           Summary: Cannot encode Objects contained within structs
           Product: JacORB
           Version: 1.4.0
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ORB
        AssignedTo: gerald.brose@acm.org

This is bug 74 raised again because that problem was not entirely fixed.
The problem only appears to have been fixed for null Object references.

The following code demonstrates the problem.
(ActionImpl is a trivial servant implementation)

------------------------------
dummy.idl

   struct DummyIfc
   {
        Object val;
   };

--------------------
TestCodec.java


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

            POA poa =POAHelper.narrow(orb.resolve_initial_references("RootPOA"));
            POAManager manager = poa.the_POAManager();
            manager.activate();
            Servant servant = new ActionImpl();
            byte[] oid = poa.activate_object(servant);
            org.omg.CORBA.Object ref = poa.id_to_reference(oid);

            Any any = ORB.init().create_any();
            DummyIfcHelper.insert(any, new DummyIfc(ref));  //## must have ref
            CodecFactory cf = CodecFactoryHelper.narrow(
                orb.resolve_initial_references("CodecFactory"));
            byte majorEncoding = Byte.parseByte("1");
            byte minorEncoding = Byte.parseByte("0");
            Encoding encoding = new Encoding(ENCODING_CDR_ENCAPS.value,
                                             majorEncoding, minorEncoding);
            Codec codec = cf.create_codec(encoding);
            byte[] data = codec.encode_value(any);

            System.out.println ("Codec Test OK");
        }
        catch (Exception e)
        {
            System.err.println("FAILED: " + e);
            e.printStackTrace();
        }
    }
}
