1. Accessing Attribute Values

import org.omg.CORBA.DynAny;
import org.omg.CORBA.DynAnyFactory;
import org.omg.CORBA.ORB;

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

        // Create a DynAny instance
        DynAnyFactory factory = orb.create_dyn_any_factory();
        DynAny dynAny = factory.create_dyn_any(orb.create_interface_tc("Person"));

        // Set attribute values
        dynAny.insert_string("name", "John Doe");
        dynAny.insert_double("age", 30.0);

        // Get attribute values
        String name = dynAny.get_string("name");
        double age = dynAny.get_double("age");

        // Print attribute values
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
    }
}

2. Setting Sequence Values

import org.omg.CORBA.DynAny;
import org.omg.CORBA.DynAnyFactory;
import org.omg.CORBA.ORB;

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

        // Create a DynAny instance
        DynAnyFactory factory = orb.create_dyn_any_factory();
        DynAny dynAny = factory.create_dyn_any(orb.create_sequence_tc(0, orb.create_string_tc()));

        // Set sequence values
        dynAny.insert_sequence(0, orb.create_sequence(new String[] {"John Doe", "Jane Doe", "Bill Smith"}));

        // Get sequence values
        String[] names = dynAny.get_sequence().to_string_array();

        // Print sequence values
        for (String name : names) {
            System.out.println(name);
        }
    }
}

3. Accessing Nested Structures

import org.omg.CORBA.DynAnyFactory;
import org.omg.CORBA.ORB;

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

        // Create a DynAny instance
        DynAnyFactory factory = orb.create_dyn_any_factory();
        DynAny dynAny = factory.create_dyn_any(orb.create_struct_tc("Person", new String[] {"name", "age"}, new org.omg.CORBA.TypeCode[] {orb.create_string_tc(), orb.create_double_tc()}));

        // Set nested structure values
        DynAny nameDynAny = factory.create_dyn_any(orb.create_string_tc());
        nameDynAny.insert_string("name", "John Doe");
        DynAny ageDynAny = factory.create_dyn_any(orb.create_double_tc());
        ageDynAny.insert_double("age", 30.0);

        dynAny.insert_DynAny("person", nameDynAny);
        dynAny.insert_DynAny("age", ageDynAny);

        // Get nested structure values
        DynAny personDynAny = dynAny.get_DynAny("person");
        String name = personDynAny.get_string("name");
        DynAny ageDynAny = dynAny.get_DynAny("age");
        double age = ageDynAny.get_double("age");

        // Print nested structure values
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
    }
}

4. Using DynAny with Callbacks

import org.omg.CORBA.DynAny;
import org.omg.CORBA.DynAnyFactory;
import org.omg.CORBA.ORB;
import org.omg.PortableServer.POAManager;

public class DynAnyCallbackExample {
    public static void main(String[] args) {
        // Initialize ORB and POA
        ORB orb = ORB.init(args, null);
        POAManager poaManager = orb.get_current().get_POA().get_POAManager();

        // Create a DynAny instance
        DynAnyFactory factory = orb.create_dyn_any_factory();
        DynAny dynAny = factory.create_dyn_any(orb.create_string_tc());

        // Set callback object
        poaManager.activate();
        dynAny.set_boxed_value(new CallbackObject());
    }

    public static class CallbackObject {}
}

5. Passing DynAny to a Remote Method

import org.omg.CORBA.DynAny;
import org.omg.CORBA.DynAnyFactory;
import org.omg.CORBA.ORB;
import org.omg.CORBA.Object;

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

        // Create a DynAny instance
        DynAnyFactory factory = orb.create_dyn_any_factory();
        DynAny dynAny = factory.create_dyn_any(orb.create_string_tc());

        // Set DynAny value
        dynAny.insert_string("", "Hello");

        // Resolve a remote object reference
        Object obj = orb.string_to_object("localhost:1050#server");

        // Invoke a remote method with DynAny as an argument
        obj.invoke("processDynAny", new org.omg.CORBA.NVList(), dynAny);

        DynAny dynAny = factory.create_dyn_any(orb.create_exception_tc("PersonException", new String[] {"message"}, new org.omg.CORBA.TypeCode[] {orb.create_string_tc()}));

        // Set exception values
        dynAny.insert_string("message", "Something went wrong");
