Hi,

Thanks for all your focus on the problem. The problem is resolved now. There were two issues.

The first problem was that, the contents of the jar file was invalid. It has the top level directories also.
For jndi.properties, was not accessible in the classpath, some how.

Both of these problems have been resolved and my first bean started working.

Thanks & Regards,
Ravi

Hi,

The contents of the JAR seems to be invalid. And thanks for pointing me to the contents of the jar. I have re-created the jar file that contains the following contents:
C:\jboss-6.0.0\server\default\deploy>jar -tf HelloWorldEjb.jar
META-INF/
META-INF/MANIFEST.MF
example/HelloWorldBean.class
example/HelloWorldInt.class

After this trail, the JBOSS6 server is responding with a message that it has considered the jar for deployment as follows:

HelloWorldBean/remote - EJB3.x Default Remote Business Interface
HelloWorldBean/remote-example.HelloWorldInt - EJB3.x Remote Business Interface

18:22:20,437 WARN [org.jboss.ejb3.TimerServiceContainer] EJBTHREE-2193: using deprecated TimerServiceFactory for restoring timers


But still, when i am trying to run the client code, it is throwing the following exception:

[color=darkred]D:\EJB3Dev\simple-ejb\classes>java -cp %JBOSS_HOME%\client\jbossall-client.jar;. example.ClientEjb
about to lookup the JNDI name:java:comp/env/ejb/HelloWorldBean

Hi,

I am newbie to EJB3 and started my first example with JBOSS6 installed in my machine.

I am able to run the server and When i deploy the ejb jar file into "%JBOSS_HOME%\server\default\deploy\" directory, it is not showing any message saying that the bean or the application has been deployed.

Also when i am trying to access the same with standalone client, it is throwing the following Exception...
i would appriciate any help in resolving this issue.

D:\EJB3Dev\simple-ejb\src>java -cp %JBOSS_HOME%\client\jbossall-client.jar;.\..\classes;. example.ClientEjb
about to lookup the JNDI name:java:comp/env/ejb/HelloWorldBean
log4j:WARN No appenders could be found for logger (org.jnp.interfaces.TimedSocketFactory).
