop.put(Context.PROVIDER_URL, "ejbd://localhost:1099");
try{
Context context = new InitialContext(prop);
FirstObjectRemote firstObject =
(FirstObjectRemote)context.lookup("FirstObjectRemote");
System.out.println(firstObject.hello("Russell"));
}
catch(Exception ex){
System.out.println(ex.toString());
}
}
}
I get an error I when trying to run this. The error that comes back is:
javax.naming.NamingException: Cannot lookup '/FirstObjectRemote'. [Root
exception is java.rmi.RemoteException: Error while communicating with server: ;
nested exception is:
java.lang.NoClassDefFoundError: javax/transaction/RollbackException]
What am I missing?
