Then you need to add the jboss-*.properties to the Eclipse 'Run Configurations' for this class.

Hi Oliver,

I placed the jboss-ejb-client.properties in the class path of my (remote) client application, but still am able to get the remote object, but by invoking the method am getting the exception.
Can u please share your code how to invoke your ejb remote bean object and calling the method inside the bean remote object

As this is the normal behaviour of the client. The 'lookup' will never call the server!
So you get an exception if you access the bean.

For examples you might have a look into the quickstarts (or clone/download it) :
git clone git://github.com/jboss-jdf/jboss-as-quickstart.git

ejb-remote, cluster-ha-singleton-service and ejb-multi-server contain clients that will use what you will see.
See the description and documentation here, also each quickstart will have a README.md

System.setProperty("jboss.ejb.client.properties.file.path", "C:\\jboss-ejb-client.properties"); // Content of the file I posted already.

Properties properties = new Properties();
properties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
Context jndiContext = new InitialContext(properties);

Object ref = jndiContext.lookup( "ejb:/MtzWebComm//CommEJB!de.miditec.communication.ejb.CommEJBHome");
CommEJBHome commEJBHome = (CommEJBHome) PortableRemoteObject.narrow(ref, CommEJBHome.class);

CommEJB commEJB = commEJBHome.create(1);

System.out.println( commEJB.getHello() );
commEJB.remove();

So, it's similar to your code.

Are Client and JBoss on different machines?

If yes, you need to set in the properties files also username and password, because security-realm is enabled by default.
remote.connection.default.username=xxx
remote.connection.default.password=yyy

Only if the client runs locally you don’t need to set the username/password.

My client and JBoss are running in same machine.

i tried with username and password also.

In the JBoss Console am getting the below error

To eliminate influence of other components (e.g. Windows - I suppose you use this - Firewalls etc)
are you able to run one of the quickstarts successfully?

For AS7 you should use the jar file in the JBOSS/bin/client folder, see the instructions in the README file for informations about jar and mavaen use.

Below i pasted the code of the Home interface class

package Home;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
import Remote.JMSRARemote;
public interface JMSRAHome extends EJBHome{
public JMSRARemote create() throws RemoteException, CreateException;
}

And below is the code for Remote class

package Remote;
import java.rmi.RemoteException;
import java.util.ArrayList;
import java.util.Vector;
import javax.ejb.EJBObject;
public interface JMSRARemote extends EJBObject{
public String ReadTxnFromInputQueueString(String strQName)throws RemoteException;
}

Is this code is correct?

I created a sample class file (LookUp_Bean.java) and having the code for getting the remote object and I run this class files and here it’s working fine am getting the remote object and am able to call the methods inside the ejb bean.
But from my client application if I run means it’s not working. In this case the main class is different class and from the main class am calling the (LookUp_Bean.java) class for getting the remote object. Both times am using same method. Am getting below exception.
I placed the properties file in the class path of the client application
