Hi all
I am using LFR 6, I need to call the user service from external server.
I know that Liferay exposes its services for remote calls using Hessian, Burlap to name a few.
I am using Hessian.
So when i make a call from Hessian client whcih is a standalone program running on command prompt.
I get following error
INFO: No server detected

My code is something like
HessianProxyFactory factory = new HessianProxyFactory();
factory.setUser("test");
factory.setPassword("test");
System.out.println(factory.toString());
UserService service = null;
service = (UserService) factory
.create(
UserService.class,
url);
System.out.println(service.toString());
System.out.println("1111111111111111111");
User user = service.getUserById(10169);
System.out.println(user);
Any idea how to get this reflection error removed. Any suggestion will be appreciated
Thanks
Rishi
