I am trying to create a web service from the following java class:

import com.corda.cvserver.admin.AdminBean;
import com.corda.cvserver.CordaDataStore;
import java.rmi.*;
import java.rmi.registry.*;

public class CVPassword {
	
	private static String registryAddress = "localhost";
	private static int registryPort = 1234;
	private static String adminUsername = "Admin";
	private static String  adminPassword=CordaDataStore.encryptPassword("admin");

public String heyprint(){
		return "hey";
	}
	
	public static AdminBean getAdminBean()
	{
		Remote object = null;

Registry registry = null;
		try
		{
			registry = LocateRegistry.getRegistry(registryAddress, registryPort);
			System.out.println("I was able to locate the registry! maybe...");
			System.out.println("registry.toString(): " +registry.toString());
			System.out.println("AdminBean.RMI_OBJECT_NAME: " + AdminBean.RMI_OBJECT_NAME);
			
			object = registry.lookup(AdminBean.RMI_OBJECT_NAME);
		}
		catch(RemoteException e)
		{
			System.out.println("the Remote Exception caught me");
			e.printStackTrace();
		}
		catch(NotBoundException e)
		{
			System.out.println("the Not Bound Exception caught me");
			e.printStackTrace();
		}

if(object == null)
		{
			System.out.println("The registy returned a null object!");
		}
		AdminBean remoteAdmin = null;
		if(object != null && object instanceof AdminBean)
		{
			remoteAdmin = (AdminBean)object;
		}
		else
		{
			System.out.println("Unable to retrieve object from remote registry");
		}
		return remoteAdmin;
	}

}

// end of class

While creating the web service and I first get this warning:
The service class "CVPassword" does not comply to one or more requirements of the JAX-RPC 1.1 specification, and may not deploy or function correctly.
The value type "com.corda.cvserver.admin.AdminBean" used via the service class "CVPassword" does not have a public default constructor. Chapter 5.4 of the JAX-RPC 1.1 specification requires a value type to have a public default constructor, otherwise a JAX-RPC 1.1 compliant Web service engine may be unable to construct an instance of the value type during deserialization.

I dont think this would cause a problem because I am not returning an instance of
adminBean from any function.

The webservice starts up fine and just for testing purpose i want to see if my heyprint method could be invoke, but when I try to do so I get this error:

Why does adminBean have anything to do with my heyprint method?
Here is the wsdl file if that helps at all

I checked the errors and found under warnings:

Classpath entry C:/Documents …/CenterViewServer.jar will not be exported or published. Runtime ClassNotFoundExceptions may result.

Fell like this should have gone under errors...

This lead to quick fix that solved my problems:
Mark the associated raw classpath entry as a publish/export dependency.
