Whe I don't get remote access on my ejb?I
I get this error message, if my client app try to communicate with my server app:

Java Result: 1
I created a simple ejb "HelloBean.ear" with the following two files:
- Hello.java (The interface)
- HelloBean.java (implements my Interface)
The content of Hello.java is:
package examples.session.stateless;
public interface Hello {
public String hello();
}
The content of HelloBean.java is:
package examples.session.stateless;
import javax.ejb.Stateless;
import javax.ejb.Remote;
@Stateless
@Remote(Hello.class)
public class HelloBean implements Hello{
@Override
public String hello(){
String result;
result = "Hallo!";
return result;
}
}
I successfully deployed my ejb on the jboss server. This is the output of the server's log file:
12:54:48,334 INFO [org.jboss.as.server.deployment] (MSC service thread 1-2) JBAS015876: Starte Deployment von "HelloBean.ear" (runtime-name: "HelloBean.ear")

Furthermore I created a client app with the following files:
- jboss-ejb-client.properties
- jndi.properties
- HelloClient.java
The content of the "jboss-ejb-client.properties"-file is: endpoint.name=client-endpoint remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false remote.connections=default remote.connection.default.host=10.7.97.48 remote.connection.default.port = 4447 remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false remote.connection.default.username=xxxxxx remote.connection.default.password=xxxxxx
The content of the "jndi.properties"-file is:
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory java.naming.factory.url.pkgs=org.jboss.ejb.client.naming jboss.naming.client.ejb.context=true java.naming.provider.url=remote://10.7.97.48:4447 java.naming.security.principal=xxxxxxx java.naming.security.credentials=xxxxxxx
The content of the "HelloClient.java"-file is:
package examples.session.stateless;
import java.util.Hashtable;
import java.util.Properties;
import javax.naming.*;
import org.jboss.ejb.client.EJBClientContext;
import org.jboss.ejb.client.PropertiesBasedEJBClientConfiguration;
import org.jboss.ejb.client.remoting.ConfigBasedEJBClientContextSelector;
public class HelloClient{
public static void main(String[] args) throws Exception{
final String appName = "HelloBean";
final String moduleName = "HelloBean-ejb";
final String distinctName = "";
final String beanName = HelloBean.class.getSimpleName();
final String viewClassName = Hello.class.getName();
System.out.println("Looking EJB via JNDI ");
String ejbName = "ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName;
System.out.println(ejbName);
final Hello ejb = (Hello) InitialContext.doLookup(ejbName);
String result = ejb.hello();
System.out.println(result);
}
}
I can ping my server with the ip 10.7.97.48.
In my webbrowser I can see the application platform with the ip 10.7.97.48 and with the port 8081.
Why my client app don't get access on my ejb?
