Hello,

Thank you for your help sir.

The service interface:

package chatserver;

import java.util.List;

import org.osoa.sca.annotations.Remotable;

@Remotable
public interface ChatServer {
    List<String> checkMessages(int received);
}

The wsdl file:

My java client:

package sca.client;

import java.util.List;

import org.osoa.sca.annotations.Reference;
import org.osoa.sca.annotations.Service;

import chatserver.ChatServer;

@Service(Runnable.class)
public class ChatClient implements Runnable {

    @Reference
    protected ChatServer cs;

    @Override
    public void run() {

        List<String> arr = (List<String>) cs.checkMessages(0);
        for (String str : arr) {
            System.out.println(arr);
        }

    }

}

The exception:
