--------------------------------------------------------------
I use myeclise +
jboss-5.1.0.GA + jdk1.6
service code like this
@Remote
public interface IHelloEJBService {
public String sayHelloEJB(String name);
}
@Stateless
public class HelloEJBService implements IHelloEJBService {
public String sayHelloEJB(String name) {
// TODO Auto-generated method stub
String msg = "hello" + name + ", Welcome to EJB world!";
System.out.print(msg);
return msg;
}
}
then I deploy the service。
I create a new java client project，code like this
public class TestClient {
private static Context context;
/**
* @param args
*/
public static void main(String[] args) {
try
{
Context ctx = getInitialContext();
Object object = ctx.lookup("HelloEJBService/remote");
IHelloEJBService service= (IHelloEJBService)PortableRemoteObject.narrow(object, IHelloEJBService.class);
System.out.println(service.sayHelloEJB("Client "));
}
catch(Exception e)
{
e.printStackTrace();
}
}
protected static Context getInitialContext() throws Exception
{
if(context == null)
{
Hashtable props = new Hashtable();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
context = new InitialContext(props);
}
return context;
}
}
I copy all jars of D:\jboss-5.1.0.GA\client\ to client project and add all to classpath.
run the client code ，occur exception
