Problem:

Product: VBJ 5.x
Platform: All
JDK: Not applicable.
Component: Visinotify

1. How to destroy Visinotify Channel?

2. What is the reason for the following exception thrown:

org.omg.CORBA.NO_PERMISSION: minor code: 4F4D0000 completed: No at java.lang.Class.newInstance0(Native Method)
at java.lang.Class.newInstance(Class.java:262)

Resolution:

Below is the example to destroy Visinotify Channel

[Example.java]

import org.omg.CORBA.IntHolder;
import org.omg.CORBA.ORB;
import org.omg.CosNotification.Property;
import org.omg.CosTypedNotifyChannelAdmin.TypedEventChannel;
import org.omg.CosTypedNotifyChannelAdmin.TypedEventChannelFactory;
import org.omg.CosTypedNotifyChannelAdmin.TypedEventChannelFactoryHelper;

public class Example { public static void main(String[] args)

{
    try
    {
        ORB orb = ORB.init(args, null);
        TypedEventChannelFactory factory = TypedEventChannelFactoryHelper.narrow(orb.resolve_initial_references("TypedNotificationService"));
        TypedEventChannel channel = factory.create_typed_channel(new Property[] {}, new Property[] {},
        new IntHolder());
        System.out.println("created Channel");
        System.out.println("calling Destroy Channel .....");
        channel.destroy();
        System.out.println("Channel destroyed sucessfully .....");
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

To run:
vbjc Example.java osagent & visinotify & vbj Example

The exception "org.omg.CORBA.NO_PERMISSION: minor code: 4F4D0000 completed: No" does occur with BES 5.1 Visinotify, but not with BES 5.2.1 Visinotify. A workaround is to upgrade to BES521.
