I am really in need of some help here! I have Visibroker for C++ running on HP-UX. I have a java client attempt to connect to the server using the standard Java ORB implementation with the following code:
<B>Properties props = new Properties();
props.put(&quot;org.omg.CORBA.ORBClass&quot;, &quot;com.sun.corba.se.internal.iiop.ORB&quot;);
props.put(&quot;org.omg.CORBA.ORBSingletonClass&quot;, &quot;com.sun.corba.se.internal.iiop.ORB&quot;);
props.put(&quot;ORBInitialHost&quot;, &quot;10.80.62.30&quot;);
props.put(&quot;ORBInitialPort&quot;, &quot;140015&quot;);
org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init((String[])null, props);
org.omg.CORBA.Object objRef = orb.resolve_initial_references(&quot;NameService&quot;);
</B>

An exception is thrown when I hit this line:
<B> org.omg.CORBA.Object objRef = orb.resolve_initial_references(&quot;NameService&quot;);
</B>

The exception is:
org.omg.CORBA.COMM_FAILURE: minor code: 1398079490 completed: No
at com.sun.corba.se.internal.iiop.IIOPConnection.writeLock(IIOPConnection.java:919)
at com.sun.corba.se.internal.iiop.IIOPConnection.send(IIOPConnection.java:980)

Has anyone been able to connect the standard Java ORB Implementation with Visibroker for C++?

Can anyone provide any examples of what the process is to do so?

Any help would be greatly appreciated!

//Visibroker Test Stub (idl2java)
import ksc_objects_vb.*;
import java.io.*;
import org.omg.CosNaming.*;

public class nvb_testStub
{
public static void main(String args[])
{
try {
org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args,null);

String filename = &quot;ns.ior&quot;;
FileInputStream fis = new FileInputStream(filename);
DataInputStream dis = new DataInputStream(fis);
String ior = dis.readLine();

org.omg.CORBA.Object rootObj = orb.string_to_object(ior);

NamingContextExt root = NamingContextExtHelper.narrow(rootObj);
NameComponent nc = new NameComponent(&quot;arborManager&quot;, &quot;&quot;);
NameComponent[] n = {nc};
org.omg.CORBA.Object obj = ((NamingContext)root).resolve(n);

Arbor arbor = ArborHelper.narrow(obj);
long cnt = arbor.getCount();

System.out.println(cnt);

} catch(Exception e) {
System.out.println(&quot;STUPID Error : &quot; + e);
e.printStackTrace(System.out);
}
}
}


too little too late most likely but here is a working example... Hope this helps
