by huyiping2007
first,run -c all,i can see that CounterBean is deployed successfully in the following:
09:44:04,046 INFO [JmxKernelAbstraction] creating wrapper delegate for: org.jbo
ss.ejb3.stateless.StatelessContainer
09:44:04,078 INFO [JmxKernelAbstraction] installing MBean: jboss.j2ee:jar=count
er.jar,name=CounterBean,service=EJB3 with dependencies:
09:44:05,406 INFO [EJBContainer] STARTED EJB: com.jboss.ejb3.CounterBean ejbNam
e: CounterBean
09:44:05,687 INFO [EJB3Deployer] Deployed: file:/E:/jboss-4.2.0.GA/server/all/d
eploy/counter.jar
second,my client code is in the following:
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.jboss.ejb3.RemoteCounter;
public class Client {
public Client() {
super();
// TODO Auto-generated constructor stub
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Context ctx = null;
try
{
ctx = new InitialContext();
RemoteCounter counter = (RemoteCounter) ctx.lookup("counter/remote");
System.out.println(counter);
counter.add(10);
System.out.println("the number:" + counter.getNumber());
}
catch (NamingException e)
{
e.printStackTrace();
}
}
}
third,run client class,and the result is in the following.the blue section is client counterbean instance that is printed in the client program :
jboss.j2ee:jar=counter.jar,name=CounterBean,service=EJB3
