Answer 1

1) Load the Dozer bean mapper from mapping file

DozerBeanMapper dtoMapper = new DozerBeanMapper(Arrays.asList(new String[]{dozerMappingfile}));

2) Covert each object to a normal object removing persistentbag related details

List<MyEjb>  lstProfilehib =  //hibernate loaded objects
        List<MyEjb>  lstProfile  = new ArrayList<MyEjb>();
        for(MyEjb sp: lstProfilehib){
            lstProfile.add( dtoMapper.map(sp, MyEjb.class)); 
        }

NHibernate serialization has been treated a lot on stackoverflow. See:

• C# Castle ActiveRecord: How to elegantly (XML) serialize ActiveRecord objects?
• How do I serialize all properties of an NHibernate-mapped object?
• NHibernate and WCF Serialization(Unidirectional)
• JSON.NET and nHibernate Lazy Loading of Collections
• Which .NET JSON serializers can deal with NHibernate proxy objects?
• DTOs vs Serializing Persisted Entities
• Returning NHibernate mapping classes from WCF services

Bottom line: use DTOs.

Answer 3

You can never XML Serialize an interface - only a concrete class that implements the interface.

Answer 4

Try using the DataContractSerializer instead. It's more restrictive, but will serialize more.

Dan Rigsby explains the difference between XMLSerializer and DataContractSerializer

Here's an example from one of my posts on stackoverflow:

public XDocument GetProductXML(Product product)
    {
        var serializer = new DataContractSerializer(typeof(Product));
        var document = new XDocument();

        using (var writer = document.CreateWriter())
        {
            serializer.WriteObject(writer, product);
            writer.Close();
        }

        return document;
    }
