Compiling first example

[Иван Бишевац]

Hi, I am new to River and want to setup my first project. I downloaded River
source code and built it with command:
ant build.all
After that I went to $RIVER_HOME/examples/hello and started services and
after that started example by invoking ant command. That's ok.

But now I want to run some example with Eclipse. I started with:
http://river.apache.org/user-guide-basic-river-services.html . I started
HTTP Server, started Service Registrar.
After that I made this class:

import java.rmi.MarshalledObject;
import java.rmi.RMISecurityManager;
import java.rmi.RemoteException;

import net.jini.core.discovery.LookupLocator;
import net.jini.core.event.EventRegistration;
import net.jini.core.event.RemoteEventListener;
import net.jini.core.lookup.ServiceID;
import net.jini.core.lookup.ServiceItem;
import net.jini.core.lookup.ServiceMatches;
import net.jini.core.lookup.ServiceRegistrar;
import net.jini.core.lookup.ServiceRegistration;
import net.jini.core.lookup.ServiceTemplate;

public class Test implements ServiceRegistrar{
public static void main(String[] args){
System.setSecurityManager(new RMISecurityManager());
 getUnicast();
}
public static void getUnicast(){
 LookupLocator ll = new LookupLocator("jini://localhost:4160");
StreamServiceRegistrar sr = ll.getStreamRegistrar();
 System.out.println("Service Registrar: "+sr.getServiceID());
}

        //Here goes other methods
}


My problem is that Eclipse tells me StreamServiceRegistrar cannot be
Resolved to a type. Obviously I didn't imported library which contains this
class. But I imported all jars from folder $RIVER_HOME/examples/hello/lib.
Also nothing changes if I import all jars from
$RIVER_HOME/lib, $RIVER_HOME/lib-dl and $RIVER_HOME/lib-ext.

Cant someone help me?
