hello ,
I'm so sorry that I skiped one words. so pls take this as the more specific one.
I rewrite the client program of echo example with java,but it report some errors.
here is my step. both the client and server progam run in the same machine.
1. star Namer service.

Checkpointing completed.
2. as to ther server side, its code is identical to eg3_impl.cc. I change nothing.
star the server
3. first, I started the C++ client as the OmniORB distribution offered.and it work fine.

4, then I begin start the java client,
this is the client code:
import org.omg.CosNaming.*;
import org.omg.CORBA.*;
public class EchoClient
{
public static void main(String args[])
{
try{
String SetInfo,ReturnInfo,ref;
org.omg.CORBA.Object objRef;
Echo EchoRef;
ORB orb = ORB.init(args, null);
objRef = orb.resolve_initial_references("NameService");
NamingContext ncRef = NamingContextHelper.narrow(objRef);
// locate the service
NameComponent nc = new NameComponent("Echo", "");
NameComponent path[] = {nc};
EchoRef = EchoHelper.narrow(ncRef.resolve(path));
if (args.length>1)
{
SetInfo=args[1];
}
else
{
}
System.out.println("Client Process Begin: ");
ReturnInfo = EchoRef.echoString("my corba test");
System.out.println(ReturnInfo);
} catch (Exception e) {
System.out.println("ERROR : " + e) ;
}
}
}
in the console ,
i typeed java EchoClient :
[root at redhat corba]# java EchoClient
ERROR : org.omg.CORBA.INTERNAL: vmcid: SUN minor code: 208 completed: No
then I met the errors above, could anyone give me some advice?
thanks a lot!
Best regards
Simon
